In the bustling world of blockchain and decentralized applications, QuickNode has established itself as a formidable force. This doc will explore a comprehensive exploration of QuickNode's business model, competitive landscape, potential drawbacks, and key tactics to go head-to-head with this blockchain player.

QuickNode’s Business Model - The Success Recipe​

QuickNode offers an exemplary performance, with its speed being 2.5 times faster than competitors. This speed isn't just a claim; it's backed by actual performance metrics, which you can check out on their comparative page.

With the flexibility to handle 15+ chains and a mind-boggling 99.99% availability - SLA guaranteed no less - QuickNode offers unparalleled reliability in the space. Furthermore, they've successfully onboarded some big guns like Google, Visa, Adidas, and Coinbase. They've also courted long-term internet investors, including 776 Ventures, Tiger Global, Softbank, and more.

The Four Pillars of Revenue​

Node Management

QuickNode's Node Management Platform is the company's flagship product and primary source of revenue. With a dual-tiered model, it offers self-service options for developers and businesses who want hands-on access, as well as enterprise-grade solutions for larger corporations. This approach covers a wide range of customer needs, from small startups to industry juggernauts.

• Self-service Options: This is ideal for developers or small-scale organizations that require on-demand access to blockchain networks. It offers flexibility and control, allowing them to deploy nodes and manage their applications as needed.

• Enterprise-grade Solutions: For larger corporations with more complex needs, QuickNode offers a custom-tailored solution. This package includes advanced analytics, priority support, and guaranteed uptime. The personalized nature of this solution means businesses can focus on building their products rather than worrying about node management.

Icy Tools - NFT Development

Icy Tools, QuickNode's next pillar, offers unique utilities for NFT development. As the NFT market has exploded, the demand for tools to streamline the creation, management, and trading of NFTs has grown exponentially. QuickNode's Icy Tools provide developers with an efficient and intuitive way to tap into this burgeoning market, thereby driving significant revenue for the company.

App Marketplace

QuickNode's App Marketplace is another key revenue stream. It hosts a wide range of applications built on QuickNode's infrastructure, providing a platform for other businesses and developers to sell their products. QuickNode, in turn, earns revenue through commissions and listing fees. This marketplace not only adds a vibrant ecosystem to QuickNode's offering but also acts as a value-added service for their node management customers.

Network Integration Fees

Lastly, QuickNode also derives revenue from Network Integration fees. Given the ever-expanding landscape of blockchain protocols, integrating new networks is a continuous process. QuickNode charges businesses and developers a fee for this service, providing them with seamless access to emerging protocols.

Each of these pillars plays a crucial role in QuickNode's revenue model, leveraging different aspects of the blockchain landscape to ensure the company's sustained financial health. Their diversified income sources have helped them remain resilient and adaptable, ready to face the dynamic challenges of the industry.

High-speed growth of the business​

QuickNode has shown robust growth metrics that underscore its escalating position in the market. In 2022 alone, the firm witnessed a more than 40% quarterly uptick in enterprise revenue, demonstrating a sustained demand for its offerings.

Platform usage, a key indicator of product adoption, scaled 550% times over the past year. Reflecting a strong bottom line, gross revenue also spiked, showcasing a 370% YoY growth.

Further indicating QuickNode's expanding user base, new account registrations jumped by 177% YoY. Additionally, there was a massive 264% YoY surge in endpoints deployment, proving the company's increasing operational scale and efficiency.

The Competitive Landscape - Where the Rubber Meets the Road​

Now, let's delve into the crux of the matter. While QuickNode leads the pack in the node creation/connection market, it’s not without competition. Rivals like Amazon, Microsoft's Azure, and IBM are eyeing the space, posing potential threats to QuickNode's dominance. However, QuickNode has managed to hold its ground, primarily due to its industry-leading speed and flexibility, earning it rave reviews from customers. But is that enough to keep it ahead in this high-stakes game?

The Alchemy Conundrum

Alchemy, with its Silicon Valley roots and robust investor backing, is an intriguing contender. While it brings a lot to the table, it's not quite up to par with QuickNode when it comes to speed and offering. Yet, Alchemy's Silicon Valley connection and buzz could play a role in the ongoing battle of the nodes. It raised at 10.2B valuation on the market top reflected in their valuation and revenue multiple, which is rumored to be 120x - 200x.

Infura - The Fallen Star

Infura entered the arena as a trailblazer, focusing on Ethereum node RPC. However, post-acquisition by ConsenSys, it seems to have lost momentum. Although Infura supports six chains, its speed is trailing behind QuickNode's.

Coinbase Cloud - The Fake Dark Horse

Acquiring Bison Trails puts Coinbase Cloud on the map, but rumors suggest Coinbase is dissatisfied with the outcome and has cut off the business. Although the product relaunched with support for 25 chains, only Ethereum is in general availability. Moreover, its lack of public speed data keeps it shrouded in mystery.

