Smart property is property whose ownership is controlled via smart contracts that may or may not reside on a cryptoledger. Yet my doubts as to whether these projects will succeed are unimportant because the wallets of market participants collectively will decide what will succeed and what will be purged. Our developers have been aware of the issue for a long time. Bitcoin is a perfect microlending platform in that its 8 decimalization units provide flexibility for fractionalization and the transmission is both secure and relatively fast. There may be a number of start-ups running in stealth-mode that are developing these solutions, however, besides exchanges, there have been few if any public launches or investments in cyrptocurrency start-ups. Thus, in practice Bob may actually have a publicly traded account that he publicly lists on business cards, websites but then he may have several other digital wallets in which he actually stores all transactions, savings and revenue.

We appreciate your feedback. You can read this item using any of the following Kobo apps and devices: In order to modify or fulfill its task, it must receive a certain threshold of digital signatures from keyholders e. Even with some froth that has arisen, greater functionality is coming, with a clear consensus emerging that this technology will reduce friction — and overheads — for business if thoughtfully designed for financial applications.
Some platforms may succeed, others may fail — it is entirely possible that the platform which will introduce this technology into the mainstream has not even been coded yet. If you, the reader, are now asking yourself: The goal in writing this guide is to provide readers an overview look into an often-hyped, but nonetheless dynamic and rapidly-moving area in technology, law, and commerce, and in writing this guide I have tried to be as unbiased and diplomatic as I can, giving equal time to different viewpoints, approaches and platforms.
What they all share is enthusiasm, which can be found in abundance on the part of developers, entrepreneurs, investors, and thinkers alike. Where existing protocols all pursue ambitious goals, they remain subject to significant — and known — technical limitations and, at least to date, a lack of funding and manpower to address them.
If the goal of cryptoprotocols is to provide frictionless mechanisms to foster real economic growth, then creating applications that provide genuine increases in productivity to end-users that replace expensive existing infrastructure is likely an area for ripe business development e.
How, then, can firms tap into the wider consumer ecosystem — where cryptoprotocols have not yet seen widespread adoption? Some veterans in the sector suggest entrepreneurs who are new to the space initially work on projects that do not have high compliance overheads — such as exchanges or money transmitting business — or to look at different geographical corridors to address the needs of the unbanked and underbanked in the developing world.
Alternatively, others suggest focusing on purely commercial applications, in high finance or in business-to-business platforms, due to the complexity of money laundering and consumer protection laws which apply when dealing directly with the general public. Perhaps being a software provider that does not hold the tokens, or exchange tokens for fiat, could be a safe middle ground or creating easier point-of-sale merchant accessibility with QR codes.
Or as Sean Percival suggested, redesigning interfaces for consumers so that cryptocurrency becomes more accessible. There is also a growing impetus to build bridges between existing financial infrastructure and cryptoprotocols.
While enormous amounts of capital human and financial have been invested in this space, some projects are likely redundant — reinventing the wheel as it were — and others may be based in political, rather than commercial, motivations. Anyone wanting to get involved in his space should therefore ask: Is building another proof-of-work-based blockchain an effective use of resources or can your team sync your features to an existing ledger? Is it possible to provide new value to larger customer bases without having a Turing-complete protocol?
Do you necessarily need to use a decentralized processing framework instead of a distributed or even centralized in the case of intranets systems?
Can your development team work remotely, reducing overheads, or do they need to be located in a specific office or housing complex? Can formal partnerships with existing market participants be forged to secure more funding and better cater to their needs?
Instead of having to stand in one location to call another fixed location — as the landline-era has conditioned us to think of commerce — decentralization brought about by mobile phones enabled users to call and connect with specific individuals from anywhere.
Smartphones and tablets subsequently opened up the ability to perform and use productivity apps, empowering new demographics to utilize virtual offices, leapfrogging the need to use traditional brick-and-mortar office parks. Cryptocurrency is similarly disrupting the way we use money and, more generally, asset management. It is one of the few areas over the past twenty years that has not been radically transformed by new digital technology — but this will likely change, as both Naval Ravikant and Eli Dourado recently analogized, Bitcoin is not money — it is the internet of money.
On the other hand, Bitcoin and its progeny empower individuals to be their own financial institution — much like how Linux platforms enabled ordinary users to potentially utilize more powerful use-cases than Windows. The interviewees for this book — and indeed all of us — are participants in an unprecedented, cryptographic, mathematically constrained experiment that is likely to impact nearly every industry. Yet it is clear that decentralization is not necessarily the answer, the silver-bullet or panacea to every economic problem; it is merely a tool, a solution for some things, but not for all, and corporations, organizations, firms and institutions can still benefit from the technology while employing centralized management systems e.
