Another update on the state of DPoW integrations: (Repost from Komodo Discord)

1.) Notary Node  addresses & wallet building is underway. You can see the beginnings of the address work  here: (https://github.com/blur-network/dpow-blur/commit/1d4397c4da4b70eb3a66a911c4e3c78b1c138b53).

Understanding how this will work with NN pubkeys, requires a little background on XMR addresses.  In monero's ecosystem, each wallet address consists of two separate keypairs (4 keys in total, 2 public, 2 private). These consist of a viewkey pair, and a spendkey pair.  If keys are truly independent (they are deterministic in XMR, but will not be for notary nodes), the private viewkey can be used by third parties to transparently view the transactions. This is possible without the viewer having any way to actually compromise the funds of the wallet in question.

 jl777 and I spoke about about ways to employ the existing BTC pubkeys that notary nodes currently use, and avoid requiring submission of private keys of any kind... What we settled on was repurposing the current btc pubkeys as private viewkeys for  notary nodes on BLUR.  For the other keypair (spendkey), a new crypto library, built on Ed25519 and GIMLI permutations, called libhydrogen will be used to generate a high entropy secret spendkey.

This means that NN operators will only have  to provide their pubkey on startup of blur-notary-server-rpc, and a unique wallet address will then be generated.

2.) An extra parameter for dpowconfs has been added to the wallet, and notary wallets: (https://github.com/blur-network/dpow-blur/commit/38d8a482302a57479d1b4e174d6b74145171e6d7).

3.) All of the types, classes, etc necessary from bitcoin have been consolidated into the directory external/bitcoin (which compiles as a static library).

 I've also added a couple helper functions in src/common/hex_str.cpp for conversions between the two codebases. Converting from BTC style uint256 to cryptonote's crypto::hash is pretty simple this way, and we don't have to do any crazy type-punning.

4.) Unique ntz_txn tags & fields in the extra have been added, and have preliminarily been given a buffer of 4kB or so. (https://github.com/blur-network/dpow-blur/commit/f6deef44d41847c7e8125e40c606379cc325af27 & https://github.com/blur-network/dpow-blur/commit/6ade53a6548c983dae100ef24159548ba188c999)

5.) komodo-related DPoW functions have been built with main lines into cryptonote::core via the komodo_core class.  This class has a constructor that initializes m_core and m_p2p as references to cryptonote::core and node_server.  These are the two handlers that dictate consensus, effectively.

 - Here, core will allow us to load in state files, checkpoints, etc.  There are already placeholder functions (without bodies) for this.  You'll find all of komodo_core located in src/komodo/komodo_validation.cpp & .h

In BLUR consensus decisions begin in core and p2p as far as network communication goes.  These decisions are then finalized in src/cryptonote_core/blockchain.cpp where they are added to the blockchain, or rejected based on verification & hard fork rules

[blurnetwork]

Implementation of addresses with non-deterministic view/spend key pairs is complete.  See the README.md at https://github.com/blur-network/dpow-blur for details on how to use the notary-server-rpc to generate an address.  These addresses are LIVE and will be able to spend/receive funds.  Only do so if you are an experienced user.

[blurnetwork]

Libbtc has been added to the DPoW-Blur repository for Bitcoin transaction parsing.

Timeline has shifted back slightly on the DPoW integrations, as some may have noticed. Patching the vulnerability from the XMR wallet bug necessitated the immediate attention. DPoW code should be done in roughly two weeks, as a result.

Hope you will be doing good and this is going to be a success story I've heard something about this project from outside of this forum.

[cuttie018]

Hey, guys, good idea! Do you have a crypto-development background? Checked repository. It's straight-forward. How are people in your team?

[blurnetwork]

UPDATE: For those interested in progress on the DPoW integrations, the README in the DPoW-Blur repository has been updated!

You can access the repository here: https://github.com/blur-network/dpow-blur

Please note that the RPC methods included there are unfinished currently, but have partial functionality.

The ntz_transfer command issued to blur-notary-server-rpc will currently generate a single Tx with 64 destinations.  Subsequently, this transaction (signed by a single notary node) is relayed to the network as a request for more signatures.

