BLOCK CHAIN TECHNOLOGIES
UNIT -IV
Introduction to Hyper ledger
• Hyperledger is a business blockchain framework designed for
infrastructure projects that need distributed ledger technology.
Hyperledger Burrow is an open-source blockchain framework that
handles transactions and executes smart contracts on a permissioned
virtual machine.
• Hyperledger provides the platform to create personalized blockchain
services according to the need of business work. Unlike other platforms for
developing blockchain-based software, Hyperledger has the advantage of
creating a secured and personalized blockchain network.
• It is created to support the development of blockchain-based distributed
ledgers.
• It includes a variety of enterprise-ready permissioned blockchain platforms.
• It is a global collaboration for developing high-performance and reliable
blockchain and distributed ledger-based technology frameworks.
• Difference between blockchain and Hyperledger:
Hyperledger is a blockchain implementation that is based on
open-source software. It was created by the Linux Foundation to
promote the development of cross-industry blockchain
technologies. The main goal of Hyperledger is to "incubate and
accelerate the development of open-source blockchain
technologies.
• TOKEN
• In the blockchain ecosystem, tokens are assets that allow information
and value to be transferred, stored, and verified in an efficient and
secure manner. These crypto tokens can take many forms, and can be
programmed with unique characteristics that expand their use cases.
• New tokens are created on a regular basis to meet the increasing
demands and use cases of each blockchain, and the creation of new
tokens is not expected to stop anytime soon. Token creators frequently
use “smart contract” technology to create digital assets while
maintaining the decentralization of their project.
Coin drop as a strategy for Public adoption:
• Airdrops involve crypto projects sending free tokens en masse to their
communities in a bid to encourage adoption.
• The adoption of cryptocurrency is much like the adoption of any other
technology: The rate at which adoption occurs grows very gradually
until about 8-10%, then generally explodes upwards to mass adoption
from there. We can characterize this general rate of adoption with the
phrase “gradually, then suddenly”.
• Currency Multiplicity:
• Cryptocoin multiplicity is just one kind of currency multiplicity in the
modern world. More broadly, we are living in an increasingly multi-
currency society with all kinds of monetary and non-monetary currencies.
• currency multiplicity in the sense of monetary currency in that there are
many different fiat currencies (USD, CNY, EUR, GBP, etc.).
• Second, there are many other non-fiat, non-cryptocurrencies like loyalty
points and airline miles. Now there is also a multiplicity of blockchain-
based cryptocurrencies like Bitcoin, Litecoin, and Dogecoin.
Demurrage currency:
• commodity money such as gold, demurrage is the cost of storing and
securing the gold. For paper currency, it can take the form of a
periodic tax, such as a stamp tax, on currency holdings. Demurrage is
sometimes cited as economically advantageous, usually in the context
of complementary currency systems.
• These firms typically calculate demurrage charges by multiplying the
penalty rate by the number of days past the time limit.
