Blockchain at its core is a peer-to-peer
distributed ledger that is
cryptographically secure, append-only,
immutable (extremely hard to change),
and updateable only via consensus or
agreement among peers.
Blockchain is a technology that helps to
exchange the values with various peer-

11. Types of Wallets
Hot Wallet
 Hot wallets are like normal wallet which we
carry for day to day transections But this
wallet are user friendly
 ONLINE therefore QUICK
 Cloud therefore FAST
 EASY access UNCOVERABLE when hacked
Cold wallet
 Cold wallet are similar to a vault, where
cryptocurrencies
 OFFLINE later disclosed online
 PK are Stored hardware or paper wallet
 SECURE from Unauthorised

16. WHAT
ARE
SMART
CONTR-
ACTS?

17. 1. A warranty claim
One of the solutions offered by Deloitte is the inclusion of a QR-code in a receipt.
2. Derivatives
Barclays and several other companies has already trialed a way of trading derivatives
using smart contracts
3. Insurance claims

18. 1. The Internet of Things (IoT)
The devices will use Ethereum smart contracts. For instance, we have the Ethereum lightbulb, we
have the Ethereum BlockCharge, involving the charging of electric vehicles, and lastly CryptoSeal;
this is a tamper-proof seal for drug safety.
2. Archiving and file storage
Decentralized cloud storage solutions available, such as Storj, Sia, Ethereum Swarm and so on.
3. The protection of intellectual property
An application called Ascribe, using Blockchain, already gives this protection.
4. Crime
5. Social media
Using Blockchain smart contracts, users of social media will be enabled to sell their personal data, if
they so desire. Such ideas are being investigated at MIT. The aim of the OPENPDS/SA project is to
provide the data-owner to tune the degree of privacy preservation using the Blockchain technology.
6. The use of smart contracts in elections and polls
Elections and polls could be greatly improved with smart contracts. There are various apps already
in existence, such as Blockchain Voting Machine, Follow My Vote and TIVI.
