Wrapped Bitcoin is a tokenized form of bitcoin on other blockchains, often designed to track BTC 1:1 for DeFi and on-chain use.
Bitcoin layers split jobs across the stack: the base chain handles final settlement, while upper layers improve speed, cost, and app flexibility.
A simple explanation of Bitcoin sidechains: separate chains linked to Bitcoin that expand functionality while adding new trust and security trade-offs.
Bitcoin DeFi means using BTC in decentralized finance apps such as trading, lending, and liquidity tools, often through bridges or wrapped assets.
DeFi on Bitcoin is possible, but it usually relies on layers, sidechains, wrapped BTC, and different trust models than Ethereum-style DeFi.
A simple explanation of bitcoin side chains: separate chains linked to Bitcoin that add features while keeping the main chain focused on base settlement.
Yes. You can build dApps on Bitcoin, but the usual model is layered: Bitcoin handles settlement, while richer app logic lives off-chain or on upper layers.
