ZetaChain: A Revolutionary Blockchain with Smart Contracts for Cross-chain Transactions

ZetaChain is a cutting-edge blockchain technology that enables seamless cross-chain transactions through its native smart contracts. Its unique design includes a Proof-Stake blockchain system and a team of observers and signers who monitor and verify external blockchain events, transactions, and states. Using a single Threshold Signature Scheme key, the signers can securely send authenticated messages to external chains and hold assets like normal accounts. With ZetaChain, users can enjoy fast, secure, and efficient cross-chain transactions without the need for intermediaries.

Improving Transaction Scaling with Multithreaded Block Sharding

Blockchain-based cryptocurrencies often struggle to process high volumes of transactions due to limited network bandwidth. However, the Blockclique architecture solves this issue by sharding transactions across a block graph using a fixed number of threads. This allows for the creation of parallel, compatible blocks, each referencing one previous block of its respective thread. By improving scalability through this process, the blockchain ecosystem can accommodate thousands of transactions per second.

Improved zk-SNARKs for Randomized Algorithms with Universal Circuit Design

This paper presents a new and improved zk-SNARK system, designed specifically for randomized algorithms. Unlike previous systems, our approach does not encode randomness generation within the arithmetic circuit, resulting in faster prover times. Additionally, we propose a universal circuit that can verify consistency of any arithmetic circuit with a bounded number of operations by performing randomized checks. Our approach has numerous practical applications, and its potential significance in the field of cryptography cannot be overstated.

Analysis of Long-Range Attacks on Proof Stake Blockchains

While blockchain technology offers several benefits, it is not immune to attacks. In particular, proof of stake protocols are vulnerable to long-range attacks that can compromise the integrity of the blockchain. This article provides a comprehensive analysis of these attacks, which can allow an attacker to rewrite the history of transactions on the blockchain. We discuss the underlying principles of proof of stake protocols and the techniques used in these attacks. Additionally, we propose some countermeasures that can mitigate the risks of these attacks.
