How to use threshold signatures to generate random beacons?

Author: ALEXANDER SKIDANOV Translation & Proofreading: IAN LIU & A Jian Source: Ethereum enthusiasts Looking back at 2015, the DFinity project proposed a random beacon scheme that excited the entire community-using BLS threshold signatures to generate random output, while ensuring the output is unbiased and unpredictable. However, today, until 2020, it is still difficult to […]

Dry Goods | Revalidation Proof vs. Error Proof

Author: Avihu Levy & Uri Kolodny Translation & Proofreading: Anzai C1int & A Jian Source: Ethereum enthusiasts -Photo courtesy of Artur Tumasjan from Unsplash- Lead In recent months, more and more attention has been paid to Optimistic Rollup (OR), an expansion framework based on Fault Proof. We at StarkWare use Validity Proofs (VP) because it […]

Getting started with blockchain

Digital Signature: A digital signature is considered a digital simulation of a handwritten signature. The important features of handwritten signatures are: 1. Your own signature can only be made by yourself; 2. Your own signature can be verified by anyone else; 3. Your own signature only contacts a particular file and cannot be used to […]

Dry goods | Understanding BLS signature algorithm

Editor's Note: The BLS signature algorithm is an algorithm that implements signature aggregation and key aggregation (that is, it can aggregate multiple keys into one key and aggregate multiple signatures into one signature). In the future Casper implementation of Ethereum, there are many certifiers who need to sign the block. To ensure the security of […]
