Blockchain is a crucial tool for organizations and developers to track codebases. The development of applications on the Blockchain ensures a quicker experience for users. Its system produces immutable records and less paperwork. It enables developers to simultaneously make updates and alterations to a secure code. 

The positive impact of blockchain is mentioned below:

• Lower expenses: The nature of blockchain can help enterprises save money. It improves the efficiency of transaction processing. Additionally, it streamlines reporting and auditing procedures and lessens manual activities like data aggregation and amendment. Experts mentioned financial institutions' savings as proof of the efficacy of blockchain, adding that the technology's capacity to simplify clearing and settlement directly translates into process cost savings. More generally, blockchain reduces costs for organizations by doing the processing that it is capable of without the need for middlemen like suppliers and third-party providers.
• Increases efficiency and speed: Conventional paper-intensive procedures take a long time, are subject to human mistake, and frequently call for third-party mediation. Transactions can be finished more quickly and effectively by automating these operations with blockchain. The blockchain may hold documentation and transaction information together, doing away with the necessity for paper exchange. Clearing and settlement can happen considerably more quickly because there is no need to balance various ledgers.
• Trust: Blockchain creates trust between different entities where trust does not exist or has not been proven. As a result, these entities are willing to engage in business transactions involving transactions or data sharing that they may not have done or would have required an intermediary to do so. Enabling trust is one of the most cited benefits of blockchain. Its value is evident in the initial use cases of the blockchain, facilitating transactions between entities that do not have a direct relationship but still need to share data or make payments. Bitcoin and cryptocurrencies in general are good examples of how blockchain creates trust between participants who do not know each other.

Negative Impact of block chain are:

• Scalability Is An Issue: Blockchains are not as scalable as their counterpart centralized system. If you have used the Bitcoin network, you know that transactions complete based on network congestion. This issue is related to scalability issues with the blockchain network. Simply put, the more people or nodes participating in the network, the greater the potential for a slowdown!
  However, there has been a growing shift in the way blockchain technology works. With the right development of technology, scalability options are also integrated into the Bitcoin network. The solution is to transact off-chain and use only the blockchain to store and access information.
• Blockchains are Sometimes Inefficient: Currently, there are several blockchain technologies. If you choose the popular ones, including the blockchain technology used by Bitcoin, you will see many inefficiencies in the system. This is one of the major downsides of blockchain.
  First of all, when I tried to set up a bitcoin miner on my system, I quickly discovered that the ledger can easily exceed hundreds of GB. It is not efficient at storing data, which can cause storage problems for many nodes that want to be part of the network.
