9. EVOLUTION OF BLOCKCHAIN : TECHNOLOGY ROADMAP

10. BITCOIN
• Enables transaction directly with no need of trusted third party
• Enables the non-reversible transactions
• Decreases credit cost in minor casual transactions
• Decreases transaction fees
• Prevents double-spending

11. BITCOIN DATA STRUCTURE

12. ETHEREUM
➤ Ethereum is a public, open-source and block chain oriented
distributed computing protocol that features smart contracts
(scripting) functionality.
➤ The protocol has provided a decentralised virtual machine called
the Ethereum Virtual Machine (EVM), which carried out Turning-
complete scripts by using a global network of public nodes and
the token called ether, also referred to as gas.
➤ Gas is used for preventing the spam on networks and allocating
the resources in proportion to the incentive provided by the
request.
➤ Ethereum is also used as a protocol for decentralised applications,
smart contracts and decentralised autonomous organisations

18. HYPERLEDGER FABRIC
➤ Hyperledger is the open source blockchain platform, began in
2015 by the Linux Foundation, in an effort to support the
blockchain-based distributed ledgers.
➤ The protocol focuses ledgers developed to support
international business transactions, catering leading financial,
technological and supply chain businesses, with the objective
of improving a lot of performance and reliability aspects.

22. IPFS OVERVIEW
➤ IPFS is a peer-to-peer distributed file system that seeks to connect all
computing devices with the same system of files.
➤ In some ways, IPFS is similar to the World Wide Web, but IPFS could be seen
as a single BitTorrent swarm, exchanging objects within one Git repository.
➤ IPFS provides a high-throughput, content-addressed block storage model,
with content-addressed hyperlinks.This forms a generalised Merkle directed
acyclic graph (DAG).
➤ IPFS combines a distributed hash table, an incentivised block exchange, and
a self-certifying namespace.
➤ IPFS has no single point of failure, and nodes do not need to trust each other
not to tamper with data in transit.
➤ Distributed Content Delivery saves bandwidth and prevents DDoS attacks,
which HTTP struggles with.

30. RIPPLE CONSENSUS NETWORK
➤ The Ripple Transaction Protocol (RTXP), issued in 2012, has
been developed upon an open-source distributed consensus
ledger, Internet protocol, and native currency termed as XRP
(ripples).
➤ Ripple enables instant, safe and almost free global financial
transactions of any scale without any chargeback. The
protocol is embraced being able to support tokens presenting
cryptocurrency, fiat currency, commodity and any other value
unit like mobile minutes, frequent flier miles etc.

32. RIPPLE TECHNOLOGY INTEGRATION ARCHITECTURE

33. R3 CORDA
➤ Corda by the Company R3 is the distributed ledger protocol
that has been developed from the ground up for recording,
supervising and synchronising the financial agreements
among regulated financial institutions.
➤ It is, by great deal, stimulated by, and captures the advantages
of blockchain systems, with no design choices that turn
blockchains unsuitable for a lot of banking scenarios.
➤ Notary Nodes can run several consensus algorithms . Smart
Contracts cane written in Kotlin and are legally bounded
