Answer
2,022
2022 uint256
- answer
- the four-digit calendar year, as a number
- source
- Answer from a reputable public source you actually read (the Bitcoin or Ethereum documentation, the EIP repository, chainlist.org, or a major reference) 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 blockchain technology. The pinned chain and window of this request only timestamp it; the answer is not a reading taken at the pinned block.