BlockDaemon - A Specialized Contender

BlockDaemon distinguishes itself by specializing in an area - institutional-grade staking - that's rather different from QuickNode's primary focus, and hence it's not seen as developer friendly.

Is QuickNode falling short?​

Not exactly. It's more about the vast ocean of opportunities that its competitors might venture into. It's like saying that no team can win every time, even if they have the best players. This field is big enough for many players to participate, and each player has their unique strategies. Let's not forget - blockchain is about dispersing power, not centralizing it. So, no player can dominate this field.

Furthermore, QuickNode's influence is concentrated on certain blockchains, with a maximum of 25 chains. In the real world, there are at least five to six hundred blockchains, and with the rise of AppChain, more players will enter the market. This will undoubtedly give new entrants new opportunities.

Lastly, QuickNode focuses on large enterprise users, and its pricing has risen accordingly, making it unsuitable for small and medium enterprises and independent developers.

The Team Behind QuickNode - The Brains of the Operation​

The QuickNode team, with its previous experience in managing hosting and CDN scaling businesses, brings a wealth of relevant skill sets to the table. Yet, we can't dismiss the fact that their competitors also come with their unique strengths, networks, and experiences.

BlockEden.xyz vs. QuickNode​

BlockEden.xyz follows the strategies below to effectively compete with QuickNode.

1. Differentiate on Unique Services: First, BlockEden.xyz can offer unique APIs or blockchain services that QuickNode does not provide, like Aptos and its indexer, Sui and its indexer. By identifying gaps in QuickNode's offerings and stepping in to fill those gaps, BlockEden.xyz presents itself as a unique, comprehensive solution.
2. Competitive Pricing: Another way to compete is through pricing. BlockEden.xyz offers more competitive pricing models that are more affordable for smaller businesses or developers. A flexible, scalable pricing model can attract a wider range of customers, from startups to enterprise-level organizations.
3. Superior Customer Service: Providing superior customer service and technical support is another great way to compete. Quick response times, helpful resources, and knowledgeable support staff make all the difference when it comes to customer satisfaction and loyalty.
4. Partnerships and Integrations: BlockEden.xyz seeks partnerships with other blockchain platforms or services, creating integrations that make it more appealing to customers. These partnerships can expand BlockEden's reach and functionality.
5. Community Engagement and Developer Support: QuickNode has a strong developer community. BlockEden.xyz could compete by fostering a similar community and a developer DAO 10x.pub, providing strong support, and cultivating an ecosystem of developers and users who can contribute to and improve the platform.

Our key to successful competition is not necessarily to beat QuickNode at its own game, but to provide unique value that QuickNode does not. We are finding the niche where BlockEden.xyz can excel, and focus on serving that market exceptionally well.

Etherscan stands as the leading Ethereum block explorer and has significantly grown since its inception in 2015, extending its services to include other chains such as Fantom, Polygon, BSC, Arbitrum, among others. While Etherscan has successfully secured funding twice - in 2016 and 2021, the specific amounts were never disclosed. Interestingly, the company didn't take advantage of favorable funding conditions to raise more capital, suggesting they're likely profitable.

Etherscan's main revenue streams come from Software as a Service (SaaS) offerings and advertising. Their range of SaaS solutions includes various on-chain tools like wallet-to-wallet messaging, staking, token approvals, and more.

As per LinkedIn data, Etherscan maintains a workforce of 29 employees. The estimated cost of this staffing level, also referred to as the headcount burn, is approximately $1.2 to $2.15 million each year.

Income Sources​

• (58.4%) SaaS / Total - Estimated Income: $2.91M - $12.55M / yr
  • Explorer as a service
  • API plans
  • BSCscan's delegation services, wallet-to-wallet messaging, token approval-revoke tool, etc.
• (1.4%) Newsletter - Estimated Income: $0.12M - $0.3M / yr
• (40.2%) Website Ads - Estimated Income: $2.4M - $8.64M / yr
• Donations

Headcount and Burn​

Here is the burn rate for headcounts, not including operational costs such as third-party vendors, office spaces, etc.

Item	HC	Pay range	Estimated Expense	%
Engineering	12	$100k - $200k	$1.2M - $2.4M	55.43%
Business Development	8	$80k - $120k	$0.64M - $0.96M	22.17%
Operations	4	$70k - $100k	$0.28M - $0.4M	9.24%
Community and Social Services	3	$60k - $90k	$0.18M - $0.27M	6.24%
Information Technology	2	$100k - $150k	$0.2M - $0.3M	6.93%

It would be relatively easy for Etherscan to expand to businesses like Dune’s dashboard or Nansen’s wallet tagging. However, they are not doing so, which indicates that they might be extremely profitable.

