1  Bitcoin / Bitcoin Discussion / Using crypto to help Hong Kong on: August 19, 2020, 01:11:22 AM
Anybody else working on this? Some Bitcoin community members in Canada have gotten involved due to the high number of Hong Kong expatriates here... they're helping them with security issues. The most notable beneficiary of support has been Alliance Canada Hong Kong--Google them to find lots of news results. See this page about the Initiative. Totally non-profit stuff
2  Bitcoin / Meetups / CoinFest 2021 on: August 15, 2020, 11:00:58 PM
COVID19 threw CoinFest for a loop in 2020, forcing the cancellation of all physical events for the first time in our years-long history. We still had to celebrate the usual date in April, however, so we did a big virtual event in Decentraland in partnership with We got media attention from multiple outlets and made a promo video you can watch.

Things are still up in the air for CoinFest 2021, but we are optimistic that physical gatherings will be able to resume in April. Activities originally intended for CoinFest 2020 will occur as previously planned. If the global health situation does not go well, we will still do another event in Decentraland either way. We will provide more information in the next couple months.
3  Bitcoin / Meetups / CoinFest 2020 on: May 02, 2019, 04:38:27 AM

CoinFest 2019 was a blast, as usual. You can see all the cool events we had at

CoinFest 2020 has already been announced. So far, the cities planning events are all the same as last year, but we are encouraging people to step up and organize events in their cities, too. We have 11 months to plan, so it seems likely some will emerge.

Some important updates:

  • The date of CoinFest will be May 30 - April 5. Typically it is the first full week (Monday - Sunday) of April, but next year, that will not coincide with Satoshi's rumored birthday, or the Bitcoin Wednesday event in Amsterdam. This misalignment will occur every several years, at which points CoinFest will be shifted back exactly one week.
  • We now tolerate people organizing CoinFest events that are not free to attend; however, they will be unable to claim grant funding from the global CoinFest fund, as free events are still encouraged. This decision was made according to popular opinion following polls. CoinFest events are still expected to be non-profit, however, and will not be listed on if we suspect the organizer is directly profiting.
  • We are upgrading the multisig wallet which communally controls the global CoinFest fund. Previously, we used Copay, but they handled the Bitcoin Cash fork very poorly, such that we lost over $1000 worth of crypto due to no technical error on our organization's part. Also, Copay only allows 6 signatories max, but we have more organizers than that. Our new Electrum wallet will be 4-of-10, and set-up should soon be complete.
4  Bitcoin / Meetups / CoinFest 2019 on: March 15, 2019, 09:29:47 AM

It's about that time of year, again, where cryptocurrency enthusiasts around the world unite in thanks and celebration. It's been a long, hard winter for us all, but now is the time to put our differences and troubles aside and remember the great teachings of Satoshi.

For those who aren't in the know, CoinFest is an annual decentralized convention that occurs simultaneously around the world. Run by volunteers as a non-profit and funded by generous sponsors, it has always been free to attend and always will be. It also only holds crypto assets and occurs at venues that accept or support cryptocurrency (such as by accepting it for payments).

Some highlights for this year:

  • CoinFest Vancouver will have a Mass Blockchain Wedding and a Blockchain Gaming Expo.
  • CoinFest UK in Manchester is now three days long! Expect hundreds of attendees, as usual.
  • CoinFest is now scheduled to occur at 5 different cities across Africa. The main event in Nigeria will now be two days long.
  • All the usual festivities in the Netherlands

5  Bitcoin / Development & Technical Discussion / How Forks Ruin Multisig: a Cautionary Tale on: August 07, 2018, 03:38:22 PM
As the founders of CoinFest, we were one of the earliest to experiment with real use cases for large multisig wallets. We were even 10-of-15 at one point back when CoinKite was still around. Things got complicated sometimes, but we never had to face losing any funds... until the Bitcoin Cash fork.

Splitting Bitcoin Cash was somewhat confusing ordinarily, but a massive headache with multisig wallets. It took Copay (our current multisig wallet) a while to enable it in their app, and meanwhile we sat on a nice stash of untouchable coins. Annoying.

Eventually, we got around to trying to split the coins, and then things got even weirder. All signatories have now confirmed the Bitcoin Cash wallet, but because there's a lot of us and a couple had technical difficulties, there was a significant window of time between the wallet's initiation and the final confirmation. In that time, Bitcoin Cash underwent a major update and I had to restore to a new phone (old one stolen) with my back-up; this appears to have had the effect that some signatories can see each other and others can't, and the wallet set-up cannot complete.

