How does my validator earn rewards?
Validators that participate in securing the Beacon Chain and execute "duties" get rewarded for this by new issuance of CTN. In addition, validators receive priority fees paid by users, and optionally MEV. Validators are rewarded for executing those duties by new CTN issuance to the "validator balance". The current APY can be seen on the official launchpad ↗.
| Type | Layer | Frequency | Amount |
|---|---|---|---|
| Attestation | Consensus | Once per Epoch (every 6.4 minutes on average) | 0.000014 CTN* |
| Block Proposal | Consensus | Every 2 months on average | 0.02403 CTN* |
| Sync Committee | Consensus | Every 2 years on average** | 0.11008 CTN* |
| Slashing Reward | Consensus | Very rarely included in Block Proposals | Up to 0.0625 CTN |
| Priority Fees | Execution | Included in every Block Proposal containing transactions | Typically 0.01 to 0.1 CTN; very rarely 1+ CTN |
| MEV Rewards | Execution | Also included in Block Proposals when using MEV-boost | Typically 0.01 to 0.1 CTN; very rarely 1+ CTN |
*Varies based on the total number of validators in the network. Estimate shown approximated for 435,000 active validators.
**These are subject to randomness; there can be "dry spells" multiple times longer than the average without being given one.
CTN on the Consensus layer is not liquid as it is being staked. Balances above 32 CTN will be automatically skimmed if a withdraw credential has been set, but to access the principal 32 CTN you will need to exit the validator.
Rewards provided on the Execution layer are liquid and can be accessed instantly.
Validator penalties
If the validator is offline and not executing its duties, it will be penalized at a rate slightly lower than the rewards for the same period of time.
Validators are penalized for small amounts of CTN if they are offline and fail to perform their assigned duties. This is called leaking. If a validator violates one of the core rules of the Beacon chain and appears to be attacking the network, it may get slashed. Slashing is a forceful exit of your validator without your permission, accompanied by a relatively large fine that removes some of your validator's CTN balance.
Realistically, the only condition that can cause a slashing is if you run your validator's keys on two nodes at the same time (such as a failover / redundancy setup, where your backup node accidentally turns on while your main node is still running). Don't let this happen, and you won't get slashed. Slashing cannot occur from being offline for maintenance.
Below is a table that shows the penalties that can happen to a validator:
| Type | Layer | Amount |
|---|---|---|
| Missed Attestation | Consensus | -0.000011 CTN* per attestation (-9/10 the value of a normal attestation reward) |
| Missed Block Proposal | Consensus | 0 |
| Missed Sync Committee | Consensus | -0.00047 CTN* per epoch (-0.1 CTN total if offline for the whole sync committee) |
| Slashing | Consensus | At least 1/32 of your balance, up to your entire balance in extreme circumstances |
*Varies based on the total number of validators in the network. Estimate shown approximated for 435,000 active validators.
Info
As a rule of thumb, if you're offline for X hours (and you aren't in a sync committee), then you'll make all of your leaked CTN back after X hours once you're back online and attesting.
