Solana tests post-quantum signatures — and the results have sparked one of the most important conversations in crypto right now. 

Working with Project Eleven, the Solana Foundation deployed a live testnet with quantum-resistant cryptography. New signatures came in up to 40x larger than current ones. 

Network speed dropped by roughly 90%. The tradeoff is real. But what Solana did next is what matters.

The Falcon Convergence

Two of Solana’s core developer teams — Anza and Jump Crypto’s Firedancer — studied the post-quantum problem separately.

They reached the exact same answer: a signature scheme called Falcon. That kind of independent agreement carries weight. It means the choice was driven by technical merit, not convenience.

Falcon was selected by NIST as an approved post-quantum security standard. It signs off-chain. 

Verification is straightforward. And it is built to stay dormant until quantum computers actually pose a real threat. 

Blueshift’s Winternitz Vault — already live on Solana for over two years — was also cited directly by Google Quantum AI in a published whitepaper.

Speed vs Security — What Are the Charts Saying?

SOLUSD (Weekly): As of May 04, 2026 (13:32 UTC), SOL trades at $84.18. It has fallen sharply from its cycle high above $200.

The weekly MACD histogram has turned green at +2.08. That is the strongest bullish momentum reading on this timeframe since mid-2024. 

The MACD and signal lines are in a confirmed bullish crossover. Both are trending upward. 

Price is sitting on the cyan horizontal near $84. This level capped the 2023 recovery. It is now being tested as support. A weekly close above it would be a significant technical development.

SOLBTC (Weekly): Against Bitcoin, SOL sits at 0.0010661. The cycle high was 0.0031010. 

The Parabolic SAR at 0.0012790 remains above price — the BTC-pair trend is still bearish. But the MACD lines at -0.0000096 and -0.0001117 are compressing.

They are curling toward each other near the zero line. On the weekly chart, this pattern has come before some of SOL’s sharpest BTC-relative recoveries. The crossover has not happened yet. The lines are moving.

The Race Nobody Else Has Started

Project Eleven CEO Alex Pruden  said it plainly: “This is a tomorrow problem — until it’s today’s problem.” 

Google’s research puts the quantum deadline at 2029. Solana is the only major L1 with a live testnet and a named solution already in GitHub. 

If the network that prepares first survives — what does that say about every blockchain still waiting?
