Prominent Blockchain Explorers

As we have seen previously, blockchain explorers provide a that can query, validate, and report on transactions recorded in the blockchain. In this section we will show some of the important features available to blockchain developers.

Returning to the logs for our transactions in the Remix IDE, we can view where the contract is deployed on the blockchain.

Here we can view the transaction with which we deployed the contract. However, this is just the record for us deploying a contract, it is not the contract itself.

In order to go to our contract, we would need to copy the contract address from our deployed tab on the left side of remix selecting the copy icon next to the pin and trash icons. You'll note that in the Transaction Details view above, the "To:" address is our smart contract's address! So you can click on that directly if you want. Or do the below...

We can then paste that address into Etherscan to quickly find and navigate to that address

This is what the blockchain has recorded for our contract. In the next section we will discuss the validation of source code for contracts.
