How to get a Hive Account

A system of interconnected computer related devices. This forms a digital network that allows for the sharing of resources.

Digital networks play a critical role in modern society, enabling communication, collaboration, and the sharing of information and resources on a global scale. They are used in a wide range of applications, from personal communication and entertainment to business and industry.

Some of the devices on a network are:

  • servers
  • laptops
  • personal computers
  • mobile devices
  • printers
  • scanners

These operate using a common set of standards called protocols. This allows for communications between the different nodes on the network.

Most networks tend to be centralized meaning the data is controlled by one or two entities. For example, a corporation will have its own internal network allowing its personnel to access it.

Data is housed on multiple servers which are mirrors of each other. This ensures that if one node is corrupted, there are others with the same data.

One of the challenges is hackers. With a centralized network, access in one area opens up everything. Companies go to enormous lengths to try and protect their data.

On a network, nodes can be connected either by wires or wireless.

Types

A digital network is a collection of interconnected devices, such as computers, servers, and other electronic systems, that are linked together to facilitate communication and data transfer. Digital networks enable the sharing of information and resources, such as files, applications, and services, between devices and users.

There are several types of digital networks, including:

  1. Local Area Networks (LANs): A LAN is a network that connects devices in a limited geographical area, such as a home, office, or school.

  2. Wide Area Networks (WANs): A WAN is a network that covers a larger geographical area, such as a city, state, or country. The internet is the most well-known example of a WAN.

  3. Metropolitan Area Networks (MANs): A MAN is a network that covers a metropolitan area, such as a city or a large campus.

  4. Wireless Networks: A wireless network is a network that uses wireless communication technologies, such as Wi-Fi or cellular networks, to connect devices.

  5. Cloud Networks: A cloud network is a network that uses cloud computing technologies to provide remote access to computing resources, such as servers, storage, and applications.

Blockchain

A blockchain is a decentralized network of computer nodes.

On these networks, the base code is run on multiple computers, each running the same software. The data is mostly ledger information, recording cryptocurrency transactions. The ledgers resemble those of other financial institutions such as banks.

Unlike a centralized system where the different nodes are all under the control of one entity, node operators in a blockchain network are unrelated. The protocol is what enables the different nodes to arrive at consensus.

If one node does not match the rest, the transaction is rejected by the others. This makes the ledger immutable since the data cannot be changed. When it comes to monetary transactions, one of the largest breakthroughs of Bitcoin was the solving of the double spend problem.

That network used the Proof-of-Work protocol to arrive at consensus. Since that time, we saw the introduction of Proof-of-Stake as well as Delegated-Proof-of-Stake. Blockchains such as Hive also enable more than just financial transactions, moving to a fully decentralized text database.

Monetary Systems

Networks are a vital component to modern monetary systems. Since all information is kept in digital forms, specific entities are responsible for ledger management.

Under the central bank system, inter-bank transactions are recorded by the central bank. At the same time, commercial banks maintain ledgers of the currency that is flowing through the network. Each account is adjusted to maintain a proper balance as debits and credits occur.

There are a number of other financial institutions that are a part of the system. This includes brokerage firms, payment companies such as Visa, point of sale systems, automated teller machines (ATM), and investment banks. Each network is a ledger system, connected to other ones.

Throughout much of the 1900s, these were communication systems. With the computer age, these system were digitized becoming glorified computer networks.

This is the premise of ledger based money.
