golang Block Chain

Blockchain

• A blockchain, originally block chain, is a growing list of records, called blocks, which are linked using cryptography.
• Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a merkle tree root hash).

Description

a block chain in golang with command line interface builtin.

Language

• golang

Usage

USAGE:

 • getbalance -address ADDRESS           - get balance for address.
 
 • createblockchain -address ADDRESS     - creates a blockchain.
 
 • printchain                            - prints the blocks in the blockchain.
 
 • send -from FROM -to TO -amount AMOUNT - send amount from an address to an address.
 
 • createwallet                          - creates a new wallet.
 
 • listaddresses                         - lists the addresses in our wallet file.

Utilities

• getbalance: $ $EXECUTABLE getbalance -address ADDRESS
  • To get balance of address 'ADDRESS'.
• createblockchain: $ $EXECUTABLE createblockchain -address ADDRESS
  • To create a blockchain and send reward to the address 'ADDRESS'.
• printchain: $ $EXECUTABLE printchain
  • To print the blocks in the blockchain.
• send: $ $EXECUTABLE send -from FROM -to TO -amount AMOUNT
  • To send amount AMOUNT from address 'FROM' to address 'TO'.
• createwallet: $ $EXECUTABLE createwallet
  • To create a wallet and store it in the wallets database.
• listaddresses: $ $EXECUTABLE listaddresses
  • To list all public addresses in the wallets database.

$EXECUTABLE evaluvates to:

• dev: go run main.go
• build:
  • First build the module. $ go build
  • After building the module. $PWD/go-blockchain
