Changes

EOSIO Reference System Contract Move

This release marks the creation of a seperate repository for the EOSIO reference system contract. All future work on the reference contract will be maintained here and the contracts in eosio.contracts will contain reference utility contracts.

Introduction of Staking Pools

The staking pool system, when combined with powerup, displaces (over time) the existing staking, voting, producer pay, and REX systems. Here are some of the major differences:

  • Users use powerup to obtain NET and CPU resources instead of staking (delegatebw) or renting from REX.
  • Users stake into pools to be able to vote instead of staking using delegatebw or buying REX.
  • Users stake into pools to receive ram fees, powerup fees, and namebid fees, instead of buying REX.
  • Inflation pays both producers and staking pools. Inflation occurs each round (126 seconds) and is scaled by pow(produced_blocks / 252, 10) to encourage the selection of reliable producers.

Producer Sorting

This version of the system contract changes the sorting of the top producing accounts from alphanumeric based on account name to location based using the location field in the producers table.

Optionally Build with setkvparams

Pull Request #4 allows the system contract to be built with the action setkvparams using the below build command:

cmake -DBUILD_TESTS=true -DSETKVPARAMS=1 ..

This action applies to any chain that has enabled the feature KV_DATABASE.
