Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

[ Bitcoin ] Could blockchain be used to secure voting?

[ 🔴 DELETED 🔴 ] Topic originally posted in Bitcoin by foxy-agent [link]
Hi everyone, I recently started reading about Bitcoin and have become really intrigued by the concept of the blockchain to authenticate transactions as a master ledger. While this is obviously great for financial records, my brain made a connection outside the box for a use case: voting. I like participating in my democracy, and assume others do too, but standing in line at the polls, risking your health, getting time off from work or finding a ride to a voting location an demotivate you from participating. I wish it were easier, like online banking, but after so many news stories of companies getting hacked and losing user data it’s really scary to think that so much information & power could be manipulated by just one system. For the moment, a diversified node system seems to be the most secure.
But I would love to see a day come when voting is as easy as downloading an app to my phone and logging a vote. Authentication for log-in could be based on matching a SSN to some kind of 2-factor authentication info (USPS mailer card with PIN?). But even with a way to verify one real person with one vote, a centralized system is a major target for hacking.
So my question is, could blockchain be used to authenticate voter roles? I believe it could, although I see there is a limit to the number of transactions per block, which might limit the number of votes that could be recorded in a given time frame. One solution might be a very large block, since the chain would not be that long, but another solution to handle the throughput of millions of votes cast in one day could be several smaller chains that tie into a larger chain, like a reverse fork? Each state (or county) run a blockchain and then send their independent results to a larger blockchain?
For example, several cities in a county could collect votes from 12am to 11:59pm, and then the balance of their transactions (the votes) could be submitted to county or a state’s ledger, and then the state could submit their ledger to the national ledger, and it would all be verified with blockchain.
Anyway, would really appreciate any input to this idea.

Introducing r/FortNiteBR Bricks

Introducing FortNiteBR Bricks
UPDATE (6/1): You may notice some changes in the feature with the new iOS app release. We're working closely with Apple and will share updates as available.
***
TL;DR: Bricks are a new way for people to be rewarded for their contributions to FortNiteBR. Claim your Bricks in the new Vault section of the Reddit iOS or Android app! They are owned entirely by you, they show up next to your username, and they can be transferred, tipped, and spent in FortNiteBR.

https://preview.redd.it/djx80qikmly41.png?width=1200&format=png&auto=webp&s=dcec52e363348eb9d3f984a32abbb18a374d6cd9
Today we’re launching a new feature in limited communities called Community Points. Community Points are a way for users to be rewarded for their contributions with a piece of the subreddit. Community Points can be earned, tipped, won, collected, and spent on unique items within a community. Each subreddit has its own stylization of Community Points, and the ones in FortNiteBR are called Bricks.
A Brick

How do you get Bricks?

Bricks are distributed monthly based on individual contributions (comments, posts, etc.) that people make in FortNiteBR. Reddit karma provides a basis for measuring people’s contribution, but the final decision is up to the community.

What can you do with Bricks?

Bricks can be traded freely and used for any number of purposes within the community. At this time, they can be used to display reputation within the subreddit, unlock exclusive features like badges and GIFs in comments with a Special Membership, and add weight to votes in polls.
Note: Bricks are not affiliated with Epic Games.

On the Blockchain

Bricks exist on the Ethereum blockchain, independently of Reddit, where they can only be controlled by you (just like Bitcoin!). This means once you’ve earned them and they’re in your Vault, neither Reddit nor moderators can take your Bricks away or decide what you do with them. They’re all yours.

How to get started with your Reddit Vault

The first Bricks will soon be distributed to every active contributor in the subreddit with at least 100 karma. You can get started by claiming your Bricks in the new Vault section of the Reddit mobile app, which also includes more details on the start-up process and how Bricks work.
Please note that you will need to set up your Vault the first time you access it, and you will need to be on the latest version of the Reddit app (2020.17.0 or later). We will be rolling the Vault out over the course of the day, so if you don’t see it now, please check back later.
See the inspiration for Community Points and get started

Thank you FortNiteBR

We are launching Community Points today in a couple of subreddits that have opted into this experiment and with whom we have been working closely. As some of you know, our team has been developing features for FortNiteBR for over a year now. We are very excited to launch our biggest project yet and hear what you think. None of this would be possible without your continued help and support. So thank you!
We’ll be sticking around to answer any questions you have, so please ask away in the comments below.

dxDAO aims to power DeFi protocols through decentralized governance

I found this article on internet. It's repost of it to help educate people about all DXDao advantages:
These are positive and necessary steps for DeFi. The new governance structures are intended to help coordinate across community stakeholders and make better decisions. These dynamics are influenced by the issues covered in Dose of DeFi, but I believe they deserve their own focused analysis.
Govern This aims to educate token holders and make them better voters. Emphasis will be placed on specific governance proposals and relaying community governance discussions on forums and weekly calls.
Governance is a coordination technology that has helped countries and companies build more than the sum of their parts. Blockchains are also a coordination technology, but for computers, not humans***.*** Govern This will track the development of the melding of these two over the coming years.
Like governance, Govern This is a work in progress. I would appreciate any feedback on format, topics covered or any other suggestions to make the newsletter better. Just hit reply.
The first issue of Govern This is below. Please click here to subscribe.
Thanks for reading,

