How Lens helps us build user-centric Web3 products?

In our previous blog post, we covered one of the biggest challenges Web3 faces: building user (de)centric products. The main points were: One of the ways to solve this challenge is to start with the validation and exploration of the problems users have rather than a tech solution that can be developed. We want to […]

Deep Dive DeFi: Derivatives

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 […]

ML meets Blockchain: The Clash of Buzzwords

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 […]

Layer Hack: zkSync’s Account Abstraction

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, […]

Smart pointer: Rust vs C++

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 […]

User (de)centric design in Web3

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 […]

Blockchain Credentials with a Spice of ZK Magic

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 […]

Ticking All the Boxes: How Madara Modifications Enable On-Chain Game Logic

One of the main lessons from the previous two years is that the blockchain gaming space is expanding rapidly, with many new projects and features being built. However, it still remains in its infancy stage, as no title has managed to grab the mainstream market. I’m not talking about metaverse and virtual reality on the blockchain, though it is a massive part of the gaming space. I’m talking about a core gameplay experience that entirely runs on-chain.

One year in 3327 - Working in Web3 R&D 

So far, we only wrote about serious topics. Why not write something "light" this time? A couple of days ago, it was a year since I joined 3327 - a Web3 R&D and transitioned into Web3. This year has been one of the most exciting years in my career, so I am writing a short […]

Anonymity in MACI

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?). […]

Cosmos : Non-monolithic Blockchains

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 […]

The Dangers of ECDSA Signatures

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 […]

Can MACI really destroy the collusion?

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 […]

Rust: Under the Hood

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, […]

WTF is Token Engineering?

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 […]

WTF is 3327?

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.
