While I was away… If you are one of my very few but precious readers, you would have noticed I was away for awhile as there is a gap in blog posts. What was I doing? Over the summer I was busy with blockchain events, meetups, online courses, in-person courses, exams, whitepapers, certifications and bad dreams. If you want to […]
First a Warning! Strong Personal Opinions Ahead! Recently I replied to couple of posts in Peerlyst, and someone asked if I wanted to write an actual blog entry. After some thinking, I decided it would not be easy for me to write blog posts for Peerlyst. I don’t think it is a suitable platform for personal/professional blog posts. If you don’t […]
Until recently I had thought of immutability as a Good Thing, in the context of blockchains. It is, after all, one of the most desirable attributes that prevents double spend and enables consensus. The security of the blockchain depends on it. As my learnings went from Bitcoin to Blockchains to Distributed Ledgers, I made a faulty extrapolation. I did not […]
I just attended a Toronto Crypto Sumit , which featured something called “myCryptoHippo” represented by a bright purple hippopotamus cartoon. I honestly did not know what to expect, but had a good surprise from that Hippopotamidae. Most of the event unfolded as expected, being a summit about cryptocurrencies. I promptly forgot most of it with the exception of the pink critter presentation. […]
Have you ever had an “Internet Afternoon”? I mean, one of those days where a 10 minute search turns into hours after falling into follow-the-link rabbit holes, assisted by Wikipedia. If you can relate to this xkcd webcomic then you know what I mean: Let me tell you the tale of my Internet Afternoon Time Vortex. Be advised that I […]
CIO Certified Blockchain Professional certification completed! When I got started on this “Blockchain journey” I was not looking for certifications. I know the usual arguments in favour and against certifications, from the “don’t mean anything” to “it shows commitment”. The truth of the matter is that I like going to classrooms, learning from live instructors and meeting like-minded people. I […]
Headlines: Hijacking Bitcoin: Routing Attacks on Cryptocurrencies for fun and profit, by evil ISPs! The bitcoin protocol does not seems to protect the network against routing attacks, which is created by concentration of hosts: 60 percent of Bitcoin traffic is visible to just three ISPs (as of mid-2017). As the bitcoin blockchain proof of work selects the sub-chains with the hardest […]
I recently attended a technology conference on Cybersecurity and Quantum Computing, hosted by University of Toronto, which left me wondering on what is about to happen to blockchain tech when quantum computing becomes a thing. I had some thoughts: Thought one: if anything can undo the blockchain immutability, quantum computing is the one thing to worry about. Bye Bye Immutability! […]
(for the ones afflicted with a lack of sense of humour, the following is satire) It all started with this video where Andreas Antonopoulos talked to the Canadian senate about bitcoin and blockchain regulation. After watching it I was left wondering who was that nice individual, that knew so much about bitcoin and was able to talk about it calmly and […]
As I see it the blockchain is a gift to mankind by an unknown person (or persons) going by the name of Satoshi Nakamoto. Nobody owns the cleverest idea since sliced bread, but software patents could be the wrench-in-the-works. That state of affairs wont last long. Here is a sample of opinions on what’s to come, some good some really bad. Here […]
