Prioritised submission contract - coston 2

Fork for prioritised handling of Submission contract on Coston 2 network, starting Mar 7, 12:00:00 UTC.

v1.7.1806: Merge pull request #24 from flare-foundation/mod-public-ip-auto-config

This hard fork for Flare coston2/mainnet changes staking parameters according to Flare phase 2 staking rules. Phase 2 staking starts on September 7, 2023 at 00:00:00 UTC on coston2 and on October 1, 2023 at 00:00:00 UTC on mainnet.

v1.7.1805

This hard fork for Flare mainnet adds inflation-based staking. The hard fork time is June 20th, 2023 at 15:00 UTC, please upgrade your Flare mainnet nodes before that time.

The added function

func (e *ProposalTxExecutor) getCurrentInflationSettings(currentTimestamp time.Time) (uint64, uint64, uint64, uint32, time.Duration, time.Duration, time.Duration, time.Time)
takes the current timestamp of the P-chain, and returns parameters:

• minValidatorStake: the minimum stake that a validator can have on the network. uint64
• maxValidatorStake: the maximum stake that a validator can have on the network. uint64
• minDelegatorStake: the minimum stake that a delegator can delegate to a validator. uint64
• minDelegationFee: the minimum delegation fee percentage that is paid from the validator to the delegator. This will be set to zero in practice because rewards are disabled on the P-chain. uint32
• minStakeDuration: the minimum length of time that a validator can be staked on the network. time.Duration
• maxStakeDuration: the maximum length of time that a validator can be staked on the network. time.Duration
• minFutureStartTimeOffset: the time delay between when a staking transaction is made and when a validator can become active. time.Duration
• minStakeStartTime: the earliest date that a validator can set for their staking period to begin. time.Time

This enables a way to have future hard forks that change these parameters over time as more inflation has occurred on the network. Avalanche staking was originally designed for a capped supply asset, so this added function enables the same staking mechanism to be used with an uncapped supply asset.

v1.7.1804 Inflation-Based Staking (Coston2 testnet)

What's Changed

• v1.7.1804 Inflation-Based Staking in #11

Full Changelog: v1.7.1803...v1.7.1804

v1.7.1803

What's Changed

• Changed st.evm.Call to st.evm.DaemonCall in the state connector and governance settings code. This change improves the efficiency of the calls - in #10
• Added a hard fork executing on March 1st, 2023 at 15:00 UTC to shift the balance of the original distribution contract to a governance contract that will then pass the funds on to a new contract that conforms to the FIP.01 governance vote outcome. Hard fork announced on February 9th, 2023: https://twitter.com/JoshuaGEdwards/status/1623695363696648192
• Removed disabled code on the P-chain related to validator rewards.
• Updated versioning convention
• Updated Docker files and setup
• Updated unit tests
