In a nutshell: Ian Grigg’s Ricardian contracts and digital assets prehistory

In a nutshell: Ian Grigg’s Ricardian contracts and digital assets prehistory

I enjoyed listening to Episode 151 of the podcast “Epicenter” (previously “Epicenter Bitcoin”) featuring Ian Grigg, inventor of Ricardian Contracts and blogger at Financial Cryptography. Here are my notes – part transcription, with some edits. This one is a goldmine and covers many topics: bonds, contracts, cash, Chaumian e-cash, DigiCash, financial cryptography, Ricardian contracts, digital signatures, smart contracts, dispute resolution, Ethereum, triple entry book-keeping, oh my!

Misunderstandings and paraphrasing errors are entirely mine.

In a nutshell: MultiChain (Epicenter Bitcoin interview – Nov 2015)

I enjoyed listening to episode 107 of the podcast “Epicenter Bitcoin” where Gideon Greenspan, CEO and Founder of Coin Sciences was interviewed about MultiChain. Gideon also writes a great blog.

Disruptive Innovation in FinTech

How should incumbents, startups, and VCs think about FinTech, disruption, and blockchains?

Over Chinese New Year I read about Professor Clayton Christensen’s fascinating model for identifying and dealing with disruptive innovation, and attempt to summarise it in this post.

Here we learn the differences and dynamics between disruptive innovation, sustaining innovation, and efficiency innovation. Each of them interact with the others, and the appropriate approaches and defence strategies differ. I then provide my own thoughts on how this framework relates to FinTech for incumbents, startups, and venture capitalists.

In a nutshell: DTCC whitepaper on distributed ledgers – Jan 2016

On 25 Jan 2016 the DTCC released a white paper entitled “Embracing Disruption – Tapping the potential of distributed ledgers to improve the post-trade landscape”.  It is a very good read: high quality, succinct, and cuts through the hype.
