The existing public-chain platform is mainly used for the digital currency transaction record, the transaction data are all on-chain and open. Compared with transaction data, large scale IoT data are not scalable for on-line data storage. At the same time, data is the core asset of IoT system, which needs to be encrypted. Therefore, we need to carefully design off-chain and on-chain data, and establish efficient connection between off-chain and on-chain, so as to realize the efficient and safe flow of data assets. CPChain proposes a parallel distributed architecture PDash, which consists of two parallel distributed networks: distributed cloud storage layer and blockchain layer.

The initial version of PDash has just made its debut last week. You can check out its code on github. PDash aims to build a healthy ecosystem that promotes data sharing among the vast users. You can imagine the wallet as a secure housekeeper for your data, the market as an information portal, the content distribution network as the safeguard for data transmission, and finally the blockchain as a law enforcer that regulates how tokens are distributed from the consumer to the provider.
