We cover the gaps between a working demo and a production system. Security fixes and the additional infrastructure, compliance, and tokenomics you need before even thinking about deploying this with real assets.

In Part 1, I showed you something most RWA demos conveniently avoid. We didn’t start with minting until we have an identity registry. We separated compliance from token logic. We made sure the transfers weren’t just balance checks, but decisions based on who is allowed to participate. At that point, your token stopped being a toy. But everything we’ve built so far is still perfectly self-contained. Smart contracts can't make HTTP requests. They can't check your brokerage account. They can't k...

RWAs are having a moment. So here's a 3-part tutorial on how to actually create them.

An ERC20 token is self-contained. Its value, behavior, and rules live entirely onchain. RWAs don’t work like that. RWAs are actual legal claims represented by a token. It’s something that even I am still finding difficult to grasp as a cryptonative. Because if it’s a legal claim, it means my system is no longer just smart contracts and math. It’s:smart contracts + regulation and documentsda governmentdata pipelinesand physical and legal constraints i can’t just require() awayWhich makes me wo...

People tend to overestimate how easy it is to create a blockchain. Just because you were able to deploy a network doesn’t make you an expert on blockchain. As a matter of fact, even an intern can do it in minutes. Here, try it. You know what else is easy to deploy? A webpage. Creating a blockchain is easy, and you can do it at zero cost and effort for as long as you don’t care about the design and spec of your network. Understanding the engineering constraints to design a secure and functiona...

Here I am, resurrecting my blog like a dusty necromancer coming back for one last summon. And what brought me back from the digital grave? Larpers. Everywhere. People posing as crypto 'experts' when they haven’t done the actual work of researching whatever the hekk it is they are talking about. It’s all vibes and appearances and no substance. Lately, the Orb and World has been made an antagonist in the Filipino crypto scene. And everyone suddenly became a data privacy expert and mor...

I haven’t escaped Cairo hell yet when the Cairo 1.0 rolled out, promising ZK-STARK-provable computation with simpler syntax and better security through an intermediate representation they call Sierra. Now after a few traumatic attempts at understanding the old version of Cairo (excuse me I’m quite normie), my fear was that the addition of this new steps will make it more complex, but luckily I was proven wrong.A Quick Rundown on How Cairo WorksCairo is specifically designed for creating valid...

If you’ve been here long enough, you would have already heard of the blockchain trilemma where you can only pick two out of three between security, speed, and decentralization. But that is so 2020. Some years ago, we expect one single blockchain to perform various functions for us. For instance, Ethereum has become congested because it was juggling between validating incoming transactions, arranging them into blocks, executing them, and finally keeping all these growing records available at a...

In da past two weeks, I have encountered at least 3 people who talk about quantum menace as if it will be the end of all existing blockchains today. So here are some facts:Most blockchains today rely on elliptic curve signatures (like ECDSA/EdDSA). These are not post-quantum secure. A sufficiently powerful quantum computer could forge signatures and spend funds from exposed keys. This is probably where they’re coming from.Hash functions like Keccak256 (used in Ethereum) are more resilient, ev...

Excuse any typo or grammar lapses in this post. Yer donkey just got poisoned by spoiled milk and is now drunk typing on a high fever. This helps tho. Today’s topic requires some courage to be published. We’d be talking about one of the most controversial protocols in DeFi and how ZK was used for its privacy-preserving properties: Tornado Cash. Do you know one of the founders of got jailed for it… fortunately he’s already released as of today-- just with a monitoring device on his ankles. Goms...

Lato-lato is the current craze where I live as of the time of this writing. And thank goodness coz while the ear-splitting clacks of this toy can be heard all over the town, it gave me an epiphany about a certain DeFi protocol that I’ve been dying to understand. The protocol iz Pendle Finance. Most crypto apers miss this because admittedly the barrier to understanding what it does is high. But I think it’s a hidden gold mine just waiting to be discovered by the wider crypto public. So… here w...

Depending on who you ask, the definition of Web3 wildly varies from “a new buzzword that crypto scammers use” to “the next big thing in the history of interwebz”. I’m here to tell you that both are true. And I’m not gonna pretend that Web3 is a utopian dream where only good projects emerge because that is simply not the reality of it. Web3 is a tool… it can be used for either good or bad and a lot of gray areas in between. But it is one powerful tool, so today I’m going to dissect what makes ...
