Did you read the very first result on that search?

Not getting into this discussion, but a slight reminder - Google can and does serve different search results to different people (or even different browsers on the same computer).

  Both good points. ERC20 token should be indistinguishable from each other because it's a standard devised precisely to encourage and facilitate trading.

  I know and I deliberately put a google search query instead of a specific link, because I read all the google links and this cannot be done decentrally.

Please link me up, I have checked and tried more than 20 results and none of them tell why or work.

The short answer is that you need the contract code and ABI to check if it is a ERC20 compliant token or not but you can use http://testnet.etherscan.io/ http://testnet.etherscan.io/ (or the live version) to get this information.

    So manual then? To reach the ethereum genesis block programatically, starting from an erc20 token I give you, you need that "need the contract code" part which is centralised.

      There is a difference between tokens and the currency Ether so I'm not sure what you mean with the genesis block in regards to ERC20 tokens here. The contract that holds the ERC20 is hosted in every single node of the blockchain so it is not centralised at all.