Furthermore, skepticism is warranted for bold claims about specific future events such as the need to reinvent the ledger-based wheel with a flavor of the month. For every project listed here there are two or three more that could have been surveyed and analyzed. As Carl Sagan once said, extraordinary claims require extraordinary evidence. And based on my interactions with the teams detailed above, I believe that many if not all of them are capable of achieving the milestones and goals they have set.
While decentralized apps geared towards illicit markets may be popular and profitable with certain segments and niches, the key to mass adoption will likely be providing real value by addressing real needs e.
Each of these platforms, even the 1. Yet, despite the hype and promise, it remains nonetheless entirely plausible that the technology may not meet the expectations of its most zealous advocates, and the only decentralized app that is still popular a decade from now is still relegated to the world of peer-to-peer torrents.
It is my view that cryptoledgers have the potential to make smart contracts, smart property and trustless asset management a reality for all. Can Bitcoin do everything? They are not mutually exclusive and are all part of the larger cryptocurrency ecosystem. Another way to think of it is Bitcoin is a specific reference implementation of Cryptocurrency but not the definitive technology as it does not solve all the problems, otherwise nobody would care about Ethereum, Mastercoin or Counterparty.
And as a consequence, immutable algorithms employed by these improved DACPs and cryptoprotocols empower users to choose their own parameters, boundaries and even create voluntary associations.
Levine also sees Bitcoin as a type of highway and the other platforms and protocols as off-ramps. Yet, in time other protocols could also become highways and thus an interconnected series of decentralized, encrypted highways would transmit and track value globally in a frictionless manner. Perhaps they will fork the winner and start from there. While not everyone agreed with method or path, the one common theme from everyone who provided insights to this guide was: Nearly each person I spoke with had started a company in the past and experienced failure first hand.
Do not let that stop you from trying a different approach. Learn from your mistakes and be open to changes. While the Bitcoin protocol has grown immensely in the past five years, it is still quite young in terms of market penetration. At the time of this writing, the market cap for bitcoins all The potential market cap for all trustless asset management is the same sum total of known assets which is several orders in magnitude larger; the key difference is how they are managed and transferred.
Some assets, such as deeds and collateralized loans, are easier to encode as a smart contract; others may be more difficult. Similarly, existing blockchains are limited in terms of what secondary attributes they can store e. With the knowledge of the previous chapters, the question that decision makers, executives and business development managers should ask is, what can cryptoledgers or smart contracts solve for large organizations with established networks, retail operations, or mobile assets?
Time-stamping and HR automation have already been discussed, as have customer-reward programs like frequent-flier miles, so what about monitoring car fleets? Or perhaps Bitcoin is not needed to perform every function; perhaps it will serve as a bridge for some, but not all virtual exchanges.
At this time, while it is very good for remittances, Bitcoin is not a competitive payment system for many parts of the world. It can be used, but it is not ideal. This is because the confirmation rate of its currency bitcoin is too slow and relatively expensive — the transactions per second has lagged behind the price.
Similarly the protocol is less than optimal in most transactional settings because it is cumbersome, not Turing-complete, and not intended for this specific purpose, preventing developers from building transactional and contract systems, services and applications on top of it.
As a consequence, its usability is still extremely limited for most mainstream payments such as point-of-sale; and software and infrastructure must be deployed to take it to a network capacity of s or s of transactions per second instead of the current 7 per second.
This situation may be temporary and could take a few years to resolve — and at that point perhaps we will see payment adoption take off but this would require substantial changes to the protocol. For example, perhaps by that time blockchain pruning SPV will be implemented to eliminate all spent outputs from the blockchain shrinking it substantially.
It should be noted that the direct comparison is not entirely apples-to-apples either as the Bitcoin transactions in this chart only include on-chain transactions.
An off-blockchain solution also allows users to trade below the dust limit roughly satoshis which is an artificial limit implemented by the developers several years ago to prevent spam from propagating the network e.
BTC-e takes this off-chain approach a step further by allowing users to build bots that interact with its API, enabling high-frequency trading.
None of this is possible on-chain and thus these types of transactions are not represented in the image above.
For example, Bitcoin currently has a hardcoded block size of 1 MB, or 7 transactions per second. Again, this may not be an issue in developed countries, where users have easy-access to Bitcoin wallets both web and mobile based. In fact, despite the fact that it takes 10 minutes for one confirmation, it is still quicker than other existing remittance processes such as ACH which can take three days to clear.
While credit card companies like Visa can make the clearance of payments even offline they download the blacklist on terminals and M-PESA is quick and easy via SMS, the slower confirmations are a challenge for Bitcoin as it makes its way into the mobile payments space. Readers may be wondering just how many users actually use Bitcoin or other cryptocurrencies. Because of the decentralized nature, it is a difficult answer to actually provide.
In addition, it is difficult to differentiate between those who have exchanged a fraction of a bitcoin at any time and those who are actively using bitcoins today. For instance, according to Bitcoin Pulse, the number of cumulative individual wallet downloads hosted at Sourceforge is 5 million; yet as shown below, this is not the only type of wallet users have access to.
