Go blockchain implementation

Primary LanguageGo

go-block

My own blockchain implementation in Go using sha256 hash and badger db.

  • Go version 1.16.2 darwin/amd64

Installation

  1. Install Go
  2. run git clone git@github.com:anishagg17/go-block.git in the terminal.
  3. cd into the directory.
  4. run go mod tidy in the directory

Development

  • Run go run main.go --help to get all the applicable commands.
Usage: 
 add -block <BLOCK_DATA> - add a block to the chain
 print - prints the blocks in the chain

  • Run go run main.go add -block "data" to add a new block with data="data" into the blockchain.

  • Run go run main.go print to print the entire blockchain. Demo output :