BitPay says we need every signatory's back-up to fix this, but one signatory is now refusing. He's essentially acting maliciously, but he also has a point: multisig wallets are intended for us to not have to trust each other or give up our back-ups while having shared control of funds. What we're asking is antithetical to the concept of Bitcoin, but we need him to acquiesce or else we lose all the BCH.

Moral of the story: be careful out there, guys. Also, anybody got any multisig wallet recommendations that might save us, here?
6  Alternate cryptocurrencies / Service Announcements (Altcoins) / Blockchain Gaming ( on: May 21, 2018, 02:14:31 PM

Blockchain-based video games have been a pet project of mine for years, now, ever since I wrote about them for Bitcoin Magazine in 2014. I've always loved video games, and I went on to write for NewsBTC about Moonga, Munnecoin, Spells of Genesis, Huntercoin, Beyond the Void and other news and analysis. There are also interviews on BlockTalk, the Crypto Show and Bitcoins and Gravy, and I've spoken at a few conferences on the subject.

I acquired (and related domains) early on, hoping everybody else would love the blockchain gaming concept as much as I did. The industry was still nascent, however, and I lacked resources and was busy with ESL Coin, so I left it as a placeholder explaining blockchain games and started to slack on the updates when ESL Coin really picked up.

Recently, however, I've partnered with a couple friends, and we have established a growing team to take things to the next level. We aim to make our website the ultimate community resource for blockchain-based video games, and are redesigning it to enable community-generated content in addition to in-house reviews and interviews. We're also going to be heavily involved with events, such as the upcoming Blockchain Game Summit, and have sections for news, FAQ and guides.

We already have a very active community on Facebook and Twitter and are rapidly expanding our variety of social media and communication channels. We welcome all who wish to join our community, especially those who want to contribute content or join our website's core team. Stay tuned for news!

Anyone else going? The highlight will be Andreas Antonopoulis speaking, of course, but I'll also be talking about blockchain-based video games and setting up a booth for ESL Coin. Some of my friends are speakers/exhibitors, as well.
10  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] Prime-Ex Perpetual - Bringing Real Estate Profits to YOU! on: September 04, 2017, 08:29:32 PM
There's a new real estate coin in the works. Most experts from the cryptocurrency industry have been nervous to try it (regulators), but these guys seem pretty confident they won't have any problems.

Translated announcements:


11  Economy / Reputation / Sued By Onecoin on: August 23, 2017, 01:50:21 AM
CoinFest organizer Tim Tayshun is BEING SUED by a Onecoin shill in federal court for 77 counts of defamation. I don't think Onecoin could possibly win in any reasonable judge's courtroom, but unfortunately it costs time and money to show up and deal with it, which is why they're doing it to him (it's bullying).

We are going to use CoinFest's multisig wallet as an escrow to store funds donated for the purpose of fighting this lawsuit. In the event that more funding than necessary is received, all leftovers will be kept by CoinFest to be used for educating people about real cryptocurrencies that aren't Ponzi schemes, maybe even an anti-shitcoin workshop if somebody volunteers to organize it.

You can find our donation address and QR code in this interview on the subject. Please spread the word and feel free to donate... conferences such as CoinFest can only remain open and permissionless if the community is active about fighting scams, which will attempt to infiltrate us.

12  Economy / Scam Accusations / SCAM ALERT: Etctrade on: August 19, 2017, 05:10:18 AM
Hey guys, I apologize if this is in the wrong format or if Etctrade has already been brought to the forum's attention. I just found out about it, myself.

Basically, Etctrade is founded by the same people as Ethtrade, and therefore a scam. I have information from a previous investigation indicating this to be the case, and also, it looks kind of obvious, anyways. The names are nearly the same, and the business models look the same, and the real team is unknown. If you run one of those websites for reviewing scams, please add this one before they manage to start up again (if people are that stupid).
13  Bitcoin / Meetups / Grand Opening of Vancouver's New Blockchain Hub on: August 11, 2017, 05:21:59 AM
The Vancouver Bitcoin community has long been proud of our underground hack space known as DCTRL, and it continues to serve us well. However, some people had longed for a more professional and above-ground (pun intended) venue, more like what they have in Toronto and Montreal.

With that in mind, has opened up a new blockchain hub in downtown Vancouver. It has lots of space and a float tank (they're popular around here), and their first event later this month will have free food and beer!

