The curse of immutability, and sour pickles

The curse of immutability, and sour pickles

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 like myCryptoHippo

I like myCryptoHippo

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. […]

First Blockchain Certification!

First Blockchain Certification!

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 […]

The Blockchain vs the ISP

The Blockchain vs the ISP

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 […]

Blockchain Quantum Threat

Blockchain Quantum Threat

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! […]

Youtube induced Bitcoinosis

Youtube induced Bitcoinosis

(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 […]

Blockchain and Patents

Blockchain and Patents

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 […]

What on a hash?!

What on a hash?!

I got this question from a friend (you know who you are) who has mined crypto goodies and just came to think about what those hashes are all about. So.. what is the deal with hashes? I am going to assume whoever is reading this has no idea what hashes are, which gives me freedom to explain it my way. […]
