Cryptocurrency Blockchains

Architecture

Cryptocurrency blockchains represent a foundational paradigm shift in distributed ledger technology, enabling decentralized record-keeping and transaction verification without reliance on central authorities. This architecture typically employs cryptographic hash functions and consensus mechanisms, such as Proof-of-Work or Proof-of-Stake, to ensure data integrity and immutability. The layered structure, encompassing data, network, and application layers, facilitates the development of diverse decentralized applications and financial instruments. Scalability remains a key architectural challenge, driving innovation in solutions like sharding and layer-2 protocols to enhance transaction throughput.
