According to ChainCatcher and Cointelegraph, the long-dormant Bitcoin Improvement Proposal OP_CHECKTEMPLATEVERIFY (abbreviated as CTV or BIP-119) is currently gaining attention, supported by prominent Bitcoin developers and companies. If ultimately approved, it will enhance Bitcoin's scalability, security, and usability, particularly by introducing "covenants" and "vaults" features.
These features are expected to improve the self-custody experience and foster more secure and intelligent second-layer applications, such as Lightning Network and Ark.