dxDAO aims to power DeFi protocols through decentralized governance
Gnosis launched a long-awaited DEX last week with batched auctions for low-liquidity trade pairs. The front-end, Mesa.Eth.Link is owned and operated by dxDAO, a decentralized collective that hopes to power other DeFi protocols.
While dYdX does not have any specific governance plans (yet), this tweet from dYdX founder Antonio Juliano is a common approach to governance.
📷Antonio Juliano @AntonioMJuliano3) 0x should focus less on governance in the short term. It’s way more important to first build something with a large amount of adoption that’s worth governing
December 6th 2018
3 Retweets62 Likes
The tweet at the end of 2018 was in response to 0x and its native token, ZRX. The project was popular but the token had no use case outside of governance.
This governance strategy – build now, decentralize later – is widely accepted in the space and is perhaps best exemplified by the A16Z’s Jesse Walden’s post, “Progressive Decentralization: A Playbook for Building Crypto Applications”, which the A16Z-backed Compound has essentially implemented (more in the section below).
dxDAO, on the other hand, maintains that decentralization must come at the beginning or else the core team and investors will have an outsized influence on the project in formal (token voting) or informal ways (dictators for life).
Background
dxDAO was launched in May 2019, spun out of a collaboration between Gnosis and DAOstack over managing the DutchX platform. dxDAO’s key governance design is separating financial rights to the DAO (DXD) from voting power over the DAO (Reputation). It used an Edgeware-style lock drop to distribute reputation to stakeholders in May of last year. Any user could lock up ETH or an accepted ERC-20 for a month and receive Reputation, which are voting rights in dxDAO, even though it is not a token and cannot be transferred.
Over 400 unique Ethereum addresses participated in the distribution scheme. Gnosis went through a pretty extensive process in July 2019 to “step back” from its involvement in the DAO, and since then, the community and dxDAO have aligned behind a mission of “putting the ‘De’ in Decentralized Finance”.
Following on last week’s launch of Mesa.ETH.Link, dxDAO is conducting a fundraiser or (“DAICO”?) to help fund its new slate of DeFi products, including a prediction market platform (Omen) and a privacy-centric DeFi dashboard (Mix).
Project launch is typically when a project is most centralized. Execution is hard and direction and accountability are important. dxDAO’s approach will be an interesting counterexample to the “decentralize later” trend and may provide insight into new governance strategies.
Click here for more information about the dxDAO fundraiser.
Here’s what is on the dxDAO docket this week:
Compound governance goes live, has it found Market-Protocol-Fit?
Since its founding in 2017, Compound has executed with an almost flawless record: no bugs/hacks, a major protocol upgrade and a big name fundraise (twice).
But all of that has been because Compound, the company, has executed well, but can protocol development and the growth of the platform be sustained with community management? We shall see.
Compound’s governance system could not be simpler. Anyone with at least 1% of COMP can submit a proposal of executable code. COMP holders have a 3 day voting period; the proposal passes with a majority of token votes AND a 4% quorum of all COMP tokens.
The 1% minimum for proposal submission is a good anti-Sybil mechanism but it greatly limits participation by small users. There is delegation, so you could imagine a “proposal petition” where you would delegate your COMP to a proposal instead of signing your name.
Compound is clearly taking the “less governance is the best governance” approach. This has worked surprisingly well with Bitcoin and Ethereum, which of course, do not have any formal governance, but those communities clearly have informal governance systems that make decisions.
The biggest governance question for Compound: who is the community?
Market-Protocol-Fit
Other Internet has an intriguing essay on the emergent order from new blockchain tokens and their communities. It is worth a read. It discusses the emergent iteration that blockchains – as a technology and a community – go through to find a niche, both in culture and product.
While it focuses on base-layer blockchains that launch with a token, the essay underscores the most underrated governance element: token distribution. It quotes an insightful tweet from Eric Wall
📷Eric Wall @ercwlA question that keeps me up at night: Is it possible to create a rubbish coin based on advanced bullshit, build a community of misguided fans nevertheless, run it centralized for 5 yrs, hardfork-copy the design of a real working project, keep the community and become a success?
keysheet @keysheet
@ErcWll was one of the first vocal critics of IOTA back in 2017, shortly before the project hit a market cap of $15B. https://t.co/2267e8LEpl Today, the project is down 99% and appears to be brutally falling apart. A thread:
February 13th 2020
17 Retweets163 Likes
Before Bitcoin could harden its code and find ‘Digital Gold’ and before Ethereum found ‘DeFi’ and ships ETH2.0, both needed to find a “a strong community of believers” in order to create a “virtuous cycle between headless brands and infrastructural build-out to progressively realize [their] initial promise.”
Communities are connected through a wide spread token distribution, Bitcoin through cypherpunks and online drugs and Ethereum through a global ICO (what Teo Leibowitz called “The Immaculate ICO”).
$COMP distribution
The biggest “news” has been details about $COMP distribution:
There are no explicit plans yet, but the widely held assumption is that the COMP distribution will be determined by the interest earned and paid by users on the protocol since its inception. This is a clever way that only incentivizes more use of the protocol and is hard to game because interests accrues over time.
But the question still remains, what will the COMP community look like and what values will it espouse? Can emergent cultures arise out of Silicon Valley too?
Here’s what is on the Compound docket this week:
Maker and wBTC, a test case for the MIP process
While Maker had planned to spend Q2 moving forward with their upgraded governance process, most of its focus has been on restoring the Dai peg.
For more on how the Maker governance process has expanded outside the core community, check out the previous edition of Govern This.
Here’s what is on the Maker docket this week:
Governance and Risk meeting (April 23)
Single Collateral Dai shutdown – the process has begun. A poll passed with May 12 as the official SCD shutdown. Just yesterday, an executive just passed yesterday to make the MKR oracle fee-less, which will help with migration. Many in the community think the migration of debt from SCD will do more than enough to restore the peg.
13 MIPs and 2 sub proposals – Core to the new Maker governance process is the “Maker Improvement Proposals (MIPs), which are modeled off of BIPs (for Bitcoin) and EIPs (for Ethereum). The two sub-proposals are to appoint the Smart Contracts Team and assign Charles St. Louis as the MIP editor.
The 13 MIPs are listed below:
- MIP1 (Maker Governance Paradigms)- MIP2 (Launch Period)- MIP3 (Governance Cycle)- MIP4 (MIP Amendment and Removal Process)- MIP5 (Emergency Voting System)- MIP6 (Collateral Onboarding Form/Forum Template)- MIP7 (Onboarding and Offboarding Domain Teams for Collateral Onboarding)- MIP8 (Domain Greenlight)- MIP9 (Community Greenlight)- MIP10 (Oracle Management)- MIP11 (Collateral Onboarding General Risk Model Management)- MIP12 (Collateral and Risk Parameter Management)
By and large, the MIPs codify many of the informal Maker governance processes. There is currently a request for comments period (MIP forum) and there will be an informal poll on Monday, April 27 on whether to proceed with the 13 MIPs and 2 sub proposals. If it’s a “Yes”, than an executive for an official ratification vote would start on May 1 and lasts for 4 days. If it passes, the official governance cycle will begin and the rest of the MIPs will likely be approved from May 4 – 6.
Other Governing Things
That’s it! Feedback definitely appreciated. Just hit reply. Written in Brooklyn where it rained all day. No euchre today, but yesterday was epic.

Announcing r/Avalanche_, a positive, well-moderated, community-run subreddit for open and cordial discussion of Avalanche (AVAX), whose mainnet launches on September 21st.

Avalanche_ is the name of the cryptocurrency subreddit I have launched, to give the community of people learning about Avalanche and Avalanche Enthusiasts a place to discuss Avalanche free from toxicity and negativity.
This is an "unofficial" subreddit, in the context of Avalanche this means it is not owned or controlled by AvaLabs, which is the developing force behind the Avalanche project.
I am already up past 80 members in just a few days of social networking with my peers. I have also written an article about the subreddit, its purpose and origin, and my moderation strategies and philosophies, that you may read if you'd like. This article is posted in the subreddit.

What is Avalanche?

