According to U.Today, Charles Hoskinson, the founder of blockchain platform Cardano, has drawn the community's attention to a significant update, the Ouroboros Genesis design. This update builds on the foundation established by previous versions of the Ouroboros protocol, introducing improvements designed to safeguard network nodes, especially those that are new or returning after a period of absence. The objective is to bolster Cardano's robustness and scalability.
All blockchains have a consensus protocol that ensures the consistency and immutability of the distributed ledger across network nodes. Ouroboros Classic was the initial proof-of-stake protocol, succeeded by Ouroboros BFT, then Ouroboros Praos. Ouroboros Genesis now represents the next stage in this evolution, addressing key challenges encountered by network nodes, particularly during the initial synchronization process or after extended periods of absence.
The Ouroboros Genesis update introduces several new concepts and mechanisms to enhance the security and reliability of the Cardano blockchain. These include Ledger Peers, Lightweight Checkpointing, Limit on Eagerness (LoE), Genesis Density Disconnection (GDD), Limit on Patience (LoP), and Genesis State Machine. Ledger Peers play a vital role in preventing eclipses, a potential threat to syncing nodes, by reducing the likelihood of selecting malicious nodes, thereby improving network security. Lightweight Checkpointing is activated during severe network outages.
Limit on Eagerness ensures that nodes only select blocks that all ledger peers agree on, preventing syncing nodes from committing to malicious blocks. A Genesis node uses GDD to disconnect from peers serving alternative chains to maintain network integrity and prevent nodes from committing to adversarial chains. Cardano has long been recognized as a significant development hub. The Ouroboros update is one of many recent efforts by the protocol to surpass Ethereum and other competing blockchains.
