bitcoin_demo

A bitcoin block chain demo with Golang, contains full base function, eg : mining, transaction, wallet(privake key, public key, address), signature, verify and so on.

Useage

1. Generate key pair
2. Create block chain
3. Send transaction
4. Get balance
5. Print blocks or transaction

For example:

  api := API{}
  api.GenKeyPair()
  api.GenKeyPair()
  api.GenKeyPair()
  api.GenKeyPair()
  addrList := api.listAddress()
  addr1 := addrList[0]
  addr2 := addrList[1]
  addr3 := addrList[2]
  addr4 := addrList[3]
  api.createBlockChain(addr1)
  fmt.Println("send----------------------")

  api.send(addr1, addr2, 10, addr1)
  api.send(addr1, addr3, 10, addr1)
  api.send(addr1, addr4, 10, addr1)

  api.send(addr2, addr3, 1, addr1)
  api.send(addr2, addr4, 1, addr1)
  api.send(addr3, addr4, 1, addr1)

  fmt.Println("getbalance ----------------------")
  api.getBalance(addr1)
  api.getBalance(addr2)
  api.getBalance(addr3)
  api.getBalance(addr4)

  fmt.Println("printAllBlocks blocks----------------------")
  api.printAllBlocks()

  fmt.Println("printAllBlocks tx ----------------------")
  api.printTx()
  fmt.Println("over")