Avalanche is a cryptocurrency based on Team Rocket's whitepaper "From Snowflake to Avalanche" developed by AvaLabs, which is headed by the computer scientist Emin Gün Sirer, his cofounders, and a large global team of developers, community managers, and marketing evangelists.
Avalanche is named after the Avalanche Protocol, which is a specific and new consensus algorithm detailed in the original whitepaper. In my own words, I would describe it as a gossip/pandemic algorithm for a third-generation blockchain, utilizing multiple rounds of locally-random peer sampling, polling, and pre-state consensus. Essentially, this allows for a very fast and efficient consensus algorithm with mathematically sound properties. Proof of Stake is used as the underlying anti-sybil mechanism.
Some properties that you may find interesting:
1) Anyone can run a node. On your laptop, on your rasberry pie, it will all work with very minimum hardware requirements that basically all household computers meet.
2) Even if everyone runs these lightweight nodes, the Avalanche network has proven to process over 4500 tps. This is without high-grade hardware and also without sharding.
3) Transaction finality is under a second, with few exceptions that never take longer than about three seconds. By transaction finality i mean there is a practical 0% chance your transaction will be reversed, equal to that of around 6 bitcoin confirmations.
4) All validating nodes take part in the block-production process, and basically anyone can become a validator. There is no distinction (that I know of) between validating as a full node and validating as a block producer. Both are just validating and can influence the network.
5) The minimum amount of AVAX you need to validate is 2000, but this is parameterized, which means that the validators periodically are able to vote onchain to incrementally change it. There are other parameterized constants including the expensiveness of transaction fees.
Avalanche (AVAX) is also a robust and versatile smart contract chain that is fully equipped with it own virtual machine as well as the Ethereum Virtual Machine. All Ethereum applications can be ported over to Avalanche with no developer downtime.
Avalanche (AVAX) also has this unique and interesting property of inherent cross-chain same-asset atomic swaps, allowing for the creation of subnetworks with custom virtual machines, custom economics, custom anti-sybil mechanisms, basically the full scope of a custom blockchain utilizing the Avalanche consensus engine, fully interoperable with Avalanche's default chains. You can launch a subnetwork that still uses the Avalanche token, or you can launch one with its own token, really the possibilities are super open-ended.
Avalanche (AVAX) also has this interesting architecture of being kind of like a hybrid between a blockchain and a DAG. This one is hard for me to explain, so I will explain what I do understand. Avalanche actually is made of three default blockchains/networks, all synergistically working together and supporting the same native AVAX token:
Finally, a characteristic of AVAX that I absolutely love is how deflationary it is. Its the most deflationary cryptocurrency I have ever heard of. It has a maximum supply cap like Bitcoin (720M is max), all fees are burned like in Ethereum's EIP-1559, and there is incentivized staking that is open to basically everybody. I say the staking is incentivized, because you need to stake and validate in order to run a subnetwork, which can offer rewards (or be a business goal).

What is Avalanche_?

Avalanche_ is the cryptocurrency subreddit I am launching which allows for clean and open discussion of Avalanche as well as other cryptocurrencies. This subreddit focuses primarily on offering a moderated space to discuss Avalanche, where personal attacks are not allowed. Freedom of belief in opinion is protected, but anything that hurts people or is damaging to the culture of openness and positivity is prohibited and moderated. 99% of all moderation is performed by the moderator, and the other 1% is done by me and anyone else who may later be added to the team.
If you are wondering "Okay but why you?" I cannot give an adequate response besides "Because I care". I would point out that out of the 3000+ people participating in "Avalanche Hub" (which is AvaLabs' official incentivized community participation and marketing platform) i am #5 in terms of influence and my community contributions, but I suppose this is a bit anecdotal. I have written many articles in support of AVAX though, and this is a bit more material. I may share them below.
I have gotten a bit sophisticated with the automoderator tool, and I have done this because I want to protect noobs from toxicity and fighting. Essentially what I have done is 5 things, and together its created a toxicity neutralizing mechanism thats held up so far:
1) An initial vetting process that requires all accounts to have positive comment karma and be a week old, have 50 post karma, or 25 comment karma. This is a relaxed anti-spam measure. Currently parts of this are turned off, but they will be re-enabled in a few days. I did not make this measure too stringent because I want it to be easy for noobs to join and participate.
2) A well researched and extensive blacklist of indisputably toxic words, phrases, and domains that trigger instant removal.
3) A well researched and extensive greylist of fairly toxic words, phrases, and domains that trigger removal if the poster lacks a certain amount of post karma, comment karma, age, or goes reported.
4) A hierarchical and tiered report threshold where non-greylisted comments get removed on X number of reports, based on both post karma and comment karma. The lesser of these two make the weakest link.
5) An anti-doxxing protection algorithm which protects against credit cards, phone numbers, emails, and more from being doxxed. I myself have not created this, but I have been modifying it to fit the group.
I probably will not have to do much of any manual moderation aside from updating automoderator to keep it up to date with the lingo of people with bad intentions. However I am on Reddit everyday and I will be here to protect people from community attackers if its ever needed.
It is my belief that culture is absolutely crucial to the health of a project, and for this reason I am using both automated moderation and community moderation to curtail outsider attacks and infighting alike. As soon as the subreddit becomes a bit more active, it will make it easier for me to ask around the community for moderators.

Welcome to Avalanche

All are welcome in the Avalanche community. All I ask is that you don't intentionally and maliciously try to make others feel unwelcome. Avalanche is a global, decentralized, cryptocurrency and open source software for all to build on and utilize.
I am not a gatekeeper, but a mere member of the community which seeks to provide a positive and friendly platform for redditors to social network on. Links to relevant and official Avalanche community resources are in the "About" section of Avalanche_.
I hope to see many of you there! Let's change the world with this new, globally-scalable, deflationary, interoperable technology.
Build The Internet of Finance.

Want to know why NEM should be as popular as Ethereum? this will be bigger than any altcoins you see, here's why

Want to know why NEM should be as popular as Ethereum? this will be bigger than any altcoins you see, here's why

Altcoin Explorer: NEM (XEM), the Enterprise-Grade Blockchain Platform


https://preview.redd.it/5ogfihikwkg51.png?width=1300&format=png&auto=webp&s=099780e02777d16d4e2add64b249c46da1cd488b
Nestled among the top 40 cryptocurrencies by reported market cap, New Economy Movement — popularly known as NEM (XEM) – is a peer-to-peer (P2P), dual-layer blockchain smart contract platform written in one of the most influential programming languages, Java. NEM uses the proof-of-importance (POI) consensus algorithm that essentially values the tokens held and the activity conducted by the nodes on the blockchain network.
In this Altcoin Explorer, BTCManager delves deeper into the finer intricacies of the NEM blockchain protocol, including the project’s POI consensus algorithm, its native digital token XEM, and some of its real-world use-cases.
Without further ado, let’s get to the core of this high-performance distributed ledger technology (DLT) platform.

