Octez DAL Node RPC (Octez 24.1 (1b272698))

Performs health checks on the DAL node, evaluating key components of the DAL node. Returns a health status indicating whether the DAL node is 'Up', 'Down', or 'Degraded' based on the results of these checks.

Returns the last (finalized) L1 level which was processed by the DAL node.

Return the commitment associated to the given slot index and published at the given level, if any. The commitment is fetched from the skip-list storage. Note that the commitment is not present in the storage immediately after publication, but only when its attestation status is known and final.

Retrieve the content of the slot whose id is given.

Fetch slot as list of pages

Compute the proof associated with a page of a given slot.

Fetch shard as bytes

Return the status for the given slot. For operator nodes only.

Returns the stream of synchronization statuses of the DAL node with the L1 node.

Connect to a new peer.

Get the backoffs of the peers with a backoff, per topic.

Get this node's currently active connections.

Returns the fanout peers per topic alongside the last publication time on the topic.

Get the mesh of the peer. Concretely, the RPC returns a list of topics, where each topic is associated to the remote peers with which the current node shares a full connection (on that topic). Optional arguments allow to restrict the output to a given delegate or slot index.

Get the number of message ids in the message cache, grouped by heartbeat tick and topic.

When the 'all' flag is given, get an association list between each topic subscribed to by the connected peers and the remote peers subscribed to that topic. If the 'all' flag is not given, then restrict the output to the topics this peer is subscribed to.

For each unreachable point, retrieve the time remaining until the next reconnection attempt.

Get the scores of the peers with a known score.

When the 'all' flag is given, get an association list between each public key hash part of a topic subscribed to by the connected peers and the remote peers subscribed to such topics. If the 'all' flag is not given, then restrict the output to the topics this peer is subscribed to.

Get the topics this node is currently subscribed to.

When the 'all' flag is given, get an association list between each topic subscribed to by the connected peers and the remote peers subscribed to that topic. If the 'all' flag is not given, then restrict the output to the topics this peer is subscribed to.

By default, get the list of known peers. When the 'connected' flag is given, then only get the connected peers.

Get info of the requested peer

Change the permissions of a given peer. With {acl: ban}: blacklist the given peer and remove it from the whitelist if present. With {acl: open}: removes the peer from the blacklist and whitelist. With {acl: trust}: trust the given peer permanently and remove it from the blacklist if present. The peer cannot be blocked (but its host IP still can). In all cases, the updated information for the peer is returned. If input is omitted, this is equivalent to using the GET version of this RPC.

Disconnect from a peer.

Get list of known peers and their corresponding info.

By default, get the list of known points. When the 'connected' flag is given, only get the connected points.

Get info of the requested point

Disconnect from a point.

By default, get the list of known points and their corresponding info. When the 'connected' flag is given, then only get the connected points.

Return the list of current profiles tracked by the DAL node.

Update the list of profiles tracked by the DAL node. Note that it does not take the bootstrap profile as it is incompatible with other profiles.

Return the shard indexes assigned to the given public key hash at the given level.

Return the currently attestable slots at the given attested level by the given public key hash. A slot is attestable at level [l] if it is published at level [l - attestation_lag] and all the shards assigned at level [l] to the given public key hash are available in the DAL node's store.

Stream attestable slot ids for a given public key hash [pkh]. A slot is attestable for attested level L if it was published at (L - attestation_lag) and all shards assigned at level L to [pkh] are available in the DAL node's store. If some shards of the slot are detected as traps for the baker, the slot should not be attested, so the id is not sent via the stream.

Returns the protocol parameters as known by the DAL node. An optional 'level' argument can specify for which level to retrieve them.

For a given published level, return all the traps known by the node. Optional arguments allow to restrict the output to a given delegate or slot index.

Post a slot to the DAL node, computes its commitment and commitment proof, then computes the correspoding shards with their proof. The result of this RPC can be directly used to publish a slot header. If the sent data is smaller than the size of a DAL slot, it is padded with the character provided as padding query parameter (defaults to \000). If the slot_index query parameter is provided, the DAL node checks that its profile allows to publish data on the given slot index. However, slot_index is optional and has NO SEMANTIC EFFECT on the produced commitment. It exists solely to help reverse proxies route POST /slots requests to a DAL node subscribed to the corresponding topics.

Returns the current synchronization status of the DAL node with the L1 node.
