StarkWare’s quantum-safe Bitcoin coding contest lowered the estimated GPU cost for building a transaction from about $320 in August to roughly $66 by Thursday morning. The contest ran for a week and used AI-assisted coding, and StarkWare said the participants made the computation about five times faster.

What this rests on

Claim by claim, with its source
✓
StarkWare said the contest began with an estimated GPU bill of about $320 for a quantum-safe Bitcoin transaction.
✓
StarkWare said contest participants using AI tools made the computation about five times faster.
✓
After a week of the Quantum-Safe Bitcoin Optimization Challenge, StarkWare said the estimate had fallen to about $67 on Wednesday and to $66 by Thursday morning.

What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

Bitcoin developers and contest participants can see that the cost estimate for this kind of transaction is now much lower than the earlier benchmark StarkWare described. That changes what is visible in the contest dashboard today, and it gives anyone following quantum-safe Bitcoin work a new reference point to compare against.

Market reaction

We track BTC, but we only have 0 price points in that window. The series is stored every half hour, so newer events will have it. Computing it from two points would not be a reaction, it would be a coincidence.

How the story was built

Every piece in order, with the time its news medium declares — if it is not believable we use ours and say so — and what it added to what was already known at that point. Arriving first is not the same as adding something.
