Searching and Processing Blockchain Data with dfuse

We spoke with Marc-Antoine Ross, CEO of dfuse, about how blockchain developers need methods to efficiently process large amounts of data.

Could you introduce dfuse for us?

dfuse is a massively scalable open-source platform for searching and processing blockchain data. dfuse empowers developers with the capabilities they need to build modern blockchain applications with fast, fluid interfaces that deliver exceptional user experiences.

dfuse began its journey by seizing an opportunity to support the launch of the most performant blockchain software available, EOSIO, and providing open-source tooling. This involvement gave us first-hand knowledge of both the capabilities and the limitations of the latest generations of blockchain technology.

After quickly positioning ourselves as one of the technical leaders within the EOSIO software community, we were sought out by hundreds of developers who shared their challenges and obstacles when building on blockchain. This experience quickly identified the missing piece of the puzzle to put blockchain within reach of every developer: powerful APIs for reading and accessing blockchain data.

We quickly rolled out a query layer for EOSIO, bringing true searchability to blockchain for the first time ever. In October of 2018, we launched the free public beta of dfuse to the global community of EOSIO developers.

What does dfuse offer today?

dfuse’s primary goal was to make interacting with blockchain data as simple as interacting with standard databases. This meant building out custom APIs that delivered the performance, reliability, and high availability that developers were used to. Armed with a team of big data engineers, security experts, and top dev ops engineers, we knew that we could deliver this to the blockchain community in a way that had never been seen before.

Since that time we have been working to further deepen our platform capabilities. Today, our blockchain data stack is composed of 4 products, offered over REST, Websocket, GraphQL and gRPC APIs:

  • dfuse Search: Real-time, historical and fork-aware search engine that enables you to search the entire transaction history of the blockchain using a simple but powerful query language, with sub-second response times.
  • dfuse State: Offers snapshot views of the blockchain state, at any block height historically, in real time and is fully fork-aware.
  • dfuse Lifecycle: Track the lifecycle of a transaction as it changes state: pending, included in a block, forked, replaced, failed, expired, etc.
  • dfuse Push Guarantee: Submit transactions to the blockchain and receive guaranteed irreversibility in a single call, eliminating the need to write complex code to handle and recover from intricate failure cases.

We built dfuse from first principles, asking ourselves how we would want to read blockchain data if we weren’t constrained by the standard JSON-RPC interfaces. We provide higher-level blockchain APIs, which do more, with less effort, than the native APIs provided by blockchain nodes.

Why did you decide to use blockchain technology, and specifically EOSIO?

Simply put, our background in delivering solutions in other high-throughput environments led us to the blockchain platform that had the highest throughput: EOSIO.

Capable of thousands of actions per second, it was clear that EOSIO would need a great solution for reading that data. Coupled with fee-less transactions, it was clear that data (and not just value transfers) was going to be a big part of the future of EOSIO blockchains.

Developers love data, and need to be able to manipulate it. Whereas with other blockchains that were simply stores of value, there was yet to be a pressing need for a product that delivers the level of detail that dfuse does.

What stage is dfuse at?

dfuse is currently deployed on many blockchains based on EOSIO and Ethereum technologies (including public networks, consortium chains, and private chains). Other blockchain protocols are under active development. 

dfuse provides the massively scalable infrastructure for hundreds of public and private deployments, including exchanges, trading operations, interactive games, social media platforms, supply chain solutions, and high-throughput regulated environments. From hobbyist to multinational enterprise, dfuse can keep up with your needs.

What are the challenges you have had to overcome, and how did you do it?

The EOS Public Blockchain is unlike any other platform out there today. Its high transaction throughput and subsecond block times mean that the amount of blockchain data which must be stored by history providers can increase quickly.

Thanks to proper planning and foresight, we have developed our infrastructure to scale with the demands of the blockchain, enabling us to keep our users’ applications fed with the data they need to service their users. By initially architecting dfuse to handle the millions of transactions per second that strives to deliver with EOSIO, we have been able to scale our offering to provide reliability.

What are your plans for scaling?

Every day, we speak to more Enterprise users who are looking to integrate blockchain technology. Their needs are unique, but as we deliver solutions, those improvements trickle down to our global service. In turn, this creates a more robust and feature-rich service, creating a positive feedback loop. Our plan is to continually listen to those who seek out blockchain data, and figure out how to best deliver it to them. 

We are also developing solutions across different blockchain platforms, listening to the needs of developers across the entire blockchain ecosystem. We believe that in the future, developers will be multi-chain enabled. Rather than having to learn the nuances of interacting and reading from each blockchain, dfuse can be a middle layer that obfuscates complexity, while offering the benefits found from each platform.

What EOSIO community initiatives have you engaged in and how has the community responded to dfuse?

Most proudly, as the dfuse Platform, we open sourced our blockchain data stack under the Apache 2.0 license with embracing our solution. Open sourcing the dfuse data stack empowers developers to build better blockchain applications with free access to the most performant and scalable platform available.

It helps accelerate development efforts to integrate dfuse on additional blockchain platforms, as well as to develop extensions such as low-latency syncs, specialized indexers, big-data analytics, and block explorers, and help drive the discovery of new applications and use cases.

In addition, dfuse has contributed many open-source developments to the EOSIO ecosystem:

  • dfuse Community Edition – Launched and hosted by EOS Nation, dfuse Community Edition is a freely available set of dfuse APIs. The mission is to provide greater access to data for all developers seeking to integrate with the EOS Public Blockchain.
  • eosq – The most in-depth and high-precision block explorer available for an EOSIO network. A GUI for dfuse, it has access to all of the unique information that dfuse exposes.
  • eosc – The most flexible and powerful command line tool for any developer to interact with an EOSIO chain.
  • – A smart contract to handle asynchronous voting and messaging by account holders on an EOSIO network. Adopted to handle the needs of a referendum system for the EOS Public Blockchain. Also utilized to back a Reddit-style threaded forum, with all messages placed on chain.
  • EOS BIOS Boot – We spent countless days and nights onboarding Block Producer candidates to EOSIO through the first open-source tool to launch a blockchain in a decentralized fashion.
  • eosio.unregd – A smart contract containing the information of all Ethereum addresses of users who did not successfully register their accounts to claim their EOS tokens upon launch of the EOS Public Blockchain.

This brought the barrier to entry to almost nothing for a developer when deciding on a multi-chain deployment.

Where do you see dfuse in the future?

We foresee dfuse as being the Elasticsearch of the new decade: an open-source platform for streaming and manipulating blockchain-based databases and data flows. 

We are building a solution to empower developers with better queries and streaming semantics than blockchain nodes can ever natively provide (because nodes are optimized for a different role). 

dfuse aims to enable massively parallel operations on ever-growing log-based blockchain databases and to offer performance that scales beyond what is currently being worked on by the most ambitious protocol teams.

In just one sentence, how do you want readers to remember dfuse?
