Rootstock vs Sonic

Rootstock (RSK) is a Bitcoin sidechain that brings EVM-compatible smart contracts to Bitcoin. It is secured by merged mining, which lets Bitcoin miners secure Rootstock at the same time as Bitcoin, and uses RBTC, a token pegged 1:1 to BTC through the PowPeg bridge, as its native gas token. Launched in 2018, Rootstock is one of the longest-running Bitcoin smart contract platforms and hosts lending, stablecoin and DEX protocols that let BTC holders use their bitcoin in DeFi. RIF is the token of its infrastructure services.

Sonic is an ultra‑fast EVM Layer‑1 claimed to reach 400k TPS and sub‑second finality via a custom SonicVM and DAG‑based consensus dubbed Tempo. Blocks are final once two‑thirds of stake attest, and state is stored in an in‑memory ledger that snapshots to disk every epoch. The project focuses on GameFi and real‑time social dApps, with an incentive testnet launched in May 2025.
