Investing for the future: How to build your crypto exposure

As the crypto industry emerges from a turbulent period, we find ourselves in a much healthier market for the investor looking to build long crypto exposure. In this report we look at how investors can effectively do so, unpacking the features of nearly 1,000 investment vehicles that provide long exposure to the asset class. We look at ownership models, capturing staking yields, the assessment of product costs and key security considerations in today’s diverse product market. Whether you are looking to invest in Bitcoin, Ethereum or a diversified portfolio of tokens, employ an active or passive approach, we look into the essential criteria to consider.

## Market backdrop and crypto highlights of 2023

The global economy and heightened geopolitical uncertainty continue to present a very challenging macro backdrop. While headline numbers have been remarkably strong, there are real seismic movements under the surface that render the economic structure less stable. The U.S. economy grew 4.9% q/q annualized in 3Q (8.5% nominal) while the Fed hiked rates to the highest levels in a decade to 5.25%. The Federal Reserve has consistently aimed to strike a balance between managing inflation and fostering economic growth. However, at this point, they are juggling multiple complex challenges with diminished control and limited flexibility.

Additionally, as recently as Friday November 10th, Moody’s lowered its ratings outlook on the United States’ government to negative from stable, pointing to rising risks to the nation’s fiscal strength, citing: “the U.S.’ fiscal deficits will remain very large, significantly weakening debt affordability.” 

Despite this difficult macro backdrop, crypto assets have shown strong performance this year (most notably Bitcoin, +129% YTD and +40% QTD as of Nov 15th). This is, in our opinion, driven by a combination of factors, including:

- A regained interest in Bitcoin as a safe haven in the midst of a possible looming sovereign debt crisis. Correlations between crypto and other risk assets have decreased significantly. For example, since peaking ~80% in Sept ‘22, the correlation between BTC and the S&P 500 has remained under 40% all year (in line with the longer-term average) and turned meaningfully negative this quarter (see chart below).

- The vote of confidence provided by some of the largest asset managers globally, including Blackrock, Fidelity, and Invesco (and their senior executives), as they prepare to launch their much-anticipated Bitcoin spot ETFs. This is expected to open the way for renewed and substantial inflows of institutional capital to the asset class.

- Very light investor positioning in the asset class, as both institutional and broader retail investors have essentially ignored the space since the FTX debacle one year ago

These drivers are leading to a revival of activity in the space. We have seen not only prices soar, but also trading volumes finally rebound after having spent Q2 and Q3 at very depressed levels (70% below 2021). Combined with the next Bitcoin halving expected in April 2024 and tangible developments at the technology and application levels (that we discuss below), the asset class seems primed for a sustained increase in trading volumes and strong price trends. 

Importantly, the industry is better prepared for the potential next wave of institutional capital inflows, as the ecosystem continues to learn and strengthen following the FTX debacle. For example, we are finally seeing real momentum towards broader adoption of off-exchange settlement. Many exchanges, including some of the largest like OKX, have secured agreements with various custodians such as Copper, as well as custodians with strong institutional backing such as Komainu (with Nomura) and Zodia (with Standard Chartered). These are key developments that allow for the separation between counterparties of trading on exchange while keeping collateral with the regulated custodian. There is still room for improvement, and not all exchanges are yet set up with such models, but this evolution is key to increasing trust within the industry. Furthermore, it appears that behind the scenes many of the U.S. and global banks are building more familiar TradFi capabilities for digital assets, to be ready once the regulatory framework is more settled.

Regulation has perhaps the most critical role to play in increasing trust in the system. The events of 2022 have certainly given regulators globally a greater sense of urgency. Jurisdictions with clearer regulatory frameworks for digital assets and the underlying technologies (e.g., Switzerland, the UK, the UAE, Hong Kong, and Singapore) have fostered innovation and continue to benefit from an influx of technical and entrepreneurial talent. Meanwhile, the approach from U.S. regulators continues to frustrate, centering more on enforcement than constructive dialogue, and has motivated many companies to look overseas for clearer guidance.

## Continued adoption, innovation and applications of the underlying technology

New technologies often face periods of immense hype followed by disillusionment. The internet, machine learning, and AI were all too often referred to as “a solution looking for a problem”. Blockchain is no different. Despite these cycles, what has remained consistent is the steady technical development, proven real-world use cases, and resounding user adoption in an increasingly mature and consolidated ecosystem. Every transformative technology took many years (if not decades) of foundational work and development before broad public uptake. It's a consistent pattern of steady groundwork followed by rapid, explosive growth and acceptance, the precise timing of which is hard to predict.

