StarkWare Quantum Bitcoin Transaction: First Quantum-Resistant BTC Transaction Hits Mainnet
StarkWare mentioned researcher Avihu Levy examined an experimental quantum resistant Bitcoin transaction on mainnet. It is reported that the TX spent a ten,000-satoshi output in block 964,199 with out altering Bitcoin’s consensus guidelines.
StarkWare described it as the primary transaction of its form. MARA Pool mined the block after receiving the transaction straight via its Slipstream service, because the nonstandard format meant bizarre nodes wouldn’t relay it via the general public mempool.
StarkWare spokesperson Nathan Jeffay mentioned the transaction price round $150 to $200 in computation, and StarkWare mentioned the method took hours. The demonstration reveals a option to shield a single output beneath Bitcoin’s present guidelines, however at a cloth computational and operational price.

How StarkWare Quantum Bitcoin Transaction Works
Levy’s Quantum-Safe Bitcoin (QSB) scheme, first proposed in April, combines hash-based one-time signatures with computational searches that bind authorization to a particular transaction. The building is meant to stop forgery even when a sufficiently succesful quantum pc breaks the elliptic-curve cryptography utilized by Bitcoin.
In March, Google researchers estimated {that a} sufficiently succesful quantum pc may theoretically derive a Bitcoin personal key 9 to 12 minutes after a public key turns into seen. Google mentioned this might permit an attacker to interchange a pending transaction throughout Bitcoin’s affirmation window.
Levy’s April proposal estimated that producing a transaction would require $75 to $150 in GPU computation; StarkWare put the price of the finished transaction at round $150 to $200.
QSB applies to particular person Bitcoin transactions relatively than upgrading cryptography throughout the community. It permits cash to be moved into an output with extra safety with out altering the Bitcoin protocol, nevertheless it doesn’t shield cash whose public keys have been uncovered earlier than migration. In that case, a possible attacker may have time to research these keys earlier than a protected transaction is shipped.
The transaction’s nonstandard classification beneath Bitcoin Core’s default relay coverage is a sensible constraint. Ordinary nodes don’t propagate the transaction earlier than affirmation, so it should be submitted on to a cooperating miner via a service reminiscent of MARA’s Slipstream. The technique, due to this fact, requires ready transactions and direct miner entry.
StarkWare CEO Eli Ben-Sasson mentioned QSB gives a security internet whereas protocol-level protections are developed. The demonstration establishes a workaround beneath the prevailing guidelines, relatively than altering Bitcoin’s underlying cryptography throughout the community.

The Protocol-Level Alternative
Bitcoin builders are individually contemplating proposals, together with BIP-360, a proposed smooth fork that may introduce a Pay-to-Merkle-Root output kind whereas eradicating Taproot’s quantum-vulnerable key-path spend. That strategy would require network-wide coordination and activation.
QSB doesn’t watch for a protocol change. The mainnet check reveals that Bitcoin’s present consensus guidelines can accommodate one type of quantum-resistant spending, whereas broader protocol-level protections stay into consideration.