In addition, readers should keep in mind that a user of bitcoin can be defined as a user even if the amount they transmitted is a little as 1 satoshi 0. Again, this does not necessarily mean that only individuals own roughly one-fifth of all bitcoins. For example, some of these addresses belong to large exchanges and web-based wallet services such as Coinbase and BitStamp.
Because these customer wallets are off-chain it is impossible as an outsider to know exactly how many people actually own and use bitcoins behind this wall. Coinbase now has over 1 million customer wallets and it is unknown how many of these users actively trade and use bitcoins with other internal services.
Yet, there is likely a liberal upper bound estimate of roughly 10 million users on all platforms in the ecosystem today. There are two ways to derive this number, the first is from the fact that there are roughly 10 large web-based exchanges. If each of these has one million users, which they likely do not, then that is approximately 10 million users. Another way to derive the 10 million is through the limitations of using microtransactions directly through the blockchain.
Because of anti-spam provisions know as the dust limit, users currently cannot send less than satoshis on the blockchain directly, otherwise that transaction is not incorporated into a block. For users in developing countries looking to conduct in commerce and or even remit with bitcoins, there are few formal exchanges based in these regions.
Thus they will likely use on-chain wallets and if they use on-chain wallets their transactions will be limited to sending bitcoin values above this dust limit. As of this writing However, it is unknown how many of these addresses are actual active users or how these are abandoned addresses e.
Usage rates of many other cryptocurrencies follows similar patterns. This dearth of fiat-to-cryptocurrency exchange in emerging markets presents a business and educational opportunity for entrepreneurs such as bitcoin ATM providers as discussed later in this chapter. In fact, centralization of information and assets can and is oftentimes easier to manage in most industries.
Just because Bob stores data in a centrally managed Amazon cloud server, does not make his enterprise any less effective. In fact, the code probably runs much quicker due to how AWS can scale e. Perhaps the opportunity costs of keeping the existing system are less than switching and managing another.
Similarly, others have explained to me that making a product easy-to-use should not be the penultimate goal either; rather, developers and entrepreneurs should instead answer these questions: What problem does this solve?
What need does this satiate? Why should others use it? Bob could extol the virtues of cryptocurrencies to his relatives and convince them to purchase bitcoins or dogecoin as a speculative investment, but what would they use it for in their daily life? How does it make their life any better or easier?
Just because you can decentralize, should you? These are the kind of questions that start-ups in this space need to answer. This insight could save many people a lot of headaches in the future.
Instead of forking code and reinventing the wheel, several sources I spoke with think developers should learn from the mistakes of the open-source community fifteen years ago. Where there were endless Linux distributions being rolled out and semi-funded, each had technical advantages, yet few could convincingly provide a solution to specific problems and garner mass market appeal.
And ultimately after years of consolidation and market purges, the most popular Linux-based end-user package was not Ubuntu or Fedora, but Android — which simultaneously satiated customer demand and solved needs in an easy-to-access manner.
What is the burning need? In cases such as maintaining IT infrastructure they could in fact create higher costs or produce negligible gains. One investor explained to me that while critics are right to point out that there has thus far been a limited buy-in of mindshare of these new technologies, they should also acknowledge that existing system today replaced other systems and so on.
Whereas previously brokers traded on the exchange floor, electronic traders were viewed as outsiders and the floor traders were the insiders. That role has reversed in a matter of decades. Like the horse-and-buggy before it, any new disruptive technology will seriously impact the landscape creating winners and losers. What entrepreneurs need to try and figure out is how they can position their firm to get on the winning side. Maybe it is blockchains, maybe it is consensus ledgers, maybe it is something else entirely.
Too much of a good thing, however, can be problematic. While a lightweight proof-of-stake or Ripple-based cryptoledger could be used internally by corporates to replace auditors and accountants e. Unlike the Internet, intranets are based on centralized network controls where all actors are known and all actors are already constantly monitored and there is trust. Because trust is enforced by administrative oversight, the problem of tracking financial and other assets is suitably addressed for normal commerce by existing technology.
With this technology, inventory systems that could be compromised and abused might instead be replaced with cryptoledgers. If Bob owns a large media store, he could manage and track all of the books with embedded RFID tags; instead of building and trying to maintain a relatively costly proof-of-work infrastructure e. The cryptoledger could itself be managed by a DAO which then connects it to a larger corporate VPN to franchise locations and vendors in the supply chain, each of which have their own ledger and so forth.
Again, the token itself is unimportant from the perspective of human agents; it is not used for some value-based exchanges but for internal bookkeeping and rationing.
In all likelihood, if a cryptoledger is used internally, the tokens would all be premined. Another example of where the technology might be applied would be automobile dealerships and car rental facilities. If Alice runs a Hertz franchise she could install a proplet a MEMS device that can interact with smart contracts and cryptotokens , with which she could control the operation of a vehicle based on the lease agreements — including reverting control of the vehicle to a new owner all via a cryptoledger.
