An introductory guide to the blockchain industry (cryptocurrency included) that covers the industry's history, a know-how tutorial for cryptocurrencies, short introduction to the underlying technology, the major players in the Bitcoin network, and blockchain industry jargon.
FirstPartner's 2016 Blockchain Ecosystem Market Map helps to decrypt the blockchain landscape with a visual overview of the emerging ecosystem, players, technologies and trends. It clearly summarises three main areas of focus emerging around the core blockchain or distributed ledger protocols:
1) Bitcoin and Cryptocurrencies: Providing an alternative to centrally managed "fiat" currencies, this sector includes Bitcoin exchanges, Bitcoin wallets, miners and cryptocurrency payment processors. The map illustrates how these companies interact and features some leading players including Coinbase, Circle, Kraken and 21 Inc.
2) The Financial Services Blockchain: This has been the main area of focus over the last 12 months as attention shifts from Bitcoin to Financial Services applications. An increasing number of players are focussing on commercialising blockchain technologies for banks, securities, derivatives and asset markets and institutional investors - and are attracting VC funding to do so. Ripple and Ethereum are leading candidate protocols for payment processing and smart contracts and players including Ripple, Chain and Digital Asset Holdings are gaining traction with Financial Institutions. The Map highlights leading technology companies and some of the banks, card schemes and processors who are investing in or evaluating distributed ledger technologies.
3) Other Use Cases: The distributed ledger concept and its ability to support transparent and tamper-proof asset registration, proof of ownership and asset transfer transactions makes it potentially applicable to multiple non financial use cases. The Map highlights a number of candidate use cases including publishing, legal, distributed data storage, document management and IoT. Some of the pioneering initiatives and companies exploring these applications are included.
Crucially the Map also provides a clear pictorial explanation and summary of the leading protocols at the heart of the ecosystem and concepts including coloured coins and smart contracts that supplement them to make a number of the proposed services possible.
A printable version of the map can be downloaded from www.firstpartner.net.
I spent quite some time to digest how Blockchain works and how it can influence our everyday life in the upcoming decades. My slides focus on that from a non-IT expert point view.

Abstract:
With nearly six years of empirical data and use-cases behind the Nakamoto consensus method the community has observed that a cryptocurrency economy behaves differently than originally envisioned and intended. What has arisen from these half-a-decade of physical interactions is a nearly complete rollback of the primary attributes embodied within the first of these Nakamoto consensus protocols, Bitcoin – to the point where it may best to refer to it as Bitcoin-in-name-only (BINO). Consequently there are two other challenges within this existing BINO framework: (1) the diametrically opposed forces of speculative demand versus transactional demand; (2) decoupling coins from the ledger altogether. This presentation discusses several proposed solutions to the challenges currently being devised by a multitude of teams.
Content that helps to understand bitcoin and blockchain. Starts with currency basics, to clear the fact that bitcoin is not doing anything tangentially wrong. Followed by that bitcoin is covered and blockchain in detail.
Overview of bitcoin regulation challenges and opportunities.
The research focused on ineffective controls used by western regulators to control Bitcoin and cryptocurrency .
The Hive Think Tank: Sidechains by Adam Back, President of BlockstreamThe Hive
Over the last couple of years, blockchains have captured a significant mindshare of innovation in financial services, industrial Internet and digital commerce industries. The scope of applications of blockchain as a platform has long surpassed that of its origins in Bitcoin as a cryptocurrency technology. However, none of the new blockchain platforms has been able to reach Bitcoin's levels of scale, security and global reach. There have also been no standards to interoperate between different blockchain platforms for exchange of assets. In order to address these challenges, Sidechains were created as cryptographic systems that securely orchestrate exchange of information between different blockchains by leveraging the scale & maturity of the Bitcoin network. Sidechains are weaving a network of diverse blockchains to bring interoperability and Bitcoin’s scale & maturity. In this talk, Adam Back will talk about its role in building the decentralized world of blockchains.
Presentation of sidechains as Blockstream currently defines them (December 2014).

