Unreleased

nym-contracts-v1.1.2 (2022-12-07)

Added

• Added migration code to the mixnet contract to allow updating stored vesting contract address to make it easier to deploy any future environments (#1759,#1769)
• Added an option to pledge additional tokens without the need to rebond minxode (#1679)
• Added support for node families (#1670)

nym-contracts-v1.1.0 (2022-11-09)

Changed

• mixnet-contract: rework of rewarding (#1472), which includes, but is not limited to:

  • internal reward accounting was modified to be similar to the ideas presented in Cosmos' F1 paper, which results in throughput gains and no storage or gas cost bloat over time,
  • introduced internal queues for pending epoch and interval events that only get resolved once relevant epoch/interval rolls over
  • the contract no longer stores any historical information regarding past epochs/parameters/stake state for the purposes of rewarding
  • a lot of queries got renamed to keep naming more consistent,
  • introduced new utility-based queries such as a query for reward estimation for the current epoch,
  • mixnodes are now identified by a monotonously increasing mix_id
  • bonding now results in getting fresh mix_id and thus if given node decides to unbond and rebond, it will lose all its delegations,
  • mixnode operators are now allowed to set their operating costs as opposed to having fixed value of 40nym/interval
  • rewarding parameters are now correctly updated at an interval end
  • rewarding parameters now include a staking supply scale factor attribute (beta in the tokenomics paper)
  • node performance can now be more granular with internal Decimal representation as opposed to an u8
  • node profit margin can now be more granular with internal Decimal representation as opposed to an u8
  • mixnode operators are now allowed to change their configuration options, such as port information, without having to unbond
  • mixnode unbonding is no longer instantaneous, instead it happens once an epoch rolls over
  • it is now possible to query for operator and node history to see how often (and with what parameters) they rebonded
  • other minor bugfixes and changes
  • ...
  • new exciting bugs to find and squash

• vesting-contract: optional locked token pledge cap per account (#1687), defaults to 10%

• vesting-contract: updated internal delegation storage due to mixnet contract revamp (#1472)

Added

• vesting-contract: added query for obtaining contract build information (#1726)

nym-contracts-v1.0.2 (2022-09-13)

Added

• vesting-contract: added queries for delegation timestamps and paged query for all vesting delegations in the contract (#1569)

Changed

• mixnet-contract: compounding delegator rewards now happens instantaneously as opposed to having to wait for the current epoch to finish (#1571)

Fixed

• vesting-contract: the contract now correctly stores delegations with their timestamp as opposed to using block height (#1544)
• mixnet-contract: compounding delegator rewards is now possible even if the associated mixnode had already unbonded (#1571)
• mixnet-contract: fixed reward accumulation after claiming rewards (#1613)

nym-contracts-v1.0.1 (2022-06-22)

Added

• mixnet-contract: Added ClaimOperatorReward and ClaimDelegatorReward messages (#1292)
• mixnet-contract: Replace all naked - with saturating_sub.
• mixnet-contract: Added staking_supply field to ContractStateParams.
• mixnet-contract: Added a query to get MixnodeBond by identity key (#1369).
• mixnet-contract: Added a query to get GatewayBond by identity key (#1369).
• vesting-contract: Added ClaimOperatorReward and ClaimDelegatorReward messages (#1292)
• vesting-contract: Added limit to the amount of tokens one can pledge (#1331)

Fixed

• mixnet-contract: estimated_delegator_reward calculation (#1284)
• mixnet-contract: delegator and operator rewards use lambda and sigma instead of lambda_ticked and sigma_ticked (#1284)
• mixnet-contract: removed expect in query_delegator_reward and queries containing invalid proxy address should now return a more human-readable error (#1257)
• mixnet-contract: replaced integer division with fixed for performance calculations (#1284)
• mixnet-contract: Under certain circumstances nodes could not be unbonded (#1255) (#1258)
• mixnet-contract: Using correct staking supply when distributing rewards. (#1373)
• vesting-contract: replaced checked_sub with saturating_sub to fix the underflow in get_vesting_tokens (#1275)
