==Abstract==
Prior soft forks (BIP 34, BIP 65, and BIP 66) were activated via miner signaling in block version numbers. Now that the chain has long since passed the blocks at which those consensus rules have triggered, we can (as a simplification and optimization) replace the trigger mechanism by caching the block heights at which those consensus rules became enforced.

In addition, this mechanism for code deployments have been deprecated in favor of BIP 9 deployments, which offer several advantages (please see [https://github.com/bitcoin/bips/blob/master/bip-0009.mediawiki BIP 9]).
Thus we propose elimination of the logic implementing these kinds of deployments, by replacing the test which governs enforcement of BIP 34, BIP 65, and BIP 66 with simple height checks, which we choose to be the block height triggering the 95% activation rule on mainnet for each of those deployments. This simplification of the consensus rules would reduce the technical debt associated with deployment of those consensus changes and simultaneously provide a performance optimization.
