DAG - What is It ?

• DAG known as Directed Acyclic Graph is a data
  structure that uses topological ordering.DAG is
  an implementation of directed graphical
  structure.DAG is mostly used for solving problems
  such as data processing, finding the best route
  for navigation, scheduling, and data compression.
• DAG graph only involves transactions thus
  avoiding the need for the mining process. Thus
  DAG is known as Blockless data ledger that only
  contains transactions and eliminates the need of
  miners for mining a new block.

Blockchain Vs DAG

• Blockchain uses consensus algorithms like Proof
  of Work (PoW) and Proof of Stake (PoS) which
  relies on mining a new block on every transaction
  and follows some strategies to choose the miners
  for the blocks. This makes an insufficient
  situation for transactions.
• DAG is a concept that arose with the help of the
  concept called "Sidechains" which eliminated the
  mining process. Thus increasing the scalability
  of transactions.

Concepts of DAG

5
Elimination of Mining

• Bitcoin blockchain involves the process of mining
  and miners to validate a transaction. DAG network
  eliminates the mining process and the
  transactions go directly into the validations
  themselves.
• Thus DAG supports for automated validations and
  no miners, results in safer, secure faster and
  instant transactions.

6
Shorten the Width of Network

• In the blockchain, while validating a transaction
  it links to the previous transaction which might
  result in widening the network. In DAG, after
  validation, every transaction are linked to a new
  and also an existing transaction on the network.
• Therefore, DAG prefers an existing later
  transaction to link to a new transaction. The
  goal of DAG is to keep the network width under a
  certain range that can support quick transaction
  and its validation.

7
Swift Transactions

• As DAG has blockless nature, the transactions run
  directly into the networks which make for quicker
  transactions. The whole process of transactions
  on the DAG network is much faster than those of
  blockchains that are based on PoW and PoS.

8
Double-Spending Issues

• Bitcoin Blockchain uses unspent Transaction
  Output Model, which makes users to have only one
  transaction.
• In DAG, the validation of every transaction
  depends on the number of transactions supporting
  it. The rate of transactions entering the network
  is lower, which makes transactions safer and
  faster.
