The Solana blockchain is exploring quantum resistance through a partnership with Project Eleven, but early findings suggest the effort could come with a major tradeoff: upgrades aimed at making the network quantum-resistant may reduce its speed by up to 90%.
Last year, the Solana Foundation announced it was working with cryptography firm Project Eleven to improve the blockchain’s post-quantum security. As part of the collaboration, the first post-quantum signatures went live on a Solana testnet.
However, early results from the initiative indicate that achieving quantum readiness may be difficult. A recent report cited in the article says that strengthening blockchain security against quantum computing threats could affect performance.
The report states that upgrades designed to resist quantum threats require substantial data and computational resources. That additional overhead could slow the blockchain, potentially affecting usage over the long run.
Solana’s high transaction throughput is a key part of its appeal. The chain is positioned as faster and more scalable than rival networks such as Ethereum, which has contributed to strong network usage. If Solana reduces speed to pursue quantum security, it may weaken one of its main competitive advantages.
Analyst Crypto Patel said Solana has the potential to rally, but near-term gains depend on how the network handles scalability while pursuing stronger future security.
“Solana Is Testing Quantum-Resistant Cryptography, Staying Ahead Of The Curve. Whether $SOL Hits $1000 Next Alt Season Depends On How They Solve The 90% Speed Tradeoff,” the analyst said.
The article notes that Solana has continued to lead other networks by usage. It cites an X post by Solana Sensei stating that SOL processes 36 times as many transactions as Ethereum, despite Ethereum being five years older. It also says Solana has handled 106 billion transactions, compared with Ethereum’s 3.36 billion.
Despite the network’s usage and upcoming upgrades, SOL is described as trending bearish. CoinMarketCap data cited in the article shows SOL is down 35% year-to-date and is trading at $80 at press time, with a 2.2% intraday loss.

Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
