An Introduction to Blockchain


Published on

VCs have for the most part retreated from investing in Bitcoin and Blockchain. The appetite for blockchain products however has only increased. Corporations have formed consortiums such as R3 and the Hyperledger Project to learn more about the technology. Numerous enterprises have rolled out internal pilots to test and explore the applications of blockchain.

At Thomvest, we believe blockchain adoption is about to take off - making it a prime time for VCs to begin making early stage bets.

Take a look at our most recent research report which delves into the current state of blockchain.

An Introduction to Blockchain

  1. 1. An Introduction to Blockchain October 2016 1
  2. 2. Agenda Review of blockchain protocols: bitcoin, public, and private blockchains Assessment of adoption trends and notable players Appendix 2
  3. 3. Today’s transactional systems rely on outdated infrastructure to establish trust between parties 3 Computers enabled efficiency gains via databases and on premise computing solutions, dominated by SAP, Oracle, Microsoft, and similar companies 1970s: Internal Databases The Internet enabled a new generation of distributed platforms running in the cloud, enabling the outsourcing of certain processes and the more efficient storage of information 2000s: The Internet & Cloud Solutions With current systems, many transactional processes still require a third party to establish trust – such as an escrow, law firm, or clearinghouse – resulting in high costs, fraud, and inefficiencies Present Day: Inefficient Transactions Blockchains combines cryptography & distributed computing to deliver secure, direct peer-to-peer transactions without the need for a central party Think of it as another type of database for recording transactions What is a blockchain? Voting: Constituent votes cast via a blockchain code on a private device would offer immediately verifiable results Healthcare: Patient’s encrypted health information could be shared with multiple providers without the risk of privacy breaches Property Registration: A digital, transparent, and immutable land title registry can reduce land title fraud in countries like Honduras Financial Services: Faster, cheaper settlements could shave billions of dollars from transaction costs while improving transparency
  4. 4. 4 Think of blockchain as a transformative way to establish trust, transparency, and efficiency within P2P systems 4 A continually updated, network hosted ‘database’ of all transactions on a blockchain. Comprised of blocks of transactions (with metadata) chained together by cryptography Digital Ledger Programmed into each blockchain protocol, and responsible for verifying and updating transactions on the network’s digital ledger; not necessary in private blockchains Consensus Mechanism The good transacted on a blockchain; cryptocurrency provided the initial proof of concept, with the industry now looking to “color tokens” – i.e. any other form of digital asset Digital Asset Computing nodes with access to the blockchain, able to manipulate the ledger and view past transactions; may be pre-approved or verified by a consensus mechanism Network Participants A blockchain is a horizontal technology comprised of 4 basic components Data Source: Satoshi Nakamoto Whitepaper; Deloitte; CoinDesk
