Blockchain galore

April 30, 2018 Leave a comment

MIT tech magazine has a whole issue dedicated to Blockchain (and crypto currencies). Worth a look both for the beginner (e.g. a glossary , the differences between the most prominent crypto currencies (see below)) and more advanced musings (e.g. why Bitcoin as a currency would be a disaster).

IBM has ~30% of Blockchain market

February 21, 2018 Leave a comment

Apparently IBM has ~30% of the enterprise Blockchain market (worth around $700M) according to a new study by Wintergreen. They also have about 1500 people dedicated to this group, are doing about 400 projects, have revenues that have growth ~10% YoY and have appointed the former head of services to lead this effort.

While’s there no doubt that IBM has captured the headlines and is aggressively pursuing this space, I wouldn’t put too much credence in the market share number; it’s way too early to call winners yet.

~95% of Bitcoin owned by ~5%?

January 19, 2018 Leave a comment

I want to be the last to add fuel to the crypto mania, but I found this chart in a report by Credit Suisse (Blockchain 2.0, Jan 11 2018) interesting. Apparently about 95% of the Bitcoin are owned by roughly 5% of BitCoin addresses, or so it seems. In fact the concentration may be under counting the actual # of wallets.

(The report, other than this is mostly forgettable).

Estonia: Epitome of digital government?

December 18, 2017 Leave a comment

Nice article in the New Yorker a few weeks ago on the backstory on how  Estonia (a tiny country of ~1M people)  has created probably the most digitally advanced government.

The normal services that government is involved with—legislation, voting, education, justice, health care, banking, taxes, policing, and so on—have been digitally linked across one platform, wiring up the nation

Apparently, no one has to enter any information twice (think hospital / doctor forms, loan forms etc.) and the whole effort saves them about 2% of GDP a year. (If you applied that to the US GDP of ~$20T, that would save about $400B/year). For the Blockchain enthusiasts, you’ll be glad to hear that the backbone of their digital security + data integrity is (of course) on a Blockchain (called KSI from Guardtime).

Parallels between TCP/IP and Blockchain

December 14, 2017 Leave a comment

I’m way late to this article, but I found this write up in HBR on the potential of Blockchain pretty compelling. Essentially, the authors do a nice job comparing what TCP/IP enabled (essentially lowering the cost of connections) to the potential that Blockchain has (essentially reducing the cost of transactions).

The parallels between blockchain and TCP/IP are clear. Just as e-mail enabled bilateral messaging, bitcoin enables bilateral financial transactions. The development and maintenance of blockchain is open, distributed, and shared—just like TCP/IP’s. A team of volunteers around the world maintains the core software. And just like e-mail, bitcoin first caught on with an enthusiastic but relatively small community.

TCP/IP unlocked new economic value by dramatically lowering the cost of connections. Similarly, blockchain could dramatically reduce the cost of transactions. It has the potential to become the system of record for all transactions. If that happens, the economy will once again undergo a radical shift, as new, blockchain-based sources of influence and control emerge.

Definitely worth a quick read.

Nice talk on blockchains vs. databases

I always find it refreshing when someone does a good job at cutting through the smoke and getting to the essence of the issue. Gideon Greenspan (CEO of Multichain), does a great job in doing just that in this video explaining the essential difference between a database and Blockchain. If you like this, you may also want to check out some of their posts on their blog.

Awesome book on Blockchain

ethereum henning book

I came across this awesome book on Blockchain (particularly Ethereum) by Henning Diedrich. For me this has the right balance. It doesn’t have any of the hype associated with the typical business book on this topic and doesn’t force the reader to understand the details of a particular algorithm. But it does do a great job of explaining simply what the fundamentals of Blockchain in a clear way. Highly recommended.

(Full disclosure: I’m about 1/2 way through this)
