Revision history for agora

This format is based on Keep A Changelog.

Unreleased (Candidate for 1.0.0)

Modified

  • Fix several vulnerabilities and bugs found in staking components.

    Including:

    • Stake state token can be taken away
    • Privilege escalation: Acting on behalf of delegatee role + Unlocking delegated stakes
    • Delegatee can steal delegated inputs
    • Stake policy doesn't allow destroying multiple stakes

    Included by #195

  • Place a lock the stake while cosigning a proposal.

    NOTE: This changes how cosigning works. In particular, the stake has to be spent instead of just presented in the reference inputs. Also, adding multiple cosignatures in one tx is no longer possible.

    Included by #192

  • Support voting/retracting votes with multiple stakes.

    NOTE: Due to the fact that the order of stake locks is undefined, voting to multiple proposals in a single tx is disallowed.

    Included by #186

  • Fix a bug that allows an attacker to send two or more GATs to an effect in the winning effect group.

    Fixed by #181

  • Workaround currentProposalTime always returns PNothing, due to the fact that upper bound of txInfoValidRange is never closed.

    Fixed by #177

  • Fixed governor validator always fail because of the 0 ADA entry in txInfoF.mint. (#174)

    Fixed by #175

  • Standalone stake redeemers. This allows injecting custom validation logic to the stake validator easily. The behaviour of the default stake validator remains unchanged.

    Included by #172

  • Witness stakes with reference input. Stake redeemer WitnessStake is removed.

    Included by #168

  • tracing flag in ScriptParams of agora-scripts to enable/disable tracing in exported scripts.

    NOTE: This changes the representation of ScriptParams. In order to preserve old behavior, the flag must be set to True.

    Included by #167.

  • effects of Proposaldatum is now required to be sorted in ascending order. The uniqueness of result tags is also guaranteed.

    ProposalVotes should be sorted the same way as a result.

  • AuthCheck script is used for tagging GAT TokenName instead of effect script it is deployed at.

    Included by #161.

  • Use Credential instead of PubKeyHash

    Included by #158.

    NOTE: This changes the representation of the following types:

    • PStakeDatum
    • PStakeRedeemer
    • PProposalDatum
    • PProposalRedeemer

  • Use plutus v2 types.

    Included by #156.
