Derivatives DeFi has been an emerging market for the past three years in the Web3 world. Protocols have tried to bridge the gap and bring traditional financial instruments to the Web3world, offering users decentralization, full custody, and favorable conditions to make their own choices with minimum intermediation.  So far, we (Web3 users) have been successful […]

Blockchain technology and ZK proofs may be the last missing puzzle pieces for creating trustless and secure decentralized machine learning networks. This complex symphony of technologies opens the door for accessing knowledge from private databases, such as hospitals or government databases, without leaking information while still providing verifiable models and predictions.  Intro Machine learning has […]

About Layer Hack Encode Club hosted a great hackathon focused on Layer 2 scaling solutions - Layer Hack. The hackathon lasted for nearly a month (Oct. 17 - Nov. 13), and was sponsored by AltLayer, Boba Network, Metis, and zkSync - each sponsor had their track with its own topic.  Out of those four tracks, […]

In the previous blog post, we got the idea about the ownership concept and how the Rust compiler works. This blog post will acquaint us with smart pointers and basic concepts to write safe and clean programs. It will be shown through examples in parallel in C++ and Rust. Even if you are not familiar […]

All in all, it's just another “de” in the world Decentralization, democracy, DeFi, dex, degen…🙈 Web3 is hyping us all, and somehow, we keep adding the prefix “de” as a common Web3 good to all of it. As a product manager, user research came to my attention early in my career. When I joined Web3 […]

MACI - Minimal Anti-Collusion Infrastructure is a collection of smart contracts, ZK circuits, and ts packages that we can use to build programs on top. We have already dealt with this topic, we summarized what has been done in MACI so far (our previous research on MACI and blog Can MACI really destroy the collusion?). […]

Motivation behind Cosmos  You’re tired of high fees and latency and generally dislike the current form of the blockchain space. Nothing meets your requirements, and you think about creating something new and better - a new chain. Thus a powerful and dangerous idea is born. Yet, now you are plagued with questions of where to […]

Introduction If you have a public and private key, chances are you’re using ECDSA signatures for every transaction you execute. But do you know how to protect yourself from the vulnerabilities this mechanism has? In this blog post, we want to explain how the ECDSA mechanism works, its vulnerabilities, and what you should be wary […]

Suppose you have a bank account or a company. For some reason, the administration will not simply trust your word when you tell them your name is John Doe, living in the Himalayas, and all the money from your account suddenly went to charity. Those nagging people demand some proof, so you must show an […]

It is challenging for naive voting systems, particularly those integrated into smart contract platforms, to prevent collusion.  MACI (Minimal Anti-Collusion Infrastructure) is a collection of smart contracts, ZK circuits, and its packages that we can use to build programs on top.  The initial idea related to the MACI project came from Vitalik Buterin, the co-founder […]

For decades, the most chosen languages for low-level programming are C and C++; they offer great power but bring responsibility to the programmer. Writing code in C++ became hard, so new languages were born - Go and Rust. Both target low-level operations tasks, operating systems, and cryptographic services, but they were born to produce efficient, […]

Ok, we are not trying to reinvent the wheel; just showing you the tools for the ultimate wheel creation.  In Web3, we have tokenized decentralized systems that anyone can participate in. Like any other, these systems must have rules and limitations to function correctly and according to their purpose. That is why they have their […]

Are you lost in the Web3 sea? Can't find your way back to the use of relevant technology?  Don't worry! At 3327, we are a crew of blockchain sailors with a ship fully prepared for storms like these. And like every good ship, we have a Radar that can detect anything coming our way!  That's […]

If you heard of us, the chances that you think we come from the future and work in parallel on 3327+ different things are high and potentially right. To help you figure us out, we cleared things up in this blog post - wtf we think when we say 3327 team.
