Курс 4 из 4 — Specialization Blockchain

This fourth course of the Blockchain specialization provides learners with an understanding of the broader blockchain ecosystem. Learners are introduced to other blockchain platforms, details of two decentralized application use cases, and challenges such as privacy and scalability. They are prepared to discuss permissioned blockchain architectures of Hyperledger and Microsoft Azure's blockchain as a service model and analyze the Augur and Grid+ decentralized application platforms. Course material includes emerging alternative decentralization models such as IPFS and Hashgraph, challenges in broader blockchain adoption, and continuous improvement solutions.

Decentralized Applications Platforms

We will explore two Dapps: Augur and Grid+ which are both implemented on Ethereum. You, too, can be a participant in these Dapps platforms, if you wish to do so.

The energy grid of the future.

In the past 10 years,

how many times have you seen a solar panel installation on a personal dwelling,

a windmill on a country farm,

advertisement for geothermal energy possibilities in a new housing development?

These are called distributed energy resources or DERs.

You're witnessing the proliferation of DERs.

You're indeed seeing energy production decentralization.

We're also witnessing the growth of major end-use electric devices.

A significant one is electric car,

another is a major development in Internet of Things,

IoTs and the advances in smart homes.

How do they manage the diverse demand at the user level,

to the decentralized production enabled by the abundance of DERs?

In the last lesson,

we added a production layer on smart contracts.

In this lesson, we add Grid+ that is

an accounting layer or Dapp platform for

the energy ecosystems on the smart contracts layer.

Shown here are four phases of the energy supply chain: production,

transmission, distribution, and retail.

Of these, Grid+ focuses on innovating

the energy retail sector with the integration of the blockchain technology.

There are opportunities for modernization,

improving efficiency, updating payment system,

and cost cutting for the end-user.

Field experts suggest that about 50 percent of

the end-user energy cost is not for electricity but for the administrative warheads.

Grid+ aims to minimize this with better technology and make

electricity grid cost effective, reliable, and robust.

On completion of this lesson,

you will be able to discuss the need for a smart energy grid,

explained architecture of the Grid+ system,

and explain the working of a Grid+ system.

What is a Grid+?

Grid+ is a blockchain Dapp platform implemented on Ethereum blockchain.

Grid+ has created an energy ecosystem by integrating

the blockchain and AI thus leapfrogging the energy economy into the modern era.

Grid+ aims to move

energy transfer and payment transaction onto the emerging blockchain architecture.

Grid+ pushes market signals to the end-users who can retain

control of their energy assets and make smart decisions.

This improves energy usage efficiency and also reduces costs to the end-user.

Grid+ provides a seamless payment system,

leveraging crypto tokens, thus improving efficiency in the energy payments system.

Have you noticed, it's all about disintermediation of the energy system.

Recall blockchain is about decentralization,

disintermediation, and distributed ledger.

What is regulated and deregulated markets?

In a deregulated electricity market,

market participants other than

the utility companies own power plants and transmission lines.

In such contexts, the companies that generate electricity,

sell electricity into a wholesale market,

and the retail energy suppliers purchase this electricity to sell it to the customers.

This deregulated electricity market offers an opportunity for

Grid+ to test its operational capacity and commercial viability.

These are the key ideas for Grid+, energy retailer.

Grid+ will operate as a commercial electricity retailer in deregulated markets.

The second key idea is that of a smart agent at the user or the customer household.

A Grid+ Smart Agent is

a computing device that hosts a software for blockchain transaction,

multi-signature crypto wallet with PKI security,

and off chain payments for faster confirmations.

Next key idea is the intelligent electricity usage.

Electricity trading is a complicated process with many intricacies,

Grid+ manages these by coding

efficient price options for the customers using smart contract.

ERC20 Token payments: A special ERC20 compliant token

called BOLT has been created for payment purposes.

Integration to Internet of Things devices,

IoT devices: A smart agent can be integrated into

other intelligent agents in a household like

NEST and electric batteries such as Tesla Power Wall.

Remote control: Grid+ enables integration of mobile phones and

computing devices to allow remote control of its operation.

Intuitive user interface that allows easy interaction with the system.

Even though blockchain and crypto token are involved,

the end-user does not require

any technical knowledge about the underlying infrastructure.
