4. A blockchain is a distributed software
network that functions both as a
digital ledger and a mechanism
enabling the secure transfer of assets
without an intermediary.

5. BLOCKS
Every chain consists of multiple blocks.
MINERS
Miners create new block on the chain through a process called mining
NODES
Nodes can be any kind of electronic device that maintains copies of the blockchain and keeps the network
functioning.

10. INTRODUCTION
Blockchain technologies provide ledger databases whose records are immutable and cryptographically signed using
a distributed consensus or validation protocol
Blockchain technologies are built around platforms, infrastructure, APIs and management tools.
DISTRIBUTED COMPUTING
Method of computer processing in which different parts of a program are run simultaneously by two or more
computers that are communicated with each other over a network

15. What did we understand from
our research papers?
They proposed a decentralized and
trusted cloud data provenance
architecture using blockchain
technology.
Blockchain-based data provenance can
provide tamper-proof records, enable the
transparency of data accountability in the
cloud.
Enhance the privacy and availability of
provenance data.

17. Recovery of
the
transactions
Cloud storage services can be
considerably cheaper as a
backup solution than that of
your own on-premise solution.
The method on which you
choose to move your data from
on-premise into the cloud can
vary depending on your own
infrastructure and
circumstances.