We have observed significant developments at the infrastructure level of blockchain in several key areas. These include scalability improvements to increase the throughput of the underlying blockchains, selective privacy enabled by zero-knowledge cryptography that would prevent sensitive transactions from being visible in the public domain, and UX improvements enabled by account abstraction. Ethereum scaling solutions (Layer 2s) dramatically increase the transaction throughput of the network and enable new use cases and applications to be built for a fraction of the cost. These solutions have experienced significant adoption and growth over the past year with transaction volumes up almost 3-fold (from an average of 16 transactions per second (“TPS”) to 53 TPS) and Total Value Locked (“TVL”) up 140% ($5 billion to $12 billion) vs November 2022.

It is also evident that decentralized exchanges and stablecoins have found product-market fit, with an ever-growing universe of tokenized assets being issued and traded on-chain and traditional financial institutions using the code developed by DeFi protocols. This year has seen several large corporations actively integrate blockchain technology into their processes. A primary focus has been on developing payment or settlement layers, leveraging the efficiency and strong finality guarantees of blockchain technology. To illustrate:

- JP Morgan processes millions of dollars in repo transactions daily on the Ethereum network

- Similarly, both PayPal and Visa are establishing payment networks using the Ethereum and Solana blockchains to accelerate, facilitate, and reduce the cost of payment processing

- Earlier this year, Franklin Templeton brought to market the first U.S-registered mutual fund to use a public blockchain to process transactions and record share ownership and has subsequently expanded to other public blockchains.

Real-world applications of blockchain technology such as these lay the groundwork for future growth in on-chain transactions.

Tokenization and payment infrastructure are just two of the very first large-scale applications of blockchain, and it is worth looking ahead and beyond financial applications. One area where we see blockchain technology having significant impact is at the intersection with artificial intelligence. AI, with its powerful capabilities and transformative potential, is often met with criticisms over the transparency and integrity of its processes and data inputs. Blockchains, valued for their immutability and transparent ledger system, offer a potential solution to these challenges. The synergies between these seemingly unrelated technologies not only enhances the reliability and accountability of AI systems, but also opens up new avenues for innovation, where decisions made by AI are verifiable and data sources are credible, leading to more robust, ethical, and efficient solutions.

As we reach the 2 year anniversary of peak euphoria and prices in crypto markets and 1 year since the fall of FTX, momentum in the crypto space seems to slowly be turning as the industry has learnt important lessons, made important adjustments and carries on driven by the ongoing innovation. The recent news about Binance looking to clean the slate and move forward under tighter supervision from the DOJ is another encouraging sign of a maturing ecosystem where to survive, all players need to adapt and institutionalize. We are encouraged by all these signs and the prospects they represent for the broader asset class.

## How Digital Asset Funds custody their assets

To better address the notion of counterparty risk within the crypto fund space, it is vital to understand how funds store their assets. Below we set out the most common options used by market participants to address the question of custody. Crypto funds typically will opt for one or a combination of these solutions.

**Centralised Exchanges:** Research shows that there are currently more than 500 crypto exchanges worldwide (according to [CoinGecko](https://www.coingecko.com/en/exchanges)). These entities play a central role within the institutional crypto ecosystem, with some of the more notable players including Binance, Coinbase, Kraken, Huobi and up until recently, FTX. Although the CME and NYSE offer futures trading in ETH and BTC via Bakkt, almost all the liquidity is on crypto native exchanges.  The graph below shows the relative dominance of centralised exchanges (CEX) to overall spot trading volume when compared to decentralised platforms (DEX). Even though DEX has increased their share of total volumes since the middle of 2020, CEX still accounts for over 80% of trade volumes.

Exchanges allow clients to hold their digital assets directly with the exchange itself and these are generally held in a commingled pool with the assets of the exchange’s other clients. Clients of an exchange deposit their assets in the full trust of the exchange, which in turn has complete control over those assets. While this handover of control is also present in TradFi, the lack of transparency and unclear regulatory status of exchanges is a significant risk, as we outline further below.

