我們已經(jīng)創(chuàng)建過一個回復消息的機器人和一個能自動支付比特幣的機器人.

如何創(chuàng)建一個比特幣錢包.

如何讀取比特幣錢包的余額.

如何支付比特幣并即時確認.

如何將Mixin Network的比特幣提現(xiàn)到你的冷錢包或第三方交易所.

前期準備：你要有一個Mixin Network賬戶。下面的代碼創(chuàng)建一個帳號，并寫到csv文件里。

if File.file?(WALLET_NAME)
  p "mybitcoin_wallet.csv has already existed !"
  next
end
yaml_hash = YAML.load_file("./config.yml")

MixinBot.client_id  = yaml_hash["MIXIN_CLIENT_ID"]
MixinBot.session_id = yaml_hash["MIXIN_SESSION_ID"]
MixinBot.client_secret = yaml_hash["MIXIN_CLIENT_SECRET"]
MixinBot.pin_token   = yaml_hash["MIXIN_PIN_TOKEN"]
MixinBot.private_key = yaml_hash["MIXIN_PRIVATE_KEY"]

access_token = MixinBot.api.access_token("GET","/","")

rsa_key = OpenSSL::PKey::RSA.new(1024)
private_key = rsa_key.to_pem()
p private_key
public_key = rsa_key.public_key.to_pem
secret_client = public_key.sub("-----BEGIN PUBLIC KEY-----
","").sub("
-----END PUBLIC KEY-----
","")
reqInfo = MixinBot.api.create_user("ruby bot",secret_client)
p reqInfo["data"]["pin_token"]
p reqInfo["data"]["user_id"]
p reqInfo["data"]["session_id"]


CSV.open(WALLET_NAME, "wb") do |csv|
  csv << [private_key, reqInfo["data"]["pin_token"], reqInfo["data"]["session_id"], reqInfo["data"]["user_id"]]
end

上面的語句會在本地創(chuàng)建一個RSA密鑰對，然后調用Mixin Network來創(chuàng)建帳號，最后保存帳號信息到csv文件.

現(xiàn)在你需要小心保管好你的帳號信息，在讀取該賬戶的比特幣資產(chǎn)余額或者進行其他操作時，將需要用到這些信息.

新賬號并不默認內(nèi)置比特幣錢包， 現(xiàn)在讀一下比特幣余額就可以創(chuàng)建一個比特幣錢包。

if cmd == "2"
  table = CSV.read(WALLET_NAME)
  MixinBot.client_id = table[0][3]
  MixinBot.session_id = table[0][2]
  MixinBot.pin_token = table[0][1]
  MixinBot.private_key = table[0][0]
  botAssetsInfo = MixinBot.api.read_asset(BTC_ASSET_ID)
  p botAssetsInfo
  p "The BTC wallet address is " + botAssetsInfo["data"]["public_key"]
  p "The BTC wallet balance is " + botAssetsInfo["data"]["balance"]
end

創(chuàng)建的帳號的比特幣資產(chǎn)詳細信息如下，其中public key就是比特幣的存幣地址:

 "confirmations"=>6, "capitalization"=>0}}
"The BTC wallet address is 1MQLQG1FshdVaQrDE36FLGabCitE3vPUA"
"The BTC wallet balance is 0"
-------------------------------------------------------------------------

這個API能夠提供若干與比特幣有關的信息:

存幣地址:[public_key]

Logo: [icon_url]

資產(chǎn)名字:[name]

資產(chǎn)在Mixin Network的uuid: [asset_key]

對美元的價格(Coinmarketcap.com提供): [price_usd]

存幣時確認的區(qū)塊數(shù)量:[confirmations]

比特幣的私鑰呢？這個私鑰被Mixin Network通過多重簽名保護，所以對用戶來說是不可見的,比特幣資產(chǎn)的提現(xiàn)和轉賬都需要用戶提供正確的的RSA簽名,PIN代碼與會話密鑰才能完成.

這個帳號不只支持比特幣，還支持以太坊，EOS等, 完整的區(qū)塊鏈支持列表. 這個賬戶同時也支持所有的 ERC20 代幣與 EOS 代幣.

創(chuàng)建其它的幣的錢包與創(chuàng)建比特幣錢包過程一樣，讀對應的資產(chǎn)余額就可以.

EOS的存幣地址與其它的幣有些不同，它由兩部分組成： account_name and account tag, 如果你向Mixin Network存入EOS，你需要填兩項數(shù)據(jù)： account name 是eoswithmixin,備注里輸入你的account_tag,比如0aa2b00fad2c69059ca1b50de2b45569.

