transaction to verify the authenticity of the transaction, a private data

collection should be established in this case. In addition, because private

data is propagated through peer-to-peer rather than block, privacy data

collection is used when the transaction data must be confidential for the

sorting service peer.

Blockchain 3.0

A unique way of solving the scalability challenge is Blockchain 3 .0 DAG,

in which every node is depicted as a transaction in time and must attach to

prior transactions in order to be confirmed. The biggest challenge of

blockchains is addressed by DAGs by providing an efficient workaround to

scalability limitations. In the blink of an eye, transactions are approved.

There are currencies that use the next-generation DAG architecture.

Figure 2.5 depicts the Blockchain and DAG.

Figure 2.5 : Blockchain and DAG

Transactions that propagate uni-directionally consist of a mathematical

model on a base protocol. U sing the Poisson process, the flow of new

transactions can be modeled. The key mechanism of trust scores is used by
