當 Goodies 在 Ethereum Classic 鏈上提供 ETC 退款時，我如何驗證我的 The DAO 代幣餘額是否正確？
從部落格文章The White Hats and DAO Wars: 幕後，Goodies 打算：
開發智能合約，用於將 ETC 分配到區塊 1,919,999 持有 DAO 代幣的地址。

從待審核的 ETC 撤回合約中，位於 0x180826b05452ce96e157f0708c43381fee64a6b8 的DAOBalanceSnapShot合約將用於確定 DAO 代幣持有者（DTH）在硬分叉前區塊 1,919,999 的餘額。
- Daobalance 目錄，包含 dao_balance_snapshot.sol 合約和生成數據的腳本。這是從 ETH 鏈填充的，但部署在 ETC 鏈中，並包含硬分叉時的 DAO 代幣持有者余額。該合約已經部署並填充了 ETC 鏈中 0x180826b05452ce96e157f0708c43381fee64a6b8 的數據。您可以使用 geth 中的以下介面對其進行實時測試：
var daobalancesnapshot_abi =
$$ {“constant”:true,“inputs”:[],“name”:“totalSupply”,“outputs”:[{“name”:"",“type”:“uint256”}],“type”:“function”},{“constant”:false,“inputs”:[],“name”:“seal”,“outputs”:[],“type”:“function”},{“constant”:true,“inputs”:[],“name”:“totalAccounts”,“outputs”:[{“name”:"",“type”:“uint256”}],“type”:“function”},{“constant”:true,“inputs”:[{“name”:"",“type”:“address”}],“name”:“balanceOf”,“outputs”:[{“name”:"",“type”:“uint256”}],“type”:“function”},{“constant”:false,“inputs”:[{“name”:“data”,“type”:“uint256[]”}],“name”:“fill”,“outputs”:[],“type”:“function”},{“constant”:true,“inputs”:[],“name”:“owner”,“outputs”:[{“name”:"",“type”:“address”}],“type”:“function”},{“constant”:true,“inputs”:[],“name”:“sealed”,“outputs”:[{“name”:"",“type”:“bool”}],“type”:“function”},{“inputs”:[],“type”:“constructor”} $$; var daobalancesnapshot = web3.eth.contract(daobalancesnapshot_abi).at(“0x180826b05452ce96e157f0708c43381fee64a6b8”);
daobalancesnapshot.balanceOf(YOURACCOUNTHERE);

BigNumber用於準確計算totalSupply數字。檢查你的 DAO 代幣餘額
從要審查的 ETC 撤回契約中，
geth您可以使用以下命令同步到乙太坊經典鏈，檢查硬分叉前區塊 1,919,999 處的 DAO 代幣餘額：geth --fast --oppose-dao-fork console // Allow the chain to sync > var daobalancesnapshot_abi = [{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"","type":"uint256"}],"type":"function"},{"constant":false,"inputs":[],"name":"seal","outputs":[],"type":"function"},{"constant":true,"inputs":[],"name":"totalAccounts","outputs":[{"name":"","type":"uint256"}],"type":"function"},{"constant":true,"inputs":[{"name":"","type":"address"}],"name":"balanceOf","outputs":[{"name":"","type":"uint256"}],"type":"function"},{"constant":false,"inputs":[{"name":"data","type":"uint256[]"}],"name":"fill","outputs":[],"type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"name":"","type":"address"}],"type":"function"},{"constant":true,"inputs":[],"name":"sealed","outputs":[{"name":"","type":"bool"}],"type":"function"},{"inputs":[],"type":"constructor"}]; undefined > var daobalancesnapshot = web3.eth.contract(daobalancesnapshot_abi).at("0x180826b05452ce96e157f0708c43381fee64a6b8"); undefined > daobalancesnapshot.balanceOf(YOURACCOUNTHERE); 123456或者，您可以在 theDAOTokenBalance_20160819_155742UTC_balance.xlsx 中驗證區塊 1,919,999 處的 DAO 代幣餘額。您可能必須點擊滑鼠右鍵 -> 將連結另存為才能將電子表格下載到您的電腦。
檢查所有 DAO 代幣餘額
腳本getTheDAOTokenBalance查找
CreatedToken與The DAO 事件相關的所有地址，並根據 The DAO 的函式 AT 塊 1,919,999Transfer查詢每個地址。balanceOf(...)該腳本還將此結果與位於0x180826b05452ce96e157f0708c43381fee64a6b8 （此處帶有 ABI ）處的
DAOBalanceSnapShot合約進行核對，Goodies 打算使用該合約來確定每個地址在第 1,919,999 塊處擁有的 DAO 代幣的數量。結果是，與 Goodies 的合約相比，我的腳本為每個地址計算了相同數量的 The DAO 代幣，
DAOBalanceSnapShot並且總數相同。在github.com/bokkypoobah/TheDAOETCTokenBalance上有一個總結。您可以在 DAOTokenBalance_20160819_155742UTC_creation.txt 中找到所有
CreatedToken事件，在DAOTokenBalance_20160819_155742UTC_transfer.txt中找到所有事件，以及Transfer在DAOTokenBalance_20160819_155742UTC_balance.txt和 DAO_ls915742UTC_balance.txt中找到第 1,919,999塊的所有餘額。我的腳本總共找到 22,092 個非零賬戶，總共 1,153,816,598.7024671407837618 個 DAO。我的腳本查詢 Goodies 的
DAOBalanceSnapShot合約並找到相同的 DAO 總數。該DAOBalanceSnapShot合約有一個totalSupply屬性，返回值 11538165987024671407837618 或 1,153,816,598.7024671407837618 DAO。Goodies 的DAOBalanceSnapShot合約準確地表示了 DTH 在硬分叉前區塊 1,919,999 的賬戶餘額。並
totalSupply()在硬分叉前的區塊 1,919,999 處檢查 DAO，geth確認總供應量。> var theDAOABIFragment = [{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"","type":"uint256"}],"type":"function"}]; undefined > var theDAOAddress = "0xbb9bc244d798123fde783fcc1c72d3bb8c189413" undefined > var theDAO = web3.eth.contract(theDAOABIFragment).at(theDAOAddress); undefined > theDAO.totalSupply(1919999).toString(10); "11538165987024671407837618"劇本
要使用以下腳本，您必須使用
geth --oppose-dao-fork console. 請注意，您不能使用該--fast參數，因為這將排除debug.traceTransaction(...)API 查詢所需的中間結果，以確定令牌創建所涉及的正確地址。該腳本將需要半天以上的時間來執行，具體取決於您的處理器和磁碟的速度。#!/bin/sh # ------------------------------------------------------------------------------ # Retrieve The DAO Creation and Transfer events, collecting addresses.