A cryptoledger, on the other hand, removes the necessity for 3 rd party involvement. For example, Hertz could implement an internal proof-of-stake ledger at each location, and a DAO would connect the ledger via a VPN to the parent company. Each car ignition would be fitted with a proplet that can communicate with the ledger via a cryptographic handoff a token of some kind , and therefore any customer or owner could use smart contracts to pass ownership off to other approved individuals.
Consequently, neither Alice nor Bob are locked in within any specific vendor of cryptoledgers, as these systems are currently open-source. Furthermore, because a DAO manages the edge of the network, they can work with decentralized exchanges that enable customers from any part of the globe to transfer one type of cryptocurrency for a cornucopia of tokens representing thousands of assets, thereby creating a frictionless environment for decentralized commerce.
But would the cost and unfamiliarity of adoption of cryptoledgers over existing technology which serves the same purpose be worth it? It is probable that for smaller businesses the opportunity cost — the new skill sets which employees would need to learn — might be prohibitively high, particularly given the dearth of software tools available for the technology.
Some, however, see that businesses with sufficient scale might be employ cryptoledgers — sooner rather than later — for strategic applications of a capital-intensive nature, such as obtaining funding from the capital markets, as Preston Byrne suggests in chapter 2.
In a broader automobile lending context such a system could be used by any lender to dramatically reduce servicing costs while providing considerably better loan-level data to prospective investors. Thus the opportunity costs, the seen and unseen of implementing and maintaining a decentralized cryptoledger should be taken into account.
Similarly, at some point traditional players could enter the market when cryptocurrency has enough traction and either build something themselves or try to buy the new established players. They also started with basic protocol and infrastructure levels and built up from there to the more sophisticated services once the basic layers were settled and established.
It is sort of a similar story here. You cannot aim too high at the beginning since the basic building blocks are still not in place. Also, even though you might be anticipating the right services and needs — your timing might be off. The sweet spot might be still years away — even though the technical capabilities could be in place. There is going to be a lot of trials-and-error, and huge amount of luck involved, for some. The trick is to try and monetize throughout the journey.
For instance, the most boring applications may be the most profitable in the beginning; like a financial back office and corporate administrative solutions providing the biggest savings in the first phase. Market participants should also be aware and cognizant of regulatory bodies and policies — they do play a role in the development and deployment zigzag.
And different governments have different incentives and approaches to the matter. Mundane applications such as tracking inventory or coupons as described in chapter 5.
Perhaps integrating a CRM API with a ledger could allow companies to track customer sales, or as mentioned in chapter 4, figuring out ways to integrate EDI with a ledger could likewise enable robust and secure supply chain management with all vendors. And there seems to be so many nails all over the place, or at least that what they seem to see. Similarly Orkut was incredibly popular with specific countries like Brazil and India but was completely passed over by the larger social networking consumer-base.
In many ways, these platforms being built today could start as a Napster but end up as iTunes. Kajander and several others I spoke with, see an intersection between cryptoledgers and non-profit organizations as well.
As noted in chapter 5, there was a notable example of fund mismanagement in China related to the Sichuan earthquake. Perhaps even a Kiva and Bitcoin-like mashup could emerge for similar emerging markets. Other charities could benefit from this transparency as it also reduces administrative overhead by removing the need for several functionaries. So in the future, having elections could be as easy as each user submitting their digital signature for a particular policy or candidate and the election could be both quickly verified and difficult, if not impossible to cheat.
Voting is not limited to national elections either, as villages, classrooms, any organization could use a token-based cryptoledger system to provide a transparent mechanism for the electioneering process. All someone needs is access to a mobile phone or laptop. Specific examples could be community organizations that hold votes to release funds to improve hospitals, schools and libraries. Coupled with the assurance contracts discussed in chapter 2, voters or voiceholders as Adam Levine describes them, could review the votes and act on the consensus.
Thus as Kajander and Hakim Mamoni have explained, you can remove middlemen, bureaucracies and allow direct involvement between two or more parties e. Another way that for-profit companies can utilize this token system is through a matching campaign. In an offline situation, the product could have a scanable QR code that serves the same function.
They can then be sent to a charity or NGO of your choice and Nike will redeem and donate a certain amount of prearranged money to the recipient. At a basic level there appears to be a lack of clear property rights and contractual rights in China. While some jurisdictions like Shanghai are more transparent and modern than others, no one actually owns property for more than 70 years, after which it is automatically reverted back to the state.
Furthermore, at any given time some of these titles can be revoked or modified by a 3 rd party without due recourse. As a consequence, despite reforms over the years, land confiscation is still common. For example, each year approximately four million rural Chinese are evicted from their land. While it remains to be see how policy makers will react to these new innovations, these cryptoprotocols could provide new tools for everyone to reduce costs and secure value.
