Post-2015 Blockchain Evolution

Algorithm

Post-2015 Blockchain Evolution witnessed a shift from proof-of-work to more energy-efficient consensus mechanisms, notably proof-of-stake and its variants, impacting network scalability and security profiles. This algorithmic refinement facilitated the development of layer-2 scaling solutions, addressing transaction throughput limitations inherent in first-generation blockchains. Consequently, the evolution spurred innovation in decentralized finance (DeFi) protocols, enabling complex financial instruments and automated market making. Advanced cryptographic techniques, including zero-knowledge proofs, became increasingly integrated to enhance privacy and data integrity within blockchain systems.
