What It Is, How It Works and How to Make Money with It
Blockchain exchange is a technology through which information can be exchanged without the help of an intermediary. Its most famous application is cryptocurrency, but it also has other uses.
Blockchain exchange is a large database that records the exchange of information between users of the blockchain network. The registry is chained and encrypted. When an exchange takes place, various network users are responsible for verifying and authenticating it.
In this way, the corresponding blocks are registered in a chain of blocks distributed among the users of the network. Since the blockchain can only be updated by consensus, a shared database can be generated without central control.
If someone wants to make changes to the database, they won’t be able to make changes to its replicas, they have to make changes to all the replicas, which is pretty much impossible because the data is encrypted and it has an automatic synchronization mechanism.
Blockchain Exchange in the Economy: Cryptocurrencies
Although Bitcoin is the most famous cryptocurrency, it is not the only one. More than 1,500 can be found in the market today, although it is difficult to specify the exact number of recent currency fluctuations.
The function of each cryptocurrency is similar. They all use blockchain technology. The exchange of information they record is a financial transaction.
Due to the limited capacity of blockchain exchanges, when one of them does not accept any more transactions, it must be verified. This process is data mining. Miners are computers connected to a network that provide their processing power to validate blocks. This test involves a series of complex calculations that require time and effort.
Basically, this block is permanently registered in the chain and cannot be changed without changing all the other attached blocks. When miners receive a transaction, they perform two checks by querying the blockchain: they verify that the receiving account has not previously received the transaction, and they also verify that the account has not spent the amount sent.
To do this, the transaction must be associated with a private key. When a miner manages to validate a block, they are rewarded with cryptocurrency in return. Cryptocurrencies are increasingly being used in the real economy. Currently, you can buy various products and services with Bitcoin, there is a payment card that focuses on payments with cryptocurrencies, there is a platform to buy with cryptocurrencies on Amazon, mobile payment gateways, and there are more and more institutions that begging to accept payments in cryptocurrencies.
Types of Blockchain Exchanges and Their Characteristics
Blockchain exchange technology has undergone great development since its inception, and this development has attracted the attention of many players around the world. In the early days of this technology, the main stakeholders were people who could see the change and revolution it would bring.
It took a while for companies and governments to take an interest in the technology and use it in their projects. But the interests of companies and governments differ from those of an open society. This vision has led to the birth of a blockchain project unlike anything else we know before. This is how private blockchains and hybrid or federated blockchains arise.
Public Blockchain
This is the first type of blockchain exchange that is publicly available on the Internet. An example of this type of blockchain is Bitcoin, Ethereum, Dash, Monero, or Zcash. This type of blockchain exchange makes its data, software, and its development publicly available for anyone to review, revise, develop, or improve.
To achieve this, public blockchains have security measures in place to ensure that no malicious actor can easily change how they work. This is where Byzantine programming fault tolerance, robust consensus protocols, and DDoS protection come into play.
Ultimately, everything that helps improve cybersecurity is implemented on the web. The purpose of all of this is to keep the network up and running, and decentralized. Public blockchains allow anyone to participate. Whether a node user, miner, or administrator, people can access and be on the network without restrictions.
The economic maintenance of a blockchain depends on the systems integrated into it. In general, this economic system is based on mining and commissions for each transaction in the network.
Private or Permissioned Blockchains
As blockchain exchange technology developed and expanded, many companies became interested in it. This has led to the development of private or permissioned blockchain solutions. Also, this type of blockchain generally has the same elements as public blockchains, but unlike them, permissioned blockchains rely on a central entity that controls all operations on them.
This central unit provides access to users as well as controlling their roles and permissions on the blockchain. These are usually proprietary software development options, although free software development is also available.
Hyperledger is one of the most important private blockchain developments in the world of cryptocurrencies. The project, started by the Linux Foundation and several technology companies, is the largest example of a private blockchain.
We could also mention the case of R3 Corda or JP Morgan Quorum. Network access is limited to items that can only be approved by the central control unit.
Access to the transaction book or any other type of information generated by the block chain is private.
The financial maintenance of the blockchain is usually carried out by the companies that support the project. Private blockchains generally do not store cryptocurrency or perform mining operations.
Hybrid or Combined Blockchains
This type of blockchain exchange is a fusion of public and private. It is an attempt to get the best of both worlds.
In these blockchains, the membership of the network is private. This means that access to network resources is controlled by one or more entities. However, the ledger is public. This means that anyone can examine block by block everything that happens on the blockchain.
For example, these types of blockchain networks are useful for public or commercial organizations that want to securely store or share data. A great use case is in healthcare, where blockchain is beginning to be used to store data on drug production lines.
The stored data can be reviewed by the competent authorities to verify the quality at the level of the same company and government. The purpose of using this blockchain model is to maintain a high level of transparency and trust. Network access is limited to items that can only be approved by other control units.
Access to the transaction book or any other information generated by the blockchain is public.
No mining or cryptocurrencies. Network consensus is applied in other ways to ensure data accuracy.
It is semi-decentralized, which increases security and transparency.
