most of $BOOT stake is unstaked due to complexities related to multisig management

we need a tool for stake outsourcing to prog

successful deployment remove 2/3 of selling pressure from the market

details in finalization of $BOOT distribution

architecture of staking pools

pools have owners

• create and delete staking pool
• add and remove strategy
• set weights of strategies
• manual delegate, undelegate, redelegate
• update param

neurons can pool $BOOT for automatic staking according to strategy

• deposit to pool
  • adds deposit to contract balance
  • mints pool coin: fungible and transferable token
  • add deposit position to prog state
  • increase current deposit reserve
• withdraw from pool
  • burns pool coin
  • increase current withdraw reserve
  • add withdrawal position to prog state
  • when time comes
    • subtract contract balance

every strategy is standalone prog with strictly defined interface

• input: empty call
• output: array of validators with weights

prog have params according to which it self executes using dmn

• execution window in blocks
• max rebalance actions

on every execution step prog

• claim rewards
• calls each strategy
• read
  • current validator set including reserve
  • current staking positions of pool
  • current balance of contract
  • current withdraw reserve: measure of tokens for withdrawal
• executes expired withdrawals
• merge outputs recieved from strategies
  • normalization of strategy inputs
  • compute weights according to aggregated strategy
• make undelegate decisions
  • sum all withdrawals in current execution window
  • evaluate against aggregated strategy and sort by impact
  • executes top amount of undelegate limited by max rebalance actions
• make delegate decisions
  • sum all deposits in current execution window
  • evaluate against aggregated strategy and sort by impact
  • executes top amount of delegate limited by max rebalance actions
• make redelegate decisions
  • compute diff between current and target
  • sort list by the most impactful differences
  • execute top amount of redelegate limited by max rebalance actions

list of default strategies

specific validator

• ability to assign some relative percent to specific validator by pool owner

random validatory

• ability to make decision randomly
• support long tail of validators
• awesome to include validators from not active sets
• param: amount of validators chosen randomly

profitable validators

• contract compute apy of validators
• and responds with weights based on apy

this proposal does not include necessity to develop interface for staking pools

its expected to use them in hacklab with preloaded abi