There is a constant buzz in the world of cryptocurrency, with new narratives cropping up at regular intervals. While a lot of attention has been given to Shanghai upgrades, BRC20, meme coins, and halving phenomena, the "DeFi Summer" of 2020, a milestone in the rotation of narratives in the crypto world, has been mostly forgotten. However, three years later, there have been some noteworthy developments in the DeFi space worth highlighting.

The Declining Attention on DeFi​

Post the "DeFi Summer" of 2020, the Decentralized Finance (DeFi) ecosystem has evolved and grown significantly, introducing innovations like decentralized exchanges, lending platforms, derivatives, fixed income tools, algorithmic stablecoins, asset synthetics, and aggregators.

However, after peaking in May 2021, traditional DeFi blue chips like UNI, LINK, SUSHI, and SNX have been seeing a decreasing trend. Leading DeFi projects such as Uniswap and Synthetix and new entries like OHM under "DeFi 2.0" seem to be gradually fading away from the market spotlight. The DeFi narrative, once the darling of the crypto world, has been overshadowed by other emerging narratives like NFTs, DAOs, Metaverse, and Web3.

Fundamentally, the services offered by most DeFi products are similar, with only a few leading products standing out due to their brand and user stickiness. Many platforms rely heavily on their native tokens to incentivize user participation. However, these liquidity rewards can inflate Total Value Locked (TVL) figures temporarily but are not sustainable in the long run, leading to volatility and quick capital movement when new higher yield opportunities arise. This dynamic has led to an overall downtrend in the price of DeFi tokens since 2020.

Innovations in the DeFi Space​

Ignoring the declining performance of DeFi tokens in secondary markets, some interesting changes are happening within the DeFi landscape. Notably, leading projects like Curve and MakerDAO have been diversifying their product range, blurring the boundaries between different DeFi protocols.

MakerDAO, traditionally known for its DAI stablecoin, has started venturing into the lending space with the launch of Spark Protocol. This protocol, built on Aave V3 smart contracts, allows users to borrow assets like ETH, stETH, DAI, and sDAI. This is a remarkable shift in strategy and points towards a significant overlap of stablecoin and lending functionalities.

In a similar vein, Aave, primarily known for its lending services, is planning to launch its native decentralized stablecoin, GHO, backed by collateral and pegged to the dollar. Both MakerDAO and Aave's lending mechanisms are based on Aave V3 smart contracts, and it will be fascinating to see who emerges successful in this foray outside their traditional domains.

Curve, which is known for its large-scale asset exchange services, has also recently introduced its stablecoin, crvUSD. With Curve's inherent liquidity advantages, crvUSD seems to have a headstart in the stablecoin race.

Among all these DeFi blue chips, Frax Finance has made significant strides in liquidity collateralization. Its product frxETH has shown exceptional growth since its launch in October 2022, reaching almost 220,000 tokens valued at around $400 million within just 200 days.

Conclusion​

The sustainability of DeFi projects that relied heavily on liquidity incentives was always questionable. This reality has prompted leading DeFi protocols to innovate and diversify their product ranges, breaching the traditional boundaries that separated them.

Ethereum, the world's most adopted blockchain platform for smart contracts, is known for its regular upgrades, each bringing forth new features, parameter adjustments, or enhanced security. These upgrades, driven by both proactive innovation and the need to mitigate potential security threats, have punctuated Ethereum's evolution over the years.

Before the Ethereum merge last September, the platform had seen 14 upgrades. Notably, a reactive upgrade occurred in 2016 after the DAO Fork incident when Ethereum Classic (ETC) emerged following a cyber-attack that jeopardized the DAO project's ETH funding.

Over the past few years, significant upgrades have taken place. The London upgrade in August 2020 introduced EIP-1599, introducing ETH burning and dynamic adjustment of the Base Fee for every transaction. In September 2022, the Paris upgrade transitioned Ethereum's consensus mechanism from Proof of Work (POW) to Proof of Stake (POS), signaling the end of the machine mining era.

After the Shanghai upgrade, Ethereum's core development team announced that the most important update this year would be the Cancun upgrade, expected to occur later this year.

Cancun Upgrade: What Is It and Why Does It Matter?​

Named after the city that hosted the Ethereum Developer Conference (Devcon), the upcoming Cancun upgrade will implement crucial improvements to the Ethereum network.

The star of the upgrade, EIP-4844, aims to allow Ethereum nodes to temporarily store and retrieve off-chain data, fulfilling the data and storage needs of blockchain applications. If successfully implemented, EIP-4844 is expected to reduce the costs of Layer 2 (L2) rollup solutions. Reportedly, EIP-4844 has already been tested on four development networks, with a fifth testing network about to launch.

