Introduction

Learn about Hemera Protocol, the programmable semantic data layer, powered by the first Account-centric Indexing protocol.

Introducing Hemera

Hemera Protocol turns crypto data into semantic values, thus providing utilities powering the decentralized AI future. The key to decentralizing AI resides in first democratizing data ownership and access, which is a given yet underutilized feature of web3. The biggest blocker of combining Crypto with AI lies in the absence of a public goods data infrastructure dedicated to streamlining semantic on-chain data processing.

Hemera creates account-centric indexing protocol to abstract away low-level on-chain data structures and smart contract logics for developers, while allowing them to express new assets and contracts in the form of User-defined Functions (UDFs) and share them with the protocol network. Powered by high performance indexing network, UDFs are updated continuously in real-time, allowing developers to build a wide range of Dapps. Hemera Protocol Network saves a small data team (from 1 to 5 people) for each end-user facing web3 team.

The "Why"

While blockchains excel at storing transaction data, today's AI systems depend heavily on account-level (user-level) semantic data to deliver personalized experiences. Features such as recommendation engines, search algorithms, and personalized AI assistants rely on individual user preferences and needs. However, the absence of infrastructure facilitating account-level semantic data retrieval poses a significant barrier in meeting these requirements.

Today the crypto world is already paying heavy prices for account-level data retrieval challenges:

  • New blockchains: every new chain needs a block explorer, yet there’s no high performance and affordable options in the market now. The leading block explorer costs millions of dollars per year, leaving the majority of new L1s and rollups out of options. Even more pressing is when high performance EVM chains are online, existing block explorer pricing model won't scale to the needs.

  • End users have high barriers and costs to access on-chain intelligence: end users are constantly looking across chain ecosystems for new assets to trade on, new communities to join etc. Yet accessing those information at scale is time consuming, requires coding capabilities sometimes, and may require expensive subscription to 3rd party softwares.

The "How"

Hemera proposes the first Account-centric indexing protocol, which creates a programmable and portable crypto data network that is not supported by traditional indexing protocols and providers.

Our Mission

Hemera is on a mission to “accelerate the advent of data and AI democratization”.

For too long, user data have been confined within the walled gardens of Internet giants, without us owning them. With Web3, user data is being democratized from these incumbents for the first time, and our goal is to accelerate this paradigm shift.

Get Started

Unlock your potential with the tools and resources offered by Hemera Protocol. From simplifying data interoperability to offering a decentralized infrastructure, Hemera provides a solid foundation for creating innovative decentralized applications.

For developers ready to dive in, check out these quick start resources:

Dapp builders, including wallets, gamefi, socialfi etc.: all consumer Dapps need access to user on-chain profiles, including asset holding history, social graph etc., yet building in-house functionalities can be as expensive as USD 50k per months or more including labor and server costs ().
