3. Who is Pedro?
• Director at Stork & Crow + CTO of Tykn (shhh!)
• IT architect with ~20 years work experience in 3
countries and way too many projects.
• Got tired of the corporate world, decided to
pause consulting and go back to coding and
writing _that_ book.

4. Tech stack hasn’t evolved -
just the service model.

6. Why?
• Because even the latest Web tech is still based on the same
ancient building blocks, now too far down the stack to be updated.

7. How?
• By creating a shared ledger that anyone can see but no one can
modify. That means you can’t be cheated by a toaster.

8. What?
• Blockchain is a planet-scale distributed and secure
database for digital assets.

9. Use cases

10. The internet is broken.
• Most financial and commercial activities are
processed on the internet. The same one where
cat pictures are shared between humans and bots.
• Personal information is rarely private once it’s put
online. See GDPR for more information.
• The internet was designed as a free collaboration
and information sharing platform, and it’s only
recently that “security” was put in place to prevent
it.

11. A new beginning

12. That moment when a teenager
reinvents computing…

13. Smart Contracts
• Vitalik Buterin designed a smart contract
platform as a critique to Bitcoin, said to be too
limited as programmable money.
• Smart contracts are computer code executed on
the Ethereum Virtual Machine (EVM), a single
computer distributed across the planet.
• So, if EVM is a “one world computer”, what else
could it be used for?

14. ÐApps
• Ð (ETH). As in Ethereum.
• Decentralised Apps. That easy.
• GUI interface in HTML + CSS + JS
• 100% available, anywhere in the world with an
internet connection. No server maintenance,
monitoring, security, or management required.

15. Web 3.0 - Internet Web of
Value
• The Distributed Web. A “internet” without middlemen,
DNS, virus, bad hackers, snooping or censorship.
• In addition to DApp features, Web3 uses messaging,
off-chain storage (IPFS) and computing (Golem),
data feeds (http://oraclize.it/) on a convergence path
with other technology trends such as IoT and AI.
• I believe the future of computing will be open, free
and decentralised. That means big tech companies
won’t be needed anymore.

17. DAO
• Or how to MVP democracy

18. Free Market 2.0
• Initial Coin Offerings - distributed venture capital
• Radical transparency - equitable information
sharing
• Peer to Peer
• Open. Decentralised.

19. Design _from_ the future
• Instead of moving the present ahead, further
layering on today’s legacy systems, bring the
future back to now. (Alan Key; adapted)
• It’s impossible? Unless…

21. Opportunities
Finance
• Key challenges include: arbitration, clearance, reconciliation, remittance, interoperability, trust,
transparency, ethics.
• Watch out for: Bitcoin, NASDAQ's Chain, Bitstamp for currency exchange and GridSingularity
for energy trading, Ripple for international settlements, Stellar for the underbanked masses.
Government (and governance)
• Key challenges include: Privacy, confidentiality, cooperation with "enemies", single source of
truth, ownership and trust.
• Watch out for: BenBen is doing a land registry in Ghana, in Sweden it's ChromaWay doing the
same. Estonia is still way ahead of everyone else though. Recruit can assure your
educational credentials, because not everyone is a real brain-scientist or rocket-surgeon, but
you might be and employers should be able to check.
Healthcare
• Key challenges include: Privacy, confidentiality, single source of truth, inverted economies of
scale due to compliance.
• Watch out for: Estonia, USA (again), Gem Health and Phillips, Bits + Blocks Harvard
Innovation Lab. Tierion won a Phillips Blockchain Lab award in this category.

22. More opportunities
Intellectual Property
• Key challenges include: Attribution, digital rights management, distribution, middlemen,
counterfeit.
• Watch out for: Resonate for music, Ownage for videogames, Ascribe for art.
Identity Management
• Key challenges include: Privacy, confidentiality, single source of truth, trust.
• Watch out for: Synereo for social media output ownership, Backfeed for reputation
management, Tradle for Know Your Customer, Uport for password-less web
authentication, while Authenteq and EtherRe.al are at the forefront of sovereign personal
data.
Infrastructure
• Key challenges include: Immutability, confidentiality, scale, security, trust.
• Watch out for: BigchainDB is probably where you want to start any PoCs relating to data
management, Namecoin solves DNS for IoT and Industry 4.0 scales, Ethereum will be the
world's biggest fog computer soon, Interledger is the best solution if you need to integrate
multiple blockchains together. If you want to tackle PKI, Pomcor is a good place to start
looking. Finally, you may want to look at Thunder if you are of the geeky persuasion.

