Really You need to look these blockchain changes

These records can’t be changed as the model is distributed: there isn’t a central authority but there also isn’t any involved party (those doing transactions) that can change information. Blockchain relies on peer-to-peer network principles whereby each encrypted block in the chain is linked to the next.
Why the peer-to-peer network and absence of a central authority?
Because blockchain was precisely ‘invented’ to solve the challenge of the lack of a central authority in cryptocurrency Bitcoin. The attention for blockchain from a security and secure transaction perspective is, among others, related to the fact that blockchain is a cryptographic ledger whereby the chain consists of encrypted blocks and after the validation of the transaction (peer-to-peer and across the network)it is added as a block to the chain as a permanent and unchangeable record of transaction in digital ecosystems with heavy transaction processing whereby transactions, data and speed increase and meet the need fo…

Tokenization story you need Vault based Vs Vault-less

The term tokenization refers to create a numeric or alphanumeric number in place of original card number. So that the chances hacking credit card numbers are minimised.

Let us see a quick example, where card number will be tokenized in the analysis of big data:

There are two kind of servers currently popular for implementing tokenization.

Vault based Vault-lessVault based server - The term vault based means both card number and token will be stored in a Table usually Teradata tables. During increasing volume of transactions, the handling of Table is a big challenge.
Every time during tokenization it stores a record for each card and its token. When you used a card multiple times, each time it generates multiple tokens. It is a fundamental concept.
So the challenge here is Table size will be increased.
Vault-less server- The recent established technology is much faster than vault based model, here the card numbers and tokens will not be stored. Whenever it received a request, it generate…

What is a platform?

Without this development of software is not possible...

Why development not possible?

The development need to create a project and deploy into production. So that the real use can feel by users at their end.

Ok...

Let us come to three popular platforms that are highly used in Blockchain applications:

HyperLedgerIBM BlueMixMicrosoft AzureHyperLeder- The Hyperledger project is led by Executive Director Brian Behlendorf, who has decades of experience dating back to the original Linux Foundation and Apache Foundation, as well as being a CTO of the World Economic Forum.

Blockchain awesome story backbone to bitcoin

Bitcoin demonstrates the purest aspects of blockchain technology. It's the baseline that all other blockchains are compared to and the framework that nearly all have drawn upon. Knowing the basics of how the Bitcoin blockchain operates will allow you to better understand all the other technology you encounter in this ecosystem.

The process how messages stored
The Bitcoin blockchain is one of the largest and most powerful blockchains in the world. It was designed primarily to send Bitcoin, the cryptocurrency. So, naturally, in order to create a message in the Bitcoin blockchain, you must send some Bitcoins from one account to another.

When you send Bitcoins from one account to another, a transaction history is recorded in the Bitcoin blockchain. After a transaction has been entered, the information can't be removed — your message will be around as long as Bitcoin is in existence.
This concept of permanence is powerful — it's the most important characteristic of any blockcha…

Blockchain four possible disadvantages you need

There are some possible disadvantages. But, these are just a list sof ar. You already came to know about complete information on Blockchain in my previous post. Here the details are as follows. The disadvantages are as follows: Lack of privacyLoss of personal responsibilityLoss of jobsReintermediationAlso the critical blockchain technologies explained here.
Lack of Privacy


Public blockchains do not hide any of their data. Instead, everyone is able to read the whole history of transactions. This level of transparency is frightening for those who want to protect their privacy. These concerns are understandable when taking into account the level at which personal data are already collected and utilized by large corporations or intelligence agencies.

Loss of Responsibility

Loss of personal responsibility is often considered a consequence of disintermediation. Intermediaries not only bring different parties of a contract together but may also provide guarantees. They offer reconciliation in…
