Technical Support / Network Security Question
« on: October 22, 2015, 06:00:38 am »
We've recently discussed some witness automated backup solutions that could possibly end up signing 2 different forks for a single witness.
In such case (assuming more than one witness use the script) we could have multiple forks with >50% participation which  is obviously extremely undesired.
We had a relatively easy way to check if someone signs in two forks in BTS 1.0 (and we had a massive amount of double signers).

My question to @Bytemaster is how do we guarantee this doesn't happen.

When will we have public testnet for Bitshares 2.0 ?

Stakeholder Proposals / bitOil Suggestion
« on: February 05, 2015, 03:32:15 pm »
As there is some demand for bitOil as discussed here:

I'd like to propose the following:
We could create multiple market issued assets like ( Crude Oil Mar 15 (CLH15.NYM) ) and publish feeds.
But the client should be modified so that:
1 All feeds are invalid 1 day before target date.
2 All positions are closed 1 day before target date.

[17:16:10] Emil Velichkov: there are multiple delegates running 2 instances
[17:16:10] Emil Velichkov: dev0.nikolai
[17:16:10] Emil Velichkov: delegate.rgcrypto
[17:16:10] Emil Velichkov: dev-trial.misc.nikolai
[17:16:10] Emil Velichkov: Why ?

General Discussion / Volume And Peg Question
« on: February 05, 2015, 08:49:17 am »
Imagine the following situation:
We have a real-world market for the asset A. Total world trade volume of asset A is $1 mil.
Bitshares implements bitAsset for A (bitA) and it starts trading on the blockchain.
Lets say there are shorts for total of $100k .

The question is: When it would be profitable for an entity (mr. X) to manipulate real world price of A (buying selling on the real exchange) so that for any dollar spent on the real world exchange X gets at least $1 worth of value on the Bitshares blockchain.

DevShares / New DVS Delegate: emski
« on: January 20, 2015, 09:30:22 pm »
I've registered "emski" as delegate in DVS network.
I'd be happy if someone votes for me so I can prepare feed script for the updates and make some testing.


Stakeholder Proposals / What is the Reason For 0.4.25 Forks ?
« on: December 12, 2014, 11:52:22 am »
We have seen 0.4.24 and 0.4.25 forked before the predefined block.
Am I correct that this could be identified before release with (simple) testing ?
What procedures were followed prior 0.4.25 release ?

Main questions:
Why we have forking 0.4.24 and 0.4.25 before block 1249400 ?
Wasn't this relatively easy to prevent ?

Stakeholder Proposals / Trapped Funds in EUR
« on: November 28, 2014, 08:51:00 am »
Currently there are not enough EUR price feeds.
This market had more than 51 at one point in time so there are about 2k EUR in circulation.
These funds are trapped until 51 delegate feeds are provided.

Can I ask why the feeds are less than 51?

Stakeholder Proposals / Technical Delegates Real Time Chat
« on: November 26, 2014, 06:57:52 am »
I think it would be wise if we have real-time chat with people maintaining delegates and/or tools for delegates.
This will help for faster issue identification and resolution.
I suggest we crate a skype group for anyone interested.
PM me your skype IDs and I'll create such group and add you into it.

PS: If you believe another messenger should be used -> state it here.

EDIT1: Skype group: http://skype/?chat&blob=s7FK3ZkYII8DujtoAK6x7aTaeUTLgBMEWpeFAD0aRgPq6LKo2cJcynSH_xoV9V9xRd2pY_xjdv_rh88

Stakeholder Proposals / Warning For Delegates Producing Price Feeds
« on: November 13, 2014, 09:09:04 pm »
BTER changed the asset name for Bitshares. It is now BTS (old BTSX was removed).
I've updated my version of the script: .
I suggest you check if the change concerns you.

EDIT: It is a bit "patchy" but I'll try to make it better when I have enough time

General Discussion / [Proposal] DAC System Account
« on: November 12, 2014, 08:28:33 am »
I suggest a special DAC System Account to be defined.
All registration fees (and possibly trx feex) should go there instead of being burned.
The funds from this account should be used to pay delegates. Dilution should occur only when this account goes to zero.


General Discussion / Warning: Accounts similar to current delegates
« on: November 04, 2014, 11:42:29 am »
I've noticed someone just registered accounts on the blockchain that are very similar to current delegates.

For example:
Nov 4, 2014 10:18:50 AM   30426   delepuppy
Nov 4, 2014 10:17:00 AM   30425   emskibitdelegate
Nov 4, 2014 10:15:30 AM   30424   dacbts500
Nov 4, 2014 10:14:00 AM   30423   daccoolspeed
Nov 4, 2014 10:11:50 AM   30422   btsapp
Nov 4, 2014 10:02:00 AM   30421   dogep2p
Nov 4, 2014 10:01:30 AM   30420   ltcp2p
Nov 4, 2014 10:01:10 AM   30419   dacp2p

If you are going to vote, please double-check the names.
I've shown how robohashes are inefficient for protection (see the first reply).
Until a better system for user protection is implemented (see everyone should be extra careful when sending money or voting.

General Discussion / Who is barwizi ?
« on: October 24, 2014, 07:00:30 am »
I've stumbled upon
It reads Helpdesk Staff. So I was wondering who he is.