23. Even more opportunities
Insurance
• Key challenges include: Trust, transparency, risk, claims management.
• Watch out for: Digital marketplaces for insurance as well as P2P insurance startups,
Tierion has some good ideas here too.
Supply chain
• Key challenges include: Ethics, sourcing, traceability, fraud, compliance.
• Watch out for: The IBM-Maersk partnership seems very interesting. Provenance is on a
quest to end fraud and fight blood diamonds so they really deserve a mention,
Chronicled aims at making retail supply chain more trustworthy or less sweat-shopy, if
you prefer
What system do you think could use a healthy dose of disruption?
What problem has never been tackled at a planetary scale before? (Tykn -
shhh!)
Keep up with #teamHuman, you may be surprised.

24. The best, for last
• Brexit - The City does some 70% of the euro-zone clearing for the EU. This will have to
change due to Brexit and the UK's decision to leave the ECJ jurisdiction. We could try to
replicate current systems in a new country OR we could implement a bitcoin-backed
international clearing and settlements system and change the world. - I’m talking about a
market processing billions of euros a day that could be run from some datacenter payed
for by all of our taxes in some nation's jurisdiction vs a EU wide network of "miners" all of
whom can be financially incentivised with transaction processing fees to add compute
nodes to the chain, so it's a foundation for a Universal Basic Income that pays for itself and
generates market value.
• Digital Job Twins - Lack of serious domain expertise for the various fields of human
activity is holding back blockchain development. Given enough caffeine and sugar startups
can create magic, but it will be when accountants, dispatchers, logistics experts,
economists, actuaries, and so on start getting involved that the technology will have the
same disruptive effect on the job market that the internet had around the turn of the
century. This is a job for #teamhuman.

25. Challenges
• Bitcoin changed the banking system, as it was designed to
do, but it’s consequences reach wider than currency into
law and governance.
• Governments fear that our right to privacy (Bitcoin) and
anonymity (Zcoin) will get in the way of public safety, while
ignoring the resilience to hackers and ransomware that
only blockchain can provide.
• Regulators and other middlemen see a threat where
technologists see the future; I think we’re looking in the
same direction so we must collaborate to design a future
that works for everyone. Crypto-UBI?

26. More challenges
• Bitcoin is said to consume as much power as
Vietnam, but no one has ever compared it to the whole
of the banking system, worldwide, which would be fair
to do since both have the same purpose and scale.
• Distributed consensus is hard and Bitcoin is fracturing
right now. This is relevant to all blockchains that use
the reference implementation as a basis.
• Mining is geographically concentrated and that
causes some geopolitical problems.

27. Smart Contract Use case
Title: Chargebacks with crypto-currencies
Description: Node1 enables consumer protection in an e-commerce transaction by enabling
chargebacks on pre-agreed conditions
Primary Actor: Node1 “Consumer”
Secondary Actors: Node2 “Trader”, Miner-Node, Smart-Contract
Pre-conditions: 1- Node1 has a commercial interaction with Node2 and uses system to make a
secure and legally protected digital payment
2- Node1 has required number of tokens to make payment
3- Node2 has parcel to ship to Node1 home address
4- Node1 and Node2 agree on Smart-Contract conditions for chargeback (as >10 days
for parcel delivery to Node1, >30 days without chargeback releases tokens to Node2)
Post-conditions: 1- Node1 payment is finalised
2- Node2 receives tokens for payment amount
Success Scenario: 1- Node1 uses system to make payment to Node2 via the Smart-Contract
2- System places tokens on a shared wallet for Node1 and Node2
3- Miner-node validates transaction and creates an auditable trail on the block chain
4- Node1 uses system to confirm arrival of parcel within 10 days
6- Miner-node validates transaction and creates an auditable trail on the block chain
Extensions: 2a- A multi-signature agreement would be required to transfer the tokens outside of the
rules of the Smart-Contract

28. Fiat currencies with unlimited
supply will lose value.

29. ICOs are hot