Amongst the initial investor concerns towards exchanges is that they were easy targets for hackers. Indeed, the perception was that crypto exchanges keep all client assets (and related private keys) online. In reality, our research of larger exchange entities shows that they maintain c.5-10% of assets online (i.e. in hot storage wallets) to meet customers’ ongoing trading requirements with the remaining 90-95% stored in cold-storage (albeit in a commingled fashion). This allows exchanges to hold the majority of client assets offline, thereby preventing bad actors from deploying traditional online hacking methods. These large pools of assets nevertheless will always remain an attractive target for an ambitious hacker.

To further mitigate counterparty risk, well run exchanges have established sizable insurance funds to cover unforeseen events such as potential hacks (particularly of assets in hot wallets), as well as to limit the exchange’s counterparty liquidations during times of extreme volatility. These funds have been built up over time as exchanges allocate a portion of their trading commission income to them. One of the better known examples is Binance’s “SAFU” (Secure Asset Fund for Users) fund which has recently increased to $1Bln. It is important to note that the level of transparency and the types of events / losses that qualify to be covered by these funds varies by exchange. 

While the lack of transparency from exchanges in key areas of due diligence remains, as highlighted by the recent news surrounding auditing firm Mazar halting all of its crypto client work, some of the larger exchanges have begun to make progress in this area.

**Decentralised Exchanges:** An increasing number of crypto funds have strategies that require assets to be deposited into the smart contracts of decentralised protocols, e.g., Uniswap. Whilst in this scenario funds are not exposed to a centralised party (i.e., a counterparty with unilateral control of the deposited funds), smart contracts do carry their own unique sets of risks. This includes the risk of programming errors, where erroneous code can open a decentralised protocol to the risk of asset theft. Poly Network is a good illustration of a vulnerability exploitation where c. $611m was stolen in February 2022, although the hacker subsequently returned the stolen funds. Fortunately, the crypto ecosystem has benefited from the emergence of specialised smart contract auditing firms, such as Quantstamp or Chainsecurity, which have developed robust due diligence practices to assess the security of such smart contracts. Most of the major protocols have benefited from significant due diligence and have often passed the test of time. Newer, emerging protocols are, by definition, riskier than their more established counterparts.

**Custodians:** The landscape of crypto native digital asset custodians has significantly expanded over the past few years, with a number of established players now offering crypto custody solutions. These include Coinbase, Copper, BitGo, Anchorage and BitPanda to name but a few. The lucrative crypto custody market has also attracted the interest of large traditional financial institutions with participants such as Fidelity, BNY Mellon, Nomura and Standard Chartered now offering custodial solutions, albeit some of these support only a limited number of crypto tokens at present. Others, such as Sygnum and SEBA, have relevant banking licences in chosen jurisdictions.

Custodial infrastructure and services can differ among custodians, but generally, customers' assets are segregated from each other. Assets in such segregated wallets are visible on-chain to anyone with the associated public key or wallet address.  Controls over the withdrawal of these assets further enhance their security. We summarise some of these controls further down in this piece.
Custodians may also hold commingled wallets in some form to enable a faster trading turnaround for clients, particularly where withdrawal protocols impose a long lead time. 

Some custody infrastructure allows for safeguarding of assets by not permitting transfers outside a network of pre-approved trading venues, colloquially referred to as a ‘walled-garden’ within the crypto ecosystem. Funds will have trading agreements with respective crypto exchanges, and therefore on its own, a ‘walled-garden’ does not protect crypto funds against exchange counterparty risk.
It is critical for a crypto fund manager (as well as investors carrying out due diligence on the manager) to understand the exact custodial arrangements in place. 

Another solution rapidly gaining traction is that of off-exchange settlement. Examples include Copper’s ClearLoop, Binance Custody mirroring, or Coinbase Prime off-exchange settlement. Under these arrangements, crypto funds delegate assets to be traded to relevant exchanges in some form, but the assets do not leave the custodian’s cold storage platform until settlement, thereby reducing exposure to exchanges’ counterparty risk. Typically, absent such off-exchange settlement arrangements, trading directly on crypto exchanges requires pre-funding. These solutions come at a cost, which should be weighed against the exchange counterparty risk being mitigated. Although the technology has proven sound, a limiting factor has been the unwillingness of some crypto exchanges to work closely with these platforms. This means that the list of exchanges where funds can benefit from off-exchange settlement has so far been limited. 

