Jumbucks New Wallet Version 1.8 - Maintenance update with directory name changes

Hi all,

A new wallet version 1.8 has been released for Jumbucks. This is a relatively minor update but does require some interaction from the user for upgrading as the data directory has been renamed. For existing users, please pay attention to the Upgrade steps below. New users may install the wallet as is.

For Windows users this update also includes standalone executable wallets for 32-bit and 64-bit systems.

Other improvements include new RPC commands and faster start up times.

Upgrade steps:

The data directory and configuration file has been renamed. This change was necessary to fully deprecate the old CoinmarketsCoin name to switch over to Jumbucks.

  • Backup your wallet.dat file
  • Shut down the current version 1.7 wallet
  • Rename the data directory the the new name described below. Rename configuration file (if you manually created one) from coinmarketscoin.conf to jumbucks.conf
  • Install the new version
  • Start up the new version 1.8 wallet and verify everything works
  • Windows users MAY need to follow the step of deleting everything in their data directory except for their wallet.dat file since the wallet is in a new executable format. This would require a full resync of the blockchain and steps to sync from a bootstrap.dat file are included below.

OLD data directory

Code:
Windows < Vista: C:\Documents and Settings\Username\Application Data\CoinmarketsCoin
Windows >= Vista: C:\Users\Username\AppData\Roaming\CoinmarketsCoin
Mac: ~/Library/Application Support/CoinmarketsCoin
Unix: ~/.coinmarketscoin

NEW data directory

Code:
Windows < Vista: C:\Documents and Settings\Username\Application Data\Jumbucks
Windows >= Vista: C:\Users\Username\AppData\Roaming\Jumbucks
Mac: ~/Library/Application Support/Jumbucks
Unix: ~/.jumbucks

Download links:

Github: https://github.com/jyap808/jumbucks/releases/tag/v1.8

Changes:

  • Updated some QT wallet images such as the splash screen
  • Added getwalletinfo RPC call
  • RPC command liststealthaddresses - Multiple address fix
  • RPC command liststealthaddresses - Results reformatted to be consistent with rest of RPC calls
  • RPC command sendtoaddress - Call sendtostealthaddress if passed a stealth address
  • RPC command sendtoaddress & sendtostealthaddress - Reordered params moving narration to end
  • OpenSSL DER fix to allow for latest versions of OpenSSL
  • Decrease the default number of blocks to check at startup to 500
  • Modify DNS seeds to use getjumbucks.com domain and deprecate old coinmarketscoin.com domain
  • Remove redundant stake modifier checkpoints checks
  • Reduce nStakeCombineThreshold to 500 for smoother network staking

Bootstrap.dat file:

The Bootstrap.dat allows a new Jumbucks client (not synced) to rapidly import the initial blocks from a local file instead of slowly downloading blocks from random peers. This significantly reduces the time it takes to get a client synced with the current blockchain (minutes instead of hours). Simply having bootstrap.dat in Jumbucks' expected data directory will make your initial block sync much faster.

The current Bootstrap file is at block 414,811 (May 25, 2015).

Regardless of your operating system use the following steps to make use of the bootstrap.dat file:

  • Download bootstrap.dat.xz
  • Verify the integrity of bootstrap.dat.xz with the checksums.
  • Decompress to obtain bootstrap.dat.
  • Put it into the Jumbucks datadir. This is the same folder that contains wallet.dat and the blocks folder.
  • Delete bootstrap.dat.old if you want to recover some storage space.

Signed version tag:

This version has been tagged and signed as v1.8 in Git.  Verify it using my GPG public key on https://keybase.io/jyap.

Code:
$ git tag -v v1.8
object 2a187cd3379512b1b1c3228ad80bab4a9ce7d638
type commit
tag v1.8
tagger Julian Yap <> 1432435937 -1000

Signed 1.8 tag
gpg: Signature made Sat May 23 16:52:17 2015 HST using RSA key ID 7F661F0A
gpg: Good signature from "Julian Yap <>"

Bitcointalk new coin announcements Twitter bot for the Jumbucks and crypto community. Some logic is involved to try and filter out spam.. so may not Tweet all launches.


I am a bit disgusted how much nonsense coins are launched everyday. I missed most of them and that was probably a good thing, but of course I cant unfollow anymore.

Nice work jyap. ty.

Hi @ShapeShift_io. Please consider adding #Jumbucks $JBS. Stable Proof of Stake cryptocurrency around for almost 8 months. Thanks!

Well we've been discussing via email as well.


presume focus is on volume, approaching that way without out it makes no sense

try more community building first with way out of ordinary methods (thinking)

you can't get something without giving something sometimes i guess - or am i just stupid

It's hard to say what their criteria is (the didn't say specifics) considering a particular coin on their service has less than $10 worth of volume.

But Shapeshift did mention that Jumbucks is up for consideration.

- Julian


imo they're playing a little too safe and cautious (considering the coins they've strictly added) - works both ways I guess

someone might just step in and offer a wider service soon if they don't change strategy or maybe not

just random ramblings

Syncing the wallet from 0 is taking a long time. Several days in I'm still barely half way there. If there's a way to speed it up please advise. Thanks

Hi. Sync shouldn't take that long since there are lots of nodes.

You can try the bootstrap.dat method. That should be much faster.

Details here:

Agreed.  I like that this is moving on slowly and steadily and without hype.  Whilst in the past I used to invest in every shiny new coin (the glory days of early 2014!) now I try to invest in people that I trust and believe in.  As long as Julian is involved with this it will continue to have my support.

