First-layer extension solutions attempt to reinvent how to handle transactions (such as parallel processing through sharding) or how blockchain reaches consensus (such as PoS and PoW). Meanwhile, second-layer extension solutions focus on building overlapping networks on top of existing blockchain architectures to enhance performance and scalability. Both types of solutions aim to address the  trade-off between security, decentralization, and transaction speed that blockchain faces."}]}],"pr":"ea76d2a866bb91d94b9f7c79a1aca5bf7e166000d1be857c1cb033f467377fa3"}
