Amilcar Giménez resolved NIFI-14838.
------------------------------------
Resolution: Won't Do
As seen in the pull request, this implementation was considered to be for a
very specific use case, and keeping it aligned with the NiFi codebase may
require additional effort.
The implementation has been published to the Maven Central Repository for
anyone who wants to use it.

> Add Ethereum Beacon Chain Event Processor and Controller Service

> Key: NIFI-14838
> URL: https://issues.apache.org/jira/browse/NIFI-14838
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Affects Versions: 2.6.0
> Reporter: Amilcar Giménez
> Assignee: Amilcar Giménez
> Priority: Major
> Time Spent: 40m
> Remaining Estimate: 0h
>
> I want to provide an integration with the Ethereum Beacon Chain so NiFi users
> can consume consensus-layer events (SSE) from {{/eth/v1/events}} and build
> dataflows for monitoring, analytics, alerting, and archival. The Beacon Node
> API is standardized and widely implemented by clients such as Lighthouse,
> Teku, Nimbus, Prysm, and Lodestar.
> Proposed Components
> *Controller Service:* {{BeaconChainClientService}}
> * Purpose: Manage connection/config to a Beacon node and expose an event
> subscription client.
>
> *Processor:* {{ConsumeBeaconChainEvents}}
> * Purpose: Connect to the controller service and specific events, convert
> each event to a FlowFile (JSON) with useful attributes, and route to
> {{{}success{}}}/{{{}failure.{}}}
>
> I created a public library under the MIT licence in order to connect to a
> node through the Beacon Chain API, and I use it for this processor:
> [Am-ilcar/eth-events-listener|https://github.com/Am-ilcar/eth-events-listener]
> This can be useful for other developers too.
