Changelog

Fixed subscription deduplication bug.

Usage notes

You will need to specify WS endpoints for all RPCs in your config file, otherwise Blutgang wont run. This is a pre-release thing. See the example config for how to do this.

Docker containers

Docker containers are available here https://hub.docker.com/r/makemake1337/blutgang-prebuilt and https://hub.docker.com/r/makemake1337/blutgang under the 0.3.0-canary2 tag.

Blutgang 0.2.0 Myrddin

Blutgang 0.2.0 Myrddin is the next major release of Blutgang. It includes major changes to Blutgang, designed to improve its performance and usability in production environments.

We plan to iterate on the new features added in the following minor releases. Please contribute to the discussion here: #33

Changelog:

Add blutgang RPC namespace (#32)

Add the blutgang namespace for JSON-RPC requests that can be used by admins to change settings and view stats while blutgang is running. Please consult the wiki on how to use it.

Blockless RPC selection (#28)

Select RPCs without blocking any other tasks/threads. Major latency improvement in high load test scenarios.

Add xxhash as an alternative to blake3 (#31)

xxhash can now be used as an alternative to blake3 for even more performance. xxhash has 64 bits of entropy, and unlike blake3 is not cryptographically secure. Generating collisions is non-trivial.

Replace serde with simd_json (#30)

serde_json is pretty slow for our usecase, so we swapped it out for simd_json. Note: While better than serde simd_json, is still sub optimal, as there are further optimizations that can be made which are currently only available in nightly rust.

Basic request rewrite support

Rewrite named blocknumber params("safe", "finalized", etc...) to their respective number counterparts. This reduces overall load and increases throughput as more requests can be cached.

Note: Not fully implemented, full support coming with websockets in the next major release.

Major stability improvements

Blutgang is now much more stable and resilient from mangled/invalid requests and responses.

balancer rewrite (#29)

Large chunks of balancer have been rewritten to make it easier to work with

More verbose errors

The errors blutgang produces are more verbose.
