Version 2.19.0.0

This is an optional release

Breaking changes

• Breaking only for users of Ansible and similar automation: CL_ARCHIVE_NODE and CL_MINIMAL_NODE are gone, replaced by CL_NODE_TYPE. Ditto for EL. See default.env for implemented values.

Changes

• Support Lighthouse with zkProofs attestations (Lean Ethereum), no execution layer at all. Here Be Dragons This is a highly experimental mode and is not rational to run right now, as there will be no timeliness rewards. Adjust .env:

COMPOSE_FILE=lighthouse.yml:mev-boost.yml
# Could be lighthouse-cl-only.yml. The main point is NO EL, plus any Grafana &c, mev-boost or commit-boost-pbs
CL_NODE_TYPE=pruned-with-zkproofs
CL_EXTRAS=--boot-nodes enr:-Oy4QJgMz9S1Eb7s13nKIbulKC0nvnt7AEqbmwxnTdwzptxNCGWjc9ipteUaCwqlu2bZDoNz361vGC_IY4fbdkR1K9iCDeuHYXR0bmV0c4gAAAAAAAAABoNjZ2MEhmNsaWVudNGKTGlnaHRob3VzZYU4LjAuMYRldGgykK1TLOsGAAAAAEcGAAAAAACCaWSCdjSCaXCEisV68INuZmSEzCxc24RxdWljgiMpiXNlY3AyNTZrMaEDEIWq41UTcFUgL8LRletpbIwrrpxznIMN_F5jRgatngmIc3luY25ldHMAg3RjcIIjKIR6a3ZtAQ
LH_SRC_BUILD_TARGET=ethproofs/zkattester-demo
LH_SRC_REPO=https://github.com/ethproofs/lighthouse
LH_DOCKERFILE=Dockerfile.source
MEV_BOOST=true
MEV_BUILD_FACTOR=100

and then run ./ethd update, wait for source build, and ./ethd up

• Support Grandine as a Nethermind plugin. This is experimental for now. Coming from grandine-allin1.yml, you'd adjust .env:

COMPOSE_FILE=grandine-plugin-allin1.yml:nethermind.yml
# Could also be grandine-plugin.yml; plus add whatever else the user runs such as commit-boost-pbs, grafana, &c
CL_NODE=http://execution:5052
NM_DOCKER_REPO=sifrai/grandine
NM_DOCKER_TAG=unstable-nethermind-1.35.8

and then run ./ethd update followed by ./ethd up

• Nethermind gained new pruning options: EL_NODE_TYPE can be rolling-expiry, which keeps 1 year of history by default, or pre-cancun-expiry, which does what it says on the tin. Note that rolling-expiry is still experimental
• Added Tempo support for traces to grafana.yml and grafana-rootless.yml. Clients that support traces will now send them there
  by default; if you know of a client that can and currently doesn't, please open an issue for it
• Grandine no longer defaults to aggressive pruning. The old behavior can be sought with CL_NODE_TYPE=aggressive-pruned
• Add another Grafana dashboard for host and node monitoring
• multi-line variables with single quotes are now supported in .env, example

HYPOTHETICAL_JSON_VAR='[
  "enode:something",
  "enode:anotherthing"
]
'
