Hello, I have a question. I want to know if someone could explain to me how blockcerts makes its connection with Ethereum. How does its connection with a node to be able to carry out transactions?  
Can I connect Blockcertes to my own node?

Hi,

we use explorer APIs such as [https://etherscan.io/](https://etherscan.io/). You can take a look at this piece of code which handles the connection: [https://github.com/blockchain-certificates/cert-issuer/blob/master/cert\_issuer/blockchain\_handlers/ethereum/connectors.py](https://github.com/blockchain-certificates/cert-issuer/blob/master/cert_issuer/blockchain_handlers/ethereum/connectors.py)

It’s been a while since I last played with Ethereum, but I believe you could use your own node, although I don’t think I can guide you on how to set this up right off the bat.

Hello,  
Blockcerts interacts with Ethereum through a process involving smart contracts and blockchain transactions. It connects to Ethereum nodes to execute transactions, such as issuing or verifying certificates on the blockchain. You can connect Blockcerts to your own Ethereum node by configuring it to interact with your node’s API endpoints. This allows you to manage transactions and data directly through your node, providing flexibility and control over how Blockcerts interacts with the Ethereum network.