14  Other / Archival / [ANN] Ethereum Plus (ETHP) - ICO Starts from August 15th on: July 28, 2017, 01:18:11 PM
This ICO is almost certainly a scam. I did not know; sorry for sharing it to this forum. Please see the first couple pages of this thread for info:
15  Bitcoin / Meetups / CoinFest 2018 on: June 06, 2017, 09:49:23 AM
In keeping with tradition, CoinFest 2018 will be held on the first full week (Monday-Sunday) of April, which is April 2-8. We still need to update the CoinFest 2018 page... let us know if you want to organize a CoinFest in your city so we can add it to the map. Supporting organizations and sponsors on the Homepage will soon be reset, so anybody who wants to sponsor us this year should please reach out, as well.

While everyone waits for updates about that, check out our Previous Events page, which now shows all the cool stuff we did at this year's CoinFest. Also, we've successfully created our new 3-of-6 multisignature wallet and transferred to it all remaining funds from the old one... we now have over $3000 worth of BTC already in store, as the updated Transparency page now shows.

16  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] ESL Coin & Try English App (ICO coming) on: June 05, 2017, 12:26:15 PM

This is an idea I’ve been sitting on for a long time now, patiently waiting to see if and when the stars would properly align. Over the years, I helped Factom, DECENT, Spells of Genesis, Synereo, Autonio and others achieve success with the launch of their coins, and while I learned a lot along the way, I’ve secretly been waiting for the opportunity to organize one, myself, leveraging my pre-crypto background.
I originally worked in the ESL industry, which stands for English as a Second Language. English-speaking populations constituted over 31% of the world’s GDP when measured in 2015 due to their size and relative affluence. As such, they are the primary target of consumer export-driven economies, causing English proficiency to be viewed as a sign of and gateway to professional success.
That means there is a huge demand for English education around the world, with over 1 billion students and almost double that projected by 2020. Most study in their home countries with the increasing aid of technology, yet many others travel to language schools in English-speaking countries, utilizing homestays and other tailored services. In the Canadian province of British Columbia alone, this has generated over $3 billion in annual revenue.
Unfortunately, the people involved have been generally ignorant about and even skeptical of cryptocurrency. Now that there have been numerous successful ICOs, however, and mainstream companies are considering them, I finally managed to convince the key players necessary of the pressing utility of blockchain integration. Soon, a plan was formed.
Gathering a couple colleagues whom I’ve known for years, I then reached out to some of my most trusted Bitcoin contacts, who have proven records of success in complementary areas. Together, we are embarking on a project that will enrich both the ESL and cryptocurrency communities while spreading blockchain technology further into the mainstream. Here are the details.

The history of our ESL group is intertwined with the history of Bitcoin, itself. It started as a small Meetup in Vancouver for ESL students to practice speaking with each other and local Canadians, making friends along the way. Over time, however, the Meetup grew, and it now boasts over 8,000 members who meet almost every day of the week.
With it came many connections to local event venue owners, which I (as a Co-Organizer) used to spread Bitcoin adoption. The world’s first Indian restaurant to accept Bitcoin was one of our meeting spots, and the cafe which houses the world’s first Bitcoin ATM is our most popular location. It’s safe to say it has been integral to the success of the Bitcoin Co-op and Vancouver’s cryptocurrency community.
That and other circumstances caused us to focus more on other projects for a while, but Conversational English continued to grow until our Facebook page caught international attention. Despite expending relatively little effort and $0 on advertising, we’ve reached over 21,000 likes, and our content frequently goes viral. Eventually, I was forced to create online chatrooms for us by popular demand, with most of the activity on WhatsApp and KakaoTalk.
We are expanding to other platforms, but our group will soon grow too difficult to manage. What’s needed is a multi-purpose platform specialized for the ESL community, which uses cutting-edge technology to automate some of our responsibilities and keep everything under one roof. In the process, we will use blockchain technology to build a decentralized ESL economy that gives back to the community.

Mobile phones are the future of user engagement, especially in developing countries where home computers are less common. It’s evident from the success of our WhatsApp & KakaoTalk groups (relative to Skype) that this is true for ESL students, as well, and so while we intend to produce a desktop version, the mobile app will be our primary focus.

Most of these features are currently provided by very high-paid consultants, who connect students, teachers and other clients in the industry. Our app will cut out the middlemen, utilizing small fees to fund its operational cost. Additionally, to satisfy ESL students’ demand for native English speakers to practice with, their participation in chatrooms and at events will be incentivized by very small payments (bots are ineligible).
As Try English is not just intended for the cryptocurrency community, it will be designed based on the assumption that users know nothing about blockchain technology and have no interest in it. In the background, however, it will be gradually decentralized over time, and strategically-placed links will lead many to learn more about the blockchain revolution. We are developing separate websites and marketing campaigns.

