The is the first article deep diving into individual covenant proposals that have reached a point of maturity meriting an in depth breakdown. CHECKTEMPLATEVERIFY (CTV), put forward by Jeremy Rubin with BIP 119, is the most mature and fully fleshed out covenant proposal, not only out of the proposals we will be covering, but out of all of the covenant proposals in their entirety. As I mentioned in the introduction article to this series, there are many concerns in the ecosystem regarding covenants that are too flexible enabling things that wind up having very detrimental consequences for Bitcoin. CTV was designed specifically to constrain its capabilities tightly enough to avoid any of those concerns. To first understand how CTV functions, we need to understand the individual parts of a Bitcoin transaction. This is a very high level view of a Bitcoin transaction. It has inputs, or unspent coins (UTXOs), and outputs, the new unspent coins that the transaction will create when it is confirmed in a block. There are a lot more pieces we will go through, but this is the highest level view of a transaction’s structure. Every transaction also has a version number field for the whole transaction, indicating applicability of new versions of rules or features. There is also the marker and the flag, which are set to specific values to indicate the transaction uses Segwit. After this is the input count, the number of inputs in the transaction. Then come the actual inputs. Each input contains a TXID of the transaction that created the unspent coin being spent, a VOUT which marks what output in that transaction is being spent, the size of the ScriptSig, and the ScriptSig, which is the unlocking script proving the input being spent is authorized by its locking script rules, and finally a Sequence number which is used to ensure the input being spent is following relative timelock rules. i.e. the input has existed for a certain number of blocks or length of time since its creation. The output count is the next piece of data, the number of outputs in the transaction. After this comes the actual outputs, which contain an amount of satoshis assigned to that output, the ScriptPubKey size, and the actual ScriptPubKey, which is the locking script for that output. Lastly the nLocktime field applies a timelock value in timestamp or block height that applies to the entire transaction. Each Segwit transaction also contains a Witness section, where each input has a corresponding witness containing a Stack Items count, how many things will be put on the script stack, a Size field for each item, and the actual data Item to go on the stack. CTV is an opcode that enables the most basic form of introspection and forward data carrying out of all the covenant proposals. It allows a script to take a pre-defined 32 byte hash and compare that against a hash of most of the fields of the spending transaction. If the hash derived from the actual spending transaction does not ma in a formal or creative style for better SEO.Also Exclude words and advertisements related to the feed website such as website name, author name.
