Daedalus size growth ... what is the plan?

As the chain keeps growing, Daedalus Mainnet keeps taking up more space. At the time of writing, the associated Application Support folder on MacOS is almost 60 Gb. Users (like me) don’t have infinite harddrive space and will eventually flee to Yoroi, reducing the number of nodes in the network.

What is the plan? Short term and long term? Will there eventually be an option to run a node without storing all data locally, or is that technically infeasible?

All the best

It doesn’t matter. The Daedalus nodes do nothing good for the network. They are not needed. They don’t have any incoming connections from others. They just connect to IOHK nodes.

But I would not flee for Yoroi, but for one of the other, better light wallets.

It should be feasible and it should definitely come.

But as far as I have heard, IOG is busy with their light wallet and other things.


Daedalus light wallet; should be released soon.


This week, the Daedalus team added support for Ledger Nano S Plus, which will be delivered in the subsequent release. The team also made progress on the native Daedalus M1 development - the first superficial tests ran smoothly on M1-Mac. Finally, the team continued building a bridge between cardano-wallet and light-wallet.

The Adrestia team released an important update for cardano-wallet. The update accumulates a series of changes and improvements developed over the past few weeks.

They also continued working on adding multisig features, redesigning the DB layer, and developing a “light” mode in cardano-wallet.

Finally, the team is still working on the cardano-js-sdk MVP.

Daedalus hasn’t really been all that user friendly since inception. See all the various workarounds attempted well over a year ago for various issues. It has not improved. Perhaps not ironically the third party wallet applications have now set the bar for Cardano whereas Daedalus and Yoroi simply do not cut the mustard anymore. However that is what community is about!

Thanks for all the replies. Very insightful.

If I understand correctly, the sole purpose of keeping the entire chain on your drive is trustless validation, not expanding the network (as I believed). Daedalus in the upcoming “light mode” would then off-load this trust to third party servers, thereby loosing this trustless mechanism. Is this not a defat for decentralisation? Is there not a smarter way to perform trustless validation in a decentralised manner (not relying on a single third party server keeping the entire chain)? Or will a decentralised solution simply be too slow?

You could, I think, quite easily only verify the blockchain once and just save “Up to this block with this signature leading to this UTxO set everything was okay.”, but throw away the blocks afterwards and not let them clutter your disk. This verification would still take days as it does now with Daedalus, but it would at least not eat so much storage, anymore.

Logical next step would be that you can save (and maybe sign) such snapshots, so that you do not have to do it again on every machine, after every reinstallation, but can just reuse it.

But then, these snapshots could also be provided by other nodes that you trust.

Yes, that would be a little less “trustless”, but the current workings are also not that “trustless”. Daedalus only connects to the nodes of a single company. They already could deliver you a wrong history. They almost surely do not. It would have led to lots of problems, when doing transactions with the rest of the network, and someone™ would have noticed, but it’s still not as “trustless” as advertised. And if I trust them in giving me the correct history if I query it block by block, why shouldn’t I trust them to give me a correct snapshot and spare my computer the pointless exercise of doing the same calculations again and again?

I would think that a better layout would be that most nodes in the network – Daedalus-like wallet apps, relays, block producers – only store such a reduced current state of the chain, which is enough to do verification of transactions and new blocks, and only a much smaller, but still decentralised amount of archive nodes stores the whole history and provides it to everyone interested.

By the way: That is more or less, what Bitcoin is doing for years: https://bitcoin.stackexchange.com/a/92015 The more than 300 GiB that their blockchain already has would be too much for many. And even pruning full nodes are still considered full nodes with them.

Daedalus has improved a ton since inception. It can actually do way more things than it used to for me.

“light mode” for Daedalus, aka Mithril doesn’t offload trust to 3rd party servers. It’s relying on signed snapshots to allow faster usage.
