Is Bitcoin About to Freeze Its Own Coins? “The Cat” Proposal Divides the Community
Quantum computing stays a priority for Bitcoin and crypto markets, posing a safety menace to its underlying cryptography. However, a brand new menace emerges as a controversial “Cat” Bitcoin Improvement Proposal, sparking heated debate amongst builders about labeling tens of millions of inscription-related outputs as completely unspendable.
The draft BIP seeks to tackle considerations about blockchain bloat, elevating key questions round property rights and core Bitcoin ideas. Community responses vary from sturdy help to warnings about setting a dangerous precedent.
Bitcoin Developers Debate BIP “The Cat”: Proposal to Combat UTXO Spam from Ordinals and Stamps
Every Bitcoin transaction spends cash that got here from earlier transactions. The outputs of a transaction signify quantities of Bitcoin assigned to addresses. If an output hasn’t been spent but, it turns into an Unspent Transaction Output (UTXO).
Essentially, a UTXO is a bit of Bitcoin you’ll be able to spend in the future.
The plan addresses the current doubling of Bitcoin’s UTXO, set to over 160 million entries in 2023, a lot of which stems from Ordinals and Bitcoin Stamps.
In current years, Bitcoin’s Unspent Transaction Output set has grown considerably, posing challenges for node operators and miners. According to the draft discussion, UTXOs rose from about 80–90 million to greater than 160 million throughout 2023.
Now, practically half include fewer than 1,000 satoshis, with most serving as a type of storage fairly than for financial transactions.
This improve is primarily due to Ordinals inscriptions, which place information in Taproot witness fields, and Bitcoin Stamps, which create unspendable outputs by means of faux naked multisig addresses.
These strategies circumvent guidelines like OP_RETURN, initially created to discourage blockchain bloat by limiting non-monetary information. OP_RETURN’s 80-byte relay coverage decreased bloat, however current methods exploit new transaction codecs to retailer arbitrary information.
The affect is important. Each node should load the total UTXO set to validate transactions, driving up prices for miners and for anybody operating a number of nodes.
Bitcoin developer Mark Erhardt described Stamps’ use of the UTXO set as “in all probability, from a technical perspective, certainly one of the extra egregious makes use of of blockchain.”
Historically, Bitcoin has prioritized financial transactions and restricted information utilization. Bitcoin Core developer Greg Maxwell said of OP_RETURN limits, “Part of the concept right here is shaping conduct in the direction of conservative wants.”
However, each Ordinals and Stamps bypass these guidelines, which fuels arguments for stronger measures, akin to “The Cat.”
Inside “The Cat” BIP Proposal
The proposal introduces Non-Monetary UTXOs (NMUs), flagged by indexers with an NMU bit. Inscription-related outputs recognized on this approach would turn out to be non-spendable, making them unavailable as transaction inputs.
Nodes would prune these outputs, lowering storage wants and prices.
“New BIP proposal “The Cat” goals to radically fight spam from Ordinals and Stamps on Bitcoin: by freezing satoshis by means of consensus. The concept is to completely make tens of millions of small UTXOs used to retailer information non-spendable, eradicating these sats from circulation at the value of making an unprecedented precedent for the demonetization of satoshis,” wrote Livecoins, a poppular account on X.
Classification is dependent upon worth thresholds, specializing in UTXOs underneath 1,000 satoshis throughout sure home windows. When the function prompts, nodes would ignore these NMUs throughout transaction validation.
Advocates argue this deters spam economically, because it avoids ongoing technical filtering. Supporters, akin to TwoLargePizzas, imagine advantages prolong properly past one-time cleanup.
By making it clear that Bitcoin rejects non-monetary bloat, “The Cat” may deter future spam. Nona YoBidnes factors out that spam makes up 30–50 p.c of all UTXOs, calling the proposal “a robust anti-spam message” for the community.
The BIP targets tens of millions of mud outputs left unspent, every utilizing worthwhile assets. For large-scale providers, this cumulative burden means actual infrastructure prices and slower node sync instances for newcomers.
Debate: Property Rights and Bitcoin’s Core Values
Opponents current sturdy arguments, calling the proposal a drastic change to Bitcoin’s core properties. Greg Maxwell, a number one developer and privateness advocate, sees modest storage financial savings as little justification for “disabling UTXOs” and calls it “asset seizure,” undermining Bitcoin’s values.
Developer Ataraxia 009 warns the change “represents a harmful slippery slope.” By freezing sure UTXOs at the consensus layer, the door may open for future coin confiscation.
This difficulty resonates with a group centered on resistance to censorship and asset seizure.
The dialogue facilities on whether or not Bitcoin ought to discriminate between transaction varieties at the protocol degree.
Supporters see inscription spam as an assault to be stopped, whereas critics warn that this might empower the protocol to decide the legitimacy of any transaction.
If the community is keen to take away satoshis primarily based on their use, some concern broader interventions could observe.
The debate additionally explores Bitcoin’s id. Is Bitcoin only a financial system, or does its censorship resistance prolong to all legitimate transactions?
Supporters cite the custom of limiting information storage, however opponents be aware that Ordinals and Stamps are nonetheless legitimate underneath present guidelines.
Community suggestions is ongoing throughout the draft’s evaluation, earlier than any official BIP submission. The outcome will affect technical selections in addition to how Bitcoin balances core values and operational wants.
Regardless of “The Cat” consequence, the dialogue highlights tensions between effectivity and precept as Bitcoin continues to scale and face new challenges.
