Solana is an open source project implementing a new, high-performance, permissionless blockchain. The Solana Foundation is based in Geneva, Switzerland and maintains the open source project.
It is possible for a centralized database to process 710,000 transactions per second on a standard gigabit network if the transactions are, on average, no more than 176 bytes. A centralized database can also replicate itself and maintain high availability without significantly compromising that transaction rate using the distributed system technique known as Optimistic Concurrency Control [H.T.Kung, J.T.Robinson (1981)]. At Solana, we are demonstrating that these same theoretical limits apply just as well to blockchain on an adversarial network. The key ingredient? Finding a way to share time when nodes cannot rely upon one another. Once nodes can rely upon time, suddenly ~40 years of distributed systems research becomes applicable to blockchain!
