All about nodes, their purpose and types

Hello, community! 👋🏻
In this post, we will tell you about nodes, their purpose, and types.

In PZM Cash, any active electronic device can be a node. The role of the node is to maintain the network in order to distribute and store copies of the blockchain and process transactions. Nodes are often located in the structure of trees known as binary trees.

🔗 Usually, a node has three purposes:
⚙️ Follow the rules (consensus online)
⚙️ Share information (about transactions and the amount of funds)
⚙️ Keep a copy of confirmed transactions

The PZM Cash nodes are synchronized, so if even a significant number of nodes fail, the remaining nodes will indicate an error. Therefore, to carry out an attack on a blockchain, an attacker needs to synchronously change data in a huge number of nodes, which becomes more and more difficult as the network grows. This also eliminates the possibility of a double-spending error, when the same coin can participate simultaneously in different transactions.

🔗 Types of Nodes

There are different types of nodes, but each of them has one feature — you will need equipment to host the node or to connect to other nodes. There are nodes for mining new coins, Web nodes, Archival, Truncated, Full, Light, etc. PZM Cash uses full nodes and light clients.

🔹 Full Nodes contain a complete copy of the blockchain history, including all created blocks. A full PZM Cash node can participate in the creation of new blocks — forging. The holder of a full node can actively participate in the formation of the blockchain by grouping incoming transactions into blocks and distributing them over the network.

🔹 Light Nodes or Simple Payment Verification (SPV) nodes — contain only the data that is important for the node, which saves resources. Therefore, they are ideal for organizing a dedicated cryptocurrency wallet. In PZM, such nodes allow you to generate transactions and track the balance of the wallet, the device will not be loaded with anything superfluous. This makes it possible to work on mobile devices or in your account on the PZM Cash Wallet website. At the same time, to send transactions, it is enough to store the private keys with which these transactions are signed.

However, unlike other cryptocurrencies, users of the PZM Cash light client can receive rewards for supporting the ecosystem. Yes, a light client cannot participate in forging and adding new blocks, but the PoS mining algorithm ensures a steady flow of new coins to the balance of light wallets.
