Project TestChain can provide a basic understanding of BlockChain.
testChain is a basic demo of Blockchain. This project is developed to get a basic idea of the workings of Blockchain
testChain is developed with Java , SHA256 Cryptographic algorithm and Mining of Blocks concept.
There are mainly 2 options to showcase the basic functions of a blockchain :
Display the Blockchain
Insert a block into testChain ( Mine new Block )
- Display the Blockchain✨
The display function will display all blocks in testChain with securely stored data, its hash and mining run (iteration counter of mine block to get specific hash ).
Before displaying testChain, all blocks must undergo 3 authentication checks (i.e. isChainValid function) :
a. registered hash and calculated hash must matched
b. previous hash and registered previous hash must matched
c. check if hash is solved or mining is completed
- Insert a block into testChain ( Mine new Block )✨
For mining of new block or insertion of block in testChain, data is taken from user. For Calculating Hash value SHA-256 Algorithm is applied on String containing previousHash, timeStamp i.e. minning start time in millisecond, data and miner. Block was mined by setting difficulty level 5 (It can be changed).
