Solana solves this problem by using an innovative technology called Proof of History, which allows these “timestamps” to be built into the blockchain itself. This is done through a verifiable delay function, a VDF.
Solana’s implementation of Proof of History, alongside innovations like Tower BFT, Proof of Replication, and Gulf Stream combine to create the most performant blockchain in the world. Solana’s testnet is live today.
14 sie 2019 · The core innovation that underlays the Solana Network is Proof of History, and is exactly what the name suggests — a proof of historical events. Utilizing Proof of History creates a...
This paper proposes a new blockchain architecture based on Proof of History (PoH) - a proof for verifying order and passage of time between events. PoH is used to encode trustless passage of time into a ledger - an append only data structure.
26 sie 2024 · Proof of history allows the distributed system to agree on time without requiring communication and consensus beforehand. This is achieved by each validator on the network maintaining its own clock by encoding the passage of time in an SHA-256 sequential-hashing verifiable delay function (VDF).
28 lip 2022 · This article introduces Solana and the Proof of History (PoH) concept, including a discussion of how Proof of History improves transaction speeds and how it works with other...
1 kwi 2024 · Solana’s Proof of History (PoH) presents a promising alternative to traditional consensus mechanisms like Proof of Work on Bitcoin and Proof of Stake on Ethereum. While not without its challenges, PoH offers significant advantages in speed, scalability, and efficiency.