Hell yes....just quiet the same with me when seeing a new coin Cheesy....but currently there are too may of them, really like a bunch of mushrooms during raining, become too hot too handle at the market 'till got loss for the bucks, even though sometimes that's the art of trading right? Smiley
Tired of that, it's about time to keep our money at the right one and I'm really sure that jbs could be the one.

A little bit scary now when jbs at the first page of bittrex, hope that those whales will not make a play for a dumb instead of a dump. But it's ok, bought jbs at half price of the present time and i will keep it, not much but valuable, a truly valuable coin to be kept.

Will make a donation to Julian as the dev if he doesn't mind with my tiny amount Smiley

Keep rockin' guys  Wink

Jumbucks Development Update

I wanted to give a quick update.  Jumbucks is over 7 months old now (launched September 2nd, 2014) but I've always considered it very early for cryptocurrencies in general.  That's taking the long term view to digital currency adoption.

We've seen a lot of coins come and go so when I started my own coin I really wanted to make something which would "stand the test of time".  Longevity is still a goal and a constant challenge but that is something a coin developer should accept and rise to.  Their goal should always be to provide more value to the coin and in my view, in the most ethical way possible.

A lot of the possible security flaws with Proof of Stake come with a poor Proof of Stake network where not many coins are staking and bad actors can exploit the network.  Thankfully Jumbucks isn't in this position and has performed very well in terms of stake percentage (typically over 50%).  This is something I planned for when I implemented 8% Proof of Stake interest.  My thinking was that this was a good balance between early adopter staking, long term investing, coin distribution, inflation, etc…

One thing I want to do is move towards Proof of Stake 2.0 as implemented in Blackcoin.  This addresses some more possible security vulnerabilities.  I'll be testing this out with certain changes so that staking remains smooth and stable.  We have implemented quite a few code changes over time such as RPC additions and fixes, the MAX_BLOCK_STAKE_REWARD setting, Gitian build scripts to the Jumbucks code base.

In the future, should cryptocurrencies take off we'll want to have dedicated devices to perform our staking duties.  We don't believe in centralized cloud staking as this is insecure and gives too much power to a single entity.  We're working on something to address this and make Proof of Stake more safe, secure and automated.  We'll also be discussing this with some other coin communities as well so they can benefit from our work.

The MAX_BLOCK_STAKE_REWARD setting in Jumbucks also discourages centralized staking by capping rewards and encouraging a well distributed Proof of Stake network.  The MAX_BLOCK_STAKE_REWARD setting also prevents possible Proof of Stake coin inflation attacks which can be caused by single entities such as exchanges who are in control of a large amount of idle coins and can mint a large amount of coins.  There has been examples of this happening and this is a real threat.  I've started a short whitepaper as well which outlines the MAX_BLOCK_STAKE_REWARD setting.

Another thing we'll do is move our primary real-time communications system from IRC to Slack.  Slack has quite a few benefits such as more modern integrations and should be inviting for newcomers.  We actually have Jumbucks Slack set up already but we want to test out a few things (such as a public gateway, interactive elements, bots) before opening it up to the public.  The free version of Slack is limited to 5 integrations so we want to make sure we use those to the fullest.

I Tweeted at one point early on that I wasn't going to comment about price for JBS. That still remains true and I've refrained from retweeting or mentioning anything price related.  Ultimately price should reflect value so we want JBS to be viewed as a long term coin with dedicated developers.  Basically JBS is a coin that I would personally invest in, had someone else created it.

JBS was always viewed as my experimental coin and the work is also intended to add value be it through more services, better infrastructure and so forth.  I spend a lot of time checking out various blockchain related projects and discussing them with the other Jumbucks developer @iquidus.  One thing we really want to do is something along the lines of a distributed hash table for data storage, tied to the Jumbucks blockchain.

Thank you for your support and for following along.

- Julian


Jumbucks is a Fair Launch cryptocurrency which launched without an IPO and with zero premine.  Jumbucks currently runs as 100% Proof of Stake, and is currently traded on Bittrex, Cryptsy and will be available at launch on the upcoming AltMarket.com.  Find out more information at GetJumbucks.com.

I see on getjumbucks.com that this coin is a fork of ShadowCash. Then what does that mean the proof of developper of jumbucks if it's only a fork?

The codebase was originally forked from SDC yes, just as SDC was originally forked from Blackcoin. There have been many commits since the initial fork, I'm not quite sure what you are trying to get at here? (as everything is a fork of BTC). Both myself and jyap have attached our real names to this project, which can not be said about most coin devs.

We are working on a number of things, ranging from improvements to various parts of the coin codebase to jbs service infrastructure, and of course the Pi project which is getting most of my focus currently (see the @getjumbucks twitter for sneak peeks at the next phase of the Pi project).

Please keep in mind we don't get paid and it was a 100% fair launch, so our time/attention gets shared with other work (bills dont pay themselves). We spend a decent amount of time helping out other developers/projects in the crypto community etc and have various real life commitments (we are people too ;P).

The jbs team is in this for the long run, we have big plans for the future, and the right skillsets to make them happen.

We don't update this thread very often but jumbucks is being very actively developed. To stay up to date follow @getjumbucks on twitter, or visit us in #jumbucks on freenode. We are also in the process of setting up a jbs slack community.

Guys, if you want updates, check the original coin ShadowCash:
https://bitcointalksearch.org/topic/m.11002986

There are some updates in our Github.

We've been working on stuff. I've posted some details on our Twitter account @getjumbucks and IRC is a good place to chat as well (#jumbucks on Freenode).

But thanks for stopping by.
