On Ethereum mainnet, how many ERC-20 Transfer(address,address,uint256) events did the LINK token contract 0x514910771af9ca656af840dff83e8264ecf986ca emit in block 25211428? Answer with the whole number only.

Answer

event_count: Count each log emitted by the LINK contract at the named block whose topic0 is Transfer(address,address,uint256).
