如何使用比特幣-盧比廣播原始交易？ 我使用了https://github.com/lian/bitcoin-ruby的 bitcoin-ruby gem

    Bitcoin.network = :testnet

    address="muLGqMS6tkqb9sBQ4sqeXjMzaV8rk8o3gv"

    url = "https://testnet.blockexplorer.com/api/addr/#{address}"
    uri = URI(url)
    response = Net::HTTP.get(uri)
    if Connect.valid_json(response)
      response = JSON.parse(response)
      $transactions = response["transactions"]
    end

    prev_hash = $transactions[0]

    url = "https://testnet.blockexplorer.com/api/rawtx/#{prev_hash}"
    uri = URI(url)
    response = Net::HTTP.get(uri)
    if Connect.valid_json(response)
      response = JSON.parse(response)
      response = response['rawtx'].to_s
      $prev_tx = Bitcoin::P::Tx.new(response.htb)
    end

    prev_tx = $prev_tx
    prev_tx_output_index = 0
    value = 50000 #0.0005 btc

    tx = Bitcoin::Protocol::Tx.new
    tx.add_in Bitcoin::Protocol::TxIn.new(prev_tx.binary_hash, prev_tx_output_index, 0)

    tx.add_out Bitcoin::Protocol::TxOut.value_to_address(value, "msPHTrHSktDLMwPXcMYwWTqth3ZyykN17H") # <- dest address (our donation address)

    # if all in and outputs are defined, start signing inputs.
    key = Bitcoin.open_key(Connect.get_private_key) # <- privkey
    sig = Bitcoin.sign_data(key, tx.signature_hash_for_input(0, prev_tx))
    tx.in[0].script_sig = Bitcoin::Script.to_signature_pubkey_script(sig, [key.public_key_hex].pack("H*"))
    #tx.in[0].add_signature_pubkey_script(sig, key.public_key_hex)

    # finish check
    tx = Bitcoin::Protocol::Tx.new( tx.to_payload )
    p tx.verify_input_signature(0, prev_tx) == true
    hex =  tx.to_payload.unpack("H*")[0] # hex binary
    puts hex.to_s
#Error sending transaction: Transaction 4a762238529450737b85ad481deae0e836e623afd63e04a29a5b90363c0345fd has too high fees: 12372992.

Answer 1

交易費用只是輸入值與輸出值之差。 在這種情況下，您的輸出值為0.0005 BTC。 如果您選擇的輸入大於要發送的輸出以及費用，則必須創建一個更改輸出以將其余的也發送回您的錢包，否則將全部作為費用發送給礦工。 例如，如果您輸入的是0.25 BTC，而您想發送0.15 BTC且僅支付0.01 BTC費用，則您的交易將需要有兩個輸出，一個為0.15 BTC，一個為0.09 BTC，返回到您擁有的地址，因此總費用僅為（0.25-（0.15 + 0.9）= 0.01）

您可以使用sibit ，這是我的Ruby gem：

require 'sibit'
sibit = Sibit.new
pkey = sibit.generate
address = sibit.create(pkey)
balance = sibit.balance(address)
target = sibit.create(pkey) # where to send coins to
change = sibit.create(pkey) # where the change will sent to
tx = sibit.pay(pkey, 10_000_000, 'XL', [address], target, change)