  5. 5. Bitcoin offered a PoC for blockchain by creating an alternative to fiat currency Bitcoin relies upon blockchain, its underlying technology, in order to transact a digital currency – cryptocurrency – between individuals without the need for a trusted central authority. Cryptocurrency is one of several assets that can be transacted on a blockchain, with different types of blockchains – known as “protocols” – offering different functionality 5 What’s in a block? All transactions are logged, including information on the time, date, participants, and amount of each transaction. How does it work? Programmed mathematical principles – the “protocol” - govern the method for verifying transactions and establishing consensus. Cryptography allows each participant on the network to manipulate the ledger in a secure way. Is it restricted to currency? The ledger can record any type of unit – currency, property, commodity, vote, rewards points, etc. – each of which is individually identifiable and programmable. Smart contracts build upon this. Core strength? Eliminates the need for trusted third parties, such as banks, governments, clearinghouses, accountants, and notaries Data Source: CoinDesk; pwc; Deloitte; Oliver Wyman Blockchain Proof-of-Concept 2009 Centralized Authority for P2P Interactions Various Blockchain Protocols, 2015+
  6. 6. The bitcoin blockchain lacks initial interest from early adopters given a variety of concerns 6 • Strict policy in Russia, the US, and other markets hinders expansion of key players, particularly given concerns over the use of bitcoin payment by illegal participants –Today, roughly 90% of mining operations and trading volume occur in China • Uncertain regulatory outlook presents risk for application-specific companies Regulation • Cryptocurrencies lack strong use-cases in developed countries such as the US, resulting in stronger adoption in countries with unstable economies, such as Argentina • Bitcoin is not a Turing-complete platform, meaning it lacks the programmability of other platforms such as Ethereum and private protocols Restrictive Use-Cases • The use of mining for consensus, albeit the most secure mechanism for public blockchains, reduces throughput, creating scalability issues for certain applications • Data privacy and security in the ledger presents concerns for sensitive information – particularly at nodes on the network, as with Bitfinex and Mt. Gox • Network updates are open-source and must be approved by a majority of miners Technology Constraints Insiders view a need for a compelling exit to re-validate the space and jumpstart investor and consumer trust in Bitcoin – many investors made their bets 3-4 years ago, and suffered significant losses and are waiting for returns Efforts to improve bitcoin’s scalability, such as Lightning Networks and Sidechains, represent notable progress, but early applications for blockchain remain heavily privatized Many founders express strong confidence in the need for a public blockchain, similar to the Internet Data Source: CoinDesk; Assorted Founder Calls
  7. 7. Blockchain protocols may be classified as either public or private – think Internet vs. intranet / IT 7 Public Private Access Open read/write access to database Permissioned read and/or write access to database Speed Slower Faster Security Proof-of-Work / Proof-of-Stake Pre-approved participants Identity Anonymous/ pseudonymous Known identities Asset Native assets Any asset Sample Companies PlatformSoftware Here, we describe platforms as enabling outside developers to build applications on top, while software is often run privately inside an organization Financial institutions (market operators, banks, etc.) are drawn to private blockchain solutions Data Source: CoinDesk; Assorted Founder Calls
  8. 8. Expanding the analogy, many insiders forecast a future of one public and several private chains 8 Internet / Intranet Blockchain Protocols Interoperability Public Private One rail, similar to the Internet Initial traction in risk-adverse internal systems Future: multiple chains per company from different vendors for each asset (like on-prem solutions)