All transactions will, of course, be paid in ESL Coin, which will also be the medium of exchange for related goods and services. This makes it an access token, required to fully utilize the ESL Network and any apps built on top of it. It will also utilize blockchain technology for non-currency applications, particularly for the reputation system and user validation.
Users familiar with cryptocurrency will be able to deposit and withdraw ESL Coins to and from their Try English accounts as they would any other, and wallet support will be provided. Users not familiar, however, will buy ESL Coin directly in the app with fiat. They will see it as analogous to something like Facebook Credits or one of the many centralized tokens built into mobile games you can buy to accelerate the gameplay.
ESL Coin will be built on top of the Ethereum blockchain (at least for now). There are multiple reasons for this decision:
  • We need micro-transactions immediately and cannot wait for Bitcoin’s scaling issue to inevitably be resolved
  • It specializes in the features required and a lot of development has already been put into it, saving us time
  • It has mainstream institutional support, which is convincing to potential partners in the ESL industry
  • Immutability is not a concern for this project, as it’s apolitical. My plans to undermine the state (unrelated) are for another chain

As previously stated, ESL Coin is an access token. It draws buy support from people who want to pay for services rendered via the ESL Network, including students for tutoring and homestay operators for listing in the search engine. It does not draw buy support from unregulated revenue streams which ESL app developers control--such as the placement of graphical ads--if they choose to accept fiat directly, but Try English will only accept ESL Coin.
The total initial supply of ESL Coins will be determined by the success of the upcoming ICO, and no new coins will be created. The ESL Coins used to incentivize native English speaker participation will derive from small fees on settlement of services rendered via the ESL Network, instead, which will also be used to pay Ethereum’s transaction fees.
Although Try English will initially rely on a central server, the goal is to transition to a completely decentralized ESL economy. Therefore, Ethereum will serve as its backbone, assigning a numerical reputation to each tutor or homestay which changes according to feedback from students. Identity registration may improve users’ reputations as well as feedback from other users about them, and all are subject to banishment from the system if their conduct is reported and they reach a low enough score.
Although ESL Coin is an access token, it will be more than an appcoin. Our goal is to get everyone in the ESL industry to accept it, which we are uniquely situated to do with our resources and expertise. We may eventually pursue further ESL Coin projects, as well… the future of English education will not be centralized!

Try English will be owned and maintained by a private company, BitLingual, while ESL Coin will be under the jurisdiction of the ESL Coin Co-op. Both are operated by the same team, for now, but that might not always be true, especially if third-party developers build on top of the ESL Network. Our team:
  • Founder Andrew Wagner, founder of CoinFest & Blockchain Gaming, Community Manager at NewsBTC and a director of the Bitcoin Co-op who promotes decentralized technology
  • Chief Administrative Officer David Genest, a UBC Sauder School of Business graduate with finance specialization and over 10 years experience as an analyst for the energy sector
  • Chief Academic Officer Aldona Dziedziedko, an ESL teacher who got her Masters from UBC and is finishing her B.Ed. with minors in international education and curriculum development
  • Board Member Adam Rizvi, the founder of Crypto Bates Group and CoinFest UK
  • Board Member Brad Chun, owner of Mooti blockchain ID platform, Founder of Shuttle Fund Advisor
  • Concept Designer Isaac Nandgavkar, a dedicated crypto enthusiast who’s worked with multiple aforementioned projects

Any app developers interested in joining the team should reach out ASAP. Additionally, we are interested in hiring a developer who is versed in Ethereum smart contracts and/or an expert at cryptography in general. All other potential Try English or ESL Coin team members should please inquire.
The date and full details of our ICO will be announced soon. We're also still working on our bounty program... please be patient. Smiley

EDIT: The scope of this project has been expanded a lot since this original post. A good summary:

  • There is renewed focus on test score transmission and other academic record keeping. This required new partners, the expansion of our smart contract architecture, and a new diagram and white paper adjustments
  • We are focusing on other new decentralized services, as well. These include a decentralized application for translating content, accent reduction, and educational content registration (for IP purposes) and P2P distribution
  • We've gone the regulated route, because our home country of Canada is relatively friendly and it's important to potential partners, many of whom are publicly-funded. This means ICO backers will be KYC'd, so anonymity-seekers need to stick to decentralized exchanges (after network launch)
17  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] DAO.Casino - Blockchain Protocol for the Gambling Industry on: May 22, 2017, 11:27:41 AM

Their account isn't old enough to post [ANN]s, yet, but I wanted to help them announce this before Consensus 2017. DAO.Casino is an Ethereum-based protocol for the online gambling industry that enables interactions between all parties without the need for trust. It aims to cover not just the games and user account balances, but the gambling industry value chain as a whole.

