1. The document discusses implementing blockchain using cloud computing. Blockchain provides a distributed ledger and enables secure transfer of assets without intermediaries. It consists of blocks, miners, and nodes. 2. Several research papers are reviewed that propose using blockchain for data provenance in cloud storage. Blockchain can provide tamper-proof records and transparency of data accountability. It also enhances privacy and availability of provenance data. 3. Implementing blockchain using cloud computing provides benefits like better decentralization, efficient ownership tracking, increased data security, faster disaster recovery, and geo-independence. Security challenges like 51% attacks are also discussed.

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.
Blockchain

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.
