Introduction to blockchains technology

blockchains technology is a tamper-proof communal digital ledger that annals transactions over a public or private network. As it is distributed to all network participants, the roster creates a permanent record in the form of blocks.

Each confirmed and validated block is linked and concatenated from the beginning of the chain to the last block, giving it the name of a blockchain.

Each computer on the network is referred to as a “node.”

How does a blockchains network work?

Instead of relying on a third party similar to a financial institution to broker transactions, participants in a blockchains technology network use an agreement protocol to agree on ledger contents, then cryptographic confusions and digital signatures to safeguard the integrity of transactions.

Consensus safeguards that the communal ledgers are identical, reducing the risk of fraudulent transactions since the manipulation would have to happen in many places simultaneously. Cryptographic hashes ensure that any change to the transaction input.

Even the most minor change, results in another hash value, indicating a potentially compromised transaction input. Digital signatures ensure transactions are from the senders (signed with private keys) and not scammers.

The peer-to-peer blockchain network prevents a single participant or a group of participants from controlling the underlying infrastructure or system. The participants in the network are all the same and adhere to the same protocols.

Essentially, the system records the chronological order of the transactions, and everyone accepts the validity of the transactions using the consensus model chosen. The result is dealings that are irreversible and agreed upon by all members in the network.

Public vs. private blockchains

Peer-to-Peer: Apiece “peer” has 100% of the data, then all updates are shared between the peers. This allows each pair to be more independent and operate even if connectivity to the rest of the network is lost.

Peer-to-peer is more robust as there is no central server to control, making it difficult to shut down the peer-to-peer network.

Client-Server: In a typical office environment, data is stored on servers, so you can access that data every time you log on. Servers store all data; an example is an internet, where websites are stored on servers.

What Are the Business Benefits of blockchains technology?

Blockchain can add value when:

  • Different parties share data and need the same visibility of that data
  • Multiple parties update data and require changes to be recorded
  • Participants must have confidence that the recorded changes have been verified as valid.
  • Intermediaries add cost and complexity
  • Interactions are time sensitive, and these delays add to costs
  • Transactions created by participants are interdependent

In traditional trading networks, all participants keep their ledgers with duplicates and discrepancies, leading to disputes, longer settlement times,

Also the need for intermediaries with the overheads that come with them.

However, using blockchain-based shared books, where transactions cannot be modified once validated.

companies can save time and costs while reducing risk. Blockchain technologies promise more transparency between willing participants, automation, personalization of the ledger, and more trust in the archive.

Blockchain consensus mechanisms provide a consistent data set with reduced errors and real-time benchmark data.

Because no participating member owns the source of information contained in the shared ledger, blockchain technologies introduce more trust and integrity in the flow of transaction information between participants.


In conclusion , Only time will tell how good the forecasts are for blockchain innovation as it competes alongside cloud and AI for outright victory.
