In this tutorial-style episode, we’re going to go over the various steps that are required for setting up a ZenCash secure node. The discussion will be limited to a very high level, with the purpose of giving you a rough idea of the magnitude of the associated workload.
Summary
In a couple of sentences, ZenCash secure nodes enable reward entitlement for operators. Said nodes solve challenges, associated with computational validation of shielded transactions within the ZenCash blockchain. And this happens via a form of staking.
Minimum requirements
42 ZEN for staking.An extra 0.5-0.8 ZEN for transaction costs and secure node “gas”.Domain-name ownership.Static IP (either IPv4 or IPv6 will work).4 GB RAM.15 GB SSD hard-drive space.64-bit processor.A clean install of a 64-bit Linux-based OS on the secure node server.Challenge solution within the time limit of 5 minutes.Relevant entities
“Local” ZenCash wallet for staking.“Remote” server for secure node hosting.Dedicated domain name, as a point of access.External to your secure node, challenge allotting “overlord”.The set of all remaining secure nodes.Episode 3: Scams 101
