What it is
Bitlayer is a new layer on Bitcoin that makes it faster and smarter.
Key parts
BitVM Bridge: Move BTC in and out safely
YBTC: A Bitcoin token that can earn yield
Rollup: Runs apps fast but settles on Bitcoin for security
How it works
You lock BTC → get YBTC → use it in DeFi → burn YBTC → take back your BTC.
Gas fees are paid in real BTC.

Security & limits
BitVM fraud proofs keep it trust-minimized.
Right now, there’s still one rollup operator.
Token
BTC is used for gas
BTR is for governance and ecosystem rewards
Why it matters
Bitlayer turns Bitcoin from just digital gold into something you can use, trade, and earn with across different blockchains.
