General Discussion / BitShares Online Summit - 10 OCT 2019
« on: September 25, 2019, 09:00:46 pm »


BitShares Online Summit
10 OCT 2019

Description
Being the nature of a decentralized community, consensus building is an important component toward moving our BitShares project forward. Lacking effective communication, voices within our community cannot be heard, their ideas cannot be shared, and the overall project cannot be improved efficiently. This is your opportunity to participate in a meaningful discussion about the future of BitShares.

The BitShares Online Summit intends to leverage the collective knowledge within our diverse, decentralized BitShares community into a live unified online conversation. The summit will focus on topics related to Workers, Project Vision and Marketing of the BitShares project. The format will consist of presentations and Q&A (questions and answers), with open discussion facilitated by English-Chinese Live Interpretation Services to enhance real-time communication. All contributors and community members are welcome to join the discussions regarding issues, opportunities and solutions for growing a sustainable BitShares project.

The 2019 BitShares Online Summit is hosted by the BitShares Core Team, with event organization and coordination provided by Spark Blockchain Incubator.

What Makes This Summit Different
Sharing Insights
An online summit is an ideal venue for community members, committee members, workers, block producers, proxies and anyone contributing to BitShares growth to share their ideas. It is also an opportunity to question these ideas and seek to clarify information. We welcome all to participate using the conference tools provided.

Communication Among Participants
The conference will provide a direct channel for presenters to share their ideas and facilitate raising questions and soliciting feedback from the live audience. The audience will have 5-10 min to raise questions for each presenter following the 4-7 minute presentation.

Stakeholder Proposals / Core Team Worker Funding Status
« on: June 27, 2019, 01:37:51 pm »
I am pleased to announce that the Core Team Worker has fully funded its 2019 budget in bitCNY value due to the increased valuation of the BTS token. I am reaching out to proxies and community members to suspend their votes for this WP to allow other valuable initiatives to receive funding. The Core Team will continue its development efforts from the accumulated budget holdings in escrow with the BitShares Blockchain Foundation (should BTS valuation drop I may request lifting the vote suspension to fund the original intent).

Respectfully,
Ryan R. Fox
Development Coordinator

General Discussion / Core Team Recommendations for HTLC Parameters
« on: April 03, 2019, 02:05:23 pm »
TO: BitShares Committee
FROM: BitShares Core Team
REFERENCE: https://github.com/bitshares/bitshares-core/issues/1694
RE: Core Team Recommendations for HTLC Parameters

This post is intended to be an open letter from the Core Team to the Committee to provide recommendations and explanations for consideration when setting the required values to activate HTLC functionality included in the BitShares 3.0.0 Protocol Upgrade Release on 23 APR 2019. Implementation of BSIP44 introduces the following Committee-controlled chain parameters and fees [1]. The Core Team intentionally left the fees and parameters blank in the code.  Only the Committee may set (and modify as needed) these protocol parameters. The Core Team offers recommendations denominated in USD, allowing the Committee to convert to BTS using their established process.

Chain Parameters for HTLC:

max_timeout_secs
This is the maximum time the HTLC my live before the funds revert to the sender. In Bitcoin, this can be any time in the future. For BitShares, we recommend 2592000 seconds (30 Days).

While active, these contracts remain in RAM. Allowing an indefinite lifetime to the contract somewhat defeats the purpose of an HTLC and unnecessarily uses a valuable system resource. It is believed that most HTLCs will live around 6 hours. It is believed that 30 days will easily cover most known use cases.

max_preimage_size
If the contract is redeemed by providing the preimage, the contract is no longer in RAM. However, the preimage is stored in the blockchain. This parameter limits the size of the preimage that can be used to redeem an HTLC.

It is believed that the vast majority of preimages will be 256 bytes or 512 bytes which provide sufficient entropy for security. We recommend 10kb initially.

Note: Higher per-kilobyte fees should help mitigate the use of large preimages. Preimage size is a tiered calculation where bytes 1-1024 are included in the minimum fee of 1 kilobyte and a preimage of 1025 bytes would calculate in the second tier of 2 kilobytes.

