Ethereum founder Vitalik Buterin highlights a promising answer for implementing social restoration multi-chains in his latest submit, “Detailed Studying of Layer 2 Wallets and Different Use Circumstances”. The proposal consists of preserving a key vault and a number of wallets in several places.
These wallets will be capable of scan the keystore to replace their affirmation key picture or throughout every transaction affirmation course of.
Cross-chain proofs play an important function on this function and require deep optimization. Attainable options are zero-knowledge proofs (ZK-SNARK), ready for Verkle proofs, or non-obligatory KZG options.
Trying to the longer term, protocol aggregation must be realized, and by producing proofs of aggregation, transactions submitted by all customers are mixed, thus decreasing prices.
This integration might require bringing it into the ERC-4337 ecosystem, which can require some modifications to ERC-4337. On the identical time, L2 ought to be optimized to attenuate the delay of L1 state studying from L2.
Wallets could be positioned not solely on L2, but additionally on techniques which have a decrease stage of connection to Ethereum, reminiscent of L3 or a separate chain that solely comprises the Ethereum state root. Nevertheless, the keystore ought to be in L1 or a extremely safe ZK-stored L2.
Though this provides complexity, L2 keystore might show to be a less expensive answer in the long term. All through the method, efforts ought to be made to supply privateness safety options and guarantee compatibility with present privateness safety measures.
