OP Mainnet vs TON

OP Mainnet (Optimism) is an optimistic rollup that batches transactions to Ethereum and relies on fraud proofs submitted during a seven‑day challenge window. The Bedrock upgrade in 2023 cut L1 calldata costs by 40 % and introduced multi‑proof modularity. ‘RetroPGF’ rounds redistribute protocol revenue to public‑goods builders, governed by the OP token‑holder Collective.

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.
