• Wikipedia – “A distributed database that is used to maintain a continuously
growing list of records, called blocks. Each block contains a timestamp and a
link to a previous block”

3.
Double spend conundrum
• Double-spending is the result of successfully spending digital money more than once
• Blockchain for bitcoin made it the first digital currency to solve the double spending
problem without requiring a trusted administrator
• Protects against double spending by verifying each transaction added and ensuring that
the inputs for the transaction had not previously already been spent
• Uses a decentralized system, where a consensus among nodes following the same protocol
is substituted for a central authority

4.
Characteristics of blockchain
• Information held on a blockchain exists as a shared — and continually reconciled —
distributed database
• The blockchain database isn’t stored in any single location, meaning the records it
keeps are truly public and easily verifiable
• No centralized version of this information exists for a hacker to corrupt
• Hosted by millions of computers simultaneously, its data is accessible to anyone on
the internet

5.
Characteristics of blockchain
• Decentralized nature prevents control by a single entity
• Transactions are immutable (unable to be changed) and exist forever
• The blockchain network lives in a state of consensus, one that automatically checks
in with itself every ten minutes (new block creation)
• Eliminate third party intermediaries/overhead costs to reduce transaction fees, in
addition to settling transactions 24/7

6.
How is the network powered? (Nodes)
• Node – A computer connected to the blockchain network using a client that
performs the task of validating and relaying transactions) gets a copy of the
blockchain, which gets downloaded automatically upon joining the
blockchain network
• Every node is an “administrator” of the blockchain, and joins the network
voluntarily (in this sense, the network is decentralized)

7.
Why host a node?
• Incentive - the chance of winning cryptocurrency (proof of work)
• Nodes are said to be “mining” by solving computational puzzles and adding transaction
records to the blockchain (fees)
• Smart way to issue the currency (decentralized) and creates an incentive for more people to
mine
• Nodes use the blockchain to distinguish legitimate transactions from attempts to re-spend
coins that have already been spent elsewhere

8.
Bitcoin has been useful as a digital currency, but
merely stands as a one-trick pony. An idea was
envisioned for the blockchain to provide
functionality far beyond currency.
Enter Ethereum and Smart Contracts

9.
The future
is being
built as we
speak And it is
being built
on
Ethereum

10.
Build unstoppable applications
• Ethereum is a decentralized platform that runs smart contracts:
applications that run exactly as programmed without any possibility
of downtime, censorship, fraud or third party interference.
• These apps run on a custom built blockchain, an enormously
powerful shared global infrastructure that can move value around
and represent the ownership of property.
• This enables developers to create markets, store registries of debts
or promises, move funds in accordance with instructions given long
in the past (like a will or a futures contract) and many things that
have not been invented yet, all without a middle man or
counterparty risk.

11.
What are smart contracts?
• Computer protocols that facilitate, verify, or enforce the negotiation or
performance of a contract, or that make a contractual clause unnecessary
• Help you exchange money, property, shares, or anything of value in a
transparent, conflict-free way, while avoiding the services of a middleman
• Define the rules and penalties around an agreement in the same way that a
traditional contract does, but also automatically enforce those obligations
(code is law)

12.
The disconnected nature of un-trusted systems
manifests itself in the time required to fully close
out transactions

13.
With blockchains, the future of finance is
embedded in business process everywhere.

Fractional Ownership
• Why own a whole car if
you only use part of it?

15.
Now you have a platform with applications that run exactly as programmed
without any possibility of downtime, censorship, fraud or third party
interference capable of executing smart contracts.
What do we do next?

IoT Markets
Machines can be customers in machine-to-machine markets. Utilities, data storage, data usage, XaaS services,
and APIs are all services that usually offer rate limits or subscription models because charging on a per-use basis is
infeasible.With µRaiden, per-use charging finally becomes possible.
Pay-per-Use
Micropayments are becoming an increasingly attractive alternative to intrusive advertisement
and subscription walls. µRaiden gives users the option to decide on a pay-per-use basis
whether they would rather endure ads or pay for a premium experience. Customers would not
need to engage in the commitment of a monthly subscription model.

Germany’s Energy Giant Launches
100s of Ethereum Based Electric Cars
Charging Stations
“Tomorrow 100s of EV Charging Assets all
over Germany Blockchainified. E2E Product
using asset-backed Crypto-EURO for
payments,” before adding “our EV
Charging assets will be on public ethereum
blockchain and further assets across EU
connected soon.”
“By using a computer chip in the charging station, a smartphone app
to communicate with the interface, and a blockchain to manage and
record all of the payment and charging data, a fully automated,
worldwide authentication, charging and billing solution with no
middleman is created.”

Smart contract based trading solutions
• Turbine is powered off atAEP plant,
causing an energy shortage
• Traders determine pricing for power
and shortage is covered
• Instead, use smart contracts to define
pricing before an outage event
When the outage event
occurs, the smart contract
executes with the agreed
upon terms

26.
• In a deregulated market, electricity retailers buy electricity at wholesale price (in 1 MWh increments) and then
package and sell that electricity directly to consumers
• Retailers are not responsible for powering customers directly, but are responsible for metering and billing usage
• In addition to paying for generation, transmission, and distribution, end users also pay fees to their retailer
• These costs are largely comprised of marketing, administration, and managing risk/compliance for bad debts and
customer funds
• This can (and often does) add up to quite a large percentage, as shown by the average price of electricity in
various states in the following graph:

27.
• Grid+ is not interested in managing user funds or in settling bad debts
• Users prepay each month in dollars, which is tokenized on Ethereum as a dollar-backed
stable coin
• As a retailer, they have access to customers’ usage data, which gets updated every 15
minutes
• Every 15 minutes they query a customer’s agent (which can be any device capable of
making ECDSA signatures) for payment
• The agent signs a message sending a small amount of money over a state channel and
Grid+ takes a small fee from that transaction as a form of revenue

28.
gridSMART and AEP Energy Credits
• Tokenize user funds as a dollar backed stable coin
• Customers pre-pay or link bank account to convert USD to AEP energy credits
• gridSMART reads customer data every 15 minutes, deducting energy credits from customer wallets
• Users are able to monitor their energy usage in 15 minute increments, allowing greater visibility of energy usage
• AEP is insulated from bad debts and high-risk users through pre-pay model
• App teams are able to share data with ease using the distributed database model
