The following BIPS are deployed for testing:

• BIP 118 Any Previous Output (https://github.com/bitcoin/bips/blob/master/bip-0118.mediawiki)
• BIP 119 Check Template Verify (https://github.com/bitcoin/bips/blob/master/bip-0119.mediawiki)

Configuration example (tests must be disabled for now):

./configure --disable-tests --disable-bench --disable-fuzz-binary

TODO & Known Issues:

So far things have only been tested in regtest mode, so starting with --regtest is recommended

• Drivechain tests
• BIP 118 tests
• BIP 119 tests
• BIP 345 tests
• Withdrawal Refunds disabled
• Chain param seeds empty
• HandleMainchainReorg functionality disabled
• Withdrawal object blind tx hash is a random uint256 instead of blinded tx hash - see https://github.com/LayerTwo-Labs/bitcoin/blob/6571f9c5e18dfc8987177cc2db452372225ef9aa/src/rpc/blockchain.cpp#L2793-L2796
• Peering hasn't been tested, and headers syncing is probably broken by BMM changes (TODO)
• No replay bytes / replay protection
• No DoS score code copied (where did that move?)
