Algorand's 140K quantum-resistant transfers outpace Sei's draft proposal

Algorand has shipped quantum-resistant cryptography into production while Sei Network's competing plan is still a draft proposal.

Algorand has processed more than 140,000 quantum-resistant transactions on mainnet since November 2025, running Falcon signatures — a NIST-selected post-quantum scheme — in live network activity, according to Algorand network data.

Sei Network's response, SIP-5, remains a draft proposal from July 2026 that would bind an ML-DSA-44 key to existing EVM addresses without moving funds or changing addresses, per Sei's documentation.

The gap between the two chains is measurable. Algorand's Falcon signatures land between 640 and 1,280 bytes depending on the variant, while Sei's ML-DSA-44 signature clocks in at 2,420 bytes. Sei's own documentation warns full post-quantum signatures could push bandwidth demand from 13 MB/s to as much as 1.57 GB/s at 200,000 TPS.

Algorand's Live Deployment vs Sei's Draft

Algorand plans native protocol-level Falcon accounts in Q3 2026, with the smaller Falcon-512 variant expected by the end of the year. Coverage is designed to extend beyond wallets into consensus, staking, and multisig, with broad protocol resilience targeted for the end of 2027.

Sei's SIP-5 is framed as an emergency-ready fallback while longer-term research continues. The proposal is open for community discussion and is not on mainnet. Sei also shipped Hermes, the final piece of its Giga Roadmap, a low-latency consensus protocol, in late July.

Why the Lead Matters

In a market that rewards shipped code over roadmaps, "we already did it" carries more weight than "we have a thoughtful plan." Algorand's early Falcon deployment and clear 2026-2027 milestones give it a tangible talking point most chains lack.

Quantum computing is not tomorrow's problem, but it is the kind of long-term risk institutions and serious builders eventually price in. Chains that treated it as engineering homework years earlier will look different from those treating it as optional marketing.

SEI trades near $0.04205, down 96.33 percent from its March 2024 all-time high of $1.145, per CoinMarketCap. Daily RSI sits at 33.18 with 24-hour volume of $23.1 million, down 13.56 percent, against a $308.63 million market cap. Support sits near $0.0412, with resistance clustered at $0.0469 and $0.0516.
