ENOUGH ABOUT ME
WTF ARE BLOCKCHAINS …?
BLOCKCHAINS FOR DEVELOPERS
PART 01 - WHY DO WE HAVE BLOCKCHAINS …?
INTRODUCING THE ISLANDS OF YAP
YAP INTRODUCED THE WORLD’S FIRST PUBLIC LEDGERS
GROUP CONSENSUS WAS USED FOR TRANSACTIONS
● Size wasn’t everything
● The history of each stone
determined its individual value
● Conducting transactions quite
literally involved a song & dance
● This required the majority of people
from the village to be present
BLOCKCHAINS PROVIDE AN UPDATED TAKE ON YAP IDEALS
TRADING STONES FOR DOLLARS BASED ON GOLD
LET’S NOT FORGET THAT WHAT WAS ONCE PHYSICAL
IS NOW DIGITAL
PHYSICAL DIGITAL
WITHOUT PROPER REGULATION IT WILL CONTINUE FAILING
World War 2
US$3 Trillion
All other USA
wars combined
2008 Financial Bailout
US$8.5 Trillion
this inspired several
movements - including
the creation of bitcoin
VsBITCOIN
( the first application / popular digital asset )
BLOCKCHAINS
( underlying tech / shared public ledger )
VsETHEREUM
( open network for building anything )
PRIVATE NETWORKS
( very similar to traditional database )
VsPUBLIC BLOCKCHAINS
( enables permissionless innovation )
PERMISSIONED LEDGERS
( puts new central controllers into authority )
US$144 BILLION REASONS TO CHOOSE THE RIGHT CHAIN
11 BLOCKCHAINS NOW HAVE OVER US$1 BILLION MARKET CAPITALIZATIONS
THE ONLY CHAINS WE SUPPORT USE PROOF OF WORK
Data from CoinGecko on June 6th Bitcoin Litecoin Dogecoin Dash Ethereum ETC
Coin Limit 21 Million 84 Million UNLIMITED 22 Million Unknown 200+ Million
Current Supply 16 Million 51 Million 100 Billion 7 Million 91 Million 91 Million
Mining Algorithm SHA-256 Scrypt Scrypt X11 Ethash Ethash
Hash-Rate 644 PH/s 7.2 TH/s 6 TH/s 3.6 TH/s 30 TH/s Unknown
Average Block Time 10 Minutes 2.5 Minutes 1 Minute 2.5 Minutes 10 Seconds 10 Seconds

ALWAYS TRY TO REMAIN CAUTIOUS - JUST 60 DAYS AGO
Everything Else
(US$7+ Billion)
Ethereum X 2, Ripple,
NEM, Litecoin & Dash
(US$38+ Billion)
Bitcoin
(US$38+ Billion)
REALLY CAUTIOUS - 90 DAYS AGO
EVERYTHING
ELSE
BITCOIN
THIS IS WHY THIS GROUP IS NOT ABOUT THE CURRENCY
BUT RATHER THE UNDERLYING TECHNOLOGY
WHICH HAS CERTAINLY EVOLVED SINCE 2012
IT’S ALSO WHAT MAKES PROOF OF WORK SO SPECIAL
MORE ENERGY USED THAN THE COUNTRY OF ICELAND
SOLVING PUZZLES TO EARN THE RIGHT TO VALIDATE TXs
TRANSACTIONS ARE BATCHED INTO BLOCKS
● Transactions are batched into blocks every ten minutes (with Bitcoin)
● The block is added to the chain with a link to the previous block
● With the block added to the chain, its transactions are then confirmed
OCCASIONALLY - DIFFERENT BLOCKS ADDED AT SAME TIME
WHICH IS WHY WE HAVE CONFIRMATIONS
A NETWORK OF NODES WHERE THE LONGEST CHAIN RULES
THIS CAN LEAD TO A REORGANIZATION OF THE CHAIN
USE CASES
WHAT CAN WE DO WITH THIS TECHNOLOGY …?
SOME OF THE PROJECTS WE HAVE BEEN EXPLORING
BANKING
From AML & KYC cost reductions to
reward schemes & reaching the
unbanked or general key-signing
LEGAL
Cryptographically secure document
notarization, copyright protection,
and dispute settlement
GAMING
Share digital assets between an
entire network of games, or use the
blockchains to create immutable
persistent open-worlds
HEALTHCARE
Complete and immutable family
histories of every related diagnosis
and condition available from 1 key
GOVERNANCE
Increase the accountability of public
officials and offer total
transparency in voting & elections
ASSETS
Track possession of your property
in the digital economy by creating,
managing, storing, or sharing
multiple asset classes
ACCOUNTING
Creation of programmable processes
& automated auditing trails increase
transparency & efficiency
LOGISTICS
Tracking of shipping cycles and
provenance systems that
autonomously verify actions
INSURANCE
Integrated insurance and medical
services can be intelligently designed
to quickly and contractually settle
claims with cryptographically
AT THE HEART OF IT ALL IS DISTRIBUTED DATA
CENTRALIZATION
DATABASE
DECENTRALIZATION
THE CLOUD
DISTRIBUTION
BLOCKCHAINS
RANGING FROM PUBLIC STORAGE TO PRIVATE VALIDATION
● Blockchains can provide a tamper proof audit trail for structured data
○ Useful for public data (births, deaths, marriages and education)
○ Ideal for sharing data (identity, loyalty, supply chains and healthcare)
● Alternatively, blockchains can also be used to timestamp data hashes
○ Useful for large data sets (such as data lake authenticity checks)
○ Ideal for compliance (independently verify data timelines)
● Simple applications that require limited data can run autonomously without
the need to pay for and (or) service ongoing hosting or server requirements
○ Useful for operating censor resistant applications
LET ME SHOW YOU A SERVER-LESS DEMO
( HTML5 BLOCKCHAIN-BASED LOGIN SYSTEM )
NOTICE IT DOES NOT ASK FOR A CRYPTOGRAPHIC KEY …?
THE DATA IS 100% BLOCKCHAIN-BASED (BITCOIN, DOGECOIN and DASH)
available for as long as the network lives at no extra cost, no matter what happens to me
THIS PUBLIC DATA CAN ALSO BE ENCRYPTED PRIVATELY
TO BE CONTINUED IN PART 2
