Many alternative blockchains that have emerged recently are classified as “EVM” chains, meaning they operate exactly like but have a different execution layer. This helps the cross-compatibility of smart contracts across chains, but it doesn’t solve some of the crucial problems embedded in the EVM system. In particular, it hasn’t improved how user accounts are handled and protected. Ethereum , a layer-1 blockchain, is trying to change that pattern with its account model.
Flow account model Since there can be multiple keys for one account, the way Flow creates addresses is also unique. Unlike Ethereum—where addresses are derived from the public key—Flow account addresses are created with an internal on-chain checksum at the protocol level. This ensures addresses are unique but also makes them much easier to read and use. On other blockchains, it can be very easy to mistype or have bad punctuation and send assets to the wrong address.
