🗄 A DNS server using the high-speed Solana blockchain as the backing datastore. (WIP)

K2 is the current settlement layer within Koii and provides the functionality of a message hub to other systems in the network. Thanks to the incredible work of the Solana Labs team, K2 is able to use Proof of History to achieve 0.2-second transaction times and thousands of transactions per second.

Proof of History in Golang. Taking key concepts from the Solana whitepaper and providing examples in Go

Proof of History is the primary consensus algorithm used in the popular blockchain architecture Solana. We have demonstrated the implementation of the Proof of History model using Python.

Les mécanismes de consensus permettent de se mettre d'accord sur une version commune et unique des données partagées par une blockchain, et ce, malgré la possible présence de nœuds défaillants ou malveillants. Le solde et l'état du réseau doivent être synchronisés sur la majorité des nœuds pour éviter les problèmes de double dépense.

A runtime execution model that allows blockchain transactions to be executed in parallel speculatively, while ensuring a deterministic final order. It reduces lock contention, adapts throughput dynamically to network conditions, and improves stability under high load without sacrificing consensus safety.

Sunchain is a lightweight Go prototype for a proof-of-history + proof-of-stake inspired L1 node, paired with a static explorer UI that showcases live block feeds, validator health, and staking UX.

A proof-of-history (PoH) implementation using Digests trait (allowing for multiple hash functions) while maintaining easy to use API and advanced features.

A measurement study of Solana transaction inclusion: 17 senders raced head-to-head, timed in Proof-of-History ticks.