Once the count for signatures reaches 13, the transaction will be relayed. You can simulate this behavior by changing sig_count to 13 in either RPC call:

1.)  request_ntz_sig sent to the daemon with a signed tx_blob

or

2.) ntz_transfer with sig_count = 13

Further functionality of authenticated tx creation, and automatic signing will be implemented in the next few days.

Would be nice to see the exchange coin. Will this be pump-and-dump coin, or a serious project, guys?

Have you ever had similar project here at BCT? Seems like I've alreday seen such projetc here. Maybe i am mistaken though...

Recent jump in hashrate / difficulty... roughly 3x from a few weeks ago. Any news on this?

I look forward to the bounty program. I think this will statr as logical as I have very little information about the project.

Sorry, I have not been checking bitcointalk often, as the development work on DPoW has been keeping me busy.  Things are at a very discernible point of functioning, from a wallet, daemon, and protocol-level standpoint.  I'll post an update here in a bit, on the development progress.  It's been a while since I updated everyone.  But have exciting things to share from code

Still a bit more work to go, but things are quickly getting closer to being done.

Good afternoon.
I have an old daemon and wallet version blur-v0.1.7-win-x86_64.
I used to update your binary file without any problems and transfer my wallet to it - there weren’t any problems.


I downloaded your new version - blur-v0.1.9.8.1-win-x86_64.
But my password from my old wallet does not work now.
What is the problem? What should I do and how to get my coins?
Thank you in advance.


I went into the old wallet and got my seed.
Then he tried to restore the wallet through his seed, but received an Error: Multisig seed failed verification error.
What am I doing wrong? How do I get my coins?

UPDATE: DPoW development on Blur is nearing completion.

You will find, below, an update on the progress so far:

1.) Code for keeping track of notary node signatures (sig_count), and an index for keeping track of which nodes have signed the pending_tx (signers_index), is complete and functional.

2.) The code to start creation of ntz txns is mostly complete, and is functional. Some refining still needed. To create a ntz tx, notary wallets will call the RPC method create_ntz_transfer

- The first two times that this method is called (performed automatically on notary wallet launch), the wallet paces the resulting pending_txinfo into a container. Since this RPC call takes between 5-15 seconds to complete, the cache will be used to speed up response time to the NOTIFY_REQUEST_NTZ_SIG protocol command, which is relayed automatically each time signatures are added, or upon creation of a new pending_tx

- Creation of  a notarization request is authenticated, and checked against the hardcoded pubkeys located in src/komodo/komodo_notaries.h.

3.)  Each notary node is given a signers_indexvalue, corresponding to their specific node. This value is appended to the index (which is an array, holding 13 values). Before signatures are appended, this field holds a default value of “-1” as a placeholder.  A partially signed transaction with a single signature will look like:

Code:

51 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1

4.) An RPC method append_ntz_sig has been added to perform the act of appending further signatures/outputs to a pending_tx, relayed by NOTIFY_REQUEST_NTZ_SIG

Currently, relay messages via protocol are fully working for requests.

You can find more details on these methods, etc.  As well as how the mempool treats pending ntz txns differently from regular txs, in the README.md located here: https://github.com/blur-network/dpow-blur/blob/dpow/README.md

If you wish to help test these additions, and the new difficulty algorithm (Monero's DAA with 1 minute block times) which will both be added at the next hardfork (v11)...  a version 11 testnet is currently live and running with these changes.  You will need to compile the dpow-blur source to run a node on the testnet.

You must be mistaken. This is the first project I’ve created. Planning on it being the only one as well.


It’s a part of why we are choosing to confine things to a single enclosed ecosystem. I feel that a lot of what goes on with CryptoNote clones is bad for crypto in general. We don’t need more copy coins. I think that if one is going to do so, there should be an expectation of it being made known that the developer has multiple projects... and I think that they should be confined to the same ecosystem, in that event. But this is just my personal ethical compass

No more trading volume in altilly dev? What is happening? But there is a long list of buy and sell orders though. I checked this to see if I can cpu mine this coin because the price is not bad as compared to other cpu mineable coin. However, I want to check the current difficulty but your explorer is not up :
