燃燒乙太幣和其他乙太坊代幣的最佳方式？

發送到地址 0x0000000000000000000000000000000000000000 的任何乙太幣或代幣都將被銷毀，這是否正確？

或者燃燒乙太幣/代幣的最佳方式是什麼？

根據 Jeff Wilcke的說法，銷毀 ETH 的正確方法是創建一個合約，該合約會立即自毀並發送到自己的地址，或者只是將乙太幣發送到他部署的合約，這一切都會為你完成：

https://etherscan.io/address/0xb69fba56b2e67e7dda61c8aa057886a8d1468575#code

這是程式碼：

pragma solidity ^0.4.11;

contract Burner {
   uint256 public totalBurned;

   function Purge() public {
       // the caller of purge action receives 0.01% out of the
       // current balance.
       msg.sender.transfer(this.balance / 1000);
       assembly {
           mstore(0, 0x30ff)
           // transfer all funds to a new contract that will selfdestruct
           // and destroy all ether in the process.
           create(balance(address), 30, 2)
           pop
       }
   }

   function Burn() payable {
       totalBurned += msg.value;
   }
}

一個沒有組裝的更簡單的例子是：

contract GetsBurned {

   function () payable {
   }

   function BurnMe () {
       // Selfdestruct and send eth to self, 
       selfdestruct(address(this));
   }
}

呼叫BurnMe第二個範例後，您會看到合約的地址不再有任何餘額或程式碼。ETH 就這樣消失了！

如果您只需要銷毀在乙太坊平台上開發的代幣，則可以將此功能嵌入到智能合約本身中：

/**
* @dev Burns a specific amount of tokens.
* @param _value The amount of token to be burned.
*/
function burn(uint256 _value) public {
   require(_value > 0);
   require(_value <= balances[msg.sender]);
   // no need to require value <= totalSupply, since that would imply the
   // sender's balance is greater than the totalSupply, which *should* be an assertion failure

   address burner = msg.sender;
   balances[burner] = balances[burner].sub(_value);
   totalSupply = totalSupply.sub(_value);
   Burn(burner, _value);
}

如果您開發自己的集中式令牌，您可能希望嵌入一些額外的安全檢查，例如驗證函式呼叫者的地址。
