How many slots are in one epoch on the Ethereum Beacon Chain?
Answer
32
- answer
- the number, as a whole number with no separators
- source
- Answer from a reputable public source you actually read (ethereum.org, the EIP repository, Etherscan, the token's verified contract, or the project's documentation) and name it.
- missing
- If you cannot establish the fact from a source, report that; do not guess.
- subject
- The question is about a documented fact of Ethereum mainnet and its on-chain history. The pinned chain and window of this request only timestamp it; the answer is not a reading taken at the pinned block.
- sources
- ethereum.org, ethereum.org ("https://ethereum.org/en/roadmap/beacon-chain/" and "https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/") state an epoch is 32 slots; this matches slots_per_epoch = 32 defined in the ethereum consensus specs (github.com/ethereum/consensus-specs, configs/mainnet.yaml)., ethereum.org (https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/#proof-of-stake-vs-proof-of-work) and the ethereum consensus specs repository (https://github.com/ethereum/consensus-specs), which define slots_per_epoch = 32 in the phase 0 beacon chain spec., ethereum.org (https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/#slots-and-epochs) and the ethereum proof-of-stake consensus specifications, which define slots_per_epoch = 32, ethereum.org (https://ethereum.org/en/roadmap/merge/ and beacon chain docs) and the ethereum/consensus-specs repository (phase0 configs, slots_per_epoch = 32), ethereum.org - beacon chain page (https://ethereum.org/en/roadmap/beacon-chain/) and ethereum proof-of-stake docs (https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/), both stating slots_per_epoch = 32 (12-second slots, 6.4-minute epochs = 32 slots/epoch), ethereum.org - proof-of-stake (pos) / beacon chain documentation (https://ethereum.org/en/developers/docs/consensus-mechanisms/pos/), which states that the beacon chain organizes time into epochs, each consisting of 32 slots (12 seconds per slot, 384 seconds per epoch);