Originally intended for completion during the Shanghai upgrade, EIP-4844 was postponed to the Cancun upgrade. Developers have also agreed to include EIP-6780 (preparing for future application of Verkle Trees), EIP-6475 (providing improved readability and compact serialization), and EIP-1153 (introducing transient storage opcode) in the upgrade.

The Principle Behind the Upgrade​

The essence of Ethereum's scalability efforts lies in increasing data processing volume and speed. Two directions are pursued concurrently – Layer 2 rollups and sharding on the mainnet. The implementation of EIP-4844 is the first step towards complete sharding.

Prior to the Cancun upgrade, L2 information was stored in the Calldata of L1 information. This method was costly and limited due to Calldata's limited space.

With the Cancun upgrade, L1 will be stored in a new location called "Blob". Blob storage is more affordable and offers more space, allowing Ethereum to host more data, increase its transactions per second (TPS), and reduce costs. As Blob is a temporary data package cleaned up every 30 days, nodes only need to download a fixed amount of data per month, decreasing node burden.

In essence, the Cancun upgrade will make L2 cheaper and faster. This will not only benefit L2 protocols but will also foster rapid development for ecosystems built on L2.

In conclusion, the upcoming Ethereum Cancun upgrade promises to be an important milestone, heralding a new era of efficient, affordable, and scalable blockchain applications. Stay tuned for further updates as the Ethereum community continues its pioneering work in advancing decentralized technologies.

In recent times, discussions in the Bitcoin realm have seemingly transitioned towards the Bitcoin network itself, with BRC20 tokens emerging as a hot topic. People are contemplating whether the arrival of Bitcoin's Layer 2 (L2) expansion solutions and the BRC20 standard could introduce enhanced functionality and scalability to Bitcoin. However, it's important to tread carefully, as these discussions currently seem to lean more towards market speculation. Let's delve into Bitcoin's L2 architecture, BRC20, and potential security concerns.

Understanding Bitcoin’s L2 Architecture​

The blockchain ecosystem grapples with a so-called 'impossible triangle'—security, decentralization, and scalability—of which only two can be achieved at the cost of the third. Bitcoin, for example, has prioritized security and decentralization, sacrificing scalability in the process. Bitcoin’s block generation time is approximately 10 minutes, a significant lag compared to other popular blockchains like Ethereum 2.0 or Solana that boast block times on the scale of seconds or even milliseconds. This limitation has spurred demand for Bitcoin scalability solutions, leading to the emergence of Bitcoin's L2 expansion, exemplified by systems such as Stacks.

Stacks is a decentralized application and smart contract network built on top of Bitcoin. This network connects to the Bitcoin blockchain through a cross-chain consensus mechanism, achieving the goal of preserving Bitcoin's security while also offering a rich application scenario for smart contracts. Stacks operates in a layered fashion, where the base settlement layer (Bitcoin) is supplemented by the addition of smart contracts and programmability (Stacks), which further incorporates a scalability and speed layer (Hiro's subnet). This layered approach not only offers functionality akin to blockchains like Ethereum but also avoids many shortcomings of complex public chains.

Explaining BRC20​

To understand BRC20, we first need to familiarize ourselves with Ordinals. Ordinals is a protocol that assigns unique identifiers to Bitcoin's smallest unit, satoshis (sats), essentially transforming each sat into a unique non-fungible token (NFT), akin to Ethereum NFTs. Additionally, Ordinals allow for the inclusion of text, images, audio, and video within sats, further accentuating their uniqueness.

The creator of BRC20, leveraging the Ordinals protocol, introduced the concept of fungible tokens on Bitcoin by assigning a unified "format" and "attributes" to sats. BRC20, through Ordinals, inscribes JSON formatted text data into sats, acting as a ledger for BRC20 tokens and tracking token holdings and transfers.

Risks Associated with BRC20​

Despite the attention BRC20 tokens have garnered, they currently exist as mere JSON files without practical value or business use-case, and their popularity largely hinges on Bitcoin's popularity and traffic. Further, managing BRC20 tokens is not as straightforward as handling Bitcoin and requires a dedicated wallet. Moreover, participation in BRC20 investment requires third-party tools which often carry an entry barrier.

Several risks surround BRC20 tokens. Firstly, market speculation and hype may create a bubble, overvaluing the tokens. Secondly, similar to other blockchain technologies, BRC20 tokens are susceptible to hacking attempts. Lastly, the lack of regulatory oversight in the blockchain and cryptocurrency markets could lead to fraudulent or illegal activities involving BRC20 tokens.

A common misconception among users is that BRC20 tokens, created using Bitcoin's security, are as secure and stable as Bitcoin. However, the two are fundamentally different. Bitcoin's security is underpinned by cryptographic and consensus algorithms, and it has been running relatively stably for a considerable duration. Conversely, BRC20 relies on the Ordinals
