Add precompiled contract for Ed25519 signature verification

Verification of Ed25519 cryptographic signatures is obviously possible in EVM bytecode. However, the gas cost will be very high, and computationally expensive, as such tight, wide word operations intensive code as required for Ed25519 is no

Signature & Permit

Universal login / signup using ENS subdomains

This presents a method to replace the usual signup/login design pattern with a minimal ethereum native scheme, that doesn’t require passwords, backing up private keys nor typing seed phrases. From the user's point of view it will be very si

Localized Messaging with Signal-to-Text

An on-chain system for providing user feedback by converting machine-efficient codes into human-readable strings in any language or phrasing. The system does not impose a list of languages, but rather lets users create, share, and use the l

Scoped Approval Interface

This interface is designed for use with token contracts that have an "ID" domain, such as ERC-1155 or ERC-721. This enables restricted approval of one or more Token IDs to a specific "scope". When considering a smart contract managing token
