Bitcoin, the leading cryptocurrency, operates on its own blockchain, prioritizing security and decentralization. However, its limited interoperability with other blockchains hinders seamless asset transfers and DeFi integration. Cross-chain bridges could enable Bitcoin to interact with ecosystems like Ethereum, Solana, or Polkadot, unlocking use cases such as tokenized BTC in DeFi protocols or NFT marketplaces. While bridges enhance functionality, they introduce risks like smart contract vulnerabilities and centralization concerns, as seen in past bridge hacks. Bitcoin's conservative development approach values stability over rapid innovation, but growing demand for interoperability may push for scalable, secure bridge solutions. Balancing security with cross-chain capabilities is crucial to maintain Bitcoin’s dominance while expanding its utility in the broader blockchain ecosystem.