Fees for HTLC:

htlc_create_operation::fee
Creating an HTLC has two component fees: a fixed fee to execute the operation and a variable daily fee to store the contract in RAM. Our recommendation is to keep the total cost of a single day HTLC near the cost to execute the transfer operation.

We recommend setting this fee to  $0.001 USD (a tenth of a cent) as the fixed component and using the fee_per_day below to equate to near the transfer operation fee for a single day HTLC.

htlc_create_operation::fee_per_day
These contracts sit in RAM until they are redeemed by either party. Memory is a limited resource, and should be considered when setting fees for HTLC. It is envisioned that the typical HTLC will be less than 1 day and thus pay the minimum cost of one fee_per_day. To encourage adoption of this technology we feel $1 USD/month to hold open an HTLC is sufficient. We recommend $0.033 USD per day.

htlc_redeem_operation::fee
The redeem operation also has a pair of related fees: operation fee and fee_per_kilobyte. Similarly, we recommend these fees be nominal for the fixed component and quite large for the variable component, as this requires permanent storage space within the blockchain to retain the preimage.

We recommend setting this fee to $0.001 USD (a tenth of a cent) as the fixed component and using the fee_per_kb below to encourage appropriate use of the blockchain resources.

htlc_redeem_operation::fee_per_kb
The preimage size is known up-front, so a redeemer can calculate their total cost of redemption before the preimage is known. Hence, if redemption cost is a deciding factor as to whether to perform the transaction, the total cost can be calculated.

We expect most HTLC transactions can be secured with a preimage well under 1kb, the current minimum fee tier. 512 bits or even 256 bits provide adequate entropy. If large preimages are desired, a large fee will be charged.  We recommend $0.10 USD as the initial fee per kilobyte.

htlc_extend_operation::fee
This operation allows the HTLC to be extended to up to the maximum_timeout_seconds defined above. Allowing indefinite length contracts. It is recommended to match the fixed creation fee defined above.

htlc_extend_operation::fee_per_day
Similarly, we recommend to match the create fee_per_day defined above.

Stakeholder Proposals / [Worker Proposal] Core Team 2019
« on: January 31, 2019, 09:00:04 pm »
BitShares Core Team Budget Worker Proposal - 2019

* Author: Ryan R. Fox ("fox")
* Complete Document: Steemit Post.
* 国语翻译 Mandarin Translation: TBD ("TBD")
* Accounting: Provided by BBF

Intent

* Provide sustainable protocol development funding for the BitShares Core Team
* Operate as a multidisciplinary collaborative team to benefit the BitShares decentralized autonomous community (DAC)
* Engage the community, regulators and public as the authoritative source for protocol development and information

Background

This budget proposal represents a follow on to the efforts established and executed by the
BitShares Core Team in 2018. It seeks to continue funding the development efforts related to the core protocol and expand its scope within the DAC to deliver greater outreach throughout 2019. The Core Team is responsible to our DAC to transparently deliver a secure protocol, collaborate on research, prioritize innovative features, and engage our Community and the public toward increased protocol adoption.

Worker

This is a _Budget Worker Proposal_ which funds the following effort areas through calendar year 2019:
* BitShares Core Development
* Collaboration Tools
* Conference Participation and Community Engagement

This Worker funds a not to exceed budget for ideation, collaboration, development and defense of the ideas, engagements and implementations required to advance the BitShares Project. Individuals supported by funds from the budget occupy a defined set of Core Team Roles at specific rate valuations detailed in _Table 2._ below.

BTS are collected into the "workers.bitshares.foundation" account which is a multi-sig account controlled by "BitShares Blockchain Foundation" and owned by "committee-account" using the Budget Worker Model which provide:

* Transparent accounting provided by the BitShares Blockchain Foundation
* Invoice review, approval and remittance within 5 business days
* Compensation remitted in a viable SmartCoin (i.e. bitCNY)
* All accumulated and unallocated BTS returned to the Reserve Pool at the conclusion of the Worker

As the team size scales or BTS token valuations fluctuate, subsequent Worker(s) will be offered to fully fund the Intent.

