This may sound a naively simple question, but...

  1. How big is the blockchian today?

  2. How big is it likely to become in future?

I note that Daedalus' state directory on my machine is currently ~10.3G.

Is it correct then to say that that's the "size of the chain" today?

For the second question, we could hypothesize a number of scenarios, like: 5 million Digital Identities are issued. What impact is that likely to have on storage requirements of Daedalus?


It's hard to tell how the network will grow into the future because of both varying usage and IOHK introducing new chain optimisations etc.. However we can work out the hypothetical maximum growth using the current chain parameters.

Max_Block_Size = 65536 bytes
Blocks_Per_Epoch = ~21000 
Epoch_Length = 5 days

So we could say a rough maximum chain size increase over an Epoch is Max_Block_Size * Blocks_Per_Epoch which comes out as 1.4155776 GB per epoch or around 100 GB per year.


I'm only answering about the size for now: on one of the cardano nodes that I just checked some seconds ago

$ du -sh state-node-mainnet

I can't say how fast it grows. I just look at it from time to time.

    That is your size containing all the forks probably. Fresh sync of the mainnet is somewhere around 8.5GB. May 4 at 8:46
