Blockchain technology has revolutionized the way we think about security, transparency, and decentralization. However, its scalability has become a significant bottleneck, hindering widespread adoption.
Blockchain scalability faces challenges such as slow transactions, network congestion and high energy consumption, but solutions like off-chain transactions, layer 2 scaling, and consensus algorithm optimization are emerging from the shadows. Notable projects including Polkadot, Solana, Ethereum 2.0, Cardano, and Bitcoin Lightning Network are pioneering these innovations to enhance transaction processing capacity and network efficiency.
