Block-Chain

What is Block-Chain?
• Block-chain is technology that enables peer-to-peer
transfer of digital assets without any intermediators
• Block-chain is growing list of records, called blocks
which are linked using cryptography
...

• By Design block-chain is resistant to modify data
...


The network of nodes
validate the transaction
using cryptography

Limitations for block creation and
consensus model
...

E,g, Block-chain for automobile
companies and healthcare
organizations

Initialize the Block Chain
•
•
•
•
•
•

Create First Block Manually
Must Contain All characteristics of block-chain
Nonce (Cryptographic hash generated random value)
Timestamp (Validation time b/w two blocks)
Several parameters must be specified
Create JSON file of it

Choose the right consensus Protocol
•
•
•
•

Implement right puzzle
Proof of stack or Proof of work
Secure chain from tempering
Adjust power of the network

Execute Smart Contract
• Business logic of the block-chain
• In case of ethereum, SC written in
solidity
• Contains the classes and functions used
through the block-chain transections
process

Debug and Scale
• Complex Process
• Blocks execute on set of nodes or
network terminations
• In case of open source code is
constantly evolving
