In the ever-evolving world of cryptocurrency, Bitcoin faces yet another pivotal moment. A new Bitcoin Improvement Proposal (BIP), nicknamed ‘The Cat’, has sparked heated debate throughout the crypto community. The proposal aims to freeze millions of inscription-related UTXOs (Unspent Transaction Outputs), effectively reducing blockchain bloat and node costs. However, some see this as a potential violation of property rights and a risky precedent for the future of Bitcoin.
Understanding UTXOs and the Growing Problem
To understand the controversy, it’s important to grasp the UTXO concept. A UTXO represents a certain amount of Bitcoin assigned to an address that remains unspent. Each Bitcoin transaction creates new UTXOs, and the Bitcoin network must track all of these to ensure validity. Recently, Bitcoin’s UTXO set has more than doubled, hitting over 160 million entries in 2023, largely due to data-heavy activities such as Ordinals inscriptions and Bitcoin Stamps.
Both Ordinals and Stamps exploit Bitcoin’s Taproot witness fields and transaction formats to store arbitrary data, bypassing past rules like the OP_RETURN relay policy that was designed to discourage non-monetary data storage. As a result, many UTXOs today contain less than 1,000 satoshis and serve as storage rather than for transactions, causing significant strain on the Bitcoin network.
What Does ‘The Cat’ Proposal Entail?
‘The Cat’ BIP introduces Non-Monetary UTXOs (NMUs), flagged by indexers with a specific NMU bit. Proposed changes would make inscription-related outputs non-spendable and prune them from the blockchain, reducing the burden for nodes and miners. Essentially, these outputs would be permanently removed from circulation, helping Bitcoin combat economic spam.
Supporters of the proposal, such as popular account TwoLargePizzas, argue that this measure could not only clean up current inefficiencies but also deter future abuses of the system. They see the move as a powerful anti-spam statement for Bitcoin’s future, particularly as inscription-related outputs account for a significant proportion of blockchain bloat.
Supporters vs. Critics: A Divided Community
While the proposal has gained traction among some developers and advocates of a streamlined blockchain, it also faces strong opposition. Critics argue that flagging certain outputs as non-spendable risks undermining core Bitcoin principles, including its resistance to censorship and confiscation.
Bitcoin Core developer Greg Maxwell has labeled ‘The Cat’ proposal as an example of “asset seizure”, cautioning against the negative precedent it could set. Others, such as privacy advocate Ataraxia 009, warn about the slippery slope of protocol-layer interventions, stating, “If we begin freezing certain UTXOs for spam prevention, what’s stopping future confiscations of coins for other reasons?”
Bitcoin’s Identity Crisis
The debate ultimately brings to light a deeper question about Bitcoin’s identity: Should Bitcoin remain exclusively a monetary system, or does its censorship resistance also protect the usage of its network for non-standard data storage? Proponents of ‘The Cat’ see it as aligning with Bitcoin’s historical priority on monetary transactions, while critics argue that censorship resistance is one of Bitcoin’s bedrock values and should apply to all valid transactions under current rules.
The Future of ‘The Cat’ and Bitcoin
Community feedback surrounding the draft is ongoing, with developers and enthusiasts continuing to voice their opinions as the proposal awaits official submission. Whether ‘The Cat’ gets adopted or not, the discourse surrounding it serves as a reminder of the tensions between efficiency and Bitcoin’s founding principles.
As Bitcoin progresses into a new era of scalability and innovation, balancing its operational needs with its commitment to decentralized values will remain a critical challenge.
