Blockchain can record and encrypt various types of transactions, including exchanges, such as transfer of funds and transfer of ownership of property. Below are some features of blockchain currency.
A distributed ledger that maintains its transaction list
The list of transactions is replicated to many computers in near real-time, rather than being stored on one central server.
Transaction records are maintained in P2P peer-to-peer networks
The ledger is only accessible from the network of partners who work together to update and maintain it.
There are no intermediaries in P2P networks
There are no central control or control body and no third party arbitrators (lawyers, banks, etc.) involved. In a private or consortium blockchain network, there is an organization that manages it.
Identity is verified by encryption and digital signature
Cryptography and digital signatures verify the status of the participants. They are also used to authenticate transactions.
Blockchains are roughly classified into public type (public chain), and private type (private chain), and each has different characteristics.
Public type of public chain
As the name implies, public networks are open to everyone, where millions of people are always available to join. These public ledgers do not require identity information, and most users trade using pseu-donyms.
Bitcoin is considered as the first public blockchain network and is still one of the largest. Also, there are platforms such as Ethereum that can perform transactions, including smart contracts.
Private type of private chain
A blockchain managed by a centralized organization is called a private nature. Existing users invite non-users for transactions and interactions. In these networks, the transactions on the ledger are generally invisible, and the existence of the network itself may be hidden. For Bitcoin trading visit bitcoin South African system.
Permission less type/Permission type
The types of blockchain can be roughly classified into the public kind and private type, and can also be classified into the permission less type and permission type.
Permission less type refers to a blockchain like the public type that does not require permission to join the network.
On the other hand, a blockchain like a private type that requires permission to participate in the network is called a permission type.
Verification by consensus
All changes on the ledger, whether public or private, are made by consensus. In other words, the record change on the ledger cannot be done unless the majority on the network agrees.
Example of using blockchain
A large medical institution is currently relying on electronic medical records to provide hospitals and doctors with information on the health of new and existing patients.
However, such records are often incomplete or missing information. By using a blockchain, doctors, hospitals, insurance companies, patients, etc. can uniformly view as well as bring up to date all medical records with an integrated ledger.
Virtual currency blockchain helps healthcare professionals to view and update their medical records and give patients a comprehensive view of their entire medical record. This allows patients to move from hospital to hospital in a more reliable, fast and straightforward process.
Next, let’s see how blockchain technology benefits the supply chain. Blockchain-based companies rely on a platform that allows all stakeholders to access and manage data that was previously stored separately and collaborate with their trading partners to create a trusted network. You can build in such a network, and it is possible to browse all transactions and also has the traceability function of products and products.
This approach helps companies monitor costs, labour efficiency, and even waste and emissions at every point in the supply chain. This makes excellent sense for companies looking to improve the efficiency, traceability and safety of complex supply chains. With continuous and near real-time access to ongoing journey information, companies can flexibly change shipping routes and better allocate production facilities, equipment and infrastructure to optimize supply chain capacity.

Bitcoin has an upper limit on circulation
Current currencies such as dollars and yen can be issued indefinitely as long as the central bank prints them, and the value of banknotes can be adjusted intentionally. And money holders, especially citizens who have alternatives, come at a cost. However, the issuance of Bitcoin is strictly limited by electronic computing.
