What kind of contract proposals are being considered for Bitcoin in 2025?

February 19th What kind of contract proposals are being considered for Bitcoin in 2025?

Jeremy Rubin is urging the Bitcoin development community to build a consensus under the Bitcoin Judica research institute for contract proposals to improve trading, security and programming efficiency. Bitcoin is well known for its conservative development culture, but the application of contracts can open advanced financial applications, open safes, and improve expansion without decentralization. But the debate is still happening between supportive supporters and those worried about changing the basic design of Bitcoin.

Major contract proposals

This is a summary of the top covenant proposals being discussed.

1. ON_CHECKEMPLATEVERIFY (CTV)

• Summary: CTV allows transactions to help enhance transaction efficiency, congestion control and privacy without allowing prior spending terms and allowing any calculations.
• Applications: Vault, Payment Group, Congestion Control, Lightning Network Factory.
• Status: Suggested and discussed in BIP-119, but not fully consensus.

2. OP_CHECKSIGFROMSTACK (CSFS)

• Summary: With CSF, scripted Bitcoin validates signatures from any data and opens the same capabilities as smart contracts. This allows you to build more complex transaction structures while ensuring safety.
• Applications: Union System, Safe Vault, Discaler Log Agreement (DLC), and Multi Signature Security Security.
• Status: Consider CTV for the original contract upgrade.

3. OP_CAT and arithmetic and encryption activities

• Summary: OP_CAT (data connection) has been removed from Bitcoin, but is now considered to be reintroduced along with elliptical digital manipulation and curves. These additions will improve Bitcoin’s scripting capabilities.
• Application: Smart contracts are evidence of more flexible and advanced encryption and an improvement in multi-signature schemes.
• Status: Controversial due to concerns about complexity and potential security risks.

4. OP_VAULT

• Summary: OP_VAULT is designed to enhance Bitcoin security by imposing wait times before providing a recovery mechanism in the event of hacking or loss of locks.
• Applications: Advanced security management solutions, Bitcoin storage for organizations, and theft protection.
• Status: Positive developments with proposed BIP-345.

5. OP_TXHAS

• Summary: These suggestions extend CTV by allowing scripts to commit to the transactional part rather than the entire output. This gives you more flexibility while maintaining CTV decisions.
• Application: Smart contracts are more advanced and improve lightning networks and custom payment terms.
• Status: Still in the initial discussion and development stages.

6. anyprevout (apo)

• Summary: First designed to upgrade your Eltoo Lightning network, APO allows signed transactions without accurate input, allowing for flexible payment structures and updating non-interactive channels.
• Applications: Lightning Network (ELTOO), State Chain, Payment Team Upgrades.
• Status: Suggested on BIP-118 and is currently under evaluation.

7. OP_TAPLEAF_UPDATE_VERIFY (TLUV)

• Summary: In TLUV, the script TapRoot can change the internal tree structure, execute conditions for future use, and provide a more advanced version of Covenant Bitcoin.
• Application: Allows smart contracts against fraud and dynamic contract structures.
• Status: Discussed with pilots.

8. Catt (all contract)

• Summary: CATT is a comprehensive contract frame that integrates OP_TXHAS, OP_CAT, CSFS and arithmetic activities into an integrated system, allowing developers to enhance flexible smart contracts.
• Applications: Extend multipurpose trading forms, decentralized financial applications, and second-class solutions.
• Status: Still in the theoretical stage, the components are developed independently.

9. Matt (merkleize everything)

• Summary: Matt uses Merkle Trees to implement smart contracts against fraud, allowing complex programming conditions without relying on external authentication mechanisms.
• Applications: Safe Vault, JoinPools, Multi -Stage Financial Contracts.
• Status: In the first idea stage and test.

So which suggestions are most supported?

Currently, CTV and CSF are the two most widely discussed proposals and are the most supported. They are considered minimal improvements, but offer great benefits such as transactional and congestion control without increasing excessive complexity.

OP_Vault is attracting attention thanks to its ability to enhance the security of Bitcoin depositories by allowing for wait times. This is especially useful for long-term storage and organizations.

Issues and outlooks

Some proposals such as OP_CAT and CATT promise great potential, but they run into resistance due to concerns about complexity and security risks. Achieving consensus in the Bitcoin community is always a major challenge, but if successful, these upgrades will open up a more flexible and competitive way for Bitcoin to be in the digital finance space.

The end result depends on the ability to find commonalities between developers and the broader Bitcoin community.
