3.1. Solana Network

Solana is a web-scale blockchain that provides fast, secure, scalable, decentralized apps and marketplaces. The system currently supports 50,000 TPS (Transactions per second) and 400 ms block times. The overarching goal of the Solana software is to demonstrate that there is a possible set of software algorithms using the combination to create a blockchain. So this would allow transaction throughput to scale proportionally with network bandwidth satisfying all properties of a blockchain: scalability, security and decentralization. Furthermore, the system is able to support an upper bound of 710,000 TPS on a standard gigabit network and 28.4 million TPS on a 40-gigabit network.

Enrex.io has chosen Solana to be the main architectural stepping stone for its business endeavours mainly because of the open-source nature of Solana's network. As it is clearly stated on Solana's homepage, its main function and the raw attraction is "to support all high-growth and high-frequency blockchain applications and to democratize the world's financial systems."

Solana introduces a different class of consensus mechanisms for blockchains called proof-of-history (PoH). Being that it is the main invention of Solana, proof-of-history is derived from proof-of-stake protocol architecture. The difference is that PoH utilizes a Verifiable Delay Function which requires validators in the blockchain to solve these functions continuously. A specific sequence of steps is being evaluated.

Thus, PoH replaces traditionally implemented timestamps with specific time tracing inside the block before and after any action taken, to such an extent, that now a user can track the historical record of any event as proof of a specific point in time the given event happened.

Likewise, Solana employs a turbine of sorts, which lets the blockchain not cram its peers but transmit transaction data in packs to different validators before getting them to the peers.

Having these two innovative solutions deployed, Solana is the definitive choice for Enrex.io, which by default ensures its service is secure, verifiable and fast.
