- If we think about the first phase of the commercial web, or web 1.0, think back to the period from the early 90s to roughly the mid 2000’s dominated by open protocols like http for content and smtp for email. The products and services offered in this phase were primarily digital translations of their analogue equivalent like newspapers, magazines, and photos and primarily static in nature. You can think of this phase the ‘read’ phase of the information superhighway. Then from the mid 2000s to now, the second phase of the web, Web2, was driven by advancements in cloud computing, mobile tech and the rise of social media to facilitate this shift from static desktop content to cloud and mobile based interactive experiences driven by user generated content. So in this more participatory internet with more ‘read/write’ capabilities, the user and their data became the product stored and sold by a handful of large centralized organisations where participants in a network did not really own any part of that network (for example a driver in the uber network ). Which brings us to Web3 and the promise of a dynamic and decentralized internet where users own their data and get a share of the value created in a network. Some of the key tenets of Web 3 include: ‘Open’ in that they are built from open source software built by an open and accessible community of developers and executed in full view of the world. ‘Trustless’ in that the network itself allows participants to interact publicly or privately without a trusted third party. ‘Permissionless’ in that anyone, both users and suppliers,can participate without authorisation from a governing body. ‘Composable’ - LEGO building blocks of open source code which can be combined to build new applications. With open source, it also means that any problems with the code only need to be solved once so development cycles in web3 can be blazing fast. Chris Dixon said it extremely well by saying that “think of composability to software as what compound interest is to finance” So broadly speaking, we think of web3 as the web owned by users and builders which is facilitated by this concept of a token and the underlying token economy to build and deliver the network value to the community of users and builders.
- So we at Covalent use this thought exercise to picture what 2025 looks like (and given the torrid pace of innovation in this space, it could even be sooner) We envision a thriving multi-chain ecosystem (with Ethereum at the lead of course :) powering thousands of dapps with most users unaware that blockchain is under the hood. And we’ll see those apps in every industry imaginable from finance, to gaming, ard, and government. So in this future, we can see that just an enormous amount of data is and will be created. This data includes NFT data.
- The challenge for developers - well let me ask you, what are some of the data challenges that you run into: Accessibility: Invest resources for custom queries Wait for data to be indexed Paying a lot for hosted service or data access Scalability Web3 data is messy so having a scalable solution to sort, filter, distill out the signal from the noise Limitations with making JSON-RPC calls - we firmly believe solutions needs to go above and beyond the JSON-RPC layer to scale. Having your DApp scale with increased costs With using hosted node infrastructure and requiring historical data provided by full archive nodes, already hitting 10TB of data Likely pay more for data Interoperability having to implement different solutions to access data from different protocols especially if they are non-EVM protocols. Ourselves saw this by our recent integration with Solana and the challenges it brought up to serve Solana data through our existing API framework Data challenges = friction + barriers for data -> hinder development of applications. Our vision of a solution to these Web3 data challenges is: Extra ******* So these data challenges all inevitably create friction and barriers for data which hinders mainstream adoption. Data must be free. Going above and beyond the JSON-RPC layer. So we summarize the Web3 data challenges for consumers into 3 key categories: Accessibility - challenges including needing to invest resources in developing custom queries, or having to wait for data to be indexed, or having to pay a lot for access Scalability - With protocols including Ethereum implementing tech like sharding and rollups to increase throughput or transactions per second, it just means there is a ton more data available and there are challenges with devs having the tools to access this explosion in data. Making JSON-RPC calls has its limits. Infrastructure providers running full archive nodes are hitting nearly 10 TB of data and will just pass off those costs to devs using their tools. Interoperability -having to implement different solutions to access data from different protocols especially if they are non-EVM protocols. We ourselves saw this by our recent integration with Solana. So these data challenges all inevitably create friction and barriers for data which hinders mainstream adoption. Data must be free. Going above and beyond the JSON-RPC layer. And so our vision of a solution to these Web3 data challenges is:

- The Covalent API is a unified API which brings visibility to billions of blockchain data points. Our motto is - One Unified API, One billion possibilities. So with just a single API, you can fetch granular and historical blockchain data across multiple networks with no code or delays. We index entire blockchains so that ALL the data is immediately available to consume.
- [Harish] the universal data model for multi-chain indexing and querying Where is Covalent headed? {click} Naturally progressive decentralization By decentralizing and bringing in partners to be a part of indexing, query and storage service, create flywheel More accessible data attracts more devs Creates greater demand for data But partners also want to grow their dev ecosystems so there are incentives for keeping network costs for data low Competing network participants also help to drive networks costs for data low This is how we see ourselves scaling as a core and critical piece of Web3 data infrastructure. {click} Where we are today - well on our way towards decentralization: Covalent Network is live (CQTscan) Open sourced the block specimen spec which sets a unified, canonical data model (CDM) for all blockchain data, regardless of the source Launch single sided staking on the Network next month ******* Which leads us to the question of where is Covalent headed? And the answer we believe is naturally progressive decentralization. The reason why this is a natural step from our perspective is because from a business model, we need to ask ourself if our current solution as a centralized indexing query and storage service scalable? Well we could throw up a pay wall and price data access accordingly to our costs but this would clearly have an effect on consumption and we believe it would hinder growth and development in a still a relatively nascent space. Our approach thus far has been to charge blockchains for indexing and serving up organized data so that ecosystems of developers may benefit from a free product that they can use for their experiments in Web3. By decentralizing and bringing in our blockchain partners to be a part of the indexing, query and storage service, we create a flywheel effect where more accessible data attracts more developers which in turn creates greater demand for data. And competing infrastructure providers are incentivized to keep the network costs for data low. This is how we see ourselves scaling as a core and critical piece of Web3 data infrastructure. And at Covalent, we are well on our way towards decentralization with our first critical component being open sourced which is the block specimen spec which sets a unified, canonical data model (CDM) for all blockchain data, regardless of the source. We have a detailed blog post on this if interested. Network announcement: https://www.covalenthq.com/blog/bsp-launch-announcement/ But now, onwards towards getting set up with our API key and checking out our endpoints. EXTRA (CDM is type of data model that presents data entities and relationships in the simplest possible form. It is generally used in system/database integration processes where data is exchanged between different systems, regardless of the technology used) The question revolves around i if our solution is scalable. This is how we as a core infrastructure scale to become a public good and the blockchains we index are part of the core infrastructure and running nodes. This inherently has the flywheel effect where more accessible data attracts more developers which in turn creates greater demand for data. All participants in the network benefit from this flywheel effect.
