Recently, the founder of Ethereum Vitalik Buterin introduced the concept of shared security stating that hackers could attack a small network by purchasing a token or more than half of the token. He argued that independent L1s and side chains could lose everything. Buterin said the rollup was much safer and the assets could not be stolen because the rollup used evidence to validate the event. Buterin suggested that assets issued on one platform and then used in other chains could pose a security risk. He states: “This means” shared security”.
The founders of Ethereum also shared a chart detailing the various combinations consisting of maximum and minimum security for asset holders. He added that Optimism, Arbitrum, ZkSync, and StarkEx [Rollup Mode] are already backed by Ethereum. However, Avalanche and Ethereum Classic did not fall into this “shared security zone”.
The creator of Ethereum strongly criticised the Bitcoin Satoshi Vision (BSV). He called the BSV/BSV security setup chain “weak”. Buterin said the proof-of-work consensus mechanism and large blocks make the chain “easy to attack.” In this regard, the Bitcoin Satoshi Vision is not the only one to be criticized. Earlier, Buterin criticized Bitcoin Cash (BCH) and said it was “basically a failure.” However, the reason was not the security of BCH, but the community of the project.