Transformation of incomplete and inefficient public data records, such as property titles and voting, appear to represent early POCs of blockchain beyond financial services. Public blockchains exhibit stronger security risks than their private counterparts – not due to the underlying blockchain protocol, which has yet to be hacked, but rather publicly accessible applications such as the DAO.

  22. 22. Review of key risks when assessing blockchain companies 22 Infrastructure Constraints Many companies working in the application layer are building upon underlying infrastructure that isn’t ready with regard to scalability and security Minimal Real-World Viability Many use-cases are nice-to-haves that make little sense in reality for a variety of factors (e.g. authenticity for artwork, sneaker tracking for verifying authenticity) due to need for network affect, adoption cost, sales cycle timelines, etc. Slow Traction from Incumbents for Moon-Shot Implementations Many companies are trying for “moon-shot” implementations of the technology, which creates issues with long-stage enterprise contracts given a lack of trust around the unproven tech – hence, many of these approaches fail to mature from POC/pilot to production deals and live implementations, while ones that try to do the dirty work in less sexy industries, like Ripple, have been able to get their leg in the door Difficulty Converting POCs / Pilots to Live Production Deals Companies focusing on infrastructure struggle converting clients to production because they are “forcing” the technology on companies that don’t understand it, don’t clearly identify the need, or struggle with integration due to cost, time, and risk-adversity Limited Domain Expertise Many solutions companies in the space have no experience selling to enterprises, resulting in issues with taking their product to market and harming adoption Network Affects Transactions operate best when parties all run the same system – creating a need for network affects to kick in before a platform can take off; however, this is the chicken and the egg problem, since adoption will be slow until critical mass is reached Funding Considerations While insiders expect M&A activity to accelerate within the next 12-24 months – i.e. enterprise companies acquiring blockchain service providers to expand their product offerings – exit opportunities to date are marginal, made riskier given high valuations and crowdfunded projects, which complicate cap tables Data Source: Assorted Founder and Investor Calls
  23. 23. 2017 will mark an acceleration in live production deals by FIs in certain use-cases 23 • Driven by efforts to increase scalability, decrease latency, improve security, and drive use for asset transfer beyond cryptocurrency • Ethereum and Bitcoin appear to be the two dominant platforms Public Blockchains • Initially set up on-premise behind firewalls for deployments with sensitive data, as with Ripple Connect; hence, early adoption will be in low-risk, non-mission-critical transactions • Most organizations will eventually have several blockchains for different use-cases, similar to the large number of intranets from different vendors today • Interoperability between ledgers will become critical – this may require a public blockchain for inter-party transactions, or perhaps Ripple’s ILP will manage to meet the need • Within 2-5 years, new markets will emerge around blockchains, such as analytics of this new public data, new financial products adapted to this new enabler, etc. Private Blockchains Financial institutions and other customers are familiarizing themselves with the technology in risk-adverse use-cases on private blockchains Regarding verticals, financial services will be the first adopters, followed by insurance, healthcare, governments, and other regulated use-cases _____ "If 2015 was the year we work up to blockchain, 2016 is the year people are running their proof of concepts. 2017 is when you’ll see the first live applications. 2020 is when you’ll see significant adoption, and in 2025 we’ll see a tipping point in some markets. That’s 10 years out.” –CBDO of Digital Asset Holdings Data Source: CoinDesk

