Polkadot is a heterogeneous multichain with shared security and interoperability, composed of "relay chain + parachains", based on a multi-chain and heterogeneous sharding design based on nominated proof of stake (NPoS). There will be many different consensuses and parachains of different structures in the network. Each parachains has its unique data, P2P network architecture, and shares security by linking to the relay chain. The Availability and Validity (AnV) protocol of Polkadot is what allows for the network to be efficiently shared among parachains while maintaining strong security guarantees.
BitCherry is based on technology created IPv8 expandable blockchain infrastructure, according to the actual needs of different application scenarios do segmentation data, according to different types of content to provide the appropriate side chain, the main chain is only responsible for a consensus with the main transaction of Token, The number of side chains can increase with the increase of business volume and data. Nodes of different sub-chains handle their respective businesses and based on the design of a multi-layer systematic security assurance mechanism, to resist various attacks.
Sharding is based on the hashgraph division of the relationship graph. According to the six-degree split theory, the same type of relationship is usually concentrated in the surrounding small circles, and the relationship fragments from large to small form a hash circle, so the final 96% The above transactions are carried out in the same shard, cross-shard transactions will be greatly reduced, reducing a lot of unnecessary losses.
