@oskarth So as discussed for this to be more useful with the metadata field. It makes sense to explicitly list what sequence a message is <local hash, remote hash, data, seqid> this way I can easily sync a messages prior or after a specific number. To enable this to be dynamic it might make sense to add page info so that I am aware which page I can find seqid on.

Also @oskarth add the remotelog to the readme.

@decanus do you mind if we merge this as draft? want to think a bit more about the seqid idea before just adding more stuff

[decanus]

@oskarth do it
