Staking rewards are just an accumulator (Vyper 🐍)
Staking rewards look complicated. They are not. I went through a pile of articles on staking, and the mechanism is simpler than I expected. If you are going to ship a staking pool, you need to understand this model. The naive way First thought: an offchain bot that pays everyone every block. @bot.on_ ( chain . blocks ) def distribute_rewards ( block ): for staker in stakers : token . transfer (…
Staking rewards are frequently described as an accumulator, but in reality, they are a simpler mechanism that lives on-chain. Rather than paying out rewards every block through an offchain bot, the model can be implemented by tracking each staked token's accrued earnings over time and settling users only when they interact with the pool.
To implement this on-chain staking rewards system, you can use Vyper, a Python-like language for writing smart contracts on the Ethereum blockchain. The process involves storing the total supply of staked tokens, the balance of staked tokens for each user, the index representing the accrued rewards, the reward rate, and the timestamp of the last period update.
By tracking the accumulated rewards per token and maintaining offset values for each user, you ensure that every staker is paid accurately for the time they have been in the pool, without any penalties for periods of inactivity. This simplifies the staking rewards process and eliminates the need for complex onchain gas calculations or live bots.
