Struct massa_models::config::constants::CHAINID

pub struct CHAINID {
    __private_field: (),
}
Expand description

node chain id (to avoid replay attacks)

By signing an operation with an ID of the target chain (e.g. whether the operation targets LABNET, BUILDNET or MAINNET), the user is protected from a malicious actor that could steal operations created on BUILDNET / LABNET and try to replay them on the Massa MAINNET (and potentially stealing real coins) Chain id idea and implementation come from Ethereum EIPs:

  • https://github.com/ethereum/EIPs/blob/master/EIPS/eip-155.md
  • https://eips.ethereum.org/EIPS/eip-1344 Chain id can be queried in Smart contracts (AssemblyScript: chain_id call) and in the jsonrpc get_status call
