The invention discloses a
double chain-type cross chain trading Internet of blockchains model (golden monkey model) core
algorithm. Different from the traditional centralized architecture, the model has a fully-distributed and multi-
chain network architecture. Due to the fully-distributed architecture, easier expansion, easier extension and easier
fault tolerance are realized than the existing architecture. Each chain maintains the
self consistency, the consistency between chains does not need to be managed by a central organization but is maintained by a fully-distributed mechanism. Limitations from the previous centralized Internet of blockchains (
chain network, in short) are broken, all chains can operate in parallel on the model, and the trading efficiency and the network operation speed are improved. The model has a new financial market architecture,
extensibility is realized, a financial unit can randomly and easily enter or leave the network, and the large-scale network and a high transaction volume are supported. The model comprises participant blockchains and inter-chain blockchains, the participant blockchains or the inter-chain blockchains can be one or one group of financial institutions, the inter-chain
blockchain has a double-
chain structure, a trading
record and a balance account are separated, and cross chain trading is realized. A core
algorithm for trading between chains, particularly, a protocol
algorithm of enabling the inter-chain blockchains to assist two or more than two participant blockchains for mutual trading is provided, no centralized mechanism is needed, and the consistency of the whole network is maintained.
