Solidity: Burn event vs Transfer to 0 address

Question

I've seen the Burn event be represented as:

• Burn(burner, _value); in OpenZeppelin's BurnableToken
• Transfer(_owner, 0, _amount); in Giveth's MiniMeToken

Are both of these ways correct? Is one of these ways better than the other?

Answer 1

The ERC 20 standard doesn't mention burning specifically, as far as I can see. It does, however, specify the Transfer event as:

event Transfer(address indexed _from, address indexed _to, uint256 _value)

So to be compatible with any software that meets the standard, Transfer is what you want.
