Summary On August the 25th an SSV validator got slashed, the Blox team got informed by one of the testnet operators (OneInfra). The slashing was caused by 2 double attestations the where broadcasted for the same slot with different block roots (double attestation). The slashing was primarily caused by not having slashing…

Secret Shared Validator (‘SSV’) is a unique technology that enables the distributed control and operation of an Ethereum validator. SSV uses an MPC threshold scheme with a consensus layer on top that governs the network. …

Secret Shared Validators (SSV) is a joint R&D project with the Ethereum Foundation (EF), the first secure and robust way to split Eth2 validator keys between non-trusting operators which can transform staking services, pool performance, and security. Staking on Ethereum is somewhat unique as every validator requires 32 ETH and…

In eth2 staking there are penalties for a non active validator, to encourage validators to perform their duty. A validator which is inactive for a significant amount of time will see his balance decrease until it reaches 16ETH, in which time that validator will get ejected from the the active…

Thank you Shay from the Prysm team for reviewing the code changes and enabling this to become a production feature. Problem statement The basic eth2 phase 0 slashing conditions premise dictates that a validator can’t forget past signed messages without a penalty. It’s a simple rule, don’t sign the same message but…

This is the second part of a two part post explaining in details BLS signatures and how they work. For part 1 click here Point at infinity A point at infinity is an important concept in elliptic curve math. Its basic definition is a point which is both infinitely high and low in…

Bitcoin and ethereum both use elliptic-curve cryptography for generating keys and signing transactions. The algorithm they both use is called Elliptic Curve Digital Signature Algorithm (ECDSA), which represents a secure way of signing a message (a transaction for example) using Elliptic Curve Cryptography (ECC). When work started on eth 2.0…

“1 CPU, 1 vote” was the philosophy on which Satoshi built bitcoin on. The idea was to distribute control over a financial system to the masses where everyone and no one would control it. …
