PoC of PoS

[gztensor]

Node/Runtime

• Add Babe and NPoS pallets to runtime and remove Aura
• Update node for Babe and NPoS
• Remove Aura stuff from pallet_admin_utils
• Update chain specs
  • Localnet
  • Testnet
  • Finney
• Producing blocks!
• Ensure bag thresholds are correct
  • Updated bag thresholds with cargo run -r -p node-runtime-generate-bags -- --total-issuance 21000000000000000 --minimum-balance 500 out.rs
• Implement era_payout
• Check all new runtime apis implemented correctly
• Look into Treasury pallet or similar to collect Slashes, RewardRemainder, etc
• Look into malicious node tests and check chilling/slashing works correctly
  • https://github.com/paritytech/polkadot-sdk/tree/master/polkadot/node/malus
  • https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/zombienet_tests/functional/0002-parachains-disputes.toml
• Generate pallet weights

Parameters

• Check EPOCH_DURATION_IN_SLOTS value
• Decide on SessionsPerEra
• Decide on BondingDuration
• Decide on REWARD_CURVE (and where to take the reward from)
  • Discussed with Pineal team that we will start small (3%) and a large stake from OTF (or other trusted party) and then increase only if we need to to attract a more diverse validator set
• Decide on MaxNominators

Auxiliary

• Staking Miner
  • Get https://github.com/paritytech/polkadot-staking-miner working for Subtensor chain
  • Sync with Medulla about running this for our chain
• Look into NPoS UI options
  • Best option seems to be https://staking.polkadot.cloud/
• Decide if we want Nomination Pools
  • Let's start without nom pools
• Lazy enabling of freezes for subnet validator stakes (to allow using it for node validators)
• Figure out swap from Aura to Babe
  • Safest way is re-genesis, Const is in support
  • Re-Genesis paritytech/substrate#7458
• Re-genesis script

Runtime is not crashing anymore!

Next steps:

• Fix consensus (not producing blocks)
• Figure out swap from Aura to Babe without stopping the chain
