Each transaction goes through the authorization and authentication process before it becomes part of the blockchain. In fact, a transaction follows a step-by-step process until it is added to the blockchain. The flawless authentication and authorization of blockchain technology are ideal for different use cases and different industries.
You can use the same perfected authentication and authentication mechanism of blockchain to validate votes and review the results on an individual basis without tampering. For instance, users who use a crypto wallet can send and receive funds through the crypto network.
In a typical example, the crypto wallet is public but the private key that powers that wallet uses TLS (transport layer security). Ultimately, it’s the network that validates transactions and includes transactions into the blockchain.
It is crucial to realize and recognize that participants can use blockchain as a primary authentication provider. For instance, banks, airports, and government services can use a single identity protocol through blockchain technology. The single key pair makes the identity of registered users secure on the blockchain.
The blockchain is designed to work without any central authority that might interfere with the transaction. But it doesn’t change the fact that individuals still have to authenticate their transactions. In the blockchain, authentication works through cryptographic keys or data strings that identify users and allows access to their wallet or account on the network system.
Every user gets a public key and private key that are visible to other participants. But when a specific user combines a private key and a public key – it creates a secure and dedicated digital identity. The unique digital identity authenticates each user through digital signatures and makes it possible for the user to perform the transaction.
Once the transaction gets validation and approval from users, it then finally becomes part of the blockchain. In a public blockchain, users partake in consensus to decide whether or not to include a transaction in the chain. The majority of participants or nods have to concur to validate a transaction.
Steps: When a Transaction Becomes a Part of the Blockchain
Step #1 — the request of a transaction is processed and then moves to the authentication process
Step #2 — create a block that represents the transaction
Step #3 — the block goes to each participant or node in the network
Step #4 — all participants authenticate the transaction
Step #5 — nodes or participants get a reward in cryptocurrency for Proof of Work
Step #6 — the block becomes part of the existing blockchain
Step #7 — the roll out of the update takes place throughout the network
Step #8 — the transaction is finally complete
Proof of Stake and Mining
Today, blockchain networks follow the “Proof of Stake” protocol for validation. It allows participants to get a stake and own a specific portion of the cryptocurrency trading. It gives the nodes an opportunity to choose, confirm, and then validate transactions. It saves resources and computing power because there is no mining involved.
On the other hand, miners play an integral role when it comes to economies of scale. Miners essentially combine their resources through businesses that want to aggregate a lot of miners. Plus, miners can also share the fees and rewards in the blockchain network.
When it comes to decentralized authentication of blockchain technology, participants don’t have to worry about a central entity that would control different identities. Services can also use a single digital identity that highlights the strength and power of the blockchain. Even at its peak, blockchain technology is still evolving. But the technology has evolved to the point it can tackle current real-world problems and help individuals take the next big step in uniform and secure access control.
