Abstract：How to Create Cryptocurrency?
Existing money's architecture
The basic roles of Bitcoin
The Bitcoin network's participants
Bitcoin is the first successful example of a non trusted monetary system, meaning one that does not want the intervention of a central authority for example the Federal Reserve or the European Central Bank. You can explore the wide range of chances accessible to build inside that unique ecosystem or be inspired to create your own cryptocurrency by studying how Bitcoin's technological architecture does this - the functions and specialized responsibilities.
To begin, go through the initial necessities of every financial system, then contrast them with Bitcoin's unique architecture and the roles that humans play in addition to hardware (HW) and software (SW).
FYI - Bitcoin is written with a capital B as a peer-to-peer cashless financial system, allowing for the use of bitcoin (small 'b') as the system's currency.
The current Financial system's architecture
Fiat money refers to monetary systems in existence. Fiat is a Latin term that meaning “by decree,” and it refers to how currencies like the US Dollar, Euro, and Yen are produced and handled.
Since 1971, the value of global currencies has been controlled mainly by the governments that issue them.
They work on a trust-based model and are not backed by any treasure like gold, just as was the case earlier.
· More information on how fiat banking works can be found here.
Anyone who uses fiat money must have faith in a central authority to set the rules of the monetary system and ensure that they are followed. This can be divided down into the following categories:
1. A monetary framework and settlement system consists of rules, policies & infrastructure for issuing new money and reaching agreement on transaction settlement.
2. System hierarchy - Assigning various levels of privilege to various parties in order to implement the framework and settlement function - both internally and externally -
There is some form of governing body at the top of the system hierarchy (2) that defines the rules of the overall (rules and policy) and oversees/delegates the settlement system (1).
In the actual world, the government delegated this authority to a central bank, which was charged with enforcing the policy, issuing new money, and managing a settlement system, while other regulators make efforts to keep the system in control.
Different levels of access to the financial system are granted to banks, payment services, and individual money users - merchants and consumers - through a network structure.
The Byzantine General's Problem makes it difficult to design a digital financial system that can
operate continually without the involvement of a central mediator.
This is an allegory about a Byzantine General who must make a war choice despite the fact that he knows he can't rely on the authenticity of everyone who gives him information about the situation.
So, in terms of systems, this issue is deciding on a plan of action when data is partial or untrustworthy.
The problem in a monetary system is what is known as a 'Double Spend,' or the probability of spending a balance more than once.
The Double Spend problem erodes trust in a financial system, justifying the necessity for a central authority to have the last say - to be the general - while also creating a point of weakness due to their power.
In the case of fiat money, this weakness has resulted in governments abusing their influence over the money supply by generating more of it.
As a result, inflation occurs in the real world, diminishing the purchase power of your savings and income.
The monetary structure of Bitcoin
Satoshi Nakamoto, the man who invented Bitcoin, solved the Double Spend problem by inventing a monetary system based on pre-defined rules written in computer code rather than a government policy paper.
Those principles are implemented as software that runs across a dispersed network of computers without regard for hierarchy, authorization, or trust. The rules are not enforced by a central authority; instead, they are followed by members in the Bitcoin network due to economic incentives for releasing Bitcoin at a predictable and constant rate toward a maximum fixed quantity. This eliminates the potential of monetary misuse while also generating continual consensus on balances, so resolving the problem of duplicate spending.
The most important laws of Bitcoin's monetary system can be summarized as follows:
· Bitcoin has a predetermined supply plan that will lead to a maximum of 21 million coins.
· The rate at which bitcoins are created in order to reach that limit is mathematically defined, halving every four years.
· Every ten minutes (currently set at 6,25), new bitcoins are minted; the system self-regulates to assure this.
· Bitcoin cannot be created in any other way.
The Bitcoin Monetary System's Primary Functions
Bitcoin wants diverse users in its network to meet up the following in order to function as a monetary system without a central mediator:
Keeping an up-to-date historical ledger of transactions and unpaid balances
Validate new transactions to ensure they follow the rules (consensus mechanism)
In the correct data format, add those transactions to the historical ledger.
Create new bitcoins at a predetermined rate (currently 6.25BTC per new block).
Allow wallets to spend and receive transactions and sync to the ledger
Act as a service for external users/services to access transactional data
Route information over its peer-to-peer network
These methods were wrapped by Satoshi Nakamoto in the initial reference code he wrote in 2008. Since then, the software has been modified and made available as a reference client, the most popular of which is Bitcoin Core.
Bitcoin Core allows anyone with a basic computer to join a network of Nodes that perform Bitcoin's operations, as well as offering a gateway for people who want to develop services to increase the ecosystem and user acceptance.
Different members in the Bitcoin network are known as nodes.
The Bitcoin network has no hierarchy, although there are many sorts of Nodes that perform the needed functions (as described above) to varying degrees.
· Nodes in their entirety: Except for the creation of new bitcoins, all functionalities are available.
· Nodes that are light in weight: Wallet & Routing (1 & 5)
· Issuance/Ordering; Routing & Full Ledger: Miners (3,4 & 7)
· API Clients - Pre-built connections to Bitcoin Core
· 3rd Party Services: External services can be powered by connecting to Bitcoin Core via API Clients or directly to Full Nodes.
In the following essay, you'll learn how Nodes interact to make Bitcoin operate. You'll all start to see how you can actively engage in the Bitcoin ecosystem by performing one of those jobs.
as well as the software and infrastructure that stands behind it, to maintain and improve
The nuances of exactly how the protocol works are left out of our review of Bitcoin's architecture - and later publications. If hashing, elliptic-curve cryptography, or peer-to-peer networks are your thing, there are ways to actively contribute to the Bitcoin Protocol's upkeep and development.