Following the events of 2022, and notably the FTX implosion, this trend has reversed as exchanges are actively partnering with service providers to offer off-exchange settlement.

**Self-Custody:** It is possible for funds, or indeed any user, to store their own private keys to digital assets, with various service providers offering wallet-as-a-service custodial solutions. Examples include Ledger, Trust Wallet and Trezor, among others. Although the technology is viable, self-custody is a new concept for institutional allocators, and is often viewed as a red flag given the perceived risk of the fund’s assets being moved or withdrawn directly by staff or insiders. In the case of many early stage tokens, these are often not supported by custodial platforms or exchanges, and self-custody is therefore the only option for funds wanting to hold these tokens. It is therefore critically important that proper processes are put in place to manage private keys, such as use of multi-signature wallets. Equally, seed phrases that facilitate regaining control of assets in the event of a compromise of private keys require secure storage.

In the majority of cases, crypto funds custody assets either with custodians or on exchanges (including on smart contracts of decentralised exchanges for funds with DeFi strategies), with a limited number employing pure self-custody.

## Crypto Fund Custody Requirements

In addition to security considerations, the choice of where a crypto fund custodies its assets is largely driven by the requirements of the fund’s strategy. For example, more active investment strategies will pay particular attention to the time required to move assets from their custodian to a trading venue, such as a centralised exchange. This will depend on the technological infrastructure deployed by the custodian to store private keys.  Some transfer protocols can take up to 24 hours to process a withdrawal, whereas with other technical solutions, such as multi-party computation (“MPC”), customers can withdraw assets within minutes. On the other hand, a long-only crypto fund with a low trading frequency has a much wider choice of custodial solutions. 

Other strategies require a fund’s assets to be held as collateral on trading venues (centralised exchanges or decentralised protocols). Such funds will then be exposed to the counterparty risk of the respective exchange. 

## Counterparty Risk Management Best Practices

As we have highlighted previously, exchange counterparty risk remains a primary concern within the institutional ecosystem. To address this, crypto market participants can borrow from the TradFi space and apply battle-tested best practices. These include: 
- Diversification by holding assets on several exchanges with strict limits of exposure to each exchange on a risk assessment basis. Ongoing monitoring of the credit health of the exchanges that a fund is exposed to is also key.
- Strong real time risk management is essential. This requires a strong technological stack and development teams. As a result, sophisticated players closely monitor an exchange’s credit health by reviewing news flow as well as live-tracking an exchange’s on-chain transaction data for signs of abnormal activity or large capital outflows, taking remedial action as appropriate. In the recent case of FTX, this monitoring often made the difference between crypto funds that were able to remove assets from the exchange prior to the suspension of withdrawals, and those that were not. 
- Sweeping any assets not required for immediate trading to a custodian(s).
- Maintaining excess fiat collateral with credible financial institutions, which can be held in the form of money market funds or Treasuries (for example), to the extent possible; subject to maintaining operational buffers at the custodians and/or exchanges.
- Making use of off-exchange settlement of crypto assets or similar arrangements offered by some custodians (as outlined above).

Whilst storing assets with a custodian reduces exchange counterparty risk, a fund will however be exposed to the credit risk of the custodian as a counterparty. There are several factors that allow participants to gain additional comfort when facing custodian counterparty risk: 
- Custodians are more heavily regulated than exchanges, with fiduciary responsibilities associated with the custody of client assets. Anchorage for example has a bank charter in South Dakota, USA and Coinbase Custody is a qualified custodian under the New York Banking Law. From our research on larger exchanges, regulations are generally limited to the requirement to carry out AML and KYC checks on customers. Moreover, some offshore exchanges are not even subject to such licensing requirements.
- Custodians are generally more transparent during the due diligence process compared to exchanges. Custodians are more willing to disclose key information on their governance, financial condition, infrastructure setup and third-party audits of such, e.g., reports on internal controls, audited financial statements, summary results of penetration testing, amongst others.
- The segregation of wallets at custodians, as well as controls observed at the custodians over the withdrawal of assets, provide a significant level of comfort. Withdrawal of assets requires the involvement of the asset holder, thereby reducing the risk of asset misappropriation. The ability to make asset transfers only to pre-approved addresses (and stringent controls over adding to such addresses) further enhances the security of assets.  
- The custodians we have researched also have insurance coverage in place, e.g., Copper recently announced its insurance policy with Aon for a USD500m coverage. The coverage differs by custodian, but our general observation is that aggregate insured amounts are significantly lower than total assets under custody (c. <1% of AUC in some cases).
- It is also important to note that custodian’s balance sheets (including insurance coverage) are only a small fraction of assets under custody. This is not unusual for standalone custodians (even in TradFi) and they are therefore unlikely to refund all clients for losses under the extreme scenario of a total loss of client assets. That said, we do however estimate the probability of total loss of assets at a reputable custodian to be low based on the robustness of their infrastructure setup.

