Hey everyone, do we need to backup our DVC wallet after each transaction or is it enough to only do it once?

I think once is OK. However, do as many backups as you can. You can't have enough backups of something.  I recently lost a lot of stuff from my old HDD because I didn't have a backup for it. Fortunately, I got my DVC wallet stored in several places. So, do it once, but store it in several safe places.

The wallet generates I think 100 addresses when it is created, then as it runs low it generates more; and there is a command to make it generate more too so if you expect to use a lot before your next backup you can deliberately generate a lot so your backup will contain the next however many addresses that will be used.

So you have some leeway.

When you send coins often an address will be used up to send the change to, and of course every time you do getnewaddress to get a new address to tell someone to send to that uses up one of the pre-created addresses.

So basically every time you do a backup it includes the next X-number of addresses that are to be used.

Once they have all been used, you will be into new territory, using addresses that had not been created at the time of your last backup.

So the key is to make backups faster than you use up addresses.

For example if you have a website that lets visitors cause an address to be created for them to send coins to, and thousands of visitors get addresses created daily, or one visitor uses a bot to have it generate tens or hundreds of thousands of addresses for them in one day, you might be hard-pressed to make backups often enough, and will want to generate vast numbers of addresses ahead of time to back up before the site gives them out.

If on the other hand you only have one publicised address for folks to send you coins (a donation address for example, or the address DevTome sends your shares to), and never send coins so never use up addresses to send change to, then one backup will last you "forever" with plenty of pre-generated addresses in it ready for some day when you do suddenly need another address or few.

Is that sort of a description of "coin mixing" and issuing lots?

I have experienced the same on my windows laptop.

I added all the nodes from https://chainz.cryptoid.info/dvc/#!network which is reading a block height count of 369636

But this also got stuck again at block 359999.

I can try adding in manually the receiver file tonight to see if that makes a difference, but I am hosting the receiver files myself and they should be downloadable so not sure if that is the issue.  Has anything changed in the code? do we need to issue new binaries  off the new build?  I can try a linux build this week if I get some time, and will also have a look at the mac build I have been trying to get round to looking into.

ok so i got the blockchain downloading again past block 359999 (10 weeks behind) by manually downloading the receiver file 90 and starting devcoin client.

direct download can be done here: http://galaxies.mygamesonline.org/receiver_90.csv or here: http://devcoinpool.btc-music.com/receiver/receiver_90.csv

blockchain fully synced after dropping the receiver files.

Any questions or issues please let me know.

I'm having wallet issues now too. I got beyond the point you did, FuzzyBear, but got stuck further down--block 36999 or something. So I tried to manually download receiver 91 (replaced what was in my folder with one I downloaded from the direct download site (only changed to be receiver 91). The next time I ran my wallet, I got the "failed to connect to best block" error message. So I thought, great, I've corrupted the block chain. I deleted all but wallet.dat and tried again. It won't get past block zero now. I tried to shut down wallet and restart. That gave me the failed to connect error message again. Deleted everything, trying again, stuck on block zero (for now). I'm going to walk away and come back (and if it starts syncing I'll post an update). If it stays stuck on block zero, what are the steps I can take to get my wallet working again?

Edit: It's also stuck on only one active connection to network.

Edit: I restored the original peers file to see if that would help. My wallet now has 2 active connections and is still stuck on block zero. I'm running out of ideas. Please help.

Edit: 4 active connections now. still stuck on block 0. Maybe it's just slow?

My wallet is up to 11 active connections and still stuck on block zero. I've worked with a lot of QT wallets but this is a new wrinkle for me. What do I do?

create a devcoin.conf  in it
and paste the following:

rpcuser=username
rpcpassword=password

So I did this and the wallet very quickly made 8 connections with the devcoin network. So far (after about 5 minutes) it is still stuck on block 0, though. I'll let it run for an hour or two and post if it starts downloading blocks. If it doesn't download blocks, do you have any other suggestions? Thanks!

mine stopped getting blocks at some point so again,i looked for ways to fix it

https://codeload.github.com/devcoin/receivers/zip/master
download the recievers from the coin's github

after you got them, make a folder named reciever in [your local disk]\Users\yourusername\AppData\Roaming\devcoin
paste the recievers in there & try again

mine has been synced fully since yesterday and it keeps syncing itself


So I did this and the wallet very quickly made 8 connections with the devcoin network. So far (after about 5 minutes) it is still stuck on block 0, though. I'll let it run for an hour or two and post if it starts downloading blocks. If it doesn't download blocks, do you have any other suggestions? Thanks!
