Ethereum’s rollups are 'gold standard’ but Plasma needs a revisit: Buterin

Vitalik Buterin called the early Ethereum scaling solution Plasma “underrated” and a “significant security upgrade” for chains that would otherwise be validiums. Plasma, a once-prominent Ethereum layer 2 scaling solution, should be revisited by teams currently working on zero-knowledge Ethereum Virtual Machines (EVMs), says Ethereum co-founder Vitalik Buterin. Invented in 2017, Plasma diverts data and computation — except deposits, withdrawals and Merkle roots — to an off-chain environment. It was superseded by optimistic and zero-knowledge (ZK)- rollups as the two solutions offered cheaper client-side data storage costs and security properties that “cannot be matched,” Buterin explained in a Nov. 14 X (Twitter) post.

Bitcoin pioneer Hal Finney talks zk proofs in 25-year-old unearthed footage

A recently resurfaced video shows Hal Finney discussing the possibility of zero-knowledge proofs at an annual cryptology conference in California some 25 years ago. Early Bitcoin (BTC) pioneer Hal Finney shared his vision for zero-knowledge proofs more than 25 years ago, a full decade before the launch of the first cryptocurrency, Bitcoin.  The video, purportedly from the Crypto ‘98 conference held on Aug. 26, 1998, in Santa Barbara, shows Finney discussing in detail, the concept of zero-knowledge proof s — a cryptographic technology that gained immense popularity decades later. ️ NEW: Bitcoin legend Hal Finney discusses Zero-Knowledge Proofs in a newly unearthed presentation, made 25 years ago at Crypto '98 in Santa Barbara.
