In May 2017, the Indian Centre for Internet and Society think tank published a report detailing the ways in which India’s national identity database (Aadhaar) is leaking potentially compromising personal information. The information relates to over 130 million Indian nationals. The leaks create a great opportunity for financial fraud, and cause irreversible harm to the privacy of the individuals concerned.
It is clear that the central identity repository model has deficiencies. This post describes a new paradigm for managing our digital identities: self-sovereign identity.
There is a lot of misleading commentary about smart contracts, leading to confusion about what they are and what they can do. Here are three of the most common myths that I have noticed. This builds on a previous piece, a gentle introduction to smart contracts.
Myth: Smart contracts are self-executing bits of code
A blockchain is a type of distributed ledger. But new distributed ledgers are emerging. These are databases where control over the data’s evolution is shared between entities. Here’s a handy cheatsheet.
I have noticed a great deal of confusion when people talk about “Hyperledger”. I recently gave a talk about this at a meetup hosted in Paypal’s offices in Singapore. This article summarises the talk.
Hyperledger is a project, not a technology, and you don’t build stuff on Hyperledger.
When people ask, “What is Hyperledger?”, the answer I give is usually “Do you mean the project called Hyperledger run by The Linux Foundation, or do you mean one of the ledger technologies incubated by that project which used to be confusingly called Hyperledger Fabric?”. The first is a group of people, the second other is a bunch of code.
