In the most significant #blockchain upgrade in history, the #Ethereum network is moving from a #proofofwork (#PoW) to a #proofofstake (#PoS) consensus mechanism to confirm transaction blocks, known as “The Merge”

Read more and debunk myths: bit.ly/3uQ4RZg
1/ The two major upgrades, PoS #consensus and #sharding, promise to deliver fast transaction times with low network costs without sacrificing scalability, security, or decentralization. #TheMerge is Phase 0 of the rollout of the Ethereum 2.0 improvements this year. Image
2/ ‘The Merge’ will replace PoW and the temporary split solution with the more energy-efficient PoS consensus layer, the Beacon Chain. Transaction blocks will no longer be confirmed by solving computationally intensive puzzles. Image

1/ 🧵
How and why "data availability (DA)" became the sexiest topic in #Ethereum land, the #l222 space, and for #rollups
2/ Pre-2021 (roughly speaking), DA for most #blockchains wasn't a concern for 2 reasons:
1) most blockchains did not have enough usage to warrant any concern
2) the monolithic approach meant that each (full) node downloaded the entire block to check for availability no problemo
3/ However, this approach has its limitations/drawbacks, and, thus, new solutions like light clients, rollups (RUs), and the modular approach were implemented.

#Web3Learning

Scrolling down the twitter #blockchain community, and suddenly feeling clueless about some technical term?

Well, it happens a lot with me since I am quite noob to Web3 and Crypto Universe.

Here is my effort to explain one such jargon 👉🏽 #Sharding
1/n From the time since its inception, scalability has been a big concern for Blockchains.

As blockchains become more mainstream, its essential for networks to be scalable with high throughput for explosive growth.

Low gas fees + Ultra high TPS = Growth 🚀
2/n Initially, vertical scaling was the dominant solution.

Simply explained, add more power to all the nodes so they can compute hash and validate transactions faster.

But there is a maxima to the technological advancement of nodes. This limits the total network throughput 🤒

There's a lot of questions about #cassie, what is the significance, why is it cool, what does it demonstrate, how is it #web3. Even moreso since the #radflix demo dropped & the exposure it got on various socials etc so here is a thread...
Hopefully yall know by now that it is primarily a research network. It started as a collection of radical ideas around #consensus, #sharding, #blockchain and #cassie is the embodiment of those ideas to demonstrate viability. But it has now become so much more...
It is technology that can do things that were said to be impossible. Technology that can do things other L1 tech hasn't even dreamt of trying to do. It is a technology which is being used to show proof of potential on all the *hardest* things first...

1/ Why is #blockchain scaling so controversial? From the #blocksizewars to #Alt L1s and #rollups.

Is it really that hard?!

🧵 time...
2/ Blockchains like #Bitcoin and #Ethereum strive for maximum #decentralization and #censorship-resistance while remaining totally open and inclusive networks. However, they also want to scale to accommodate billions of users.
3/ As they stand right now, their limited capacity to process transactions at the base layer (~7 and ~20 TPS, respectively) are in direct opposition to achieving that goal.

The question is “What is the best method of scaling a blockchain?” 🧐

1/ @harmonyprotocol is building a multi-chain future that helps users transfer seamlessly between chains with instant transactions and extremely low fees💙

This feature by @WhiteboardCryp1 talks about how #HarmonyONE works.

👇Here are some excerpts
2/ What motivated the creation of @harmonyprotocol?

While the #Ethereum chain was growing, there were some limitations.

#HarmonyONE was built to create a fast, decentralized and secure solution for a billion users, focusing on Speed and Performance.
3/ Building on the promise, @harmonyprotocol achieved a 2️⃣-second finality on all transactions. This is way faster than other top blockchains.

But what about security risks?

🧵 THREAD N°18 : le trilemme de la #blockchain

Un nouveau thread sur la blockchain, un peu technique, mais qui est important pour bien comprendre les enjeux de cette technologie.

Le triangle d'or de la blockchain, thread du jour 👇 Image
1/ D'abord une description des 3 points du trilemme:

👉 #décentralisation : la blockchain, et en particulier le réseau de mineurs, ne doit pas être détenu par un petit nombre de personnes

👉 #scalabilité : la blockchain doit pouvoir accueillir un nombre croissant d'utilisateurs
2/ 👉 #sécurité : le point le plus important, sans sécurité il n'y a plus de #blockchain

Ces 3 points sont donc absolument nécessaires ; et pourtant, ils ne peuvent pas coexister.

Jusqu'ici, les blockchains n'ont pu obtenir que 2 points sur 3, et donc faire des compromis.

🧵 THREAD N°12 : comment accélérer la blockchain ?

@ethereum traite 15 transactions/seconde, alors que @Visa en traite plus de 1500, soit 100 fois plus.

Comment la blockchain peut-elle résoudre ce problème afin d'être adpotée par le plus grand nombre ? 👇
1/ Vous êtes peut-être déjà tombé sur les termes de layer 2, rollup, sharding... sans jamais comprendre de quoi il s'agissait.

Tous ces termes sont des solution que les développeurs ont mis au point face à un problème de la blockchain : celui de la rapidité des échanges.
2/ Avec la démocratisation de l'ETH, le nombre de transactions a explosé et le réseau est congestionné en permanence.

La blockchain a un problème d'échelle : elle n'est pas (encore) adaptée à une utilisation de masse. Des solutions ont donc dû être trouvées.

Thanks to colleagues at LBS for the opportunity to take stock of the decentralisation agenda in digital finance, from #bitcoin to #DeFi

A thread on the key points:

bis.org/speeches/sp211…
Blockchain has breathed new life into the idea of money as a substitute for a ledger that keeps score of who owes what to whom

"Money is memory" according to the classic 1998 by Narayana Kocherlakota

minneapolisfed.org/research/sr/sr…
#DeFi, or decentralised finance, is the latest manifestation of this idea where the ledger is much more elaborate than simply keeping score of who pays whom

Project #Alvarium in a nutshell:
Disrupt the #edge security model!

The edge remains a hostile environment for computing.
So, protecting #data in use thru a #data confidence fabric and #ConfidenceComputing is the objective of this @linuxfoundation project.

@IOTA @DellTech
How does #Alvarium work?

It implements a kind of #trust #sidecars for #data streams with trust metadata and confidence scores thus creating the data confidence fabric.

@IOTA @DellTech
Where does @IOTA and the #Tangle come into play in #Alvarium?

The #TrustSidecars (e.g., attached to #IoT devices) directly store the trust metadata in the #Tangle. Metadata consumers simply subscribe to updates on the Tangle.

■■■■■■■□□□ to ETH 2.0.

This monumental upgrade to Beacon Chain implies:
+ETH will shift from POW to POS i.e. you will now stake $ETH to yield more #ETH (1/4)
+Staking opens the doors for #sharding, aka splitting Ethereum into different chains where possibly tx of similar applications or group of transactions can live independently (64x scalability) (2/4)
+Rollups, a layer-2 solution which aggregates tx off-chain in safe smart contract to be settled later on-chain (100x scalability)
+Rollups on top of sharding (6400x scalability) (3/4)
