Slide 13

This slide showcases multiple advantages offered by blockchain technology in data storage systems such as tamper-proof data verifiability, cutting out the intermediaries, and protection against data breaches.

Instructor’s Notes:

The different benefits of blockchain in data storage systems are:

Tamper-Proof Data:

• Creating an effective and verifiable backup helps prove that data has not been tampered with
• Only hashes of data blocks are stored on the distributed cloud storage system
• Encrypted and distributed hashes can easily verify  data blocks

Verifiability:

• Blockchain also provides a sequential chain. Each block contains a cryptographic hash of the previous block
• It links blocks, thereby creating a decentralized transaction ledger

No More Middlemen:

• The major change that blockchains are likely to bring is disintermediation
• Distribution across a chain of computers also makes blockchain harder to attack
• It is a self-verified sequential storage scheme that can be used to immutably record transactions and ownership for negotiating and enforcing contracts

Instructor’s Notes:

The multiple disadvantages of blockchain based decentralized data storage are:

Lack of Trust:

• It works on Peer-to-Peer technology. Businesses and customers find it difficult to trust the decentralized network as it lacks accountability for lost data or misplaced transactions
• Developers, however, are working to create a high level of security within the decentralized network

Migration-Related Concerns:

• This technology is in its initial stages of development; this phase will continue for a few more years
• Performance issues keep businesses and consumers from immediately migrating to decentralized storage systems
• For early adopters, it is the right time to jump-in on this technology before it becomes as mainstream as the cloud

Slide 24

This slide showcases use cases of blockchain data management such as legal document management, accounting, intellectual property, government, and security.

Instructor’s Notes:

The use cases of blockchain data management are:

Legal Document Management:

• The use of blockchain to authenticate legal documents is a consequence of its immutable and tamper-resistant storage
• Currently, the data and veracity of legal documents are established with a mutual agreement or a third party. Typically, these are a notary, the 
   e- signature mechanism, or email
• These methods are not completely reliable but storing records on a public blockchain provides valid proof that documents do exist and are available, when needed

Accounting:

• Frauds in accounting will remain a problem in the system as human beings are involved in the preparation of accounts
• The use of blockchain technology, however, helps reduce fraud and improve the efficiency of the accounting process

Intellectual Property: 

• Digitization in modern art and intellectual property has increased the problem of duplicacy due to the possibility of creating duplicate artwork
• The ownership and apparent date of creation can be easily modified
• The system of Private Key Infrastructure (PKI) does allow the signing of digital creation, but it does not include a reliable timestamp. Thus, it becomes impossible to determine which of the signed digital assets were created first
• Combining PKI with blockchain technology, users, users can provide a complete digital intellectual property rights solution
• Placing the signed asset on a blockchain helps identify the actual digital asset

Governance:

• The government is the main arbiter of our legal and intellectual property systems, and it regulates most aspects of financial accounting
• By using blockchain for legal and intellectual property matters, the government is in a position to offer better governance; it can also offer additional, unique incentives to stakeholders
• As society becomes more digitize government will also need to move from paperwork to digital record keeping. Blockchain technology offers effective ways to maintain and secure records

Security:

• Blockchain has emerged as a key technology for defending our digital security key technology for defenders of digital security
• The immutability of blockchain records creates many opportunities in both preventing and limiting the chance of breach and reacting and responding, if and when it breaches occurs in any digital system
