Updates for this month’s roadmap update were:

  • Paper Wallets will see a first version released shortly.
  • Daedalus Wallet Accounts and Multi-currency Ledger are two new roadmap items.
  • Stake pool testnet registration has been extended until the end of May - to give more opportunity for interested parties to register their interest. IOHK have received over 1500 applications and have been pleasantly overwhelmed by the great level of interest.

Community questions

This week’s question comes from a Japanese community member who contacted us through our Help Centre on how to read the information displayed under a transaction in the Cardano Block Explorer.

Firstly, what is a Block Explorer? A Block Explorer allows anyone to search addresses, transactions, epochs and slots that have taken place on a blockchain. IOHK have built a block explorer specifically for Cardano allowing anyone who wishes to search transactions and check wallet balances.

Now, to get back to the question, let’s take for an example this transaction:

unnamed

Every transaction has an ID, and it is unique on the blockchain. On the left hand side, where you see 3 addresses, you will find the inputs. These lead into the 2 output addresses. One output address is the receiver address and the other is the “change address”, where the remaining Ada from the input addresses goes back to the sender’s wallet.

As for the input, you will sometimes see multiple addresses listed. This is because your wallet is a collection of addresses (in unspent transaction outputs or UTxO) which hold Ada and out of which, you can spend or send funds from. The wallet will choose inputs when you make a transaction.

For example:

Address 1: 1 Ada

Address 2: 10 Ada

Address 3: 100 Ada

If you want to send 105 Ada, your wallet would choose address 2 and 3 as inputs and send back 5 Ada to your change address. That is why transactions need multiple inputs.

The values on the rightmost side correlate with amounts of the inputs.
