Sigilbase

Kafka, Redpanda, NATS, Pub/Sub, Event Hubs and Kinesis, sealed on arrival.

Sending records to Sigilbase through kafka, Redpanda, NATS, Pub/Sub, Event Hubs and Kinesis: every delivery receipted, every gap declared, and evidence your auditor verifies offline without an account.

Receivers ship in waves, and this one is in the second. Until then, anything that can send JSON reaches Sigilbase through the events API today.

What can be sent through Kafka, Redpanda, NATS, Pub/Sub, Event Hubs and Kinesis

Each record becomes an event in the ledger, kept exactly as it arrived with a hash of those bytes beside it.

  • Event stream

    Declared topics or subscriptions consumed by a collector you run, with committed offsets per partition as the cursor, so continuity is provable offset by offset.

How it will be collected

When this receiver ships, a collector you run consumes the declared topics with committed offsets per partition as the cursor, so continuity is provable offset by offset.

The evidence model

What every connector and receiver ships with, whatever the source:

  • A receipt per collection: what was asked for, what arrived, the cursor before and after
  • A declared gap for any interval nothing covers, never a blank
  • A daily settlement once late records can no longer arrive
  • The raw record, byte for byte, with its hash
  • An evidence bundle anyone can verify offline

What you get

  • Sealed as it arrives

    Every record is hashed and chained to the one before; every few minutes the chain is sealed into a signed checkpoint. A changed, deleted or reordered record fails verification at that exact point.

  • Continuity you can show

    The receipts chain too, so an auditor sees not only the records but that nothing between them went uncollected, and where a gap was, that it was declared.

  • Verified without us

    An export carries the open-source verifier. It runs offline, checks the chain, the receipts and the gaps, and needs no Sigilbase account. How the service is run.

Questions about Kafka, Redpanda, NATS, Pub/Sub, Event Hubs and Kinesis

  • Does Sigilbase support Kafka, Redpanda, NATS, Pub/Sub, Event Hubs and Kinesis?

    Receivers ship in waves, and this one is in the second. Until then, anything that can send JSON reaches Sigilbase through the events API today. Whatever arrives is written to a chained, signed ledger whose evidence anyone can verify offline with the open-source verifier, without a Sigilbase account.

  • What can be sent through Kafka, Redpanda, NATS, Pub/Sub, Event Hubs and Kinesis?

    Event stream: Declared topics or subscriptions consumed by a collector you run, with committed offsets per partition as the cursor, so continuity is provable offset by offset.

  • How will Kafka, Redpanda, NATS, Pub/Sub, Event Hubs and Kinesis evidence be collected and verified?

    When this receiver ships, a collector you run consumes the declared topics with committed offsets per partition as the cursor, so continuity is provable offset by offset. Every collection will be receipted in the connection's own stream: what was asked for, what arrived, and the cursor before and after. An interval nothing covers will be declared as a gap, never left blank. Exports carry the standalone verifier, which checks the chain, the receipts and the gaps offline.
