In Brief


    Ankr is excited to announce we have made an essential addition to our RPC service by integrating the Core Blockchain. This is excellent news for developers looking to get the jump on building on top of Core for decentralized apps secured by Bitcoin! Users will be able to access Core Public and Premium RPCs, make request calls, and receive information returns that are identical to the results they would get by running a Core full node themselves.

    Access free Core endpoints now.

    What is Core Blockchain?

    Core is a Bitcoin hash-powered layer one blockchain bringing Bitcoin miner governance to EVM-Compatible smart contracts. Its novel Satoshi Plus consensus combines Delegated Proof of Work and Delegated Proof of Stake, resulting in a secure, scalable, and decentralized chain. With a global network of experienced contributors and one of the fastest-growing and most diverse communities in crypto, Core’s ecosystem is expanding as builders and users come together.

    What Are Ankr’s New Core Blockchain RPC Connections?

    • Ankr’s Core RPCs (Remote Procedure Calls) connect wallets, command-line interfaces, and dApps with the Core blockchain. They act as a messenger or blockchain router that relays on-chain information between Core nodes, dApps, and ultimately end-users so they can execute necessary tasks like making transactions, populating wallet balances, fetching ownership information, and much more.

    • Core RPC endpoints are a gateway for developers to interface directly with the Core network — a portal to communicate easily, remotely, and with no need to go through the DevOps of establishing their own Core nodes.

    • Ankr is providing a geo-distributed Core RPC comprised of blockchain nodes running worldwide for incredibly low latency and reliable connections.

    How do the Core Blockchain RPCs Help Developers?

    Building with Core is an excellent choice to create secure and interoperable dApps, but requires access to the information on Core nodes to do so. Therefore, Ankr’s RPC solves the following developer troubles:

    Eliminates complex node ops - Ankr’s Core RPCs will completely remove the need for many developers to set up their own Core nodes, removing hours of time spent building, calibrating, and fixing node issues.

    Grants access to advanced tools -  Ankr’s Premium RPC Plan instantly grants access to the best tools to build applications quickly, including:

    • At least 90,000 Core requests/min
    • High request priority
    • Global node locations
    • Telemetry
    • Debug mode
    • Support Portal
    • WebSockets (WS) capabilities

    Powers apps and open-source software that need access to Core - Connect with a cluster of high-performance nodes that holds the information you need to build and operate dApps with Core capabilities.

    Supports the Core Blockchain - Ankr will strengthen the Core network globally by offering easier development and a broader, distributed node infrastructure.
