Abstract

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 not a good fit for the EVM bytecode model. The addition of a native compiled function, in a precompiled contract, to the EVM solves both cost and performance…