Core Team Scope

The primary focus of the Core Team remains maintenance and development of the core protocol and oversight of the BitShares Improvement Proposals (BSIP) process. The Core Team will continue to liaise with the BitShares UI Team, and other community lead efforts maintained within the BitShares Organization on GitHub. The Core Team continues to guide Community Contributors toward promotion into open Core Team Roles through the Community Claims program detailed below.

Collaboration tools will continue to include software tools and server infrastructure to support development and testing efforts. The bitshares-core GitHub repository remains the primary source for our planning, discussion and deliveries. The Core Team participates with the UI Team and BitShares Committee to manage access within the BitShares Organization on GitHub.

Attendance and speaking engagements at relevant international conferences, hackathons and events remain an important component of the Core Team's dedication to community outreach. We gather for in-person meetings prior to each conference and hold remote planning meetings throughout the year.

Expanded Core Team scope for 2019 will include:
* Participation in one (1) additional international conference
* Multilingual information gathering and dissemination (English and Mandarin)
* Designate the Development Spokesperson(s) for public engagements

General Discussion / BitShares Core Release 2.0.181105
« on: November 05, 2018, 07:28:03 pm »
BitShares Core Release 2.0.181105

Please read the Steemit post for proper links:
https://steemit.com/bitshares/@fox/bitshares-core-release-2-0-181105

Get the software here:
https://github.com/bitshares/bitshares-core/releases/tag/test-2.0.181018

The BitShares Core software has been updated to the 181105 Feature Release. The Core software is used by validation nodes which perform consensus of all transactions on the BitShares blockchain. This release includes new features, optimizations, and bug fixes but does not include any changes to the consensus protocol.

No action is required if you do not operate a validation node or the command line interface (CLI) wallet.

Numerous performance improvements have been made to the software that will benefit all operators of validation nodes including block producers, seed nodes, and API nodes, especially those using the Elasticsearch plugin.

Documentation for BitShares developers may be now be found at the new BitShares Developer Portal (https://dev.bitshares.works).

Who Should Upgrade?
No upgrade is required by any operator of a validation node. Yet many operators will benefit by upgrading.

All operators will benefit from performance improvements (915, 1327, 1359) and fixes (1024, 1203, 1286, 1325).
Operators of block producing nodes will benefit from performance improvements (1251), safety measures (1252), and fixes (1266, 1332, 1364).
Operators of API nodes including Elasticsearch APIs will benefit from improvements to data availability (1351, 1352) and performance (1049, 1271, 1356).
Users of the command line interface (CLI) wallet will also benefit from improvements (1195, 1248).
Upgrade Process
Precautions
Precaution 1
Operators of API nodes that service client software that expect to receive updates about all data on the blockchain by default (such as BitShares Reference Wallet before 180401), as opposed to narrowly subscribed data, should ensure that their API nodes are configured with the enable-subscribe-to-all set to true due to Pull Request 1049.

BitShares Core Team Budget Worker Proposal - 2018 (1.14.99)

* Author: Ryan R. Fox (`"fox"`)
* [国语翻译](mandarin_translation.md) Mandarin Translation: 招木 (`"Zhaomu"`)
* Article published on Steem blockchain http://bit.ly/CoreTeam2018
* Worker published by BitShares Blockchain Foundation 201803-bitshares-core
workers.bitshares.foundation (1.14.99)



Intent

* Establish a budget to sustain the development efforts of the BitShares Core Team
* Define a framework for the Core Team to collaborate within
* Provide transparent delivery of BitShares development efforts to the community

Background

BitShares Core software is currently maintained by individuals either volunteering their time or
receiving funding through distinct short-term worker proposals. The BitShares Community has
recognized the need for organized development efforts to increase the utility of our platform.
There is a large backlog of ideas and requirements lacking prioritization, including feature
enhancements, bug fixes, and BSIPs. Therefore, proposed is the establishment of a long-term,
professional, global team dedicated to cohesive and comprehensive development efforts delivered
transparently.

