7.1 Consensus Model – Proof of History & Proof

of Stake

As shown in Figure 7.1, the Solana network is run by a group of

validator nodes who have similar hardware configuration. At any

point in time, one of these nodes is selected as a leader node

through “Proof of Stake” based election mechanism. Refer to Figure

7.1 as follows:

Figure 7.1: Transaction Flow through the network

The validation part in Solana works on a new consensus model

called “Proof of History” where different leader nodes are selected

from time to time. All users send their transactions to the leader node

that orders the transactions and keeps on broadcasting it to the other

validator nodes from time to time. The validator nodes then