Metadata in the Blockchain: The OP_RETURN ExplosionCoin Sciences Ltd
With the addition of OP_RETURN outputs in version 0.9, it became possible to attach arbitrary pieces of information to bitcoin transactions. This turns bitcoin into a low-level communications protocol, just like TCP/IP, on which many new applications can be built.
Despite its powerful features, bitcoin is also limited, costly and inefficient compared to TCP/IP. After discussing which sorts of applications make this trade-off worthwhile, we talk about CoinSpark, a new open source protocol for enhancing bitcoin transactions, which makes extensive use of OP_RETURNs.
Bitcoin is a digital, decentralized, partially anonymous currency, not backed by any government or other legal entity, and not redeemable for gold or other commodity. It relies on peer-to-peer networking and cryptography to maintain its integrity. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending.
Welcome to the world of cryptocurrencies, the next step in the evolution of the means of value exchange. This is
the part where many authors would veer off into the fascinating history of money. Though that is or at least can
be interesting, it’s ultimately a side note — and one that, frankly, isn’t going to make you any richer.
Instead, this book will begin with and focus on what you need to know to participate in and potentially profit
from this white-hot frontier investment space. With that in mind, we’re not going to begin at the beginning and
regale you with tales of humankind’s early currencies or some such; instead, we’re going to take the leap off the
high board and start to teach you right away about the now and the newest computer-based currencies
Blockchain concept and technology. How this is becoming the next trend after the Bitcoin, expanding to a myriad of solutions. Smart contracts might be using a public distributed, and encrypted platform to support data persistence.

WHAT IS CRYPTOCURRENCY EXPECTED APPLICATIONS.
Since the introduction of Bitcoin in 2009 and cryptocurrencies in general, the use of digital currencies has
continued to grow. Early adopters utilized personal computers to complete the necessary steps that would result
in new digital “coins”. Commercial deployment of specialized mining servers, and introduction of mining farms,
followed shortly after.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing.

4. "First, a significant amount of work needs to be built on the “burn”
transaction before it is used to claim the coins on the other chain,
for the simple reason of avoiding DoS attacks. Then there is a
length of time called the quieting period during which the return
transaction and associated proofs are published, but not finalized,
and anyone else can step forward with a reorg proof and rollback
the transaction. Finally, there is a period of time afterwards
analogous to the coinbase maturity where the coins are not
spendable because a reorg could undo the peg transaction. So
that's three different waiting periods, each of which would
probably be in the range of 100 - 144 blocks, if not more. The
exact parameters are not set in stone at this moment, but with that
in mind we should expect a peg transaction to take at least 2-3
days to fully clear, depending on the final choice of parameters."
5. “Blockchain 2.0” Sidechain
Plan from Austin Hill & Adam
Back
Note: In theory sidechains can exist
without integrating through a merged
mining process
7. Working with mining pools
to discuss further utilization
and expansion of merged
mining
Merged mining will create
sidechains “firewalled” off
from Bitcoin main
Two-way pegging via atomic
transactions will enable
movement between
sidechains
8. Sidechains might not have blocks,
will include transaction fees to
incentivize miners
Will take 150-200 confirmations (2-3
days) to move between
“Reanimate” / “alchemy” / temporary
“burn” / Mario’s green pipe
Sidechains will be used for
experimenting with expanding
extensibility features including
user-issued assets, smart
contracts, HFT, and a plethora of
financial instruments

