IPFs series - combination of IPFs and blockchain
2022-02-03 05:29:52 【Brick moving leader】
IPFS It is a decentralized file storage protocol , Based on this protocol, a file storage network can be realized by decentralization .
take IPFS Used as an object server
- The chain can record IPFS Returned after storage on cid
Use chain for IPFS Access control
visit IPFS need CA Certificate issued
Chain maintenance CRL
Use chain for IPFS Video charges for
The account system and payment system are put on the chain
Put the video file ipfs On
Use chain for IPFS File transactions
The seller is ipfs On Upload A small sample of the document
Smart contract realizes document exchange
Add the name of the file when it is on the shelf , describe , Price , The seller's public key , Sample link
Add the buyer's public key after the buyer places an order , Deduct money to the exchange
The seller uses its own private key and the buyer's public key to authenticate the file ECDH + AES encryption , Upload to IPFS
The seller adds a file link to the contract , Close the deal , Collect money
Buyer from IPFS Download files on , Use your private key and the seller's public key to decrypt (ECDH + AES), Enjoying !
The process is basically as above , There may be a risk of cheating money , Rules can be added to make it more perfect
according to EOS Introduction to the white paper ,EOS There will be a built-in IPFS Standard file system .IPFS And EOS The combination of can realize many useful application scenarios , Here are the introduction .
EOS The volume of transactions is very large , and 0.5s Will produce a block of data . If all the data is recorded on the main chain , Then there will be a huge amount of data . adopt IPFS It can greatly reduce the data storage cost of the main chain itself .
DApp When users access the front end, they need a static page Distribution Service , For example, auction an encrypted cat on Ethereum , Its front-end files are currently centralized . By putting these front-end programs or website front-end based on IPFS File storage on , Can achieve Web Decentralization and low cost of services . As you can imagine , Future in EOS There will be no need to buy ECs to develop applications on , You don't have to think about what kind of host you need 、 what CPU、 How much memory and hard disk , And what system to install 、 How to start Apache,DApp Developers only need to deploy the front-end code to IPFS, Deploy the smart contract of back-end business logic to EOS Just on the chain , And as long as the mortgage EOS Tokens, , All this is free .
If we want to EOS Make a similar YouTube Of DApp, Then we can put the account system and payment system in EOS On the chain , Put all front-end pages and video files into IPFS On . Through this architecture , The model of the whole payment system is very easy to implement , We can foresee this DApp The service should come soon .
In the Internet age, all documents are transmitted in the form of reproduction , This actually reduces the value of the document itself , In addition, piracy is rampant . If we pass EOS Realize a file transaction DApp, Then all documents can be passed through IPFS Storage , And encrypt with a key , The property right transfer on the chain can be realized by modifying the key , In order to achieve the purpose of document transaction . Ultimately, blockchain will bring value to the Internet era .
