Hi guys,

Can anyone help me understand at a high level how writing to Ethereum differs from Bitcoin?

> Hello everyone, Multiple times the forum has discussed whether it would be possible to issue blockcerts on Ethereum. Blockcerts have always said that this would be possible, and that they are pretty blockchain agnostic. However, it hasn’t been a priority. I just want to give a little heads-up that time is changing as I’m currently in the development of adding onto the [cert-issue repo](https://github.com/blockchain-certificates/cert-issuer) to make it usable in issuing towards Ethereum. On a file level I’m looking into the following updates: [conf…](http://config.py)

Hi, there’s no smart contract involved in BlockCerts on Ethereum, too. Basically the signature is just a burn to 0xdead.
