Tahoe Silicon Mountain, a network of entrepreneurs and professionals who live and work in the Tahoe-Truckee area, is pleased to welcome Jesse Myers to present at Mountain Minds Monday: “Blockchain: What it Is, How it Works, and Why It’s a Big Deal”
With the recent start of bitcoin futures trading, the world is abuzz about the cryptocurrency, bitcoin, and the blockchain technology it uses. Come learn and easily understand how blockchain works by participating in a simulation of bitcoin transactions with other attendees.
Jesse Myers, Principal of Protocol Capital, a cryptocurrency investment fund based in San Francisco, earned his MBA at the Stanford Graduate School of Business, where he first learned about blockchain and began personally investing.
Myers will explain the potential of blockchain technology, how it can disrupt the traditional industries that profit from non-blockchain transactions today and how you as an individual, business owner, or investor can leverage it.
Mountain Minds Monday will be held on Monday, January 8th from 6-8 pm at Pizza on the Hill, in Tahoe Donner located at 11509 Northwoods Blvd., Truckee. Pizza and salad is available and we use a pay-what-you-can model, if you’d like to have dinner ($5 minimum). Before and after the presentation, there will be time for networking.
The event will also be livestreamed and available online as it happens on YouTube: bit.ly/YouTubeTSM
This month’s event is sponsored by New Leaders, Holland & Hart LLP, Molsby & Bordner, LLP , Buchanan Law Group, and Mountain Workspace.

2. Blockchain: What it is, How it
works, and Why it’s a big deal
January 8th, 2018
3. Agenda
• What is a Blockchain and How Does It Work? – Exercise
• Why it’s a Big Deal – the potential impact of blockchain tech
• Questions
4. What is a Blockchain and How Does It Work? – Exercise
• Objective: Simulate how Bitcoin, or any blockchain, actually works
• Who is involved?
• Everyone in the room is a “User”
• We will take a look at a subset of four Users’ transactions for the exercise
• There are also several “Miners”
• What is the scenario?
• Everyone at the start of the exercise has $100 put into the system, recorded on the ledger as Bitdollars
• During the ensuing periods, the selected Users will send and receive money
• The Miners will each keep an updated ledger, to be broadcast to the whole room each period
• The whole room will vote on which ledger to follow at the end of each period
• This will all make more sense as we go along!

12. Blockchain Exercise – Additional Items
This example strips out most of the complex details of how blockchain achieves:
• Security
• Cryptography
• Digital signatures (simplified)
• Confirmation thresholds
• Trust
• Proof of work (simplified)
• Open-source transparency
• Synchronous, decentralized consensus
• Cost efficiency
• Low costs via revolutionary decentralized incentive structure (no centralized overhead, OpEx)
• However, Bitcoin is massively energy inefficient (and lacks a clear governance mechanism)
13. Blockchain Exercise – Implications
• The same result: trust
• A centralized authority is no longer the only way to create trust
• You can trust the decentralized consensus of computational work
• A fraction of the cost to achieve
• Order of magnitude cheaper
• In place of an entity, there’s just the cost of independent actors running software on their computers
• Suddenly, credit cards, banks, and other trust intermediaries are incumbents facing disruption
14. The components of a blockchain summarized
A blockchain is a DISTRIBUTED LEDGER formed by a CONSENSUS of SYNCHRONIZED,
SHARED and ENCRYPTED digital data, recorded in unchangeable packages called blocks
•Traditional systems rely on central
authority to generate trust
•In distributed ledgers, trust is
generated from the process itself
TODAY– CENTRALISED LEDGERS DISTRIBUTED LEDGERS

16. The Internet of Information
Blockchain’s potential is on the same scale as the Internet
“Blockchain could soon give rise to a new era of the Internet even more disruptive
and transformative than the current one.
Blockchain's ability to generate unprecedented opportunities to create and trade
value in society will lead to a generational shift in the Internet's evolution, from an
Internet of Information to a new generation Internet of Value.”
– World Economic Forum, June 2017

24. Summary of key points
• Trust via decentralized consensus
• No need for centralized authority to create trust between counterparties
• The Internet of Value
• Blockchain will be the foundation of the Internet of Value
• We may be in 1995 for this Internet of Value
• ‘Fat Protocols’
• In blockchain, value will be captured by the protocol layer (as opposed to the application layer)
• Possible to own a slice of the protocol layer (because the cryptocurrency is the medium of exchange)
• Blockchain will disrupt many established business models by:
• Disintermediating trust institutions
• Enabling lower cost operating models
28. Major investors are betting on blockchain; industry incumbents
beginning to leverage blockchain tech
INVESTORS ALLOCATING CAPITAL TO BLOCKCHAIN ENTERPRISES BUILDING BLOCKCHAIN CAPABILITIES
“[Blockchain] gives us, for the first time, a way to transfer a unique
piece of digital property, such that the transfer is guaranteed to be
safe and secure. The consequences of this breakthrough are hard
to overstate.”
– Marc Andreessen
“As these technologies develop, we can imagine total transformation
of the banking system, using blockchain, in a world where banks
don't really exist anymore.”
– Barclay’s
“Blockchain-based market networks will replace existing networks.
Slowly, then suddenly. In one thing, then in many things.”
– Naval Ravikant
“We see the new network models and data analytics capabilities [of
blockchain] as an exciting opportunity to reinvent treasury
management to better meet the needs of clients.”
– Capital One
29. An aside: Miners have two incentives
Coins commonly introduced to system as “block rewards” for Miners Transaction fees
• When users send a
transaction, they
include a small “tip” to
incentivize a miner to
include the transaction
in the next block
• Usually ~0.1%