Despite all its volatility right now, cryptocurrencies may actually prove to be a better choice than politicized money in some developing nations. Robbery is common, especially in poorer neighborhoods. Cryptocurrencies could be a safe alternative to store your savings. As noted earlier by Alan Safahi as well as Wences Casares and Sebastian Serrano, one of the areas that cryptocurrencies can already disrupt is the remittance marketplace.
In , approximately 1. Perhaps something like a debit card could be loaded from the U. There is a huge market opportunity here. And how does this tie in with the rest of the guide? What if law and governance is just a technology like any other? Smart property and smart contracts raise this question clearly. If law and governance is just a technology, then perhaps it could be open to disruptive innovation. What we are developing at SCI is the idea of using small zones to pilot comprehensive reforms in the legal, political, and economic systems of nations.
Instead of trying to fix the whole country, just make several small, competing zones with different institutions and let people vote with their feet. Some may fail and others may be spectacular successes, just like in any other startup environment.
The startup municipalities that work can grow by attracting money, talent, and capital. Nations can then bring good reforms to the national level. This is a low-cost, low-risk way to bring major improvements to the developing world. It does not force anything on anyone, and respects human rights each step of the way. Startup Cities has a unique entrepreneurial approach to public policy that is being pursued by other independent groups including Blueseed and the Urbanization Project e.
At least in principle, municipal governments could be held as something like a DAO. Citizens could actually become shareholders in their local government. Citizens could make political decisions through transparent digital processes and interfaces set up around a DAO. While it remains to be seen whether or not a DAO could provide such functionality, multisignature addresses and oracle based wallets, or Hierarchical Deterministic Multi-signature HDM wallets, such as CryptoCorp already exist, providing small organizations the ability to perform some of these functions such as securely voting and releasing funds.
No matter how you might have heard or learned about cryptocurrency, there are different ways to obtain your first tokens. You can mine them, you can buy them through an exchange e. Unfortunately mining Bitcoin profitably currently requires a significant capital investment in single-use ASIC hardware. While you could use a cloud-based hashing service such as Ghash. In fact, even with an ASIC, most mining systems currently lack power to select or validate bitcoin transactions themselves; you are merely selling a computing service hashing to the mining pools.
Over the past several years, one business model has emerged in the Bitcoin mining industry: Typically what this entails is sending X amount of bitcoin to an ASIC manufacture who will then use that bitcoin to invest, design, build and ultimately ship an ASIC to you.
To maximize inventory, manufacturers create batch orders with wait lists. The farther you are down the list, the longer it takes to receive the machine and hence recoup your initial investment.
While you can try your luck in getting the first batch of a new ASIC prior to its release, you are probably more exposed to risks with fewer potential upsides than downsides. Your capital is tied up in a depreciating asset — a machine that unlike a GPU that can be resold to gamers and 3D designers — has progressively lower resale value and has a singular use that may or may not be delivered on time with unknown hashrate performance deltas.
Or you could be thinking, just like the first people who managed to get an Avalon batch last winter or a new terahash-level CoinTerra machine in January, perhaps you might be lucky enough to get placed high on the list for the upcoming KnC Neptune; but the odds are you will not, especially if you are reading this and have not pre-ordered it.
BFL originally announced a variety of different desktop ASIC machines in July and hundreds of customers subsequently preordered them with bitcoin. Yet the group of people that typically fared the worst financially was the miners themselves, as they were nearly all exposed to various types of risks upfront capital costs, land title lawsuits, inclement weather, sickness, landslides and cave-ins and as a consequence, most ended up bankrupt.
Scrypt is a different proof-of-work Bitcoin uses SHAd and requires a larger memory pool to utilize which in turn makes it more resistant to the rapid performance increases spurred by ASIC development.
Chapter 2 briefly discussed a milestone in the Bitcoin ecosystem, the exchange of ten thousand bitcoins for a pizza in Since then, the merchant ecosystem has grown to encompass an estimated 50, online vendors. BitPay is one of the largest startups in this segment, providing an electronic payment processing system with bitcoins for online merchants.
On a nearly daily basis other vendors and merchants independently add bitcoin payments as well. Zynga, the developer behind social games such as Farmville, announced on January 4, , that it would begin accepting bitcoin as payment via BitPay. In chapter 3 I introduced, Jon Holmquist who works with Ripple as the Community Liaison, he is also the founder of Bitcoin Black Friday BBF , the largest e-commerce day for Bitcoin-related purchases, which takes place the day after Thanksgiving filtered through one site.
I also noticed a lot of merchants individually conducting sales promotion campaigns and thought a central launching pad would be a great experiment to show a real empirical case-study of Bitcoin ecommerce in action.
