Understanding DAOStack and joining a DAO

What is a DAO? A DAO stands for Decentralised Autonomous Organisation and with the invention of blockchain technology, in a nut shell has allowed a group of people to make decisions where trust is placed within the technology and the blockchain network. What is DAOstack? From their whitepaper, DAOstack defines themselves as “an operating system for DAOs”. From their website, “DAOstack is an open source project advancing the technology and adoption of decentralized governance.“ Both these definitions don’t mean much to beginner so to explain it another way, DAOstack is a “stack” or a group of technologies that has been invented using smart contracts and blockchains to allow the easy creation of DAOs or Distributed Autonomous Organisations. A more detailed article here goes into much more depth for those inclined. What is Alchemy? Alchemy is a nice user friendly interface for creating DAOs coz let’s face it, this technology is complicated enough without having to do everything in a command line terminal! On https://daostack.io/ you can “Explore DAO’s in Alchemy” which takes you to https://alchemy.daostack.io/ What is xDAI chain? “xDai Chain is a stable payments blockchain designed for fast and inexpensive stable transactions.” ie it is another blockchain network and […]

The way training should be … free

I got this email in my inbox recently about free training material from Corda, which is an “open source blockchain platform for business“. I decided to take a look and the content at https://training.corda.net/ is very well designed and presented. It is definitely a lot more user friendly than the documentation! It provides key concepts at the start and interestingly enough put blockchain fundamentals at the very end. I would have had it at the top as well but assume that because it wasn’t Corda specific, it is like an Appendix of sorts. There is an introduction to your first code or “CorDapp” which is very important, and then introduction to libraries and SDK’s because there is usually no need to write things from scratch nowadays. It jumps into Corda specific details and then rounds off with a nice summary. The content is very high quality and neatly packaged as well. The only thing I would add is a Hello World type application for the absolute newbie (which also serves as a system check), and a stronger “Where to next” section. The Corda blog is also very informative and consistent so hats off to them. This is all self paced learning […]

Crypto wallets live webinar

One of the first steps when embarking on your blockchain journey is to understand about wallets because when you get your bitcoins, ether or any other token for that matter, where are you going to store them? It can be a bit confusing when you first come across terms such as hot wallets, cold wallets, HD wallets, paper wallets, or hardware wallets. I’ll be hosting a webinar this Thursday at 6am AEST running through all you need to know about wallets and more. Yes, there are thousands of YouTube videos on this topic but I’ll be speaking from my own personal experience on these matters and not what I read in some book or web article. As a bonus, we’ll also have a special guest from MetaMask, Ethereum’s most popular wallet as well. You’ll also have the chance to ask some questions as well! (It is a live webinar after all!). The intended audience are those curious about the blockchain space but have yet to venture into it, or beginners who may have some experience but want to learn some more. The webinar agenda is roughly 20 minutes about wallets, 20 minutes from our MetaMask guest and then 15 minutes […]

During Singapore Fintech week, I had the opportunity to talk about what has happened in the last 11 years (it’s close enough to a decade!) of blockchains and where things are going. There was more than two people there I promise! 🙂 We all know that nobody likes to sit at the front! After the talk, I then provided a live demo on how to create a Singaporean Token with a very simple smart contract created and compiled in Remix and then deployed to Testnet. Then using MetaMask to see the tokens and transfer it to a member of the audience. It was also great to catch up with Vinay Mohan who runs the Singapore office and look forward to working more closely with the Singaporean team.

The Singapore Fintech Festival this year was enormous. It covered six halls, more than double of what it was last year and there were some big budget stalls from some very large companies. Not to be outdone, blockchain and crypto companies had a presence also. ConsenSys was located at several places. We had a dedicated spot set up in hall 3 along with presences at the OpenNodes booth and at the Ubin booth also. Joe Lubin was also present being interviewed on the tokenisation of everything in a fire side chat. Apparently there were over 60,000 participants over the week long event. I’m not sure how accurate those numbers are but there certainly was a lot of people! It was great to catch up with the rest of the team and also to keep at the forefront of this technology and other dominant players in the market.

