integrate enough allowing them to coordinate independent activities when

necessary.

Intercommunication

The namespace in a smart contract is the way it can read and write world state

data to which it would not otherwise have access to that is enabled by calling

other smart contracts both within the same channel and across different

channels.

System Chaincode

Encoded within a chaincode are the domain-dependent rules for a business

process that are agreed between a set of blockchain organizations are defined

by smart contracts. U nrelated to these smart contracts for business processes, a

chaincode can also define low-level program code that corresponds to domain-

independent system interactions.

Privacy

Privacy is not a top concern for other networks but for the participants in a

B2B network, how much information they share depends on their needs, and

they might be sensitive about it.

If privacy is a key operational requirement, the Hyperledger Fabric uses

channels support networks and networks that are comparatively open.

Consensus

In the order of their occurrence within the network, the transactions between

different sets of participants must be written to the ledger. The transactions

order must be established, and for this to happen, the method for rej ecting bad

transactions that have been inserted into the ledger in error must be put into

place.

There exist with different trade-offs several ways to achieve it. Practical

Byzantine Fault Tolerance (PBFT) provides a mechanism where the file

replicas can communicate with each other to keep each copy consistent even in

the event of corruption. A process where competing computers race to solve a

cryptographic puzzle is mining through which the ordering in Bitcoin happens,

defining the order in which all processes subsequently are built upon.
