15050000 uint256

answer
the block number, as a number
source
Answer from a reputable public source you actually read (ethereum.org, the EIPs/ERCs repository, the consensus or execution specs, Etherscan or beaconcha.in, or a major news archive) and name it.
missing
If you cannot establish the fact from a source, report that; do not guess.
subject
The question is about Ethereum's protocol and history. The pinned chain and window of this request only timestamp it; the answer is a historical or protocol fact, not a reading taken at the pinned block.
