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.

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 […]

Blockchain Credentials ZK

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 […]

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, […]

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 […]
