U.In the present day – the co-founder just lately wrote an insightful article that delves into the technical challenges related to bettering interoperability between Ethereum Layer 1 (L1) and Layer 2 (L2) options. As L2 adoption will increase, the necessity for simpler layer-to-layer interactions turns into extra urgent.
Buterin’s writings level to 2 main issues. First, as customers start to carry belongings on numerous L2s and L1s, a way is required for customers to alter their entry keys throughout a number of accounts with out requiring a excessive variety of transactions. Second, Buterin notes the necessity to take care of counterfactual addresses; these are addresses that aren’t but registered on the chain, however ought to maintain funds securely.
Supply: Vitalik Buterin To deal with these points, Buterin presents a singular structure generally known as asset/keystore separation. On this mannequin, customers would preserve a keystore contract containing their verification key and the principles for altering it. Moreover, pockets contracts on L1 and a number of L2s would learn the cross string to retrieve the verification key.
Two implementations of this method are proposed. The “lite model” would require every pockets to retailer the verification key regionally and replace it with cross-chain proof of the present state of the keystore. The “heavy model” would require cross-chain proof for every transaction, which might make keystore updates cheaper however enhance prices per transaction.
Buterin identifies 5 sorts of proof schemes that might be used, starting from Merkle proofs to Verkle proofs, every with their very own strengths and weaknesses. Above all, it emphasizes the necessity for cross-chain proof, which must be extremely .
In the long term, aggregating proof by user-submitted grouping operations can scale back prices. Moreover, Layer 2 options ought to reduce the latency of studying Layer 1 state. Wallets will also be positioned on methods with decrease Ethereum connections, similar to Layer 3 or break up chains. Nevertheless, the keystore have to be stored both on layer 1 or on high-security, zero-knowledge layer 2s.
In accordance with Buterin, proper now, Ethereum is actively transferring in direction of higher cross-chain interactions, asset/keystore separation, and a larger concentrate on privateness.