CeBIT Australia and Blockchain

CEBIT Australia is a showcase of the dynamic merger of business with technology, where it’s going and how it can help you in your daily job. I went along to see the “blockchain”component of it which was relatively small but nevertheless good to see something blockchain related. There were three sessions on day 2 of CeBIT. A Blockchain 101 workshop, which wasn’t really a workshop but a 50 min talk of the blockchain landscape, and two panels. Tim actually did a very good job with his engaging talk. The audience kept growing and was easily the largest of the “mini” zones. The panel discussion was less engaging but having said that, panel discussions are hard in nature. Here, it was basically ask a question and get 4 opinions or thoughts. The audio quality was super clear though! Looking around at the event, it seemed quite empty to tell the truth. Even the main stage looked empty. Many of the topics looked interesting, especially around space and quantum computing and automation and AI. Maybe the other days were different but I didn’t end up returning as many of the booths and the technology on showcase lacked any wow factor.

Learning the basics of Stablecoins

There are plenty of articles, blogs and videos explaining what stablecoins are and how they work but they all define stablecoins in their own unique way and most confusing of all, categorise them differently with different terminology. Here, we’ll attempt to bring some clarity. What is the definition of a Stablecoin? There are lots of different ways to define stablecoins and it is often useful to appreciate these different definitions to help in your own understanding. Here are some examples: Stablecoins are cryptocurrencies designed to minimize the volatility of the price of the stablecoin, relative to some “stable” asset or basket of assets Wikipedia A price stable cryptocurrency whose market price is pegged to another stable asset Blockgeeks – https://www.youtube.com/watch?v=O3rVWLhBIPo A dollar denominated cryptocurrency Off Chain with Jimmy Song – https://medium.com/hackernoon/stablecoins-what-you-need-to-know-cb0bbf211864 A stablecoin is a type of cryptocurrency that is designed to maintain a stable market price. Binance Academy These are all valid definitions and what can be seen is that they are commonly referred to as a cryptocurrency and that they are relative, pegged, or fixed to a stable asset of some sort. Why use stablecoins? Currently, the most common use of stablecoins is as a safe haven for crypto traders. […]

Here are a list of some handy stablecoin comparison charts. Coincodex Coincodex is probably the best on as it provides the ability to select up to 17 stablecoins and compare their value over the time frame of your choice. Each stablecoin can be toggled on or off as well which is very useful. Longhash Longhash provides an interesting stablecoin health index as well as price charts for 5 stablecoins.

Platforms Based on Cryptoslate, 65% of all stable coins run on the Ethereum blockchain. It shouldn’t be surprising because it is far easier to launch a stablecoin on Ethereum than on other blockchains. How stable are stablecoins? According to The Stablecoin Index, most are pretty close to $1 “most” of the time. The screenshot below shows the deviation in the past week which, ignoring the upper and lower extremes, ranges from 1.008 to 0.9971. That is pretty good. Stablecoin Timeline Here is a brief timeline of the birth of various stablecoins. Tether – Launched in July 2014 as Realcoin before changing their name to Tether in Nov 2014.

“Brave Tango 5-8-3, special ops on board, repeat special ops on board” the police officer said on the walkie talkie as I sat at the back of a van with metal grills over all the windows. “What have I gotten myself into?” I said to myself as a million thoughts ran through my head, mostly all Hollywood movie scenarios, as I was driven to meet the Bank of South Pacific board of directors at their head office in Port Moresby. I was invited to share with the directors what blockchain technology was about in a 2 hour interactive presentation session. It was a privilege to be able to share what I had learnt in the last 4 years of eating, sleeping and breathing blockchain technologies but it must have been intense for them. Lots of new words and terminologies were introduced, acronyms used and demystified, and even technical concepts explained. I didn’t want to overwhelm the directors so only shared 1 technical concept and that was the idea of hashing. Instead of defining what it was with words, I actually showed them and encouraged them to boast their new found knowledge to their peers next time they go for drinks. […]

I was fortunate enough to have the opportunity to speak at a blockchain conference called Ethereal Summit in New York recently. It was a two day conference that focused on developments in the blockchain space and was also part of the run up to blockchain week where a three day conference run by Coindesk called “Consensus” and a one day Token Summit conference was held. I shared some of the work we’ve been doing at ConsenSys Academy with a talk called “Reinventing the way we learn blockchains”. Here is the presentation for those interested. I also had the chance to visit ConsenSys HQ in Brooklyn which is fast becoming a must see tourist spot for all those in the blockchain space. 10 points for guessing which graffiti covered door is the entrance into the office! If you can’t figure it out, use the next picture as a clue. I’m sitting outside on the front steps. In New York, I also got to meet the rest of the Academy team for the first time in 3D. ie “IRL” aka In Real Life. I must say that I’m very privileged to work with a bunch of very talented and dedicated people from […]
