BIP-110 is a proposal for a temporary soft fork that restricts data storage in transactions. Miners signal support for a soft fork by setting a specific bit in the block version field, as defined by BIP-9 (Version bits with timeout and delay). BIP-110 uses version bit 4. A block is counted as signaling when bit 4 is set in the block version, i.e. (version & (1 << 4)) != 0.

Note: version bit 4 was previously used by BIP-91 (Reduced threshold Segwit MASF) during the SegWit activation in July 2017, which explains the cluster of signaling blocks visible around that time.