What remains to be tested however is how a custodian bankruptcy scenario would play out in practice; and how long it would take clients to access their assets. Custodians that utilise MPC technology to manage private keys (e.g., Copper) distribute digital asset key shards between a client (a fund), the custodian and a trusted third party entity that is pre-approved by the custodian. In theory, if the custodian were unavailable for any reason (including bankruptcy), a fund and the trusted third party could use their two shards to move assets from the custodian. On the other hand, custodians that hold digital asset keys predominantly in hardware security modules (“HSMs”) (e.g., Coinbase) generally store all the shards of a private key; and a custodian’s employees are always involved in the withdrawal process. These custodians have failover systems in place that would enable clients to access their assets in particular scenarios. However, until such an event has taken place it is difficult to know for sure how this process would unfold. For this reason, it is prudent to have more than one custodial arrangement in place.

## The Role of Crypto Prime Brokerage

The concept of prime brokerage within the crypto space is still in its early stage, although developing rapidly, and in many ways will differ from the version familiar to TradFi professionals. That said, a number of new crypto prime brokers such as Hidden Road, FalconX, BeQuant and Floating Point have emerged, offering a range of solutions to optimise leverage, execution and trading fees. A number of these prime brokers offer an alternative to exchange counterparty risk by opening sub accounts for their clients on exchanges in the prime broker’s own name. The client then faces the prime broker directly and has the option to insure their assets. Unfortunately, the players currently involved in this segment are still small, with smaller balance sheets and no access to central bank liquidity, a critical difference to their TradFi counterparts. However, following the collapse of FTX, crypto exchanges appear to be cooperating with crypto prime brokerage firms in the latter's efforts to minimise exchange counterparty risk. We therefore expect a growing importance of the prime broker community in the crypto ecosystem. 

## Looking Ahead

Thorough due diligence of crypto exchanges is required because of their significance to the crypto ecosystem. That due diligence requires constant updating during a crypto fund’s lifecycle. The challenge so far has been the level of transparency from crypto exchanges, as outlined above. 

How can another FTX be avoided and how can market participants further mitigate counterparty risk? This is a much broader question that goes beyond just performing thorough due diligence on exchanges and the associated risks facing a centralised entity.

**Enhanced transparency from exchanges:** In an effort to increase transparency and keep up with institutional requirements, larger exchanges have been proactively providing additional due diligence information to market counterparts and regulators. The FTX event has accelerated this trend as various exchanges have now begun to publish their proof of reserves. Although these are positive initial steps, we expect additional efforts in this direction to be made. 

Whilst not fool-proof, transparency on an exchange’s liabilities (customer claims) will be helpful in order to assess its solvency. Gaining assurances that clients’ assets are segregated from an exchange’s own assets is also critical. Working closely with independent auditors to produce reports on internal controls, including proof of solvency, would go a long way in providing additional comfort to participants in the crypto ecosystem. 

**Increased regulation:** In the short term, we expect increased regulation of exchanges to enforce additional risk management guidelines. In fact, regulation already exists, particularly in Japan where, after the events of Mt.Gox and Coincheck in 2018, Japanese exchange operators are required to segregate customer accounts and maintain 95% of customer assets in cold storage. We expect other regulators worldwide to implement enhanced regulatory obligations on exchange operators and other participants in the crypto ecosystem generally.

**Separation of execution from custody:** Longer term, we would favour the separation of execution from custody, much like the process observed in TradFi. With this in mind, many exchanges should move towards becoming non-custodial over time.  This can be achieved through tri-party arrangements whereby collateral is held by a third party custodian in escrow, thereby limiting the counterparty risk of exchanges. Again, this is something we observe in TradFi. In fact, some crypto prime brokerage players are already working on similar arrangements.