History of NEM

NEM was launched on March 31, 2015, with an aim to develop an enterprise-grade blockchain protocol that could circumvent the infamous trilemma of blockchain: scalability, speed, and privacy.
Operated by a Gibraltar-registered NEM Group, NEM is a fork-out version of the NXT blockchain. After the successful fork, the NEM community decided to build its ecosystem from the ground up and developed its own codebase to make the network more scalable and faster.
NEM’s insistence toward building its own tech infrastructure led to a DLT protocol that is unlike anything resembling other similar platforms.
Today, NEM ranks among the top go-to blockchain platforms for enterprises across the world, rivaling competing protocols including Ethereum (ETH), and TRON (TRX), among others.

NEM’s Proof-of-Importance (POI) Algorithm

Unlike Bitcoin’s (BTC) energy-intensive Proof-of-Work (PoW) and Ethereum’s yet-to-be-implemented Proof-of-Stake (PoS) consensus algorithm, NEM uses PoI consensus mechanism.
The PoI mechanism achieves consensus by incentivizing active user participation in the NEM network. This consensus infrastructure ensures an agile decentralized network by rewarding well-behaved nodes that not only possess a significant stake in the network but are also actively engaged in executing transactions to maintain the network’s robustness.
Specifically, each node in the network possesses an ‘Importance Score’ that impacts the number of times the said node can ‘Harvest’ the XEM altcoin.
Initially, when a user puts XEM tokens into their wallet, they are called ‘unvested coins.’ Over time, as the wallets start accumulating an increasing number of XEM and contribute to the network’s transaction volume, they start collecting importance scores. At the same time, the XEM tokens in these wallets change into ‘vested coins,’ provided that there are at least 10000 tokens in the wallet.
To put things into perspective, let’s take the help of a small example.
On day 1, Joe receives 50,000 XEM in his digital wallet. Now, with each passing day, the NEM network will ‘vest’ 10 percent of the tokens held by Joe. So, on day 2, 5,000 tokens held by Joe are vested into the network. On day 3, 10 percent of the remaining tokens – 15,000 XEM – get vested into the network, leaving Joe with 13,500 XEM, and so one. After a couple of days, Joe sees that the number of XEM vested by him has crossed the 10,000 coins threshold, thereby, making him eligible to seek rewards from the NEM blockchain for his contribution to vesting his tokens.
Close followers of blockchain projects would find the aforementioned network reward mechanism bear a close resemblance to the PoS consensus algorithm. However, it’s worthy of note that vesting coins is just one way of calculating a node’s importance score.
The NEM protocol also rewards nodes that are responsible for most activity on the network. In essence, this means that the higher the number of transactions executed by a node, the more likely it is to gain higher importance points. The balance between vesting XEM and network activity is an important metric to be maintained by NEM nodes as it directly impacts their likelihood of harvesting XEM.
NEM’s consensus algorithm does away with several issues plaguing the more energy-intensive protocols such as PoW. For instance, PoI does not necessarily require high-energy hardware to run the nodes. The decentralized nature of the algorithm means that almost any machine — irrespective of its tech configuration – can participate in the NEM ecosystem ensuring it remains decentralized.

NEM’s Native Digital Token — XEM

XEM, unlike the vast majority of other cryptocurrencies, isn’t mined or staked using Pow or PoS algorithms. Rather, as explained earlier, XEM is ‘harvested’ through the PoI algorithm which ensures a steady supply of the digital token without flooding the market and involving the risk of a dramatic crash in price.
Per data on CoinMarketCap, at the time of writing, XEM trades at $0.04 with a market cap of more than $382 million and a 24-hour trading volume of approximately $6.8 million. The coin reached its all-time high of $1.92 in January 2018.
A large number of reputable cryptocurrency exchanges trade XEM, including Binance, Upbit, OKEx, Bithumb, ProBit, among others. The digital token can be easily traded with BTC, ETH, and USDT trading pairs.
That said, if you wish to vest your XEM to partake in the maintenance of the NEM network and earn rewards, it is recommended you store your tokens in the official NEM Nano wallet for desktop and mobile OS. Only XEM tokens held in the official NEM Nano wallet are eligible for vesting.

NEM Use-Cases

To date, NEM has been deployed for various real-world applications with promising results.
In 2018, Ukraine launched a blockchain-based e-voting trial leveraging the NEM DLT platform.
At the time, Ukraine’s Central Election Commission – with the local NEM Foundation representation – estimated the test vote trial in each polling station could cost as low as $1,227. The organization’s Oleksandr Stelmakh lauded the efforts, saying that using a blockchain-powered voting mechanism would make it impossible for anyone to fiddle with the records. The Commission added that the NEM protocol presents information in a more user-friendly format for voters.
In the same year, Malaysia’s Ministry of Education launched an e-scroll system based on the NEM blockchain to tackle the menace of fake degrees. The University Degree Issuance and Verification System use the NEM blockchain which is interrogated upon scanning of a QR code printed on the degree certificate.
The Ministry added that one of the primary reasons for its decision to selected the NEM platform was its unique and cutting-edge features in managing traceability and authentication requirements.
On a recent note, the Bank of Lithuania announced that it would be issuing its NEM blockchain-powered digital collector’s coin (LBCoin) in July after the successful completion of its testing phase.

Final Thoughts

Summing up, NEM offers a wide array of in-house features that separate it from other blockchain projects in a space that is becoming increasingly congested. NEM’s creative PoI consensus algorithm is a fresh take on the PoS algorithm for performance enhancement. Further, the project’s newly launched enterprise-grade DLT solution, Symbol, offers a tremendous option to businesses to help them cut costs, reduce complexities, and streamline innovation.
NEM uses the Java programming language that makes it an easy project for developers to get involved with, unlike other projects such as Ethereum that use platform-specific programming languages like Solidity. The project’s tech infrastructure not only makes it less power-intensive compared to Bitcoin but also more scalable than its rival projects including Ethereum and NEO.
NEM’s tagline, “Smart Asset Blockchain, Built for Performance,” perfectly captures everything the project has to offer. Over the years, NEM’s active developer community has craftily addressed the notorious bottlenecks in the vast majority of blockchain solutions, The future looks promising for NEM as it continues to foster a trustless and blockchain-driven economy for tomorrow.

Please STOP messing with the economy and REVERT the 2 most recent changes.

