December 18, 2023

Blockchain Node Engine is now integrated with VPC Service Controls. This integration offers enhanced access control options for admins at the organization level.

This integration is still in Preview and is ready for broader testing and use, but is not fully supported for production environments.

November 08, 2023

On November 8, 2023 Blockchain Node Engine released a limited preview version of the software. This release adds the Solana blockchain node option. Access to the user interface and APIs is limited to specific customers until GA release.

September 21, 2023

On September 21, 2023 Blockchain Node Engine released a limited preview version of the software. This release adds the Polygon blockchain node option. Access to the user interface and APIs is limited to specific customers until the GA release.

July 20, 2023

On July 20, 2023 Blockchain Node Engine added a self-managed nodes section and common setup instructions.

June 13, 2023

On June 13, 2023 Blockchain Node Engine became generally available. The user interface and APIs are now publicly available to all customers.

June 05, 2023

On June 5, 2023 Blockchain Node Engine released a limited GA version of the software. Access to the user interface and APIs is limited to specific customers until the full GA release.

Features supported in this release include:

  • Blockchain Node Engine is a fully-managed service for dedicated blockchain nodes.
  • Ethereum support:
    • Execution and consensus clients
    • Full and Archive nodes
    • JSON-RPC and WebSocket endpoints.
  • With a single operation, Blockchain Node Engine provisions a new node with the specified configuration (network, region, client, node type), bootstrap it from a known-good snapshot, sync it with the blockchain, and ensure its availability.
  • Google Cloud Armor always enabled.

March 22, 2023

On March 22, 2023, We released into private preview an updated version of the Blockchain Node Engine software.

You can now access a node's WebSocket server through the WebSocket API endpoint.

The WebSocket API unlocks the eth_subscribe and eth_unsubscribe methods, giving you powerful new ways to interact with your nodes.

See Using WebSockets for more information on Ethereum WebSocket.

March 09, 2023

On March 9, 2023, We released into private preview an updated version of the Blockchain Node Engine software.

You can now configure access to the admin and debug JSON-RPC API namespaces. This optionally enables access to a broad array of useful functions related to retrieving debug information from the node, and accessing administrative actions.

These fields may be omitted from node creation and default to false.

Note: for the time being these flags cannot be changed once a node is created.

February 09, 2023

On February 9, 2023, We released into private preview an updated version of the Blockchain Node Engine software.

Blockchain nodes created with the execution client GETH and consensus client LIGHTHOUSE now expose the JSON-RPC endpoint of the lighthouse client (consensus layer).

This feature allows you run your own validators by connecting the validator nodes to the consensus layer.

This feature also allows you to execute use cases involving deep inspection of the staking process.

The following features are now available:

  • Sepolia Testnet (supported for Geth/Lighthouse Full nodes)
  • Archive nodes (supported for Erigon nodes on Mainnet)

Sepolia Testnet is one of the preferred testnets for dApp developers. We currently support nodes running the Geth/Lighthouse clients on this network.

Archive nodes have the same capabilities as Full nodes, but also allow for querying historical data. Our first supported client for archive nodes is Erigon.

January 04, 2023

On January 4, 2023, We released into private preview an updated version of the Blockchain Node Engine software.

You can now select either Ethereum Mainnet or Testnet as options when creating blockchain nodes.

With the Testnet option, Blockchain Node Engine creates a different type of node that connects the Goerli-Prater Ethereum network.

November 30, 2022

On November 30, 2022 Blockchain Node Engine was released into a private preview.

Features supported in this launch include:

  • Blockchain support: Ethereum (Proof of Stake)
  • Administer "full" nodes via API
  • us-central1 regional support
  • Full RPC API
