Charles Guillemet, CTO at Ledger, reflects on the future of Ethereum and the protocol’s potential to support Web3’s mainstream adoption.
"Things to know:

– Ethereum, the world’s second-largest blockchain by market cap, recently underwent a significant software upgrade called The Merge, shifting from Proof-of-Work to Proof-of-Stake consensus.

– While a successful transition, questions remain about Ethereum’s scalability and readiness for the next stage of Web3’s development.

– This article delves into Ethereum’s scaling challenges and evaluates its ability to meet mainstream adoption needs. It argues that, while a flawless scaling solution does not exist yet, Layer 2s including Optimistic and Validity Rollups hold the most potential for increased scalability with a good tradeoff for the blockchain trilemma.

– More precisely, optimistic and Validity Rollups, using ZKP technology, will be key in shaping the future of Ethereum by enabling trustless, complex, and permissionless transactions at scale. "

Very surprised that the hype around ZK rollup died before it even begins, for now, the best solution fo Ethereum scaling that is indeed working is Roll up, OP and Arb are two working solutions and I will rather bet on them than theories. Though people claim that ZK rollups are very promising and most of these ZK projects have been able to raise huge amounts of money there is a reason why Starknet is not gaining huge adoption and the most popular and successful Dapp on it is moving to Cosmos. As an investor, I will only play the game phase by phase

Vitalik Buterin, the co-founder of Ethereum, recently shared his opinion that ZK-Rollups are likely to be the primary Layer 2 scaling solution for Ethereum. He compared the two solutions, Optimistic Rollups and ZK-Rollups, and highlighted that ZK-Rollups are faster in terms of moving funds.

Optimistic Rollups and ZK-Rollups are both Layer 2 scaling solutions for Ethereum. Optimistic Rollups use a more optimistic approach to scaling, which means that they process transactions off-chain and assume that they are valid unless proven otherwise. On the other hand, ZK-Rollups use zero-knowledge proofs to validate transactions, which allows them to be more secure and private.

While both solutions have their advantages and disadvantages, it appears that ZK-Rollups are gaining more attention and adoption in the crypto community. According to L2beat, a website that tracks the TVL (total value locked) in Layer 2 solutions, ZK-Rollups have a higher TVL than Optimistic Rollups. Additionally, there are more ZK-Rollup projects in development, as listed on zkrollups.io.

It is important to note that many of these ZK-Rollup projects do not yet have their own tokens. This means that their success and adoption may not be reflected in the current market trends. However, it is clear that ZK-Rollups are a promising solution for scaling Ethereum and addressing its current scalability issues.
