Security update: Nu 2.0.3 and B&C Exchange 3.0.2

[desrever]

Maybe also include bcexchanged ?

I would appreciate if someone else could maintain an unofficial bcexchanged.

Strongly suggest to add Raspberry binary on homepage.

We can’t because it’s untested software.

please compiled with BerkeleyDB 4.8

I actually never got the time to figure it. I remember we were discussing this some time ago … Apparently I am compiling with 5.1

$ cat /usr/lib/sasl2/berkeley_db.txt
5.1

I remember that uninstalling bdb wasn’t streightforward for someone so I was waiting for someone to figure out how to do the downgrade properly before corrupting that machine.

Is there a warning, because using 5.1 renders wallets incompatible with the official clients?

docs.nubits.com has an updated Raspberry Pi section explaining how to get 4.8 on a RaPi2.

I see. We should harmonise the tutorial a bit more. Now we are basically first telling “install libdb+±dev” , and then we say “don’t” . If you can, please edit the tutorial with just one version of dependencies instructions.

[masterOfDisaster]

Both 4.8 and 5.1 are options and users might choose the one that suits them best.
I wouldn’t dare say that I can decide that for anybody without knowing the requirements.

With 4.8 the wallets stay compatible with the official releases.
With 5.1 users don’t need to worry about compiling their own libdb on RaPi2 (and using it for compiling nud or bcexchanged), because 5.1 is in the official repos.

[desrever]

any particular reason why official nud uses 4.8 ( cc @sigmike ) ?

any particular reason why official nud uses 4.8

Mostly because that’s what Bitcoin and Peercoin use and we didn’t change that. The fact the wallet files work on all versions is also interesting.

@mhps @masterOfDisaster
Can you edit a manual of how to mint BKS on Raspberry for those only reading B&C hompages? Then we can put in on B&C website.

[mhps]

how to mint BKS on Raspberry

It’s almost exactly like https://docs.nubits.com/nu-raspberry-minting/ – just change nu and nubit to bcexchange and nud to bcexchanged

BTW, how about put source code (less than 30MB)on blockchain, so that if our website/bitbucket.org hang for some reason(eg attacked) , users still can download source.

blockchain storage is similar with bittorrent, isn’t it?

[Sabreiib]

When B&C in operation, some people may only browse B&C website, inconvenient to find answer in another pages.

I like the idea, but not 30 MB per version. The Git repository… incrementally? How would people download it, and do you suggest custom blocks for data? How much data can we store in each block right now?

Publishing version with hash in blockchain and letting people find a download elsewhere might be useful.

[Sabreiib]

Since miners share Nu/BKS blockchain data(up to 1GB even 40GB) in decentralized mechanism, we can share source code in same way. It is a simple bittorrent application.

this should be pinned.

Tks @CoinGame .

[Sentinelrv]

Finally upgraded. I’ve been away on vacation and only just got back now.

[nubition]

I am running the 2.0.3 Beta version was there changes after that or is that fine

[Ben]

You are on the correct version. 2.0.3 is the most recent.

rat4, the main developer of Blackcoin, claims that the fix is not complete:

The fix is not complete. A signature contains three encoded lengths, but the patch covers only one of them.