I've been pretty quiet on all the controversies and changes. I can't anymore. These new changes are NOT FUN.
Played a couple of months on the previous wipe. Learned what to do, what to get, where good places to go are, where not to go, etc.
Started fresh on this wipe. OKAY, now here we go boyz. We know what to do! Keep X, Y, and Z, sell the rest. Craft Mag Boxes, Wires, and Salewa. Prioritize certain areas, avoid others. Should be a smooth launch and we'll be able to do well.
---------------------------
We'll make some money on the flea market!
NOPE.............let's increase taxes on the market until selling high demand items actually COSTS you money.
Dfuel at market price actually COSTS you money to sell it. 110% TAX
Empty Fuel cans at market price takes HALF of your profit 50% TAX
If you want to reduce the prices of items...........INCREASE the supply (aka spawn rate). Economics 101. I learned that even before I got to college.
---------------------------
Well we still know what traders to sell to!
NOPE.........let's mess with all the prices so that valuable things aren't worth picking up anymore and it takes tons of time to find out which trader to sell to.
NERF the crap out of Bitcoin prices. SO SORRY to the people who PAID to have full bitcoin farms. I couldn't afford it, but I feel your pain. Millions or rubbles that won't pay off for months from now.
NERF Mag Box prices. SO SORRY to the people who actually bought a scav junkbox and filled it with empty fuel containers and metal scissors. I did this, and it effectively wiped out all profit from doing it. I'm dumping all of it on the market now, I suggest you do the same.
If you're going to make radical economic changes like this, do it at the BEGINNING of a wipe, and let everyone know it's DIFFERENT. Make it simple so people can figure it out.
FYI there are around 100 videos out there that say sell to Therapist, then Skier, then Mechanic, then Prapor, then Fence..............which was really EASY to remember. Now 100% of those videos are all BAD INFO for your new players.
--------------------------
You want to combat RMT? Sure, great.........go BAN THE PEOPLE WHO BUY RUBLES. Advertise that it's a bannable offense on the MAIN MENU. Hell even put a counter up there on how many ruble buyers have been banned. PROBLEM SOLVED.
People want to raid, they want to have fun, they want to get good loot and sell it QUICKLY and get back into raid. Spending endless amounts of time trying to figure out if they should Flea Market (without getting screwed on taxes), or Vendor (and who to vendor it to) is NOT FUN.
STOP messing with the Flea Market and Traders! Revert the Taxes and Trader Buy Prices!

Want to stop receiving tons of hate?
It's fairly easy.
IN GAME POLLING
When the game launches or heck even on the launcher........there's an optional poll for people to take on changes. Make sure it's VERY noticeable.
75%+ of players like an idea, go ahead and implement.
50% of players like an idea............maybe wait or refine it more.
25% or less of players like an idea...............no, no, no. Whew dodged a bullet there!

STOP relying 100% on reddit and the forums for feedback. LESS THAN 10% OF YOUR PLAYER BASE VISITS REDDIT OR THE FORUMS. Imagine if only 10% of a country could vote on things.........you'd get some terrible and awful things that get passed into law.

You'll get a LOT better results with in game polling (since ALL of your players will see it). One of the biggest downfalls of developers is thinking "oh I know what the players want" (unless you're a mind reader, nope) or "we need to keep our vision of the game pure" (if nobody likes your vision, it doesn't matter what your vision is AT ALL).

Want to know why NEM should be as popular as Ethereum? this will be bigger than any altcoins you see, here's why

Want to know why NEM should be as popular as Ethereum? this will be bigger than any altcoins you see, here's why

Altcoin Explorer: NEM (XEM), the Enterprise-Grade Blockchain Platform


https://preview.redd.it/manbawoqvkg51.png?width=1300&format=png&auto=webp&s=fcbae1f067261326f11641bb9b18cd6f57616966
Nestled among the top 40 cryptocurrencies by reported market cap, New Economy Movement — popularly known as NEM (XEM) – is a peer-to-peer (P2P), dual-layer blockchain smart contract platform written in one of the most influential programming languages, Java. NEM uses the proof-of-importance (POI) consensus algorithm that essentially values the tokens held and the activity conducted by the nodes on the blockchain network.
In this Altcoin Explorer, BTCManager delves deeper into the finer intricacies of the NEM blockchain protocol, including the project’s POI consensus algorithm, its native digital token XEM, and some of its real-world use-cases.
Without further ado, let’s get to the core of this high-performance distributed ledger technology (DLT) platform.

History of NEM

NEM was launched on March 31, 2015, with an aim to develop an enterprise-grade blockchain protocol that could circumvent the infamous trilemma of blockchain: scalability, speed, and privacy.
Operated by a Gibraltar-registered NEM Group, NEM is a fork-out version of the NXT blockchain. After the successful fork, the NEM community decided to build its ecosystem from the ground up and developed its own codebase to make the network more scalable and faster.
NEM’s insistence toward building its own tech infrastructure led to a DLT protocol that is unlike anything resembling other similar platforms.
Today, NEM ranks among the top go-to blockchain platforms for enterprises across the world, rivaling competing protocols including Ethereum (ETH), and TRON (TRX), among others.

NEM’s Proof-of-Importance (POI) Algorithm

Unlike Bitcoin’s (BTC) energy-intensive Proof-of-Work (PoW) and Ethereum’s yet-to-be-implemented Proof-of-Stake (PoS) consensus algorithm, NEM uses PoI consensus mechanism.
The PoI mechanism achieves consensus by incentivizing active user participation in the NEM network. This consensus infrastructure ensures an agile decentralized network by rewarding well-behaved nodes that not only possess a significant stake in the network but are also actively engaged in executing transactions to maintain the network’s robustness.

So, on day 2, 5,000 tokens held by Joe are vested into the network. On day 3, 10 percent of the remaining tokens – 15,000 XEM – get vested into the network, leaving Joe with 13,500 XEM, and so one. After a couple of days, Joe sees that the number of XEM vested by him has crossed the 10,000 coins threshold, thereby, making him eligible to seek rewards from the NEM blockchain for his contribution to vesting his tokens.
Close followers of blockchain projects would find the aforementioned network reward mechanism bear a close resemblance to the PoS consensus algorithm. However, it’s worthy of note that vesting coins is just one way of calculating a node’s importance score.