Worker

This is a Budget Worker Proposal which provides partial funding through calendar year 2018 for:
* BitShares Core Team Roles
* Collaboration Tools
* Development Initiatives

This Worker funds an _initial_ Core Team at reduced hours to mitigate draw on the reserve pool
and support bootstrapping efforts. Subsequent Worker(s) will be offered to fund the team as it
scales up. This Worker intends to work in concert with the existing development resources including
Abit, Alfredo Garcia, and the UI Team, led by Bill Butler.

BTS are collected into the `"workers.bitshares.foundation"` account which is a multi-sig account
controlled by `"BitShares Blockchain Foundation"` and owned by `"committee-account"` using the
Budget Worker Model [5]:

* Transparent accounting provided by the BitShares Blockchain Foundation [6]
* Submitted invoices reviewed, approved and remitted within 5 business days
* Compensation paid in bitUSD (according to the rules set forth in [5])
* All unused accumulated BTS returned to the Reserve Pool at the conclusion of the Worker [5]

_Initial_ BitShares Core Team

The initial Core Team is comprised of community members who have demonstrated their ability to work
with Graphene-based code, contribute to this community with thoughtful leadership and share a
dedication to the BitShares ethos. Initially, the team is a skeleton, with many contributing to
multiple roles and at reduced weekly hours as represented in _Table 1_ Each team member is focused
on returning more value to the BitShares platform than is drawn from the reserve pool.

The initial team is estimating 54 hours of weekly effort. This Worker proposes to budget $15,000
for a team delivering approximately 100 hours weekly to support conservative growth. Demonstrated
results will warrant subsequent Worker(s) to budget for additional team members and weekly hours.

_*Abit and Alfredo intend to complete their existing Workers. Their contributions as part of the
Core Team will initially be at the reduced hours above, then expected to increase similar to their
existing Worker.
**Additional hours for all roles remain available at this time. Please contact
[email protected] for additional information._

BitShares Core Team

The BitShares Core Team is a self-organizing agile-principled team focused on delivering regularly
scheduled releases and ad hoc bug fixes for the BitShares Core software. The actual number of
contributors and roles may vary within each development cycle (described below), leading to
variations in weekly compensation per contributor. The team has discretion in allocating resources
to meet the needs of each development cycle.

Producing reliable and secure software at scale requires ideation, organization, definition,
prioritization, development, testing and documentation. The ideal team composition includes roles
specializing in each of these functions and capable of contributing to many. The goal of a highly
functioning team is to fully utilize each individual's effort and together maximize their
collective output.

Development Cycles*
  * Feature Release (non-hard fork):
    * Three-week sprints
  * Core Release (Hard Fork):
    * Twice annually: first Thursday of June & December

_*Subject to change upon consensus of Core Team Members_

A typical Feature Release will likely span three weeks from planning thru tested and delivered
software, called a sprint. Many agile principals will be adopted by the Core Team, but do not
expect a strict scrum practice. This is a global team, so a formal daily standup is unlikely. One
should expect asynchronous communication within various collaboration tools keeping the team
informed of progress, plans and problems. The community are our stakeholders; we look to them for
ideas, enhancements and identifying bugs, then organize these into a backlog for future
development. The Coordinator facilitates the prioritization of the backlog items based on feedback
from the stakeholders and the Core Team. The team will keep the stakeholders informed of
development progress throughout the sprint.

At the beginning of a sprint cycle the Core Team meets to review the prioritized backlog and
identify the highest value items that each can contribute to, within the established time block.
Many features have dependencies and cannot be implemented within a single sprint. Therefore, the
team will create tasks, a subset of the feature, that can be delivered on time. A task may be
researching and defining requirements to be implemented later. A task may be writing a test case,
or perhaps implementing only a subset of a given requirement, or even documenting how existing code
functions. The team will maintain a sprint backlog comprised of the tasks selected from the project
backlog. Completing each of these tasks results in incremental value added to the project. Testing
is performed throughout the sprint to ensure functioning code from each increment.