**Consolidation of exchanges:** There is also likely to be consolidation of exchanges and an emergence of a smaller number of players with larger balance sheets. Concurrently, there is likely to be continued growth in the importance of crypto prime brokerage, with closer links to crypto custodians, which could be vertically integrated. Ironically, this is no different to what we observe in TradFi today.

**DeFi and Self-custody:** While DeFi and self-custody also conceptually solve for counterparty risk, more stringent application of KYC rules is needed to attract the interest of the institutional community. Certain platforms such as AAVE are making progress on this front and there is also innovation taking place in on-chain KYC solutions.

## Conclusion

FTX’s collapse is a real wake-up call for the crypto industry and serious efforts are already being made to ensure that the impact of a similar event in the future would not have the same systemic impact. As we have highlighted above, solutions already exist to significantly mitigate counterparty risk, but FTX has provided the impetus for these to become more widely adopted. Such solutions include off-exchange settlement, albeit with wider participation from the crypto exchange community.



If there has been one key takeaway from the eventful past few months in the crypto space, it is the importance of managing exchange counterparty risk. Here we take a closer look at how digital asset funds custody their assets and explore the best practices that have been deployed to address exchange counterparty risk.

Ethereum’s recent change in consensus algorithm to Proof of Stake has introduced a new class of exctractable value: MEV over multiple consecutive blocks, also known as Multiblock MEV. This has the potential to heighten the negative externalities of MEV. Herein we detail a numerical solution to the cumulative distribution function for the length of the longest $k$-blocktuple for a validator pool in a given epoch and compare our findings with observed events.

## The Evolution of Trust

A primitive example of this trade-off can be found in the earliest forms of banking where, centuries ago, assets were deposited in exchange for promissory notes, allowing merchants to more conveniently exchange value with one another and scale their businesses through credit. As our systems and businesses have increased in complexity, we have had to scale trust to match. It is this interconnected web of trust between us that allows organisations to create value. The relationship between trust and macroeconomic growth is well documented: more trusting environments foster prosperity, trade, employment and economic growth. If trust has gotten us to where we are today, why not carry on as we have done for centuries? 
 
The problem is that trust is eroding at a time when it is arguably more important than ever. Trust today is multi-dimensional insofar as we place it in competent, reputable and regulated entities. These entities have become increasingly centralised and time has shown that these pillars have failed to protect us. Centralised trust points are in fact single points of failure that can be opportunistically exploited, resulting in a world where funds are misappropriated, data misused and speech arbitrarily censored. The reasons behind the erosion of trust are many, but can likely be attributed at least in part, to repeated instances of corporations and institutions abusing this trust such as the Facebook–Cambridge Analytica data scandal. The long term effects that this erosion of trust can have, cannot be understated.
 
What if there was a better way for us to significantly scale trust along a new dimension without the associated downsides? Whilst this may sound too good to be true, that’s exactly what public blockchains are promising to deliver. How? By decentralising control and thereby dis-intermediating trust; where handshakes and gentleman’s agreements are replaced with deterministic open source software that provides strong guarantees. Rather than relying on human trust - through a combination of cryptographic primitives, distributed computing and game-theoretic incentives - public blockchains harness our human tendency to act in our own self-interest to build networks that require no oversight yet produce positive outcomes for the greater good. This does not mean that we need to do away with all other forms of trust or human relationships (e.g. reputation, competence, regulation) but rather this enables more ‘bounded’ forms of it, where people can more deliberately choose whom they place their trust in.

## Parallels with The Internet
 
Understanding these abstract concepts and the value they will unlock can be challenging, so it can help to first look back in time at the internet to understand its core value proposition. After all there are striking similarities in the trajectories both technologies have followed. Both the internet and cryptography were developed by the military, were initially misunderstood and had their potential impact on the world underestimated. This isn’t to say that blockchains are a ‘new internet’ - far from it. Blockchains should be thought of as an additional layer of technology that sits atop the internet, adding new functionalities and enabling new use cases that weren’t previously possible.
 
