BNB Chain Quantum Defense Works In Test, But Transactions Become Much Slower
BNB Chain just tested new security that would protect it from future super-powerful quantum computers. It worked, but the network ran about 40% slower because the new security made every transaction much bigger. The BNB Chain team shared the results in a report this week. The new code passed the test, but each transaction grew about 35 times larger than before, which clogged the network during stress runs. Bigger Signatures Mean Smaller Blocks Each transaction needs a digital signature to prove it is real. Today that signature is 65 bytes. With the new quantum-safe method, the signature jumps to 2,420 bytes. The change is needed because future quantum computers could one day crack the math behind most modern blockchains. Bigger signatures take up more space in each block. Speed dropped from 4,973 transactions per second to 2,997 in cross-region tests. That hits BNB Chains stated TPS goals for the year. The discussion also covered why BNB Chain is investing heavily into infrastructure upgrades. The goal this year: • Increase throughput from 6,000 TPS to 20,000 TPS • Continue reducing latency and improving finality • Build infrastructure that can support both retail and… Smart contract activity slowed less, since those transactions are already large. The Voting Part Still Works Fast Validators are the computers
