BlockChain 4.0 is integrated of blockchain , cloud computing, Docker container and P2P filesystem.

The sample description is :

1)Developers program the software application like cloud application.

2)Developers add the docker file of the application to smart contract and submit to blockchain.

3)Upload the source code of application to software repository based P2P filesystem,for example:IPFS.

4)The buyer pay the token to smart contract and get the docker configuration , run the docker configuration of the application on any containered platform , cloud or local computer.

5)Application docker images download the code from the software repository based P2P filesystem,and run the application.

1)The contract includes container configuration text, it simplify the solidity language of Ethereum blockchain. Any application developer can code the Dapp with their best program language, don’t learn new contract language.

2)All of code and application are pulled to repository of P2P source code version control system based P2P distributed file system, it will be well maintened and update ,upgrade, special all code and application can be tracked and audit . Only trade record will be recode on blockchain . All of operation data will be recoded to P2P distributed file system, they are tracked and audit.

3)If there are bug and vulnerability , the owner of Dapp can update the code of P2P version control system to fix them and push the new Dapp to the customers. The customers only need to stop the Dapp and sync the new version Dapp and run it again. All of solution do not need to update the contract on the blockchain.

4)The container technology can help Dapp run on the any operation , it can help Dapp scale horizontally very efficiently and stability. Blockchain 4.0 will making full use of cloud computing advantages.