12. “To own ledger entry is to posses
knowledge of private key”
Tabulating publicly reported
bitcoins that were lost, stolen,
seized, scammed and accidentally
destroyed between August 9,
2010 and November 28, 2013:
803,285 bitcoins
• Note: hard to distinguish between bitcoins
which may have also been stolen from
thieves by other thieves
13. ◦ Since November 28, 2013 through April 1, 2014
5,800 PicoStocks
96,000 Sheepmarketplace
4,474 Silk Road 2
335 Pony virus
896 Flexcoin
1,454 Vircurex
950 Cryptorush
1,295 BIPS
484 Bitcash.cz
7,500 James Howell’s laptop
2,130 Proof-of-burn (Counterparty)
41,928 CryptoLocker ransomeware
◦ New total: 966,531 bitcoins
14. Coins stolen from mining pools (operator scalping/skimming)
Unclaimed or unused promotions and dust tips on reddit and Twitter
Coins stolen from insecure brainwallets (Naval Ravikant “Hello World”)
Dust on mining pools, exchanges and wallets
Intentional spam for taint analysis (1Sochi and 1Enjoy mid-February 2014)
Does not account for money or undisclosed bitcoins stolen off numerous
exchanges in which only fiat value is disclosed (e.g. GBL platform, $4.1 million
in user money November)
Ransomeware copycats (CryptoLocker 2.0, CryptoDefense)
Accidental destruction transferring to temporary addresses (i.e., many
exchanges will issue new deposit addresses, sending tokens to same address
even minutes later could result in permanent purgatory and/or destruction)
Marginal cases of mining and forgetting key or throwing away laptop (e.g.,
Stefan Thomas, James Howell). Hal Finney remembered to back-up, did you?
Jaded spouses / OTC
15. In February 2014
bankruptcy filing:
Customers lost 750,000
bitcoins
Mt. Gox lost 100,000 bitcoins
of its own
March 20, 2014 announcement
claims they have “found” 200,000
in a wallet the company no longer
used
16. By 2013, generally accepted belief that approximately 1
million bitcoins have been lost, stolen, seized, destroyed
Between 2010-2013 18 of 40 exchanges closed, often wiping out customer
balances
“Trust-me” silos
Tabulations on previous slides provide evidence this is the
case
Adding Mt. Gox estimates brings this to approximately
1,650,000 bitcoins
◦ 13.1% of all bitcoins based on assumption of partial-recovery
If all Gox coins recovered, then closer to lower bound of
10%, if less recovered then closer to 15%
17. Mining estimates from ‘rutkdn’ and OnBitcoin:
1,919,950 bitcoins are stagnant on 38,399 addresses mined
between 2009-2010
Roughly half of these are known to belong to Satoshi (see
research from Sergio Lerner)
Other half belong to miners who:
Hard drive broke, returned-to-manufacture and forgot to backup
Mining as a hobby on old equipment, hard drive now long gone and/or deleted
Sent dozens even hundreds of bitcoins to test it out with other hobbyists, then
deleting them because they were “worthless”
This alone represents 15.29% of all mined bitcoins as of April 14, 2014
18. According to Jonathan Levine:
“Post 2012, the amount of
coins held in addresses
containing between 50 to 100
BTC are above my expectation
and raises the possibility that a
large number of these coins are
lost. This conjecture is backed
up by Bitcoin days destroyed
evidence. There remain
approximately 4 million coins
that have never been spent,
many of which are probably
contained in the red section.”
19.
20. As of block 295,000,
approximately 99.08% of
all addresses contain less
than 1 bitcoin
Actual amount located on
these addresses is
109,119.9 BTC
This accounts for roughly
0.86% of all bitcoins
mined as of April 12, 2014
21. At least 10% are reportedly known to be lost, stolen, seized,
destroyed, scammed and forgotten
Mt. Gox could add another 5% if all “disappeared”
Another 15.29% of mining rewards are stagnant or gone
0.86% reside on over 32 million addresses and most may
never be used
Thus at least 30% of all bitcoins are either lost, stolen, seized,
destroyed, scammed, “dust” or forgotten (perhaps
intentionally)

24. Solutions:
◦ Trezor (2FA)
◦ Proof of reserves from Bitfoo
◦ Insurance from Xapo (via Willis)
◦ Oracle and HDM wallet from
Cryptocorp and BitGo (BIP 32)
m-of-n/multisig (BIP 11 & 16)
◦ “On-chain” wallet from
Blockchain.info
◦ Armory (near impossible to hack
but need to be a geek)
◦ Sidechains/blockchain proliferation
◦ Paperwallets (*)
Note: As of April 14, 2014, none of
the Top 500 addresses currently use
multisig on-chain
25. When smart contract platforms arise, same type of vulnerabilities exist,
yet stakes are higher.
Example: Alice goes to bed. During the night, Bob from Hack Island,
breaks into her laptop and email account, stealing her digital keys that
control her bitcoins and most importantly the smart contract “deed” to
her home. During the night, this contract is sold and resold a dozen
times on a decentralized exchange. Alice wakes up, unable to open her
home because the door is synched via wifi to a cryptoledger. What does
she do?
Go to court, explain that even though there is a perfectly unabused
contract, signed in a cryptographic manner, the “legitimate” bearer has
been robbed and the contract should be ignored. New lock and title
issued and installed.
26. What if several days, weeks or months
past before original “legitimate” owner
realizes their boat or summer home has
been resold and sold again and last
owner is an orphanage or church?
Current case law may exist but in some
cases new precedents could be set.
Preston Byrne: “Utilize trusted third
parties (TTP) to create trading limits
much like payment processors do
today.”
Integrating trust – as a variable – into a
decentralized prediction market?
27. How to incentivize the use
blockchains or sidechains internally
at Coinbase and other
exchanges/wallets?
Could exchanges run a sidechain?
Other uses-cases for securing
tokens and on-ramping new
adopters
◦ UI/UX
◦ Providing real economic growth and
value (e.g., non-illicit activities)
36. Tipping is more like a faucet or ‘interpersonal transfer’
“Fun” way to redistribute existing tokens yet not linked to
actual utility/value of a service performed (i.e., arbitrary)
“[T]he hard truth seems to be that tipping does not work. It
does not benefit the customer. Nor, in the case of restaurants,
does it actually incentivise the waiter, or help the restaurant
manager to monitor and assess his staff. The cry of stingy
tippers that service people should “just be paid a decent
wage” may actually make economic sense.”
