# ckBoost for Bitcoin

Welcome to **ckBoost**, a permission‑less liquidity layer that lets anyone receive any **Chain‑Key asset** (ckBTC, ckETH, ckUSDC, and future tokens) on the Internet Computer **before** the corresponding transaction is fully confirmed on its native blockchain.

> **Why it matters:** Native blockchains impose confirmation delays—e.g., \~60 minutes for 6 Bitcoin blocks, \~3 minutes for 12 Ethereum slots—before a Chain‑Key (ck) version can be minted. **ckBoost** eliminates this wait by matching each incoming deposit with **Boosters**: liquidity providers who advance the ck‑version immediately, then redeem the underlying asset once finality is reached.