Holmquist built and the consumers came. In , the first year BBF worked with 60 merchants, in and they hope to work with 6, this year. BitPay alone processed 6, bitcoin-based transactions on November 29 th last year up from 99 transactions on the same day the year before. And this is also an area where entrepreneurs and developers can continue to simplify the process for merchants wanting to support cryptocurrencies by providing turnkey services such as plugins.
Perhaps this specific incarnation of virtual money bitcoin is a fad and merchants will drop all support for it.
If that is the case, switching to another ledger would be relatively simple, as both the front end and back end of existing merchant systems could use other altcoins or altprotocols. Yet these case-studies referenced above serve as empirical examples of how value can be transferred globally, to anyone, safely, reliably and nearly instantaneously without any middlemen or institutions. One key theme that all the investors and software architects that I spoke with has been that the ecosystem is in continuous need of competent, creative programmers.
And because the space is so new, so fast and quickly evolving, the barriers to entry are very low. Thus novice coders with business acumen could potentially find entrepreneurial opportunities in the ever-growing ecosystem. It has done this by fusing a global P2P payment protocol with a credit score system, matching loaned bitcoins to borrowers. Pitta is originally from Brazil and previously worked with statistical models for the credit card division of Citi. In contrast, by using an open registration, where a user can submit any pertinent details they want, we have built a statistical engine that can sort through the quality of their data and provide an increasingly accurate rating.
Bitcoin is a perfect microlending platform in that its 8 decimalization units provide flexibility for fractionalization and the transmission is both secure and relatively fast. In contrast, with fiat, merchants and lenders not only risk fraudulent chargebacks but expensive fixed costs irrespective of amount lent e. With bitcoin, there is no way for someone to game the system with chargebacks — once the token is sent, it is sent — transactions are irreversible.
Pitta thinks there are other opportunities in this segment for entrepreneurs who want to help enable the unbanked and underbanked.
In fact, he has found that borrowers are very motivated to obtain a credit line and as a consequence learn and educate themselves as to what Bitcoin and cryptocurrencies are in order to use them.
Yet there are still challenges as well: The protocol enables developers to build an infrastructure on top to create mobile web apps that natively accept micropayments. With this experience Dietz subsequently sees smart contracts and DAOs as having a big impact in the future. Contracts are ultimately just code and are the new innovations and apps to this space. In fact, I think a variety of smart contracts will be available for use by the end of the year — easy to use smart contracts with escrow and verification ability.
Of course, they will have to build the platform first. Cryptoledgers and multisignature functions provide the auditing and logistical abilities. This is a transparent, straightforward method and is quantifiably better than other crowdfunding techniques. For instance, because of the way the current system is designed, there is no way to engage and reward userbases directly, especially early adopters who contribute content.
In the case of Twitter, those who tweeted and convinced their friends and families to use it were not rewarded — rather only the equity holders the founders and investors were able to receive compensation. In contrast, crowdequity can engage and incentivize adoption creating an early userbase with rewards for content and marketing. And the easiest, most transparent method to finance crowdequity is with cryptocurrencies managed by a DAO.
BankToTheFuture is one the first crowdequity platforms in this space and has 10 startups working on Bitcoin-related projects. Adam Levine has been working on a project involving Kickstarter coins that provides similar crowdequity functionality rewarding early adopters and users for their support. Even after a company has exhausted their potential ideas and abandoned such a coin, the very fact that it is so inexpensive could be its resurrection. The core idea is that individuals backers can invest in specific people before launching his or her own venture, campaign or career is launched.
So for example, entertainers, entrepreneurs and artists can directly raise money through coin issuance to backers e. In fact, anyone with an account can issue their own customizable cryptocurrency, offering it to anyone else who has downloaded a Chromawallet the same wallet used for tracking Colored Coins.
Simultaneously, these tokens can be traded on an exchange, producing real-time signals to investors and backers as to the relative strength and health of a particular talent. In terms of credit scores, Nick Szabo has previously described several use-cases for leases and creditor liens whereby after a set of conditions is met or not met ; control is reverted back to the original owner.
That is to say, for credit score purposes e. Thus, in practice Bob may actually have a publicly traded account that he publicly lists on business cards, websites but then he may have several other digital wallets in which he actually stores all transactions, savings and revenue.
Ease of use and simplification was another common theme that investors and developers reiterated. While those with enough technical acumen and computer savvy have become early adopters to cryptocurrencies, the vast majority of the population has difficulties in fully understanding not only how the virtual tokens work but also how to use, secure and store them.
In particular, Percival is interested in taking away complexity — moving the technical processes into the background making them invisible to users. Because he works hands-on with developers on how to make UX and UI flow easier for consumers, he sees numerous opportunities for businesses to simplify processes such as the sign-up process for a particular service e.
While neither he nor most of the investors I spoke with are interested in fiat-token exchanges, he is increasingly interested in business solutions to concepts like proof-of-existence i.
