Network Design

The eVESTX blockchain ecosystem has two chains, the main chain, and the side chain, both with different purposes, but following the same consensus logic. In the main chain, at any time a system node is designated as a leader to generate a History Proof sequence, providing the global network with reading consistency and a verifiable time passage. The Leader sequences user messages and orders them so they can be efficiently processed by other nodes in the system, maximizing throughput. The Side Chain runs side by side with the Main Chain, which, unlike the Main Chain, has EVM compatibility. EVM compatibility was chosen because the first practical and widely used smart contract platform is Ethereum. The implementation should leave room for the sidechain to keep up with more Ethereum updates. Staking-based consensus is greener and leaves a more flexible option for community governance.

Consensus: PoH and PoS

Proof of History is a sequence of computations that can provide a way to cryptographically verify the passage of time between two events. The verifying can still be done in parallel and it’s discussed in Section. Because the initial process is still sequential, we can then tell that things entered into the sequence must have occurred sometime before the future hashed value was computed. By periodically synchronizing the generators, each generator can then handle a portion of external traffic, thus the overall system can handle a larger amount of events to track at the cost of true-time accuracy due to network latencies between the generators.

This specific instance of Proof of Stake is designed for quick confirmation of the current sequence produced by the Proof of History generator, for voting and selecting the next Proof of History generator, and for punishing any misbehaving validators. The user can issue an unlink transaction to remove them. N is a dynamic value based on the proportion of stale and active votes. N increases as the number of stale votes increases. A supermajority is 2/3rds of the validators weighted by their bonds. A supermajority vote indicates that the network has reached consensus, and at least 1/3rd of the network would have had to vote maliciously for this branch to be invalid.

Sidechain

The Side Chain runs side by side with the Main Chain, which, unlike the Main Chain, has EVM compatibility. This means that most dApps, ecosystem components, and tools will work in the sidechain and require zero or minimal changes. Staking-based consensus is greener and leaves a more flexible option for community governance.

Scalable

Decentralized blockchain solutions have a scaling problem. In addition to low transaction rates, maintaining quick finality while the network scales is a major problem and many current solutions compromise decentralisation.

Through VestXHybrid's “Tsunami” network communication innovation, finality times reduce exponentially as the network grows. This means we can expect ~500ms finality up through 40s of thousands of nodes and beyond.
