ERC-5559: Cross-chain Write Deferral Protocol

The following proposal is a superseding version of EIP-5559: Cross-Chain Write Deferral Protocol, aka CCIP-Write, replacing Ethereum L1 storage with L2 chains and cryptographically secure databases with an aim to cut gas costs and further privacy while retaining the secure aspects of on-chain storage. Methods in this document specifically target security and cost-effectiveness of write deferrals in context of databases. The cross-chain data written with these methods can be retrieved by generic EIP-3668-compliant contracts completing the cross-chain data life cycle.

Happy to hear comments & feedback.

This proposal has been amended to a standalone ERC and discussions now exist at: New ERC: Cross-chain Storage Router Protocol