New ideas like proof-of-storage motivates everyone to rush to the door, but only a few can get in and accelerate to consumer adoption. You cannot force trust and coolness, once you lose it, it is almost impossible to get back. I spoke with Dan Roseman who is the founder of Coinality, a job board where employers and job seekers can connect for job opportunities that pay in cryptocurrencies. I created the platform in September because I saw an unmet need in the community that other job boards did not have; receiving bitcoin as compensation.
Since launching the platform, there are now over 1, registered members, with over 1, job applications received from job-seekers, and roughly job submissions openings. Our team also works to find other openings on a variety of other job boards and make sure they are opened on Coinality as well. As a consequence I have first-hand experience and direct knowledge of the kind of jobs that businesses and entrepreneurs are looking for.
There is also a lot of demand for graphic design logos and website layout as well as marketing experts to help drive traffic to a site. Thus if you have those skillsets you will likely be able to find a job in this quickly evolving marketplace.
Roseman pointed out why employers would want to find programmers listed on Coinality. On February 10, , Mt. Gox announced that there was a bug affecting its wallet-system which could potentially enable attackers to double-spend.
Gox was one of the largest fiat-exchanges and its announcement caused volatility in the marketplace. Gox was originally created to handle the trading of a collectible card game called Magic: The Gathering and while the site served its original purpose, as it moved into the cryptocurrency arena its developers were unfamiliar with the needed security toolset to protect against this vulnerability.
I spoke with Kyle Torpey, editor in chief at Cryptocoinsnews and member of the Bitcloud development team. We have since switched frameworks and will now be an escrow service for bitcoin transactions. That is to say, Bitcloud will be 3 rd party, an escrow service for sharing storage space.
The way this will be done is through multisig transaction where you have multiple parties Bob the storage provider, Alice the storage user and Bitcloud is the 3 rd participant, the mediator in multisig transactions. As discussed in Chapter 4, multisignature transactions involve two or more parties who must submit their digital keys to a certain address within a certain time frame for an action e.
I should note though that WeTube is a working title. We need to build Bitcloud first, so what we call WeTube will probably look completely different than what we have right now. The new funding model will work through a concept called Cloudshares, where with each bitcoin transaction a user would get a share in the entire Bitcloud decentralized app an open API. Again, while the original idea was to use Cloudshares to monetize the entire Bitcloud network, we have decided to move the monetization process to the decentralized applications on top of Bitcloud.
So the shares that someone receives for hosting content for WeTube would be shares of WeTube, not shares of Bitcloud. For instance, if Bob purchased storage space from Alice he would use bitcoins as the intermediary token. Another way to think of is, Cloudshares is like a share in decentralized app which continuously builds the entire network.
In our view it is not a good idea to monetize the underlying protocol, because if you had shares in protocol layer then you would have to have dividends. Or in other words, one cannot invest in Bitcloud, only in the decentralized applications built on top of it.
Thus Bitcloud is a free protocol, and we are not monetizing that aspect of it. Because that would mean the transactions between those hosting would be more expensive. Now, instead, we are putting the shares into the layer above Bitcloud, which will be divided by specific applications — including possibly a Facebook-like social networking service. As a consequence, apps themselves are not centralized in one system but rather will interact with a protocol, Bitcloud.
In February I spoke with Nikos Bentenitis. Bentenitis is the co-founder of CoinSimple, vice-chair of the education committee of the Bitcoin Foundation and also creator of the MasterProtocolEducation.
We have done the development for you and added customer analytics in a simple user interface. For instance, a solar energy park can be funded with the issuance of a user-defined cryptocurrency that guarantees the delivery of a certain amount of electrical power after the park is operational. But for the rest of the world, simple payments, the ones already supported by the Bitcoin protocol, when introduced in existing devices cellphones, bank cards would be the killer app.
I am certainly playing catch-up every day. Educational and research groups in the space, like the ones I am working towards with the University of Texas, the University of Nicosia and the University of Hong Kong might provide a way for investors and entrepreneurs to identify business opportunities faster. Bentenitis raises an interesting point regarding educational opportunities in this segment. Perhaps your firm can create a certification process for cryptocurrency or smart contract design competency.
As noted earlier in this chapter, BitPay is a large merchant payment processor and it recently released an open-source fork of bitcoinJS called bitcore. By using a virtual machine through JavaScript and node. We now have 6 people working on it full-time and the goal there is not necessarily to create a specific app but to create a library for the entire community to build from.
Insight 57 is a good project to that illustrates how it has real functionality and provides real value to end-users. If you look at the direction that cryptography and cryptographic accounting are heading, it will just be a matter of time before something like Bitcoin is adopted industry-wide, it just makes sense.
For instance, there is a need for secure international payment systems, especially for Africa and South America and Bitcoin provides this today. Thus, unless these teams make substantial progress on all fronts, they may be taking on too many things at one time. Betamax was a proprietary recording tape standard created by Sony that competed with VHS, a similar yet license-free technology developed by JVC.
