This repo is a fork of bitcoin-inquisition used to develop the opcodes of the MATT covenant proposal for bitcoin.

Active branches:

• checkcontractverify: contains the core OP_CHECKCONTRACTVERIFY opcode, and some basic tests.
• matt: the same as the previous branch, but also activates the OP_CAT opcode on taproot Scripts.
• mattplus: the same as the previous branch, but also contains the proposed OP_CHECKSIGFROMSTACK and OP_INTERNALKEY opcodes.

Archived branches:

• matt-vault: a demo of a simple vault construction posted to the bitcoin-dev mailing list (with an earlier version of the opcodes).
