Solana is a blockchain platform that aims to solve the scalability problem by using Proof-of-History (PoH) as the first component. It positions itself as a fast, secure, and censorship resistant blockchain.
In the Solana environment, each block contains a hash of the VDF (Verifiable Delay Function) results of its predecessor. In this way, anyone on the network can check the time elapsed between any two operations, which gives an additional layer of security.
Solana also supports a system of smart contracts that developers can write in a large number of programming languages that support LLVM (including Rust and Cuda). The goal is to provide support for smart contracts in absolutely any language in order to increase accessibility for developers.
Solana can currently process 50,000 transactions per second. A network stress test is available on Solan’s website to prove it.
