Introduction In the digital age, where data security and integrity are most important, cryptographic hash functions form the backbone of modern system, including blockchain technologies and zero-knowledge proof protocols. Poseidon hash, introduced in the research paper Poseidon: A New Hash Function for Zero-Knowledge Proof Systems, offers an innovative approach to hashing within finite fields. This […]

Have you heard of Stealth Addresses (SA)? Do you know what cryptography is used in their background? Have you heard of BaseSAP, Umbra, or Monero? If so, then find out here what the Curvy protocol is and how it differs from the above protocols. There is a great need to introduce private transactions on public […]

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.

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 […]

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 […]

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.
