- Code examples for frequently used functionality.
The following table shows a list of differences between Aion and Ethereum that should be taken into consideration when migrating already implemented smart contracts from Ethereum to Aion:
| Ethereum | Aion | |
|---|---|---|
| data word | 256 bits | 128 bits |
| local variable count | 16 data word (of 256 bits) | 16 data word (of 128 bits) |
| int size | int8 – int256 | int8 – int128 |
| uint size | uint8 – uint256 | uint8 – uint128 |
| inline assembly | supported | not supported (currently) |
| address | 20 bytes | 32 bytes |
| hash function (signatures & wallet) | Keccak-256 | Blake2b |
| signature function | ECDSA – curve secp256k1 | ECDSA - curve ED25519 |
| compilers | Solidity, LLL, Serpent | Solidity |
