Public/Permissioned Blockchain

Public/Permissioned Blockchain

You do not need an invitation to join the public blockchain. It is an open space where anyone can read and write data, but no one has the power to control anything.

Distributed, Immutable Database

The public blockchain is a decentralized platform accessible to anyone. In other words, there is no permit, which means anyone can join, write and read the information on the platform. A blockchain is a distributed platform where transaction data is compiled and stored in a blockchain format.

Therefore, the combination of these “blocks” forms a blockchain. The main feature that separates one block from another is the timestamp. Once its verified, the data which is stored on the platform cannot be altered despite being publicly available.

The public blockchain uses a consensus mechanism to verify transactions. The two leading public blockchains, Bitcoin and Ethereum, use the proof-of-work (PoW) consensus method. However, Ethereum has embarked on a journey of transition to a proof-of-stake (PoS) approach to consensus.

The social blockchain offers greater transparency compared to private networks and is as fragile as anyone can join and no single organization manages the entire system. Unfortunately, many public blockchains also suffer from low transaction rates and other metrics. In addition, the public blockchain is also limited in a few ways of compliance compared to the private blockchain.

The private and public blockchains are similar in the sense that each node in their network has an exact copy of their block, their database is unchanged and both forums rely on authentication agents.

Features of Public Blockchain

There are certain aspects of building a social blockchain. These features are different from other blockchain models. Let’s see what they are –

Every node can read and write in a book

• Anyone can download and add nodes to the system
• Technology is completely separated by nature
• It provides anonymity, which means no one can track what you do and bring it back to you
• It slows down compared to a private blockchain

What are the benefits of a blockchain?

Here are some of the benefits of a social blockchain network over a single common site website:

Fixed: It is very difficult to interrupt data in existing valid blocks unless the change is transparent to all involved and is therefore rejected. This means that participants can be confident that they can trust the recorded data in the blockchain, rather than relying on the central authority to manage the embedded data.

Decentralized and trustless: participants do not need to rely on trusted authorities to set up accounts. Instead, they rely on cryptographic keys, which they can generate themselves, to participate. Participants also do not have to rely on a central authority to maintain a ledger as anyone can configure a node and download the same ledger and create and send transactions and the blockchain protocol determines when transactions are recorded. The absence of a central authority reduces costs and increases efficiency.

Security: The cryptography of the public / private key (used to set up the account) is very secure.

Peer-to-peer: because the peer-to-peer network can continue to function even if other nodes in the network are not available. This makes the network much stronger than networks that rely on a central server where the network may be down if the server is not available.
