TotalOutput Value in Cardano

I am not sure this is the right place to ask this but I could not find anywhere else.
Looking at epoch 316 details on CardanoScan (Epoch 316 - Cardanoscan) and I see that the Total Output value has 53B ADA.
What does this field mean? How is it greater than the total supply of ADA?

Hello @tigoni

Some data aggregators collect info on all outgoing Tx. Since Cardano is UTxO based model any time you make a transaction all UTxOs involved in that transaction “leave” and change given back to your wallet is labeled as TxOUT…

For example:
If you have 100 ADA in your wallet and you send 1 ADA to someone it will show Output as 1 ADA to new wallet and 99 ADA back to your own wallet. This by some data aggregators is counted as 100 ADA transaction.

Some data aggregators filler out all transactions that put change back into your wallet. For example:
Adastat filters for change and shows just over 6 Billion for Epoch 316.

There is no standard by which they all display and sort block info, so you have to look into exactly what they consider transaction and/or outgoing transaction.

I recommend to always look at the few sources, so you can narrow down exactly what type of data you are looking for.


Hello @Neo_Spank That makes sense now. Would it be correct to say this metric is specific to a UTXO based ledger and would no make sense on an account based one where balances are updated for transactions?

Thanks for the link. It definitely has more refined data overall.

It’s more of a case of how each data service represents given data.

It is true that UTxO has Tx outputs for change back to the wallet, but any metric has only the meaning that data service provider gives it. There are no set standards that would make a metric shown on one site be specific to anything on any other sites.

Even if the network under consideration would not be UTxO, the total output could still be higher than the total number of coins in existence. One coin can circulate many times in a given period.
