Cardano Node not Syncing

[Rozaelli]

Hello Cardano Community,

I downloaded Daedalus a few weeks ago, and was able to access my wallet for the first day. After that, I was not able to access my wallet. The cardano node will not respond and it will not sync. When I open Daedalus, it says "Verifying the blockchain 99.9% but it never fully loads.

What should I do?

So far I have tried reinstalling daedalus and downloading logs (though I don’t know if I did that right)

Workaround to fix Daedalus "connecting to network" and syncing issue

Hi! By default Daedalus wallet tries to connect to IOG relay servers - relays-new.cardano-mainnet.iohk.io Sometimes this connections attempt could take for a while and once it is established the synchronization of the blockchain could be slow as well. So a workaround can be to change the relay server address to any other public relay address available on the decentralized network. Daedalus wallet actually a passive node on the network which can connect to several relay nodes. More info about…

Hi!

btw, what is the RAM size of your system?

Daedalus: Relay Node Configuration Help?

Anyone else notice that Daedalus 4.0.4 sync was immeasurably faster than 4.0.5? Anyone know why and what to do about it? On a few machines I installed a fresh copy of 4.0.4 and it was good to go in about an hour on gigabit hardwired. Laptop took somewhat longer over 5G but that is to be expected of wireless. Updating from 4.0.4 to 4.0.5 was fine but sync on even a few days of datas seemed about as long as the initial which baffled me. Out of curiosity I did a fresh install of 4.0.5 and fired i…

[SOLVED] Daedalus wallet appears stuck on «Connecting to network»

@raph_cardano script will actually work better even though it takes a bit longer to run as it measures the response time of each node and sorts by the fastest nodes found! Mine just filters by available nodes nearest to you but you have to follow the TODO instructions in the code to setup your preferred location as it’s very basic. You should only need to run either of these “configuration helper” scripts once anyway. @Crypto_Dryp below is the general steps for using either Python script for ne…

Hopefully as the blockchain gets bigger and more users adopt Cardano they will address some of these performance issues. For now here are the REAL system requirements for Daedalus according to my experimentation on 4 different computers.

16+ GB RAM
With 8GB or less OS will hit swap space or virtual memory and bring your entire machine to it’s knees or crash as the Cardano node takes 4-8 GB due to memory leaks and bugs

4+ physical core CPU
The verification process and running the node will thrash all CPUs even on a 9th gen i7! Again performance bugs and issues with the Cardano node

25+ GB free disk space
The blockchain is about 12GB as of epoch 273 today, the Daedalus app itself will take another 1.5GB, you need room to grow!
