Scaling Bitcoin is crucial for its mainstream adoption, and multi-layer solutions like the Lightning Network, Fedimint Protocol or Liquid offer exciting possibilities. The Lightning Network enables faster and cheaper transactions by settling them off-chain, while Fedimint provides decentralized identity verification to prevent fraud. Liquid creates a sidechain with faster confirmations and asset issuance capabilities. These layer 2 solutions allow Bitcoin to handle more transactions without sacrificing decentralization or security. By building on top of the main blockchain, they unlock new potentials for innovation that could revolutionize traditional finance systems.#Bitcoin #cryptocurrency