It consists of:

  • A system that is capable of providing equally unpredictable pseudorandom numbers for games open to any game developers.
  • An automated value distribution protocol that enables a P2P markets to emerge.

Smart contracts act as autonomous agents that reward all the key contributors for their work exactly how they have been programmed: game developers, referrers and operators of independent platforms necessary for the game discovery, and those that take part in PRNG.

Obtaining randomness necessary for gambling games in a deterministic virtual machine is not a trivial task, so an economic incentive layer should be introduced. Equally unpredictable random numbers that determine outcomes in each game are provided by a bankroller panel interacting with the gaming contract.

Problems with Traditional Casino Systems

The online gaming industry has a plethora of issues that directly/indirectly originates from the concentration of trust. These issues can be anything from RNG to user balance account management and developers’ access to the market.

Here are some of the common problems experienced by the players:

  • After transferring the money to the game account, it is not credited or it is stolen;
  • After withdrawing the money from the deposit, it has not been credited to the card;
  • The player has not received the promised bonuses;
  • The player is not able to enter his or her game account;
  • Hidden fees: casinos charge a fee for the gain withdrawal;
  • The player can withdraw funds only on a certain day.

Why DAO.Casino Protocol?

DAO.Casino enables a sustainable working model which benefits all the associated parties in the online gambling business process. DAO.Casino can solve:

  • Risk of fraud on behalf of online casinos;
  • Inability to check the result of the draw;
  • High and hidden fees;
  • High entry level for the game developers;
  • High costs of running an online casino;
  • Operations overheads such as integrating payment systems & user account balance management.

Our Mission

The core objective behind the existence of DAO.Casino is to replace centralised casino models with a socio-economic protocol with no human intervention whatsoever. This decentralized system will achieve a fine balance between active participation and a fair economic return for those who participate.

For developers, DAO.Casino proposes to eliminate their need to rely on centralized casinos. Instead, the protocol makes it easier for these talented individuals and teams to monetise their work, raise funds, and expect bankrolling without paying heavy commissions.

For gamers, DAO.Casino is equally attractive, as it allows them to break free from rigged centralised online casinos. Traditional casinos are a black box; players cannot call their bluff easily, because the outcomes of each bet are calculated behind closed curtains. DAO.Casino, on the other hand, allows for transparency.

The protocol focuses on obtaining pseudorandomness in all the gaming outcomes by introducing an economic incentive layer. Here, the participants interact with PRNG contracts to ensure unpredictable pseudorandomness. In the beginning we expect existing licensed online casino operators to integrate with the protocol to reduce costs, while long-term new forms of regulations more suitable for decentralised, transparent and automated systems can emerge.

The long-term goal of the DAO.Casino project, apart from providing experimental software and implementing main protocol components, is to contribute to the development of new forms of online gambling certification. So far, gambling games on Ethereum remain in the gray legal area, but it doesn’t have to be so, since technologies such as Ethereum open up possibilities for far better customer protection and enable fair-by-design gambling.

Read our whitepaper

About the BET Token

BET is DAO.Casino’s internal token. It is used as in-game currency for all the game contracts integrated with the protocol and to power DAO.Casino reward system. In the near future, BET accounts can also be used as a reputation system and for ranking the games and the players. For example, most popular games would have more transaction history.

DAO.Casino values participation as much as it values investment, so the protocol will benefit all the parties involved in the online gambling business process. Suggested Dao.Casino reward distribution is as follows; it rewards all participants equally, however independent platform operators can choose their own reward distribution scheme (e.g. if the platform needs to incentivise more referrals but build their own games)

Game Developer: 25%
Casino Operator*: 25%
Referrer: 25%
Bankroll Backers: 25%

*Casino Operator/Platform can only be one entity. All figures are subject to change.

BET Crowdfund

The BET crowdfunding campaign is planned during Q3 2017. Dates will be announced soon.

Basically, techno-anarchists believe that advanced technology tends to have a liberating effect on society, and that we should utilize it for that purpose. Bitcoin, the blockchain, peer-to-peer networking, 3D printers, and the meshnet are all great examples. Any other techno-anarchists out there?
