EVM
The Ethereum Virtual Machine is the runtime environment in which smart contracts are executed. Multiple EVM-compatible chains share the same account and contract model.

Atomic settlement means payment and delivery are completed simultaneously in the same on-chain transaction, with the whole thing rolling back if either party fails; it is usually implemented via smart contracts on EVM chains, on the premise that the delivery result can be confirmed on-chain or by a verifiable oracle.
EAS (Ethereum Attestation Service) is a general-purpose attestation protocol running on EVM chains, where any address can make an on-chain statement about arbitrary data; the statement is recorded as an attestation containing fields such as issuer, recipient, schema, timestamp and whether it has been revoked.
ecrecover is a built-in precompiled contract of the Ethereum Virtual Machine whose purpose is to "recover the signer's address given a message hash and an ECDSA signature", requiring no private key, no network connection, and no reliance on centralized services.
Hedera Smart Contract Service (HSCS) is compatible with the Ethereum Virtual Machine (EVM), allowing developers to write contract logic in Solidity
Computations running in the Ethereum Virtual Machine (EVM) must be deterministic, prohibiting floating-point operations, access to external data, and random number generation.
