The mystery of the discovery between Ethereum equal: discover the difference between DHT protocols and gossip
The world of cryptocurrency is known for its decentralized networks, but one aspect remains wrapped in mystery: as Bitcoin selects its peers for transactions. Two popular contenders for this task are the DHT protocols (directly threshold) and gossip such as the distance of Kademlia Xor. In this article, we will deepen the differences between these two approaches and because the developers of Ethereum have chosen to opt for a gossip protocol on a DHT.
dht: decentralized hash table
A DHT is a decentralized indexed storage system that allows the nodes to share data in a peer-to-peer way. The idea behind DHTS is to create a shared directory that contains all the files or data available on the network. When a new knot joins the network, it creates a voice in this directory and shares its files with other knots.
While DHT can be useful for sharing large quantities of data, they have some limitations when it comes to discovering even. To find new nodes to interact with, the DHTs are based on a central index that lists all available colleagues. If indexing is not performed efficiently, it can lead to low performance and reduction of scalability.
Gossip protocols: decentralized convergence
A gossip protocol, such as the distance of Kademlia Xor, is designed for the discovery of peers in decentralized networks. It works with multiple knots (peer) repeatedly sending queries to discover new connections. The most efficient peers are the ones who are closest to a distance and have not yet been questioned.
Kademlia Xor’s distance is a popular choice between researchers thanks to its simplicity and efficiency. Here’s how it works: when a knot sends a query, the answer includes the IDs of all the nodes at a certain distance (xor) from the sender. The receiving knot then uses this information to find new colleagues closer than they were before.
Because Ethereum chooses gossip about dht
So why didn’t the Ethereum team not opted for a DHT when he designed his network? There are several reasons:
* Scalability
: As the number of nodes on the network increases, the indexing overload in the DHT becomes a significant problem. With a gossip protocol such as the distance of Kademlia Xor, each knot must only keep contact information with its closest peers, making it easier to reduce.
* Performance : Gossip protocols are generally faster and more efficient than DHT -based index systems. Based on the nodes, periodically send query, it is possible to quickly discover new connections and reduce the time spent in the repeated interactions.
* Security : while both approaches have their inconveniences, gossip protocols provide better anonymity and safety due to the decentralized nature of the communication from knot to node.
Conclusion
The choice between a DHT protocol and a gossip like Kademlia Xor’s distance depends on the specific requirements of the network. In the case of Ethereum, the developers opted for a gossip protocol to ensure effective discovery of peers, scalability and performance. While DHT can be useful in some scenarios, they often have limitations that make them less suitable for complex decentralized networks.
While the panorama of the cryptocurrency continues to evolve, it will be interesting to see how the different protocols adapt and improve their approaches to discovery between peers. One thing is certain, however: the search for efficient and scalable networks is a crucial aspect of the construction of safe and resistant blockchain ecosystems.
