This story starts from a tweet, as a lot of stories in Crypto(currencies). @cobie tweeted the hash of a message, like he has done numerous times in the past. This turns out to be: SHA256("Interpol Red Notice for CZ") 0xefedf7c4a51516ef909fb0a1c11e7443ee8cf85727d3ec14d0b7c3682e4a2bb6 This started a ripple effect on the crypto market, because Cobie is seen as trustworthy in the cryptospace, and because it meant that CZ, the CEO of Binance, was under much more trouble than what is already assumed....

I started a small but interesting journey of building a bot for some MEV arbitrages in Ethereum. Through my project under Teal Finance on a DeFi options price aggregator, Rainbow, I explore and interact with various DeFi protocols. This is how I stumble upon 0x78e111f6, this mysterious function signature that is present in a lot of intriguing MEV transactions. This is my story of trying to uncover part of that mystery....

There are some contradictions in the ethos of cryptocurrencies. Some parts are overly pessimistic, beating the drum of an impending doomsday event. We complain about the current financial and monetary system, how the access is not fair, nor transparent. How it seems inefficient or efficient for rent seeking from all those intermediaries. The rich get richer and the poor get poorer.(Percy Bysshe Shelley) We see the lack of privacy with surveillance crippling through internet to sell ads when it is not to control and censor you....

Initially this was suppose to be a series of short blog posts. An excuse to build a writing habit, hopefully daily since September 2022. But it didn’t go as planned since 2022 finished with craziness so I am restarting the process. We’ll see how it goes. Anyway, Trust the process, as popularized by NBA’s Philadelphia 76ers. Here are my posts: Are blockchains optimistic or pessimistic technologies Tales of a builder: reversing 0x78e111f6, the infamous solidity signature of an MEV bot ...

Derivatives is the next frontier for DeFi. Options particularly are lagging, especially when compared to the traditional market. The main venue today, Deribit, while growing fast the past years, is still far behind Futures volume. We can expect more ways to buy or sell volatility on the crypto market in centralized fashion. Decentralized Finance(DeFi) is also brewing with ideas and implementations like Opyn, Lyra, UMA (KPI options), Hegic. We want to emphasis on three trends that rejoin on our investment thesis:...

Mummy, Daddy, what is a blockchain? Listen, Kid! Once upon a time, in a faraway land call the Internet, villagers were oppressed. They could not transact without obliging to the will of the Intermediaries, an organization that, in exchange for their services, required fees and “losing some control.” Then comes a mysterious warrior (or group of warriors, no one really knows for sure) called Satoshi Nakamoto. He brought a magic book with properties unheard of:...

“Never go to sea with two chronometers; take one or three." The problem of consensus is fundamental in the distributed computing field and the previous quote summarizes its difficulty. Think about it for a second, why should you not take two? If you do not see why, let me ask this question: What if one breaks? John Harrison’s H1 marine timepiece source What if, for whatever reason, they are not synchronized anymore and show different times?...
