@alexandratran there's an image here that still shows local + onchain permissioning, can that be updated - I think if you

• remove the "check onchain permissions" text from the diagram,
• instead of "Onchain and local", change it to "Local permissions checked" or "Local permissions applied"
• add something in the paragraph above it to say that the diagram shows where local rules are checked

then the diagram is still useful to show that when blocks come from other nodes, those local rules are not checked. On the other hand, you could say that with words and nuke the diagram.

Need to remove PRIV and EEA from this list of APIs- might also be under websockets
https://besu-docs-rnbr8w9as-hyperledger.vercel.app/public-networks/reference/cli/options#rpc-http-api

also there is some deleted content on this page that is unrelated to privacy/permissioning docs/private-networks/how-to/configure/consensus/add-validators-without-voting.md

[macfarla]

looks good overall. couple of changes requested

LGTM, just this diagram needs privacy removed - https://besu-docs-5ho4n9fb6-hyperledger.vercel.app/private-networks

[macfarla]

one more nit: can you replace eth_getWork in no-auth and also rpc-http-no-auth with debug_traceCall

[macfarla]

LGTM