This alone will make wallets more secure, easier to manage and ultimately user-friendly because right now for the average person it is virtually impossible to secure a wallet. As a consequence, I think companies such as Apple and Microsoft will end up integrating wallets built into their browsers because of the current support for nodeJS and V8 within existing browsers such as Chrome.
We have also looked at others like Colored Coins and Mastercoin as well, these are all interesting concepts. However, one of the main advantages of having a central server to trade with is that it enables high-frequency trading HFT. In addition, one of the reasons that Kraken currently enables trading pairs with Ripple XRP is that, it is easier and more robust to issue an asset because the network was built for it. While one of the low-hanging fruits of smart contracts is securities trading, it is highly unlikely that a professional trader would use a blockchain directly for an HFT.
For example, in most markets, especially the very liquid ones, where latencies are counted by increasingly smaller segments of time, the pace of 1 block per 10 minutes or even 2. Currently the only way to enable this functionality is via an off-chain solution, such as Kraken, which allows users to build functionality around an internal API.
There will be a lot of opportunity in improving the interoperability between existing digital currency systems, legacy financial systems, and cryptocurrency 2. Merchant integration will also take on a whole new meaning as the industry progresses. A coin based on a silly Internet meme has the third highest trading volume and the fifth highest market capitalization of the entire ecosystem!
Dogecoin is based on the same codebase as Litecoin, yet its developers took a different approach to marketing — basing it solely around an internet meme — and as a consequence, its popularity measured by a variety of metrics network hashrate, daily transactions, reddit followers has surpassed Litecoin. The cryptocurrency layer is being built up nicely, but the social layer is feeble.
For example, we appear to be nowhere near being able to send money to a friend or a merchant over Facebook, let alone all of the other social platforms although PikaPay is doing some interesting things with Bitcoin and Twitter. Eventually, a much higher level of cohesion will be achieved. Although, because we offer sophisticated security options, such as two-factor authentication and master passwords, Kraken is a great place to store digital currency.
Furthermore, I believe Kraken was built from the ground up to be immune to issues like transaction malleability. Our developers have been aware of the issue for a long time. Gox — were impacted by a known bug called transaction malleability. For balance, Coinbase and Blockchain.
As noted above, Kraken operates as an exchange of multiple different cryptocurrencies, including XRP, the token unique to the Ripple network. The biggest one for me has simply been that they actually have a robust product that works. This is why I worked to bolster their community. I knew that Ripple would be successful at achieving some important things the rest of the Bitcoin community was unlikely to easily achieve, such as a distributed exchange e. XRP is fueling the growth of a great company, and Ripple offers liquidity and innovation.
I suspect they will continue to gain support from open source communities and entrepreneurs around the world and eventually do amazing things. In general, altcoins allow for experimentation within the crypto-mining community. Despite the increased media attention, even if these numbers are repeated again this year this may not help boost the performance for some VC funds.
This is not to disparage the VC segment, rather like all industries some VCs are not as nimble at feeling and filtering out business models with revenue generating capabilities as many angel investors are. Increasingly, angel investors today have deep domain experience. With lower costs of starting businesses, this hurdle is largely gone. Having angels with deep operational domain expertise is disruptive to the traditional VC universe. This is not to say that VCs will not flourish once again, however, as it stands, most angels began as entrepreneurs and learned how to generate sales and revenue firsthand.
Furthermore, as noted above, over the past decade technological costs have driven down expenses. For example, relatively cheap cloud services like github and Compute Engine provide services CaaS, SaaS and IaaS that allow many tech start-ups to be leaner than before in terms of what funding they require to cover operating costs. Another way that cryptocurrency-related startups are being funded is crowdfunded IPOs.
And, in addition to crowdfunding sites like Kickstarter and Indiegogo, there are also sites that allow individuals to receive Bitcoin funding directly for their ideas, such as BitcoinStarter and CoinFunder. Consequently, it is premature to write off VCs or claim that angels are the only source to pool funds from.
In fact, a substantial amount of series funding over the course of the last two years in the Bitcoin realm has been from VC firms. So every established business that wants to take advantage of it, including people like Western Union, can do so. While it is too early to predict how these investments will exit, VCs are still a potent market force. In addition to the findings of CB Insights above, below are four charts reprinted with permission from Garrick Hileman which were originally published on February 24, As Chart 1 or rather Table 1 notes, this is the total of the known venture capital funded Bitcoin-related companies globally since Chart 2 illustrates the division of what specific segments those companies are categorized under.
The unknown segment is for undisclosed projects that received VC funding. Chart 3 illustrates that as a percentage of the total VC funds, what geographical location they are located. While these numbers will likely continue to increase over the next year, it is unclear if the geographical trends will continue.
