I wouldn't bother with my torrent link. I've had mixed results with a failed tracker. I think I generated the link wrong.
For such cases, there is no way to modify tagged data already uploaded. What we could do, without adding new transaction types, is use referenced transactions to add a comment to existing data, by submitting a plain text message with no recipient and referring to the data upload transaction, and then use the recently added getReferencingTransactions API to find and display such messages as comments for the data they refer to. This would be just an UI change, worth doing only if there is demand.

Downloading the full blockchain from scratch takes exactly 2 hours for me. The limiting factor is not the network, but disk and possibly CPU.

So, if I'm running a 32-bit machine, am I out of luck with this new release?
You would need to install a 32-bit JRE manually, and then use the zip package instead of the exe installer.

Of course there is a security issue, this is why I don't encourage such downloading of the blockchain from a torrent or website. If the normal way of downloading it with the client takes 2 hours on modern hardware, this is fast enough. I have heard stories of users taking days to download the full blockchain, those must be on slow machines, I have no other explanation. For such users doing a rescan will also take very long, but without a rescan (and also comparing the last block with the network) they must trust the provider of that torrent or zip archive.

On my Raspberry Pi1 node the blockchain took days to download.

True, the same happened to me.
It's funny to see how a node can be run (quite smoohtly) on a low-end hardware, like an old Raspberry Pi or a cheap (or even free) VPS but, on the other side, it can even take a couple of days to fully download the blockchain (<2GB) and be ready for action.

Just for the record, I upgraded from 1.6.2. It worked in the end but took a while.

I run my node in a docker container running on a rather powerful NAS (Synology 1815+).
I always backup my db to avoid having to re-download it.
The db upgrade from 1.6.2 to 1.7.4 was rather quick (couple of minutes I would say) but the rescan boy.... from 14:12 to 06:21 next day :)

But all worked fine. Today the compressed db is about 500MB, this is not worth spending the time to download it. I suggest you make your own copy. Even if this is a month old, it is still much quicker. It would be a nice option in the client to be able to dump a copy of the db periodically in a folder (for the lazy :))

Is the left bar completely hidden or just covered partially by center area ? Can you try to click one of the transaction links on the dashboard to see if this fixes the problem ? Do you see an error message in the JavaScript console ?
If this still occurs please post a screen shot.

After block 621000 these deleted shares will disappear. You'll be able to track these transactions using the account ledger or using the delete history page in the asset exchange menu.

thx for the new release. i have one suggestion for the client but didnt found a suitable sub forum here for it:
in the marketplace (and anywhere else) we only see NXT amounts. would be nice to also show EUR or USD amount. especially in the marketplace. its easy to poll the price API from www.cryptocoincharts.info for example. one quick thing would be to show the other currencies amounts as tooltip when hovering over NXT amounts.

I don't understand this one... It's not the same as the Nxt Mac Wallet?

Is there any way for the ledger to show more than (for me) 106 items?

When I go to my ledger it stops at 106 entries (about a month ago)

I already put nxt.ledgerTrimKeep=0 in my config

# Specify the number of blocks to keep when trimming the account ledger table.  A value
# of zero will cause all blocks to be kept.
nxt.ledgerTrimKeep=3000

Hi J-L!

2 Questions about the current 1.7.4 release:

1) I see data cloud: can you compare it with storj, maidsafe and opal drive? Do we need http://www.nxttechnologytree.com/nxt-technology/nxt-distributed-storage in order to be a distributed Google Drive?

2) Account Control, how does it work?
With Bitcoin I had to download Armory wallet, create at least 3 new accounts and magically I had a multisig address starting with the number 3. How do I achieve it in NXT?

Thanks!!

I think you need to rescan the blockchain. Which I believe you can do from http://localhost:7876/test?requestTag=DEBUG and explore the scan API. Setting height to 0 will rescan from the genesis block. The database will get a bit bigger.

(When I needed this, I set nxt.forceScan=true in the nxt.properties instead, but the API is probably better.)

2) Account Control, how does it work?
From the home page, click on the Account Balance More Info >, then the Account Control tab. This will let you set up mandatory approval for the account, which essentially means all its out-going transactions must be phased transactions, which means they must be approved according to the rules you set up here.

For example, if you wanted three signatures needed, then add the other two accounts to the whitelist under the second tab, and set the Number of Accounts to 2. If you wanted two out of three, then set Number of Accounts to 1. The current accounts signature will always be needed. If that's a problem, you can add a fourth account, set Number of Accounts to 2, and share the pass phrase for the current account with the other three people.

You really need to understand how phased transactions work first, before using account control.

Once account control has been setup can it be removed at a later time to restore an account back to basic?
Yes. The transaction that does this is subject to the existing account control, of course.

(I don't think there's any way to set account control to expire, although that might be useful as a safety net.)
