POSDAO smart contracts are located in the contracts directory, which contains the root contracts as well as abstract and eternal-storage subdirectories. View the documentation by selecting a contract from the menu. To return to the repo, go to https://github.com/poanetwork/posdao-contracts

  • abstracts: base contracts that provide definitions to the root contracts.
  • eternal-storage: upgradeability and contract storage management.
  • root: POSDAO functional contracts.

Smart Contract Summaries

Note: Current documentation is complete for AuRa contracts only. HBBFT contract implementations are in progress and are not listed nor described here.

  • BlockRewardAuRa: reward generation and distribution.

  • Certifier: allows validators to use a zero gas price for service transactions such as reporting malicious validators and revealing secrets (see Parity Wiki for more info).

  • InitializerAuRa: Initializes upgradable contracts and is then destroyed. This contract's bytecode is written by the scripts/make_spec.js into spec.json along with other contracts.

  • RandomAuRa: generates and stores random numbers in a RANDAO manner (and controls when they are revealed by Aura validators).

  • Registry: stores human-readable keys associated with addresses (see Parity Wiki). Used primarily to store the address of the Certifier contract (see Parity Wiki for details).

  • StakingAuRa: contains the contract staking logic for candidates, delegators and validators.

  • TxPermission: controls the use of a zero gas price by validators in service transactions, protecting the network against "transaction spamming" by malicious validators.

  • ValidatorSetAuRa: stores the current validator set and contains the logic for new validators selection at the beginning of each staking epoch.
