Compared with Zilliqa, which is also based on sharding technology, the two technologies are not quite the same

The coin safety was announced on May 16. Harmony, Launchpad's new project, is being sold in tokens. The lottery will start at 14:00 p.m. on May 28, 2019.

It is worth noting that this sale willNo longerRestrict Chinese user participation

The following is the report published by Blockbeats on May 14:

Blockbeats news, May 15 on the coin exchange's Launchpad will soon launch a new project Harmony. This is a new public link that aims to create a sharding based public link for tens of millions of people with high concurrency, high decentralization, high security, low latency, and low service charges.

This block chain based on PoS consensus attracted some investment institutions, including lattice Capital, consensus Capital, Continue Capital, Lemniscap, QTUM and other well-known investment institutions in the industry have invested in Harmony.

In full sharding, the Harmony network would have tens of thousands of nodes. The whole network consists of one beacon chain and several sharding chains. Beacon chains are used for random beacons and identity registration, and sharding chains are used to store individual blockchain states while processing transactions. Harmony proposes an algorithm that generates randomness by combining verifiable random functions (VRF) and verifiable delay functions (VDF). At the same time, PoS is combined in the sharding process, which transfers the security consideration of sharding from the minimum number of nodes to the minimum number of voting nodes.

Compared with Zilliqa, which is also based on sharding technology, the two technologies are not quite the same.Zilliqa only sharded the network and the transaction. In simple terms, it divided the network of 1000 nodes into 10 parts, and the transaction could be processed by 100 nodes of each part of the network simultaneously. And in order to do that,Each node of each shard needs to store the entire ledger of the blockchain.

While Harmony's sharding is state sharding. Suppose there are three nodes A, B, C and these nodes need to verify data T. State sharding divides data T into three parts: T1, T2 and T3. After that, A, B, and C will store and validate one of the sections, respectively.