As the sprint nears completion, the Core Team will begin release planning. They will select which
tested increments are ready to be included in a release candidate. This will be deployed to a
staging network for final validation. A release will be tagged within the bitshares-core GitHub
repo along with release notes. The team also produce stakeholder documentation detailing resource
allocations and budget consumption.

The final steps of the sprint include a retrospective look at how the team performed. Here we
reflect on our original estimates, the delivered increments and what contributed to our successes
and shortcomings. We will use insights gained from the retrospective to improve in the next sprint.
The following day we immediately begin our next sprint cycle.

Bounty Process (Implicit Budget)

The BitShares Core Team maintain a prioritized project backlog of ideas, enhancements, bugs and
BSIPs which they select from for their development sprint. The community is encouraged to comment
on the items to aid in refining requirements and guide prioritization. Effort estimates are first
assigned to the highest value backlog items. Unassigned and estimated project backlog items are
available for ad hoc _bounty_ development. Successfully completing ad hoc bounty items is a primary
consideration for an invitation to join the Core Team on a future sprint.

The Core Team encourages ad hoc code contributions of estimated project backlog items from
community members and will compensate successfully merged code based on those estimates. The
Coordinator will facilitate onboarding new community contributors to _claim_ a backlog item and
implement a solution that fits within the broader architecture design defined by the Lead
Developer. Care must be taken to ensure effort is not duplicated and can easily be merged within a
future sprint. Claimed items that become a dependency of a sprint may be recalled by the Core Team
to facilitate feature delivery. Compensation for a partially completed increment will be evaluated
by the Lead Developer.

Compensation for a successfully merged _bounty_ item is drawn from the excess _implicit_ budget
capacity within _Table 1_ when any Core Team Role is not fully allocated. The specifics for the
bounty process is still being revised (note: it is largely based on the process in use by the UI
Team).

BitShares Core Team Framework:

Accountability
* Maintain timely collaborative communications with each BitShares Core Team Member
* Participate in at least two of three weekly Collaboration Sessions (see Coordinator description)
* Target a majority of your weekly hours between Tuesday - Thursday
  * Facilitates ad hoc collaboration
  * Facilitates healthy work/life balance

Transparency
* Maintain working increments within Community facing collaboration tools
* Maintain timely updates within Community facing collaboration tools of work in progress and development priorities

Delivery
* Deliver the highest value work first
* Favor release schedule over feature completeness (see Development Cycles)

BitShares Core Team Member 'Contract Work' Guidance:

This section is to be considered guidance, not a legal statement. The BitShares
Decentralized Autonomous Community (BitShares DAC) controls the funds collected
by this Budget Worker and are issued as compensation to individuals performing
agreed work as described elsewhere in this document. Effort contributed by
individuals is considered by personal commitment as no formal employment
contract is intended or able to be formed between BitShares DAC and the
individual worker. Neither the BitShares Blockchain Foundation (BBF) nor the
BitShares Committee or any individual serving those entities are to be
considered employers of any agreed contribution. No BitShares Core Team Member
or Role is considered the manager or the employer of any individual person. Any
compensation received from the BitShares DAC might be considered earned income
for individual persons involved in their individual situation and may be
subject to tax reporting by the recipient. Neither BitShares DAC, nor the
BitShares Blockchain Foundation, nor BitShares Committee, nor the Coordinator,
or any Core Team Member will neither carry responsibility, nor command, nor
issue, nor prepare any document, including tax documents, to any entity or
natural person. All effort performed is a contribution to the BitShares DAC
adhering to its MIT license.

Each Core Team Member is encouraged to contribute in a responsible way with
respect to a work/life balance and legal employee engagements he or she might
have entered into, or enter, with an employer.

Alfredo Garcia - Core Developer

I recently began my second 6-month Worker as a BitShares Core Developer [12]. Mainly I focus on the
bitshares-core software by implementing features, fixing bugs, testing, maintenance, etc. [13]. I
also develop outside the core tools for other developers and final applications for the BitShares
community. [14]

Bill Butler - UX/UI Liaison

I lead the BitShares UI team and have extensive industry experience: Founded an ISP in 1993,
NodeJS, Angular, PHP, CouchDB, SQL. UX/UI Experience [16]. I am currently VP Engineering for a

Development Initiatives

The Initial Core Team has identified in _Chart 1_ a set of Initiatives to research, define and
develop as part of their 2018 Roadmap. A detailed Roadmap will be a deliverable of this Worker for
Community review. An 'Ideas Portal' will also be maintained to incorporate Community priorities
into the Roadmap.