Before the internet, the ability for information to propagate throughout the world was very limited. The 
value that the free flow of information has brought to our lives can be seen in almost everything we do – even in something as seemingly trivial as sending an email to a friend. Instead of needing to send a letter, telegram or telex message, where charges and delivery times varied depending on the destination, we can now send an email instantly and at practically zero cost. The frictionless exchange of information enabled the world to scale, facilitating international trade and innovation on an unprecedented scale.
 
Returning to the example of sending an email to a friend - regardless of when you send it and where they are in the world, they’ll receive your message and be able to respond to it almost instantaneously. Yet when sending that same friend anything of value e.g. money, when exactly they receive it and how much it will cost you is largely dependent on where they are in the world. In other words, information is borderless, so why isn’t value?
 
This particular example shines a spotlight on the limitations of our current systems and brings us back to the issue of scaling trust. Sending money, particularly across borders can take several days because unlike information, sending anything of value requires trust. This trust is built up over time and is incredibly valuable but also costly to maintain. In spite of this financial institutions are constantly having to monitor transactions for fraud prevention - a time consuming and costly endeavour. Blockchains allow this trust to be ‘outsourced’ to the network, where data records are verified and secured cryptographically.

## Value Proposition
 
What then is the value proposition of this technology? In a nutshell, it is the decentralisation of control - however this is the means to an end. In doing so, we significantly increase our ability to scale trust globally, facilitating open-source development, transparency and composability between pieces of software, where value is treated as a first-class object and novel forms of ownership and coordination are made possible.
 
So what does a world enabled by blockchains look like? Much like in the early days of the internet, it is difficult to imagine all of the possible use cases and innovations that are yet to come. What we can do is look at what is being built today to give us an idea of what the future holds:
 
- **Value will flow freely**. Send anything of value - be it money, a deed to a house or shares in a company - as easily as sending a text message is today. Individuals and businesses will transact globally in a frictionless and efficient manner. True microtransactions will enable new forms of monetisation.
- **Data will be portable**, empowering users to switch platforms effortlessly. In the absence of user lock-in, services would need to compete on features and providing the best experiences for their users rather than relying on their monopoly over data. No longer will we have to trust whether our data is being misused or sold without our permission.
- **New forms of ownership** mean that access to wealth-building assets is democratised. Creators will have ownership in the platforms they provide content for, better aligning incentives. New ways of licensing and distributing intellectual property and proprietary ML models will be made possible. Software will be owned by its users. 
- **Novel forms of privacy** enabled by zero-knowledge proofs with a multitude of applications e.g. cryptographically proving your eligibility for a loan without having to disclose any information to the lender or verifying identity and credentials with a universal single-sign-on.
- **Secure peer-to-peer communications** enable once disparate systems to talk to one another in real time. Intelligent devices such as autonomous vehicles will be able to seamlessly communicate with their local surroundings.
- **Programmable value** will expand the universe of assets. Derivatives, tokenised assets, escrow, credit and insurance are expressed as composable pieces of code.

## Conclusion

As with any nascent technology there are teething problems, challenging hurdles to overcome and new questions to be answered e.g. which trade-offs should we make in the pursuit of scalability? How can privacy enhancing protocols exist within current regulatory frameworks? What is the best way to solve key management for the everyday user? How do we merge existing and frontier systems?

The user experience can be awkward and the learning curve is steep. However, amidst all of this there are working applications and transformative products being built today with glimmers of what is still to come. Assets can be traded on decentralised exchanges such as [Uniswap](https://uniswap.org) or borrowed against on decentralised lending markets like [Aave](https://aave.com), at anytime and from anywhere. Identity is portable and data is composable with data networks such as [Ceramic](https://ceramic.network/how-it-works), messaging is peer-to-peer with decentralised communications networks such as [XMTP](https://xmtp.org/docs/introduction) and training of AI models is distributed with [ASM](https://whitepaper.alteredstatemachine.xyz/how-asm-works/agent-training-gyms). Everything from exchanges and publishing houses to games and marketplaces is owned by their users and contributors. 

For younger generations today, it can be difficult to imagine a world before the internet. Future generations will find it difficult to imagine the world we currently live in - where we were forced to trust blindly, rather than being allowed to choose. Blockchain’s potential to have a positive impact on our world is significant and we believe it is a vision worth working towards.

Trust is foundational to everything we do, yet it is eroding at a time when it is arguably more important than ever. How do blockchains allow us to scale trust and what novel use cases does this enable?
