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…

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)…

While 2018 was largely dominated by the declining price of ZEC (and all major cryptocurrencies), it marked a significant milestone in the evolution of Zcash with both the Overwinter and Sapling network upgrades taking place. As a result, shielded transactions can now routinely be sent in a couple of seconds…