Caveat: The Core Team cannot commit to deliver fully implemented solutions for all identified
Initiatives. The intent here is to provide guidance at the outset, realizing the Core Team
continuously evaluates and prioritizes new issues ongoing.

* Interchain Communication
  * Atomic Cross Chain Transactions (ACCT)
  * EOS.IO Integration Report
  * Trustless Gateway
* Market Mechanics
  * Market Engine Improvements
  * Maker/Taker Model
  * Bancor Protocol
* Consensus & witness_node Enhancements
  * Database Storage Options
  * Installation scripts / environments
* Confidential Transactions / Confidential Assets
* Hardware Wallet Integrations
* API & cli_wallet Enhancements
* Community Engagement
  * Vote Decay
  * Fee Schedule based on Market Pegged Assets
* Refine/Prioritize Existing BSIPs

Duration and Pay

This proposal will last for roughly 44 weeks, starting from 1st March 2018.

Payments:
* Invoices from Core Team Members will be submitted to the Coordinator by Monday 12:00 UTC for work
performed thru Sunday 23:59 UTC of the previous period
* Coordinator will review and approve submitted time sheets, then forward an invoice to BitShares
Blockchain Foundation for release of funds from escrow to `"bitsharesdev"` account for remittance to
contributors
* Coordinator will review and approve vendor invoices, then forward to BitShares Blockchain
Foundation for direct payment to vendor

Calculation:
* 3.9761 BTS/bitUSD = Settlement price of bitUSD at the moment of writing (2018-02-16)
* 2.5 = Collateral multiplier to cover market fluctuations and borrow with 2.5x collateral, as needed
* $2,416 USD/day * 3.9761 BTS/USD * 2.5 collateral multiplier ≈24,016 BTS/day

USD payment will be in bitUSD with method developed by the BitShares Blockchain Foundation [5].

General Discussion / Request - Wallet API Access Using curl
« on: May 06, 2016, 04:06:34 am »
May I request some assistance with the syntax to access the wallet-api using curl (not wscat)? I have reviewed the the following documentation:
http://docs.bitshares.eu/api/websocket.html#call-format
http://docs.bitshares.eu/api/wallet-api.html#wallet-calls

I am successful requesting get_dynamic_global_properties:
Code: [Select]
curl --data '{"jsonrpc": "2.0", "method": "call", "params": [0,"get_dynamic_global_properties",[]], "id": 2}' http://127.0.0.1:8090/rpc
But fail requesting for help:
Code: [Select]
curl --data '{"jsonrpc": "2.0", "method": "call", "params": [0,"help",[]], "id": 2}' http://127.0.0.1:8090/rpc
Thanks in advance for the assistance,

The BitShares on Ubuntu 15.10 template for Microsoft Azure Blockchain as a Service (BaaS) is now live:
https://github.com/Azure/azure-quickstart-templates/tree/master/bitshares-ubuntu-vm

You may search for BitShares at the Azure Quickstart Templates site:
https://azure.microsoft.com/en-us/documentation/templates/

README.md:
# BitShares Blockchain Node on Ubuntu VM

This template delivers the BitShares network to your VM in about 15 mintues (PPA install).  Everything you need to get started using the BitShares blockchain from the command line is included.
You may select to build from source or install from the community provided Personal Package Archive (PPA).  Once installed, the 'witnes_node' will begin syncing the public blockchain.
You may then connect via SSH to the VM and launch the 'cli-wallet' to interface with the blockchain.

