I don't understand what you're trying to say about passphrases.

Really? That's not a very good mnemonic sentence! 

Just a friendly reminder to all about user-created passphrases: our minds are all connected, you are not that unique, and when there are 100 million Shadow users I can guarantee you I'll be able to enter the first 12 words of Jabberwocky, or Stairway To Heaven, or verses from the Bible and get my monkey paws on somebody's coins. Can't do anything like that.

Wonderful update, looking forward to firing it up, maybe tonight.

Great, thanks dasource. This is really key info that was missing, glad to have it!

When you first load the new HD wallet it will create a new HD account for you and set it as default ... I.e. any new addresses generated will be from the default HD account (unique to you). However as this is pre-generated and not user friendly to remember I suggest you proceed to create a new account using a mnemonic sentence.

My suggestion for existing users is ...

** ALWAYS BACKUP WALLET.DAT FIRST **

STEP1

1. Save your wallet.dat and rename it.
2. Load the new Shadow Latest client
3. Create a new HD Wallet (Options --> Key Management --> New Key) - give it a "name".
4. Goto Key Management --> Advanced Management and make sure that the new "name" account is showing as "default".
5. The wallet will have pre-generated a Default normal and stealth address
6. Send some funds to test (from your old wallet)

So now I would suggest you try a restore of this account to test it!

STEP2
1. Save your wallet.dat and rename it.
2. Load the Shadow Latest Client
3. Goto (Options --> Key Management --> Restore) - complete steps
4. Goto Help --> Debug --> Console and type "scanforalltxns 590000"
5. You should see your test transaction show up.

If all works, you know you have the correct mnemonic and can then go back to your old wallet and send all your funds to the new wallet.
Your new HD wallet is setup and the mnemonic sentence + optional pass-code is all you need to access all new addresses.

Both of those things happened last year, troll.

Just a friendly reminder:

Do not download wallet updates from quoted posts. Seek the original post and make sure the DL url is a shadow.cash link. 

Amazing update!

Regarding the upgrade to this HD wallet, what's the procedure?
— Should we first create a new account via Key Management? Or just create a new address as usual and then somehow pair it with the account?

Update: Thursday, October 1, 2015

Hello everybody,

It’s time for another development update to bring you up to speed with recent changes in the Shadow project.

The last weeks our main focus has been on the successful implementation of the HD Wallet into the ShadowCore platform, fixing GUI issues, bug smashing, testing, testing and more testing. While Tecnovert, St3bas and myself have been working on getting new Shadow components ready for our upcoming releases, a team was set up and is currently updating the documentation and writing new tutorials to help users navigate through the various features that are available for Shadow. We have launched a new, up to date, documentation website (doc.shadowproject.io) and will be adding text and video based tutorials as we move along. Details about the documentation will be revealed on our official development blog (blog.shadowproject.io).

For now, let’s look at some of the updates in more detail.

Hierarchical Deterministic (HD) wallet
We have successfully implemented a BIP32 framework and keys (HD Wallet) on which we will be building many interesting features in the future. For now, we have implemented a hierarchical deterministic wallet; that allows you to recover all the keys in a wallet using only the master key.

The latest version of ShadowCore is released and contains lots of code improvements and bug fixes. The biggest change is the implementation of a complete HD Wallet and a totally new user experience for management of your wallet keys. This was a fairly extensive update from our core developers. You can view the full details of the 156 changed files with 17,818 additions and 2,451 deletions. There’s a summary of the changes in the release notes here.

HD wallets really opened up a field of possibilities for Shadow because they are useful for multiple aspects of the project. For example: the implementation was a big step towards the release of our decentralized marketplace because we will be using BIP32 keys for the market categories. They allow us to have tree level categories in messages, so people can subscribe and publish to certain categories.

This HD Wallet consists of the following implementations:
BIP-0032; hierarchical deterministic wallet
BIP-0039; mnemonic sentence for the generation of deterministic wallets
BIP-0044; multi-account hierarchy for deterministic wallets

Technical Aspects:
BIP32 - https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki
BIP39 - https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki
BIP44 - https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki

Below you will find some of the new features and advantages that these implementations bring to the Shadow platform:

- You now only need to create a backup on initial creation.
- Easily backup and restore your wallet without needing any other information (wallet backup and restore consists of simple list of 12 to 24 common words).
- Conveniently create a single backup of the seed in a human readable format that will last the life of the wallet, without the worry of this backup becoming stale.
- New receive and change addresses are used for each transaction.
- Easily and securely accessed your wallet from multiple devices (Desktop, Mobile).
- Use the same 12-24 mnemonic sentence as your Bitcoin HD wallet to create a Shadow wallet.
- You no longer need to create a physical backup that can be traced or linked to your identity (just make sure you remember the 12-24 mnemonic series of words).
- Use a single seed that generates all private keys (never lose any coins because you forgot to do a back up).

All of the above comes together into a very simple and elegant solution which brings you the first native hierarchical deterministic wallet on the Satoshi code base!