Community Points FAQ - English

Important note:
The beta of the Community Points program is on the Rinkeby network. If you do not know what that means - do not remove your Reddit community points tokens from your Reddit Vault by trying to integrate any other Ethereum wallets, or by sending them to smart contracts.
What are Community Points
Community points are a new initiative by Reddit. They are points that represent ownership in a subreddit.
Each community will get their own community points that they get to name and design.
Where are Community Points stored?
Community Points are a type of "Ethereum" "token" that is stored on a "blockchain" - just like Bitcoin!
This means that once you earn the tokens you own them.
You can store them in your "Reddit Vault" or a traditional Ethereum wallet.
How many Community Points are there?
There are a total of 250M of each type of community point.
So the /Cryptocurrency subreddit will have a max of 250M "$MOON" tokens, but, another subreddit will have a maximum of 250M of their own token.
Are all 250M tokens / points released right away?
No. To start there will be only 50M of each token. These will be awarded to users based on the posts they've previously made in the subreddit.
The other 250M tokens will slowly be awarded on a monthly basis.
Is the amount awarded each month the same?
No. The amount of tokens awarded will get smaller each month, this will last until the 250M tokens have been created. The estimated date for that is sometime in 2050.
How do I earn Community Points / Tokens?
You'll earn the tokens based on your contributions to the subreddit.
When you make a post or a comment that gets upvoted, you'll earn a portion of the tokens that get distributed by the system that week.
Other users can also "tip" you. This means they will give you some of the tokens they've earned.
What can I use Community Points / Tokens for?
You can use the tokens to buy "Special Memberships" for each individual subreddit.
These memberships give you special features on the subreddit. These include:
How Much Does the Special Membership Cost?
The "Special Membership" for a subreddit will vary in cost between different tokens.
On the /Cryptocurrency subreddit the membership costs 1000 MOONS per month.
What Happens to the Community Points / Tokens I use for the Special Membership?
When you use your tokens for the "Special Membership" those tokens will be "burned" - which is cryptocurrency slang for destroyed.
This means there will always be less than 250M tokens as they will continue to be used overtime.
Can I use Community Points / Tokens for anything else?
Yes.
You'll also be able to use the tokens you've earned to vote in weighted polls, or to send a tip to other users.
Finally, because it is an ERC-20 Ethereum token, you can transfer it to other websites and integrate it into other products. This allows you to buy, sell, trade and use the token anywhere you want.
What is the Reddit Vault?
The "Reddit Vault" is a special section of Reddit's mobile app that allows you to connect to an Ethereum powered wallet. In this section you'll be able to claim your tokens, see your token balances, and redeem the tokens.
Your Reddit Vault sometimes may also be called a "wallet" as this is the common terminology in the blockchain industry.
How do I create a Reddit Vault?
You can create your Reddit Vault in the Reddit app on iOS and Android.
You'll click on your profile and select "Vault" and it will guide you through the steps.
If you need more detailed instructions you can checkout the detailed instructions
Do I have to use Reddit Vault as my wallet?
No. You do not have to use Reddit Vault as your wallet - but this does allow you the feature of backing up your wallet to Reddit.
If you want to use a different Ethereum wallet such as MetaMask or Brave Browser, you can import your 'seed phrase' from the creation of that wallet.
This is only recommended for experienced cryptocurrency users.
You can find the instructions to import your existing wallet into your Reddit Vault here
If I create a wallet using Reddit Vault can I use that wallet elsewhere?
Yes.
If you are creating your first cryptocurrency wallet by using Reddit Vault, you may want to import that wallet into a different software such as MetaMask or 'Brave Browser'.
You can follow these instructions:
Make sure you set your MetaMask wallet or Brave Browser Wallet to use the Rinkeby test network.
What is the "Seed Phrase"?
A seed phrase is a set of 12 random words that wallet software use to help generate our "public key" and "private key" that make up your wallet.
The seed phrase is the only way to recover a cryptocurrency wallet if you lose our private key.
Where should I store my seed phrase?
Your seed phrase should be stored in a secure location. Ideally you should not keep the seed phrase in a picture (on your phone) or in a downloaded file or digital notepad.
It's best to write down your seed phrase, or to use a password manager such as LastPass to store it securely.
If I lose my seed phrase, can Reddit get my community points back?
No.
If you lose your seed phrase and do not have your private key then no one can help you to recover your wallet or your tokens. They are lost forever.
Can I lose points from my balance?
No.
Once you have claimed you have claimed your points the are in your wallet on the Ethereum blockchain. No one can take those points away from you. Not even Reddit staff.
You will not lose points for downvotes on your comments or on your posts. You will only learn a smaller percentage of tokens in the next week's distribution.
What is a public key?
Your public key (also sometimes called your "wallet address") is your address on the blockchain. It is similar to a postal address in that it unique identifies you and allows people to send you blockchain transactions, similar to how someone might send mail to your home address.
Just like a home address, the information isn't private, but, it is sensitive. You probably don't want everyone to have the address.
Your public key will be a long sting of numbers and letters but on Ethereum it will always start with "0x"
What is a private key?
A private key is like your password. It is private information that must be kept secure.
You cannot ever change your private key. So if it gets compromised even once you will need to make a new wallet.
Never share your private key with anyone. Ever.
Will Reddit staff ever need to know my seed phrase or my private key?
No. Never.
Can I buy/sell Community Points / Tokens?
There are no exchanges for these tokens as the are currently on the Rinkeby test network.

Foreword
The consensus mechanism is one of the important elements of the blockchain and the core rule of the normal operation of the distributed ledger. It is mainly used to solve the trust problem between people and determine who is responsible for generating new blocks and maintaining the effective unification of the system in the blockchain system. Thus, it has become an everlasting research hot topic in blockchain.
This article starts with the concept and role of the consensus mechanism. First, it enables the reader to have a preliminary understanding of the consensus mechanism as a whole; then starting with the two armies and the Byzantine general problem, the evolution of the consensus mechanism is introduced in the order of the time when the consensus mechanism is proposed; Then, it briefly introduces the current mainstream consensus mechanism from three aspects of concept, working principle and representative project, and compares the advantages and disadvantages of the mainstream consensus mechanism; finally, it gives suggestions on how to choose a consensus mechanism for blockchain projects and pointed out the possibility of the future development of the consensus mechanism.

