Evaluating a Mina staking pool’s performance

Mina uses a proof of stake consensus mechanism with a block producer selection similar to Ouroboros, known as Ouroboros Samisika. The opportunity to produce a block for a slot is determined by a verifiable random function (VRF). This selection can be thought of like a lottery with each block producer…

An Introduction to MinaExplorer's BigQuery Public Dataset

Mina is a succinct blockchain, which means while we can verify the chain's current state using a zero-knowledge proof, the prior history is not retained. So, if we want to analyze the chain's history (for example, to see individual transactions), we need to obtain it from an archive node. The…

Running a Mina Archive Node

Mina is a succinct blockchain, and as a result, consensus nodes only store the recent history of the chain before discarding it (the last k blocks, currently 290). While prior transaction history is not required to prove the current state is valid (this is handled via a recursive zero-knowledge proof)…