<a href="https://portal.azure.com/#create/Microsoft.Template/uri/https%3A%2F%2Fraw.githubusercontent.com%2FAzure%2Fazure-quickstart-templates%2Fmaster%2Fbitshares-ubuntu-vm%2Fazuredeploy.json" target="_blank"><img src="http://azuredeploy.net/deploybutton.png"/></a>

# What is BitShares?

```
BitShares is an industrial-grade financial blockchain smart contracts platform.  Built using the latest in
industry research, BitShares delivers a decentralized financial platform with speeds approaching NASDAQ.
```

# Template Parameters

When you click the Deploy to Azure icon above, you need to specify the following template parameters:

* `adminUsername`: This is the account for connecting to your BitShares host.
* `adminPassword`: This is your password for the host.  Azure requires passwords to have One upper case, one lower case, a special character, and a number.
* `dnsLabelPrefix`: This is used as both the VM name and DNS name of your public IP address.  Please ensure an unique name.
* `installMethod`: This tells Azure how to install the software bits.  The default is using the community provided PPA.  You may choose to install from source, but be advised this method takes substantially longer to complete.
* `vmSize`: This is the size of the VM to use.  Recommendations: Use the A series for PPA installs, and D series for installations from source.  Notice: Once the blockchain is synced, resize your VM to A1, as the BitShares witness_node requires a small resource footprint.

# Getting Started Tutorial

* Click the `Deploy to Azure` icon above
* Complete the template parameters, choose your resource group, accept the terms and click Create
* Wait about 15 minutes for the VM to spin up and install the bits
* Connect to the VM via SSH using the DNS name assigned to your Public IP
* Launch the cli-wallet: `sudo /usr/bin/cli_wallet --wallet-file=/usr/local/bitshares-2/programs/cli-wallet/wallet.json`
* Assign a secure password `>set_password use_a_secure_password_but_check_your_shoulder_as_it_will_be_displayed_on_screen`
* `ctrl-d` will save the wallet and exit the client
* View your wallet: `nano /usr/local/bitshares-2/programs/cli-wallet/wallet.json`
* Learn more: [http://docs.bitshares.eu](http://docs.bitshares.eu)

BitShares 0.9.3 has been released:  https://github.com/bitshares/bitshares/releases/tag/bts%2F0.9.3

This release will stop block production on October 13th at 9AM EST and adds new API calls for exporting the wallet for Graphene.   

If delegates do not wish to stop producing blocks at the stated date/time then they need not upgrade.   If you are a seed node then you do not need to upgrade. 

All delegates committed to transitioning from the existing BitShares network to BitShares 2.0 should upgrade their node(s) to 0.9.3, publish their version to the blockchain and be ready to produce 2.0 blocks using the Graphene codebase upon launch 13 OCT 2015. 

Stakeholders should watch each delegate's published versions (both active and stand by) and their statements below, then adjust their votes to support delegates that (will) produce blocks for the network they intend to follow after the announced hard fork time.  An updated list is visible at the bitsharesblocks website [1].

Stakeholders should take care to ensure their wallet client software and that of the third parties they may interface with also follow the chain of your choice after the hard fork.  These choices are yours to evaluate and act upon.  Decentralization welcomes you.

Technical Support / Understanding Graphene: Shared Secret Key
« on: September 02, 2015, 02:42:00 am »
Does the Graphene protocol make use of a shared secret key by the set of block producing witnesses in each round?  If yes, please describe the protocol for generating the shared secret key and what current and potential function(s) is served by its use.  References within the code are also appreciated.

Requesting assistance with building Graphene on Ubuntu 14.04LTS.  I have reviewed the Build Ubuntu documentation for Graphene [1] and taken care to verify Boost 1.57 is referenced within the CMake script.  However, the build fails within 'project_secp256k1' with the output:
Code: [Select]

I did review closed Issue #76 [2] which references this library and similar build issues.  Those changes were merged into Master three weeks back, so perhaps this is new, yet related.

Please help me understand what impacts, if any, the BitAsset 3.0 proposal has on existing User Issued Assets. 
  • What is the relation between BitAsset Market Issued Assets, User Issued Assets and BitAsset 3.0?
  • What are the potential risks to existing User Issued Assets (issuers and holders) when BitAsset 3.0 enters the market?