Source: Hasib Anwar, "Consensus Algorithms: The Root Of The Blockchain Technology"
The picture above shows 14 relatively mainstream consensus mechanisms summarized by a geek Hasib Anwar, including PoW (Proof of Work), PoS (Proof of Stake), DPoS (Delegated Proof of Stake), LPoS (Lease Proof of Stake), PoET ( Proof of Elapsed Time), PBFT (Practical Byzantine Fault Tolerance), SBFT (Simple Byzantine Fault Tolerance), DBFT (Delegated Byzantine Fault Tolerance), DAG (Directed Acyclic Graph), Proof-of-Activity (Proof of Activity), Proof-of- Importance (Proof of Importance), Proof-of-Capacity (Proof of Capacity), Proof-of-Burn ( Proof of Burn), Proof-of-Weight (Proof of Weight).
Next, we will mainly introduce and analyze the top ten consensus mechanisms of the current blockchain.
》POW
-Concept:
Work proof mechanism. That is, the proof of work means that it takes a certain amount of computer time to confirm the work.
-Principle:
Figure 7 PoW work proof principle
📷
https://preview.redd.it/xupacdfc4db51.png?width=554&format=png&auto=webp&s=3b6994641f5890804d93dfed9ecfd29308c8e0cc
The PoW represented by Bitcoin uses the SHA-256 algorithm function, which is a 256-bit hash algorithm in the password hash function family:
Proof of work output = SHA256 (SHA256 (block header));
if (output of proof of work if (output of proof of work >= target value), change the random number, recursive i logic, continue to compare with the target value.
New difficulty value = old difficulty value* (time spent by last 2016 blocks /20160 minutes)
Target value = maximum target value / difficulty value
The maximum target value is a fixed number. If the last 2016 blocks took less than 20160 minutes, then this coefficient will be small, and the target value will be adjusted bigger, if not, the target value will be adjusted smaller. Bitcoin mining difficulty and block generation speed will be inversely proportional to the appropriate adjustment of block generation speed.
-Representative applications: BTC, etc.
》POS
-Concept:
Proof of stake. That is, a mechanism for reaching consensus based on the holding currency. The longer the currency is held, the greater the probability of getting a reward.
-Principle:
PoS implementation algorithm formula: hash(block_header) = Coin age calculation formula: coinage = number of coins * remaining usage time of coins
Among them, coinage means coin age, which means that the older the coin age, the easier it is to get answers. The calculation of the coin age is obtained by multiplying the coins owned by the miner by the remaining usage time of each coin, which also means that the more coins you have, the easier it is to get answers. In this way, pos solves the problem of wasting resources in pow, and miners cannot own 51% coins from the entire network, so it also solves the problem of 51% attacks.
-Representative applications: ETH, etc.
》DPoS
-Concept:
Delegated proof of stake. That is, currency holding investors select super nodes by voting to operate the entire network , similar to the people's congress system.
-Principle:
The DPOS algorithm is divided into two parts. Elect a group of block producers and schedule production.
Election: Only permanent nodes with the right to be elected can be elected, and ultimately only the top N witnesses can be elected. These N individuals must obtain more than 50% of the votes to be successfully elected. In addition, this list will be re-elected at regular intervals.
Scheduled production: Under normal circumstances, block producers take turns to generate a block every 3 seconds. Assuming that no producer misses his order, then the chain they produce is bound to be the longest chain. When a witness produces a block, a block needs to be generated every 2s. If the specified time is exceeded, the current witness will lose the right to produce and the right will be transferred to the next witness. Then the witness is not only unpaid, but also may lose his identity.
-Representative applications: EOS, etc.
》DPoW
-Concept:
Delayed proof of work. A new-generation consensus mechanism based on PoB and DPoS. Miners use their own computing power, through the hash algorithm, and finally prove their work, get the corresponding wood, wood is not tradable. After the wood has accumulated to a certain amount, you can go to the burning site to burn the wood. This can achieve a balance between computing power and mining rights.
-Principle:
In the DPoW-based blockchain, miners are no longer rewarded tokens, but "wood" that can be burned, burning wood. Miners use their own computing power, through the hash algorithm, and finally prove their work, get the corresponding wood, wood is not tradable. After the wood has accumulated to a certain amount, you can go to the burning site to burn the wood. Through a set of algorithms, people who burn more wood or BP or a group of BP can obtain the right to generate blocks in the next event segment, and get rewards (tokens) after successful block generation. Since more than one person may burn wood in a time period, the probability of producing blocks in the next time period is determined by the amount of wood burned by oneself. The more it is burned, the higher the probability of obtaining block rights in the next period.
Two node types: notary node and normal node.
The 64 notary nodes are elected by the stakeholders of the dPoW blockchain, and the notarized confirmed blocks can be added from the dPoW blockchain to the attached PoW blockchain. Once a block is added, the hash value of the block will be added to the Bitcoin transaction signed by 33 notary nodes, and a hash will be created to the dPow block record of the Bitcoin blockchain. This record has been notarized by most notary nodes in the network. In order to avoid wars on mining between notary nodes, and thereby reduce the efficiency of the network, Komodo designed a mining method that uses a polling mechanism. This method has two operating modes. In the "No Notary" (No Notary) mode, all network nodes can participate in mining, which is similar to the traditional PoW consensus mechanism. In the "Notaries Active" mode, network notaries use a significantly reduced network difficulty rate to mine. In the "Notary Public Activation" mode, each notary public is allowed to mine a block with its current difficulty, while other notary public nodes must use 10 times the difficulty of mining, and all normal nodes use 100 times the difficulty of the notary public node.

-Representative applications: CelesOS, Komodo, etc.
CelesOS Research Institute丨DPoW consensus mechanism-combustible mining and voting
》PBFT
-Concept:
Practical Byzantine fault tolerance algorithm. That is, the complexity of the algorithm is reduced from exponential to polynomial level, making the Byzantine fault-tolerant algorithm feasible in practical system applications.
-Principle:
Figure 9 PBFT algorithm principle
📷
https://preview.redd.it/8as7rgre4db51.png?width=567&format=png&auto=webp&s=372be730af428f991375146efedd5315926af1ca
First, the client sends a request to the master node to call the service operation, and then the master node broadcasts other copies of the request. All copies execute the request and send the result back to the client. The client needs to wait for f+1 different replica nodes to return the same result as the final result of the entire operation.
Two qualifications: 1. All nodes must be deterministic. That is to say, the results of the operation must be the same under the same conditions and parameters. 2. All nodes must start from the same status. Under these two limited qualifications, even if there are failed replica nodes, the PBFT algorithm agrees on the total order of execution of all non-failed replica nodes, thereby ensuring security.
-Representative applications: Tendermint Consensus, etc.

07-07 21:45 - 'Mass adoption: blockchain as a norm of modern life' (self.Bitcoin) by /u/CoinjoyAssistant removed from /r/Bitcoin within 381-391min

'''
It took a whole decade for the economy and business to understand blockchain technology, its strengths, and weaknesses. Several years ago, the first mature options for its practical application began to appear on the market.
[According to]1 Joseph Lubin, the founder and CEO of the blockchain company ConsenSys, the economic crisis caused by the coronavirus infection pandemic could be a watershed for blockchain technology.
Joseph Lubin and Mike Novogratz, the CEO of Galaxy Digital cryptocurrency bank, discussed the development prospects of the industry and the impact of the pandemic on the cryptocurrency business. Both entrepreneurs believe that the socio-economic crisis is driving industry growth.

Blockchain for Voting

Participation in online voting makes it possible not to visit polling stations, thereby not only to save time but also to minimize contacts during the pandemic.
Blockchain e-voting system undoubtedly fights against intruders and excludes the possibility of voting several times, since it stores unchangeable records of all votes and all identification data.
The blockchain e-voting results [are transparent]2 , cannot be changed, and can be accessed instantly. Blockchain for voting is not only more reliable, but also faster, eliminates the human factor, and allows you to instantly receive election results.