  25. 25. Collaboration drives the industry, while competition presents a long-term consideration 25 While many companies are targeting similar use-cases, customers, and channel partners, few blockchain providers have market-ready products, and thereby collaborate with other founders in order to prove the technology, educate customers, and facilitate adoption. Founders we have spoken with openly support this period of collective progress, and only expect to encounter competitive challenges once customer adoption expands beyond POCs and innovation labs towards production deals in 2017. Blockchain Solutions Shared Channel Partners Shared Customers Many developers and founders at leading startups – including ConsenSys, Eris, and Bloq – also actively contribute to the development of public networks such as Bitcoin and Ethereum. In many ways, today’s blockchain community is small and highly collaborative. Sample Study: Blockchain for Financial Services Data Source: Assorted Founder and Investor Calls
  26. 26. Early hype cycle enabled large raises, yet some companies struggled to deliver on product and customer integrations • Strong interest from enterprise customers results in long sales cycles paired with high burn rate for technical teams • Many operate in sectors prone to high compliance costs and regulation (e.g. bitpay), and sometimes even with unclear revenue opportunities given shifts in the industry Newer companies with strong emphasis on infrastructure exhibit ”scrappy” operations and long plays in the market • Small, yet highly technical and experienced teams keep burn low while the market develops • Developing beachhead markets via PoCs, “ambassador” companies, and channel partners for their technology as the groundwork to achieve a long-term vision Capital intensity varies widely based on timing, initial go-to-market, and company dynamics 26 1: Employees – costly dev teams, management, and sales teams 2: Compliance and regulation – key in heavily moderated verticals (e.g. currency, banking) 3: Integration – long timetable for enterprise sales paired with high burn necessitates large raises Typical Costs: Highly Capitalized with High Valuations Limited Funding, with Focus on Infrastructure Most blockchain companies fall in one of two camps: Data Source: Assorted Founder and Investor Calls; Pitchbook
  27. 27. Ethereum presents a compelling alternative to Bitcoin, albeit with notable drawbacks 27 Ethereum offers a powerful platform for smart contract applications, but remains in active development with large questions over the efficacy of its consensus mechanism following the DAO hack Ethereum Is The Most Widely Used Platform for Smart Contract Applications Unlike Bitcoin, it offers a high degree of programmability with its own Java-script-style language, Solidity, and is integrated with most cloud dev environments and consortia groups Ether Presents a Valid Alternative to Bitcoin The cryptocurrency Ether is the second largest by market cap (behind Bitcoin), and is traded on every major exchange globally Network Performance Raises Protocol Questions for the Non-Profit Developers of the ethereum protocol have been working to increase the network’s throughput and efficiency since its launch in 2013, with mixed progress (i.e. data sharding) Concerns Over Centralization Emerge After June 2016 Fork Following the DAO Hack in July 2016, the Ethereum community voted in favor of a “hard fork” to reclaim the funds – resulting in two active Ethereum blockchains and raising strong questions over the network’s security and decentralized nature Data Source: CoinDesk
  28. 28. Blockchain-based smart contracts present a new paradigm in asset registry and transaction 28 Data Source: CoinDesk; pwc; Deloitte; Oliver Wyman Smart Contracts Distributed Ledger (i.e. the Blockchain) New Business Models Real-Time Transaction Distributed (P2P) Provenance Regulatory Inclusive New Cash Products Think of smart contracts as a new form of registering or transacting assets enabled by the blockchain, which in turn may be manifested in new business models
  29. 29. Review of blockchain’s core benefits and risks - Permanent, transparent ledger enables increased transparency and auditability while reducing risk of data loss or conflicting records - High divisibility of ‘units’ facilitates fee-less micro-transactions - Higher efficiency and reduced friction through the elimination of centralized authority for P2P interactions lowers transaction costs - Public or private, depending on the blockchain protocol, with customizable permissions allowing sensitive data to be managed - Identifiable and programmable units enable smart contracts for more effective management of digital assets and offline P2P agreement  For instance, cash flows within a company’s departments may be programmed for specific uses within a certain timeframe, thereby reducing counterparty risk and securing compliance up-front - Elimination of single points of failure and reduced need for trust Key Benefits - Variable throughput capacity between blockchain protocols suggests an uncertain scalability, and potential concerns over transaction latency - Possible consensus protocol flaws, i.e. in the event of malicious agents on the network, may result in a lack of complete asset security - Uncertain regulations in certain use-cases, particularly those handling sensitive assets such as healthcare, securities settlement, and contracts - High deployment costs, particularly in data sensitive, complex data operations, may prove an inhibiting factor in blockchain adoption, and at the very least extend the timetable for deployment - Shift from centralized authority to an autonomous, digital, and decentralized network for trusted P2P transactions challenges societal and industry norms, and may face sharp resistance - Irreversible transactions (e.g. the DAO hack) Primary Concerns 29 Data Source: CoinDesk; pwc; Deloitte; Mastering Bitcoin

  31. 31. Illustrating the bitcoin blockchain protocol Jim owes Alice money for lunch. He installs an app on his smartphone to create a new Bitcoin wallet. A wallet app is like a mobile banking app and a wallet is like a bank account. To pay her, he needs two pieces of information: his private key and her public key. Jim gets Alice’s public key by scanning a QR code from her phone, or by having her email him the payment address, a string of seemingly random numbers and letters.* The app alerts Bitcoin ‘miners’ around the world of the impending transaction. ‘Miners’ provide transaction verification services in exchange for bitcoin. 1 All pending transactions in the past 10 minutes are grouped for verification. The miners verify that Jim has enough bitcoins to make the payment by completing complex cryptographic computations. Once verified, the new block joins the prior block so a chain is made – the blockchain. This provides an immutable and permanent audit trail to prove occurrence and timing of transactions. *Note: a bitcoin address is a hash (i.e. condensed version) of the public key to add an additional layer of security by not showing the public key until a transaction occurs 31 All the transactions in the block are now fulfilled and Alice gets paid. 22 3 4 5 6 7 Transaction Requested Transaction Authorized Transaction Executed & Recorded Source: Deloitte, PWC
