After I upgraded zcash to v5.1.0, it has started rescanning a week. At Last I found the progress is moving backward.
Is there any way to this problem?Thanks.

Due to the recent increase in transaction outputs, blocks are harder to validate. In fact, they are being produced faster than your machine can check them. Unless the situation changes, you will not catch up, unfortunately.

With the following change in the v5.2.0 release, wallet scanning performance will see significant improvements:

Aaaaannnd it’s gone.

I just want to transfer coin from my old wallet. But if I do not rescan the blockchain, I can’t make it.
Is there any solution to solve it? Thank you for your reply.

Thank you for your reply.
I just want to transfer coin from my old wallet. There is no any estimated time for v5.2.0 release, but I need solve it as soon as possible. I have tried a lot of methods like starting a new node to import the backup wallet, but no one works. I really don’t know what to do next.

Your best bet is to export your private key and import it into a light wallet such as ZecWallet Light or YWallet.

Out of curiosity, what CPU does your computer have?

I look forward to the release of this hoping it fixes the issue for me aswell. Hopefully fingers crossed it is not to far away

Hey hanh, i have tried using both y wallet and zecwallet light both do not work for me. I tried both mobile and desktop.
Ywallet in particular accepts my keys and syncs no problems, though once the sync is finished my wallet or funds do not appear, i have tried changing the servers and also done multiple rescans. Not sure if it matters but all my coins are in one T address

But doesn’t the log file go from top to bottom?

If you are using a key that begins with secret-main, it is a z addr key.

I would guess these issues are more likely to be memory related. With Windows you can allocate a readyboost partition somewhere like on a quality, high speed SD card or flash drive and will work most of the time for ram bottlenecks. On Linux it’s a swap file and you can adjust what’s called swapiness. Idk if you can on Windows but typically it seems it gets used a lot.

8 Core and 64G Memory.

Oic there at the bottom, ok sry

yes,the rescan can’t keep up with the new block speed. So the progress is moving backward.

Do you have a SSD?

v5.2.0-rc1 has synced much faster for me. Will need to compile yourself or wait for the official release but excited improvements are coming :zebra:

I’m running two 5.1.0 nodes, on one an i5 mesa 1.7ghz x8 with 8GB and one on a Xeon 2.8ghz x8 with 12GB. Both are on HDDs which I didn’t consider before but both are using 3.7 GB and my cpus aren’t throttling much at all. Zcashd spawns like 20 something processes under zc-wait-to-stop but it’s incuring like 20% max per single thread at any one time while the other threads are 0-5% most commonly. The Xeon is even less noticable usage. The Network up and down gets wild but thats normal I think. Mostly it’s just a spike for a second then pretty low usage.