Blockchain in Logistics

Blockchain technology in logistics will greatly simplify business. Now, to send one typical sea cargo, it is required to have 240 copies of 36 original documents. [Komgo]3 , the consortium of traders, banks, and inspection firms, uses the DLT platform in order to get rid of this paper swamp, optimizing the process of cargo registration on the principle of “Know Your Customer”.
Parties can immediately receive confirmation that they have exact copies of the same data at their disposal, which speeds up the process and avoids legal disputes and conflicts.

Tuna Blockchain

The World Wide Fund for Nature (WWF) in Australia, Fiji and New Zealand has [launched]4 a pilot project in the Pacific Islands that will use blockchain technology to track tuna paths from “bait to plate”.
The project aims to stop illegal and unregulated fishing, as well as to stop human rights violations in the industry, including corruption schemes, illegal trade, and the use of slave labor in the fishery.

Blockchain Stamps

Lamborghini decided to digitize its collection postage stamps and [issued]5 the first blockchain-based stamp. This technology should guarantee the uniqueness and authenticity of each stamp.
In 2019 Austrian Post Office [launched]6 a line of [blockchain]7 authenticated stamps with 5 images of a unicorn. On those stamps, one could find credentials for the authentication on the Ethereum blockchain. In 2020, they kept on with last-year success and [announced]8 a new line with animal designs. As every crypto stamp has a private key, being also an Ethereum wallet, one can use them both a real stamp or as an alternative paper wallet with a nice visual style.

Blockchain Telemedicine

Recently, many medical blockchain projects have been created. One of them is [My Clinic]9 .
It’s a platform for instant communication with a personal doctor. It is based on a blockchain for exchanging client data, which allows patients to contact a new doctor without the need for a personal visit for an initial examination and transfer of medical documents. Consulting a doctor becomes easier when traveling, taking tests, and undergoing large-scale diagnostics.

The Future of Technology

Blockchain is likely to transform entire industries and, possibly, the entire economy through integration with other technologies.
The distributed nature of blockchain provides a valuable opportunity to conduct transactions cheaper and faster. Instead of “transferring” copies of documents between lawyers and banks and waiting for each stage of registration to be processed, blockchain gives all parties a complete overview of the procedure for the simultaneous implementation of several stages of the process.
For example, a consortium of law firms has teamed up with blockchain service providers [Proxeus]10 and [IBM]11 to reduce the time for setting up a commercial company from a few weeks to a few days. The first company to have made it [Drakkensberg]12 , was generally founded within two hours.

Resume

Thus, we see that blockchain technology has a wide range of implementations in the near future. And, perhaps, the one who starts it first will be ahead of competitors.

[ Bitcoin ] Mass adoption: blockchain as a norm of modern life

[ 🔴 DELETED 🔴 ] Topic originally posted in Bitcoin by CoinjoyAssistant [link]
It took a whole decade for the economy and business to understand blockchain technology, its strengths, and weaknesses. Several years ago, the first mature options for its practical application began to appear on the market.
According to Joseph Lubin, the founder and CEO of the blockchain company ConsenSys, the economic crisis caused by the coronavirus infection pandemic could be a watershed for blockchain technology.
Joseph Lubin and Mike Novogratz, the CEO of Galaxy Digital cryptocurrency bank, discussed the development prospects of the industry and the impact of the pandemic on the cryptocurrency business. Both entrepreneurs believe that the socio-economic crisis is driving industry growth.

Blockchain for Voting

Participation in online voting makes it possible not to visit polling stations, thereby not only to save time but also to minimize contacts during the pandemic.
Blockchain e-voting system undoubtedly fights against intruders and excludes the possibility of voting several times, since it stores unchangeable records of all votes and all identification data.
The blockchain e-voting results are transparent, cannot be changed, and can be accessed instantly. Blockchain for voting is not only more reliable, but also faster, eliminates the human factor, and allows you to instantly receive election results.

Blockchain in Logistics

Blockchain technology in logistics will greatly simplify business. Now, to send one typical sea cargo, it is required to have 240 copies of 36 original documents. Komgo, the consortium of traders, banks, and inspection firms, uses the DLT platform in order to get rid of this paper swamp, optimizing the process of cargo registration on the principle of “Know Your Customer”.
Parties can immediately receive confirmation that they have exact copies of the same data at their disposal, which speeds up the process and avoids legal disputes and conflicts.

Tuna Blockchain

The World Wide Fund for Nature (WWF) in Australia, Fiji and New Zealand has launched a pilot project in the Pacific Islands that will use blockchain technology to track tuna paths from “bait to plate”.
The project aims to stop illegal and unregulated fishing, as well as to stop human rights violations in the industry, including corruption schemes, illegal trade, and the use of slave labor in the fishery.

Blockchain Stamps

Lamborghini decided to digitize its collection postage stamps and issued the first blockchain-based stamp. This technology should guarantee the uniqueness and authenticity of each stamp.
In 2019 Austrian Post Office launched a line of blockchain authenticated stamps with 5 images of a unicorn. On those stamps, one could find credentials for the authentication on the Ethereum blockchain. In 2020, they kept on with last-year success and announced a new line with animal designs. As every crypto stamp has a private key, being also an Ethereum wallet, one can use them both a real stamp or as an alternative paper wallet with a nice visual style.

Blockchain Telemedicine

Recently, many medical blockchain projects have been created. One of them is My Clinic.
It’s a platform for instant communication with a personal doctor. It is based on a blockchain for exchanging client data, which allows patients to contact a new doctor without the need for a personal visit for an initial examination and transfer of medical documents. Consulting a doctor becomes easier when traveling, taking tests, and undergoing large-scale diagnostics.

The Future of Technology

Blockchain is likely to transform entire industries and, possibly, the entire economy through integration with other technologies.
The distributed nature of blockchain provides a valuable opportunity to conduct transactions cheaper and faster. Instead of “transferring” copies of documents between lawyers and banks and waiting for each stage of registration to be processed, blockchain gives all parties a complete overview of the procedure for the simultaneous implementation of several stages of the process.
For example, a consortium of law firms has teamed up with blockchain service providers Proxeus and IBM to reduce the time for setting up a commercial company from a few weeks to a few days. The first company to have made it Drakkensberg, was generally founded within two hours.

Resume

Thus, we see that blockchain technology has a wide range of implementations in the near future. And, perhaps, the one who starts it first will be ahead of competitors.

Accessibility – The use of blockchain-based voting apps allows people to cast their vote wherever they are in the world.

This could help to increase voter registration across many demographics ... Blockchain voting is similar to analogue voting that we’re used to. The same concepts and processes apply. In order to cast a digital vote, a citizen would need to register and prove their citizenship in a given jurisdiction. We could then record that identity and citizenship on the blockchain associated with that user’s key.