EOS的資產(chǎn)余額返回結果如下:

   "confirmations"=>64, "capitalization"=>0}}
"The EOS wallet address is eoswithmixin 60ec682616408d9486b5975a1361e269"
"The EOS wallet balance is 0"
-------------------------------------------------------------------------

現(xiàn)在，你可以向比特幣的錢包存幣了。

當然，在比特幣網(wǎng)絡里轉幣，手續(xù)費是相當貴的，費用的中位數(shù)在0.001BTC,按當前4000美元的價格，在4美元左右，有一個方便的辦法，如果你有Mixin Messenger帳號，里面并且有比特幣的話，可以直接提現(xiàn)比特幣到新創(chuàng)建的帳號的比特幣充值地址，它們在同一個Mixin Network網(wǎng)絡內(nèi)，手續(xù)費為0，而且1秒到賬。

下面的代碼，可以讀取比特幣錢包余額.

table = CSV.read(WALLET_NAME)
MixinBot.client_id = table[0][3]
MixinBot.session_id = table[0][2]
MixinBot.pin_token = table[0][1]
MixinBot.private_key = table[0][0]
botAssetsInfo = MixinBot.api.read_asset(BTC_ASSET_ID)
p botAssetsInfo
p "The BTC wallet address is " + botAssetsInfo["data"]["public_key"]
p "The BTC wallet balance is " + botAssetsInfo["data"]["balance"]

任何幣在Mixin Network內(nèi)部的交易，都是無手續(xù)費的，并且立刻到賬。
前期準備： 賬戶設置了PIN

對于新創(chuàng)建的帳號，我們通過updatePin來設置新PIN碼, 代碼如下：

table = CSV.read(WALLET_NAME)
puts table[0][1]
MixinBot.client_id = table[0][3]
MixinBot.session_id = table[0][2]
MixinBot.pin_token = table[0][1]
MixinBot.private_key = table[0][0]
pinInfo = MixinBot.api.update_pin("",DEFAULT_PIN)
p pinInfo

通過Mixin Messenger，我們可以先轉比特幣給機器人，然后讓機器人轉幣給新用戶。

if cmd == "teb"
  yaml_hash = YAML.load_file("./config.yml")

  MixinBot.client_id  = yaml_hash["MIXIN_CLIENT_ID"]
  MixinBot.session_id = yaml_hash["MIXIN_SESSION_ID"]
  MixinBot.client_secret = yaml_hash["MIXIN_CLIENT_SECRET"]
  MixinBot.pin_token   = yaml_hash["MIXIN_PIN_TOKEN"]
  MixinBot.private_key = yaml_hash["MIXIN_PRIVATE_KEY"]
  table = CSV.read(WALLET_NAME)
  wallet_userid = table[0][3]
  botAssetsInfo = MixinBot.api.read_asset(EOS_ASSET_ID)
  if botAssetsInfo["data"]["balance"].to_f > 0
    transInfo = MixinBot.api.create_transfer(MixinBot.api.encrypt_pin(yaml_hash["MIXIN_PIN_CODE"]),
                                      {
                                        asset_id: EOS_ASSET_ID,
                                        opponent_id: wallet_userid,
                                        amount: botAssetsInfo["data"]["balance"],
                                        trace_id: SecureRandom.uuid,
                                        memo: "from ruby"
                                      })
    p transInfo
 end
end

讀取Bitcoin的余額，來確認比特幣是不是轉成功了！

    botAssetsInfo = MixinBot.api.read_assets()

如果你希望將幣存入你的冷錢包或者第三方交易所, 先要得到冷錢包或者你在第三方交易所的錢包地址，然后將錢包地址提交到Mixin Network.

要點提示: 提現(xiàn)是需要支付收續(xù)費的,準備好比特幣包地址!

調用createAddress API, 將會返回一個address_id,下一步的提現(xiàn)操作會用到這個id。

if cmd == "wb"
  table = CSV.read(WALLET_NAME)
  MixinBot.client_id = table[0][3]
  MixinBot.session_id = table[0][2]
  MixinBot.pin_token = table[0][1]
  MixinBot.private_key = table[0][0]
  addressInfo = MixinBot.api.create_withdraw_address(BTC_ASSET_ID,
                                                       DEFAULT_PIN,
                                                       BTC_WALLET_ADDR,
                                                       "","",
                                                       "from ruby")
  p addressInfo
  p "The address id is " + addressInfo["data"]["address_id"] + " it is needed by read fee!"
end

這里的 14T129GTbXXPGXXvZzVaNLRFPeHXD1C25C 就是一個比特幣錢包地址, 如下所示，提現(xiàn)費用是0.0025738 BTC, address_id 是"345855b5-56a5-4f3b-ba9e-d99601ef86c1".

  addressInfo = MixinBot.api.get_withdraw_address(addressInfo["data"]["address_id"])
  p addressInfo

提交提現(xiàn)請求到 Mixin Network, withdrawAddress.address_id 就是createAddress創(chuàng)建的。

if cmd == "wb"
  table = CSV.read(WALLET_NAME)
  MixinBot.client_id = table[0][3]
  MixinBot.session_id = table[0][2]
  MixinBot.pin_token = table[0][1]
  MixinBot.private_key = table[0][0]
  addressInfo = MixinBot.api.create_withdraw_address(BTC_ASSET_ID,
                                                       DEFAULT_PIN,
                                                       BTC_WALLET_ADDR,
                                                       "","",
                                                       "from ruby")
  p addressInfo
  p "The address id is " + addressInfo["data"]["address_id"] + " it is needed by read fee!"
  addressInfo2 = MixinBot.api.del_withdraw_address(addressInfo["data"]["address_id"], DEFAULT_PIN)
  p addressInfo2

  withdrawInfo = MixinBot.api.withdrawals(addressInfo["data"]["address_id"],
                                          DEFAULT_PIN,
                                          "0.1",
                                          SecureRandom.uuid,"from ruby")
  p withdrawInfo
end
