Account is the basic identity of an agent on the blockchain. An account is identified by its address.
In Parallelchain Mainnet, accounts are divided into two types:
- Externally Owned Accounts (EOA): The address of an EOA is the public key of the keypair that is compatible with
- Contract Accounts: A contract account is created from contract deployment. The address is the hash of the concatenation of a contract's bytecode and the nonce of the EOA that deploys the contract.
Elements inside an account include:
- Nonce: The number of transactions made to the blockchain under this account.
- Balance: The balance of the account.
The followings are elements that only apply to Contract Accounts:
- Contract Code: The binary of the contract that was deployed to the blockchain (applies to Contract Accounts).
- CBI Version: The version of the Contract Binary Interface.
- Storage Hash: The 32-byte SHA256 root hash of its Storage Trie. This is empty for an External.
Notes: These accounts cannot be distinguished from each other just by looking at the address format.
A Network Account is a single identified network-wide account that maintains the state of ParallelChain Mainnet. This account is not associated with Ed25519 material. The network-significant data that the Network Account stores are composed of various fields:
- Previous Validator Set: The set of pools that form the validator set in the previous epoch. The stake in this validator set is locked until the next epoch.
- Current Validator Set: The set of pools that form the validator set in the current epoch.
- Next Validator Set: The limited-size pools with the largest powers. These will become the validator set in the next epoch.
- Pools: The set of pools that are accepting stakes and currently competing to become part of the next validator set.
- Deposits: The locked balance used to determine the amount of stake that can be contributed to a pool.
- Current Epoch: The current epoch number.