Hard Fork for Ring Signature update
We are ready to implement a new ring signature scheme on mainnet that is based on the efficiency improvement work of Adam Back and Andy Toshi. It offers a stunning >42% improvement over our current ring signature scheme. To add these changes we have implemented a hardfork for the 19th of October 00:00 GMT. Please make sure you have updated your client to the latest version before then.

To demonstrate the difference between the old and new ring signature scheme, see below for the before and after size of the data stored in the blockchain for a transaction with 16 ring signatures.

Before hard fork: ≈1.5KB
After hard fork: ≈1.11KB

To run the tests yourself, make sure you have all the dependencies needed to build the deamon, then cd shadow/src && make -f makefile.unix test, then ./testshadow -t ringsigtests -l all > ringsig_tests.txt.

ShadowCore v1.3.3.3 ***LIVENET***
Before downloading any of the files below, please make sure to backup your wallets first! The Shadow team uses Gitian as its software distribution method. Gitian uses a deterministic build process to allow multiple builders to create identical binaries. This allows multiple parties to sign the resulting binaries, guaranteeing that the binaries and tool chain were not tampered with and that the same source was used. It removes the build and distribution process as a single point of failure. We strongly advice you only download from official websites and if in doubt always double check.

Please note: Windows 10 pre-installed settings are privacy-intrusive by default, we highly recommend changing these settings. Go to: https://github.com/10se1ucgo/DisableWinTracking or http://windows.microsoft.com/en-us/windows/preview-privacy-statement for more information.

ShadowGo
The next release of ShadowGo is currently undergoing final testing. Once we have ironed out the last bugs we will move it to beta and begin public testing! This new version of ShadowGo uses the new SHA256 algorithm creating quite a number of improvements in terms of security, processing power and energy consumption; overall the update has resulted in a huge 60%+ reduction in the memory footprint of the application. To give you an idea the previous application used to consume between 650-750MB whereas the new one is ~100MB.

To give you a heads up, some of the new features will include:

- Latest HTML5 Interface (new responsive design)
- Thin mode support (less memory consumption)
- ShadowChat support (encrypted messaging)
- ShadowSend v2 support (private transactions)

ShadowMarket
Now that we have successfully managed to implement a HD wallet into ShadowCore we will be moving on to the next stage of ShadowMarket’s development! Let’s take a look at what our team will be working on next:

- ShadowCore V1.3.3.3 hardfork (19th October 00:00 GMT)
- ShadowCore GUI v2 (November 2015)
- ShadowMarket v1 (November 2015)
- Decentralized Escrow (tba)
- Voting + Feedback and rating system (tba)
- ShadowChat v2 (tba)

Now that most of our core developers are focussed on ShadowMarket’s development we’re getting closer to to finishing the first version (Alpha) of Shadow’s decentralized p2p commerce platform. Please note that the ShadowMarket Alpha testing phase will be exclusive and testing will only be available to a select number of people. Starting with community members that have made a donation or contributed to the Shadow project in the past. Stay tuned, because we plan to start sending out private invites around November this year!

That covers our development updates for now. As always, we look forward to hearing about your experiences and kindly request you send us your feedback on IRC or SLACK. You can stay up to date with our progress by registering to ShadowTalk, subscribing to our development blog or following us on twitter.

Dev tallent, new and old comunity members are most welcome. Please, no trolls. We just dont have time or patience for your rubish.

OK, excellent. I haven't used the daemon yet so I've never seen this. Now why is it that if I were to try to convert some odd amount, it tells me "Outputs not available" sometimes and I have to choose something else? Are the outputs that can be used equal to the No. Exists minus the No. Spends or something?

SDC recovering nicely. Less then 10 BTC all the way up to 53k 

Meh, Deep Web article is from January.
Your coding skills must be exquisite, I'm sure. But decentralized marketplace isn't your ordinary blog where you just fiddle with CSS..

No real progress? Yeah, another smart guy who took those few mins to browse through Shadow's GitHub, heh?

"Don't feed the trolls", yeah I know. But still..

LOL almost a year from deep web article and still no Isidor review, no decentralized market, no real progress.

This is Liberty coin all over again.

Just leave bro. You really make yourself look incredibly stupid with like... every single post you put up. Go join skip on eth lols. Ya'll have had like a 60% decrease since you switched to that community... coincidence? I THINK NOT!

And didn't you say you were never going to post in here again? I think that makes you a liar.

Go back to your bridge, troll.

corrected to former community manager. sometimes it feels like im the only guy trying to be clear.


 

point stands tho - no news = orchestrated pump (probably). or maybe skip is back, LOL
no good whitepaper & docs= no dice

BTW I think BCT is excellent and has provided much. deleting posts is sad, especially for a group who hate censorship (theoretically)

I do not know other sign of superiority but kindness. You should learn it!

I dont know how a price increase (after a minor dump) discussion (and a discussion of Monero's price) is considered appropriate for this announcement thread. Also, child_harold, shut the fuck up.

LOL.
