Sei vs TON

Sei is a parallelised Cosmos‑SDK Layer‑1 optimized for order‑book exchanges, using Twin‑Turbo consensus to reach 300–400 ms finality. Its built‑in matching engine lets dApps compose on a shared liquidity layer, and fee markets are denominated in SEI with bulk‑order discounts. The ‘V2’ upgrade adds EVM compatibility via SeiDB and WASM contracts side‑by‑side.

The Open Network (TON) is a sharded Layer‑1 originally designed by Telegram, featuring dynamic workchains and instant cross‑shard consensus through the Vertical Blockchain mechanism. The TON Storage and TON DNS services extend functionality beyond payments, whereas the Tap‑to‑Transfer feature has onboarded millions of Telegram users. A 2025 governance vote approved jetton fee burns to make TON mildly deflationary.
