Solana is a highly functional open source project that implements a new, permissionless and high-speed layer-1 blockchain.
Created in 2017 by Anatoly Yakovenko, a former executive at Qualcomm, Solana aims to scale throughput beyond what is typically achieved by popular blockchains while keeping costs low. Solana implements an innovative hybrid consensus model that combines a unique proof-of-history (PoH) algorithm with the lightning-fast synchronization engine, which is a version of proof-of-stake (PoS). Because of this, the Solana network can theoretically process over 710,000 transactions per second (TPS) without any scaling solutions needed.
Solana uses a 256-bit secure hash algorithm (SHA-256), a set of proprietary cryptographic functions that output a 256-bit value. The network periodically samples the number and SHA-256 hashes, providing real-time data according to the set of hashes included on central processing units.
Solana validators can use this sequence of hashes to record a specific piece of data that was created prior to the generation of a specific hash index. The timestamp for transactions is created after this particular piece of data is inserted. To achieve claimed huge numbers of TPS and block creation time, all nodes on the network must have cryptographic clocks to keep track of events rather than waiting for other validators to verify transactions.
