Zk-SNARKs: updatable setups on the blockchain
Zk-SNARKs have proven to be a ‘Swiss army knife’ for blockchain and distributed ledgers, with applications in privacy, interoperability, and scalability
1 September 2022 12 mins read
Since their introduction, zero-knowledge proofs (ZKPs) have been used to support potential applications ranging from verifiable outsourced computation to anonymous credentials, within a multitude of settings that require a balance between privacy and integrity. ZKPs enable one party to prove to another that a certain statement or claim is true, without revealing the contents of…

Introducing Ofelimos: a proof-of-useful-work consensus protocol
IOG research introduces a new, provably secure, consensus protocol to minimize the energy wastage of proof-of-work blockchains
16 August 2022 11 mins read
The minimization of proof of work's (PoW) energy cost and carbon footprint is one of the most hotly discussed topics in the crypto space. Substituting the PoW primitive in Nakamoto's longest-chain protocol with a proof of useful work (PoUW) has long been theorized as an ideal solution in many respects but, to this day, the concept has lacked a convincingly secure realization.
Today, at the leading international cryptology conference, Crypto, Input Output Global, Inc (IOG) introduces Ofelimos, a novel PoUW-based blockchain protocol whose consensus mechanism simultaneously realizes a decentralized optimization-problem solver. The…
