Veritas

A basic blockchain written in Go

Setup

$ go get -u github.com/boltdb/bolt
$ go get -u gopkg.in/yaml.v2

Usage

Creating and Using a Portfolio

A Portfolio stores multiple Wallets and is saved locally to portfolio.dat by default

$ ./Veritas createportfolio

$ ./Veritas listaddresses

Creating a Wallet

A Wallet stores your Public/Private key under an address (an encoded hash of your public key)

$ ./Veritas createwallet

$ ./Veritas balance -address 00964c39164c3936ab7aa1fd1a705b053c29af849166d5caf2

Creating a Blockchain

A Blockchain requires an address to send the reward for mining the genesis block

$ ./Veritas createblockchain -address 00964c39164c3936ab7aa1fd1a705b053c29af849166d5caf2

Sending Moolah

Sending money through a transaction requires your address, the recipient's address and an amount. The transaction is then stored in the mining queue and is not valid until it is mined

$ ./Veritas send -from 00964c39164c3936ab7aa1fd1a705b053c29af849166d5caf2 -to 004010e8a7e8a537cad8fc348baf7748625f77ab3f4206f302 -amount 1

Mining Blocks

Mining a block requires an address to send the reward and the number of transactions to put into the block. The difficulty of the block increases the more transactions it contains

$ ./Veritas mine -address 00964c39164c3936ab7aa1fd1a705b053c29af849166d5caf2 -num 5

Finding a Transaction

Finding a validated transaction on the chain requires the ID of the transaction

$ ./Veritas find -id 8b7074a7d711a0abc4565d7a83aa1374191b385f7a42c7d84d6fa080e60a3631

Other Shenanigans

You can print the full blockchain using printchain

$ ./Veritas printchain
