I still have to pinch myself at times because never in a million years did I think I’d ever be where I am now. No I haven’t “made it” and no, not all my dreams have come true. What has changed though is my belief that anything really is possible no matter how hard or impossible it may seem and all this started with a simple technology called blockchains. Let me explain. I was never a super successful student at school no matter how hard I tried. Looking back now I know what I was missing. It was guidance, mentorship, advice, help and of course the Internet! I did ok at university and was an average student, striving but never achieving. I then went out and did what everyone does, I got a job. As an electrical engineer, I designed the electricals for shopping centres (Bayfair), rugby stadiums (Waikato) and office fit outs. I then switched over and gave Java programming a go. I was average at programming and soon found myself travelling in Asia eventually living in Japan and China for a number years. It was in Japan when I discovered what a blog was and started learning about […]

It was months in the making so to see it all come together was very rewarding. The team at the Blockchain Association of New Zealand put together the framework for the much anticipated Blockchain training course leading to certification with the Crypto Currency Certification Consortium (C4). BANZ ran the pilot course in Wellington last week with 9 people registered. Unfortunately one student had to defer the course due to illness. The course was structured in a collaborative fashion where students seated around a table was preferred over the typically classroom type, two to a desk scenario. This provided a less formal environment encouraging everyone to feel comfortable and confident to contribute and everyone did. Some highlights: The students background consisted of people experienced with mining, hardware wallets, tax and cyber security among others. What happened was that these people shared their experience in the appropriate section of the course which contributed to the over all course value. Having something explained from different angle aided the learning process. After the students were given some practise questions under time pressure, they were then asked to split into two groups and formulate questions for the other group. Some of them got really creative!

The story couldn’t have been scripted any better. 3 strangers with very different skill sets coming together at the last minute and snapping 2nd place in the 2017 Australian Blockchain Hackathon at the Michael Crouch Innovation Centre at the University of New South Wales in the weekend of November 24. The build up really happened the week before when legendary Bokky ran these workshops which looking back was really a pre-hackathon hackathon. Newbies got up and shared potential ideas for a hackathon. I didn’t have any ideas to productise to speak off but shared my ongoing research www.theicotrain.com and also an project I worked on earlier in the year Uber’ing Electricity on the Blockchain. There was talk of taking the Uber’ing Electricity concept and upgrading it to work with the micro Raiden network but all my gear was back in NZ so I ended up helping the organising team sweep the floor, wipe tables and carry pizza boxes from the boot of a car to the table. Matt and Mark both found teams but come Saturday morning ended up splitting and forming their own team. Mark is a Javascript programmer and Matt has experience in blockchains. On Saturday afternoon, I […]

Putting NZ land titles on the blockchain

True story. My mum came to me about 2 months ago and asked “How can I prove that I own my own house?” At that moment, I actually didn’t know. It was a black box that my “lawyer” handles but having heard a lot about land titles and the blockchain I decided to investigate this further. I called up Land Information New Zealand (LINZ) and discovered they had this LINZ Data Service that could be used to find owners of property.  This gives you a proof of property but to get an official document you have to order what’s called a “Certificate of Title“. This cost $15 and it can be delivered via email or via post. This is not certified however. To have it certified, it must be received by post, then a letter requesting it to be certified included and sent back to LINZ. It costs a further $11. Doesn’t make sense right? To make a change to the title, a manual lodgement is required. It takes 8-10 working days and $176 and $88 for resubmission. (rejected or requisition) With all the attention around blockchains, I decided to order a title for my mum, and then put that […]

If you understand Hash Functions, you’ll understand Blockchains

Introduction Hash functions are a fundamental part of blockchain technologies. If you understand hash functions, it will make understanding other concepts such as tamper proofing,  digital fingerprints and provenance easier. What is a hash function? The hash concept is actually quite simple. It’s the amount of jargon used that confuses people. Simply stated, a hash function takes some input data and creates some output data.  To expand on this concept, a hash function takes an input of any length and creates an output of fixed length . Here is an example using a type of hash function called md5: It takes an input string and created a string of random letters and numbers “a0680c04c4eb53884be77b4e10677f2b”. This is referred to as the message digest. It is also known as the digital fingerprint. This is because there is no way this digest can represent any other string. If I try and modify this to “I owe my sister $2” the message digest will be completely different. What are the types of hash functions? There are lots of different types of hash functions. You can wrap your head around them here. The main ones involving the blockchain are SHA256 and RIPEMD. The number such as 128 or 256 generally […]
