In this blog post we will briefly walk through the Mina protocol incentives and cover staking rewards calculation.
Staking economics is very important for proof of stake (PoS) networks. Proper incentives help blockchains to maintain properties such as immutability and censorship resistance, building a solid foundation of node operators securing the network participating in consensus.
Most PoS networks implement continuous token emission to incentivize node operators and delegators. Mina is not an exception. There is no cap of a max MINA supply as it grows every block. Every canonical block (successfully produced block written in the main chain) contains a coinbase (block reward) that is distributed to a node operator that produced it.
Currently, block rewards are fixed at 720 MINA to constitute the inflation of 12% assuming that all tokens are staked. In future it is expected for block rewards to be dynamic targeting inflation depending on a staking ratio to incentivise participation in staking. The less tokens are staked the higher will be the coinbase.
Token emission will decrease periodically until it reaches 7% annually. This schedule can be changed by the community via governance procedure in future.
For token holders, staking is important to avoid dilution of their total share in Mina network. Some MINA tokens are locked for a certain period of time. They are not transferable but capable of being delegated or staked. Coinlist token sale participants and those who purchased MINA on exchanges have unlocked MINA that can be transferred to any Mina address.
To further incentivise staking every address without locked Mina will receive a higher return on its Mina due to supercharged coinbase.
In Mina periods are split into epochs that last approximately 14 days and 21 hour. Staking operations like delegating and undelegating are executed immediately, but effects are applied only a couple epochs later due to Mina specifics. Stake distribution and balances are fixed for a particular epoch and any changes are taken into account with a time lag of 1-2 epochs.
Epoch consists of 7140 slots, each is a period of time when node operators can create a block and produce SNARKs (proofs for transactions that compress the size of a blockchain). Currently it lasts ~3 min, but it can be shortened in future.
Chances of being selected as a block producer are proportional to the node operator's stake. The final output is determined by a verifiable random function (VRF). Multiple pools can be assigned with the same slot potentially resulting in a short-range fork that will be resolved by Ouroboros Samasika.
In fact, all accounts delegated to a particular pool participate in the VRF distribution to win the slot. Staking pool that is being delegated by the winning account can compete for the slot and receive a reward if the block was selected by the consensus rules as a canonical one. In general, coinbase is 720 MINA at the moment, but if the account that was assigned to that slot holds only unlocked tokens - coinbase is doubled being equal to 1440 MINA.
There is no slashing in protocol rules, but rewards to delegators are distributed by block producers manually, pro rata to their share in the pool. It is important to select a reliable block producer as malicious actors can withhold rewards, which will result in a time lost for re-delegating to another pool. In case of a supercharged block, share of delegators with unlocked tokens is doubled to reflect their contribution to the increased coinbase (mechanics might differ among block producers).
There are ~24 epochs in a year and APR will vary in a short period of time (a few epochs) but should smoothen in the long term as more epochs pass. To define expected annual staking return we can extrapolate epoch performance to future periods. This method doesn't give us precise results but allows us to see which epoch had better return compared to others.
annual_apr = epoch_reward / epoch_balance * n_epochs_year
epoch_reward = total_pool_epoch_rewards * (1 - pool_fee) * delegator_share
delegator_share = delegator_epoch_balance / total_pool_stake
Calculation above doesn’t take fees into consideration. The more epochs are aggregated for averaging the better is the approximation of annual staking return. It also doesn’t take compounding into account, but it is possible to summarise actual rewards for a year and see the overall annual return.
In Mina, rewards received from delegating are staked automatically by design. Try to use a simple spreadsheet to check your epoch rewards. We provide reward reports for P2P delegators by request, visit p2p.org/mina for more details.
Note, that payout is not always equal to an epoch reward as some pools (including P2P) distribute rewards more frequently, so you will need to add up those. If you have questions, feel free to join our telegram chat. We are always open for communication.
