I have the 2020 .dat backed up in multipe locations so not to worried about anything happening this copy of a backup. 

I am now wondering can i just make a new backup of the wallet from core 27.1.0 and that will be it sorted.

Thanks

Just loaded an old Core backup from 2020 and was informed about migration in version 27.1.0, is this something i need to do soon?  it talked about legacy wallets, but all the addresses in the backup are bc1q, native segwit addressess.  Anything i should be concerned about or is it pretty straight forward?

Thanks

Thanks for all the replies, particularly from nc50lc.  As always a cool came reply.  Thanks

I am about to do an IBD and i have assumevalid=(Latest block). i understand some of the risks involved with this, regarding being feed a false history etc:  But if i don't plan to use the node to validate transactions for a long time 6 month min then i am assuming that my node will eventually check all blocks thoroughly and so its fine. 

Thanks

This is correct, I renamed the old, locked "chainstate" folder to "chain" then ran bitcoind -reindex.  Bitcoin core created a new chainstate folder,  until that point, --reindex/--reindex-chainstate wouldnt work.

***UPDATE**** Renaming the Chainstate folder seems to have worked, currently reindexing.  Thanks will let ya know if it has further issues.

PC Crashed yesterday due to a graphics error, nothing to do with Bitcoin core.  went to run core again today but getting this error below.  I had a look in the Chainstate folder and all files are locked by Microsoft Access, any ideas on how to resolve this? 

also tried running with arg -reindex but still error.

Thanks

Many thanks for the replies always great to get help here.  I ended up putting the multisig backup into Sparrow wallet and it worked first time, it found the jade and just used it to sign.  i will play around and getting it working on Electrum for the learning.   

Thanks again

Yes this is right.  The Ledger I originally used has shit itself and i don't want to buy another Ledger.  So when i connect my HW to Electrum it is asking for the fingerprint of the Ledger.  There is bound to be away around this, nc50lc hs given me an idea, i will let yous know how it works.  Thanks for the replies.

---

So i just cut and paste the 3 Zpubs into a new electrum 2of3 and it recognized the previous transactions.  however, when i went to send it doesn't give me the option to sign.  I get it, electrum doesn't know anything about the HWs now, any ideas on how to work this out?

so in the Preview pay page, the sign button is greyed out. There must be a way to initialise the HWs?

[moderator's note: consecutive posts merged]

So i have a 2 of 3 setup using a trezor, jade and a ledger.  I recently put the seed words for the ledger onto a jade HW and tried to use it to sign a transaction as if it were from the ledger.

 Electrum is looking for the ledger bip32 root fingerprint, so even tho the seed is the same but is on a jade. is there a way to get Electrum to recognize the jade as the ledger?

So trying to verify 24.0 but using Kleopatra I keep getting a "signatures could not be verified" message.  I am guessing this is because I need at least one of the builder keys from the github key list.  But when I try to import one of them using this

gpg.exe --keyserver hkps://keys.openpgp.org --recv-keys E463A93F5F3117EEDE6C7316BD02942421F4889F

I keep on getting "keyserver receive failed: Certificate expired" message, which surely can't be right, what am I doing wrong here. 

Thanks got it..... 

When verifying the latest Bitcoin core software I get this below.  i am sure its probably fine but it just doesn't look right "Can't check signature: No public key".  what am I doing wrong?

Thanks for the replies guys.  I think I'm getting the vibe that this isn't a great idea.  it is at a physical meetup and there is prob a lot that could go wrong over time.  Appreciate the replies as always. 

Hi all, me and a couple of bitcoiners have been considering running a coinjoin thing at our local meetup, but are wondering if it is even worth doing?  i haven't really gamed it out in my head yet, just thought I would come on here and have you guys blow holes in it quickly if it's stupid.  fire away.

roughly 10- 20 participants with 0.01 btc

NO others, (including clearnet nodes) can connect to a Tor node.

The best why to support the Bitcoin network is to buy and hold bitcoin.  self custody it and use your own Node to verify you received it. 

Anything replacing Bitcoin would destroy the store of value thesis which is a fundamental of money, this would be game over.  I dont believe it will ever happen as the market is not that stupid. 

Most people who ask or believe it are basically hoping their bags will be the one to do it.  If your altcoin could do it then what would stop your alt being replaced in 10 years by another.....? ie: Store of value would be dead.

Doh, im an idiot sorry ........ 

I currently have Core 0.20.1 , but i just checked both the post by AChow on this site and the bitcoincore.org and they say the latest is 0.20.0   

Thanks for the replies.  will try adding bind=127.0.0.1 and see, i know it can take awhile to be found. 

Cheers
