Useful Digital Identities are Neither Decentralized nor Centralized - they are Localized

Founder Check-in #1

It's been 15 days since I left my last company to venture out on my own. Many lovely folks have been checking in with me so I thought to gather my thoughts here.

I'm 29, burned out, and leaving my job - Here's my story

"Hey, I think I might be depressed"

Privacy for Public Registries - Proof Of Humanity x VeilOS

The community has been discussing various strategies around the privacy problem but it's non-trivial. The problem is not simply set membership - which ring signature could solve - but also maintaining Sybil-proof.

Useful Digital Identities are Neither Decentralized nor Centralized - they are Localized

Self-Sovereign Identity (SSI) platforms are emerging from the decentralization movement citing how they will replace the traditional Public Key Infrastructure (PKI) model where Certificate Authorities (CAs) are in charge of controlling the identities, but that will not be the case unless our society becomes more egalitarian. Until then, a hybrid of centralized and decentralized identity systems that are localized shall prevail.

My Personal Finance Stack — As a Millennial Living in Singapore

In this post, I share the list of tools, products, and services that I’ve been using for myself and the rationale behind using them. It covers everything from a savings account, credit card, brokerage, cryptocurrency exchange, mortgage, and even utility account.

Securing your smart contracts with symbolic executions - Part 1

When writing code, it is not only important that the code does what it is supposed to do, but also incapable of not doing anything that it’s not supposed to do. For smart contracts which live on forever on the blockchain, this cannot be more true. Those who fail to understand this get rekted.

Don't sweat the small things on your path to Financial Independence

Why should you care about privacy - even if you had nothing to hide

You feel a sense of disgust when your mum or spouse looking into your phone, but why is it that it's alright for internet companies or your country to do the same?

VeilOS - Preview of Privacy Preserving Application Engine

Following the discussion on how Zero-knowledge Proof (ZKP) can be used in the field of civic technologies (CivicTech) and specifically how it can be used by different NGOs to coordinate food distribution to the food insecured, I’ve embarked on creating a demo application to showcase how it can be done as part of my fellowship with RadicalXChange Foundation.

How to build a program that cannot do the wrong thing (illustrated with Typescript)

With any task, how to make things work concerned me the most. Learning to do test driven development (TDD) comes a long way to help me make sure the code works as I intended - for both positive and negative examples. However, as I come across the "Representable/Valid Principle" introduced in James Koppel's Advanced Software Design Web Course, I found out that I can write code that that not just does the right thing but also can't do the wrong thing.
