Cardano Node 11.1.0 dey prepare for Dijkstra and don remove old tracing

Cardano node 11.1.0 come out on August 21 with infrastructure changes wey dey prepare di network software for di Dijkstra era. Di update improve transaction processing, Plutus validation and node operations, but e require make node operators wey still dey use legacy tracing or di LMDB storage backend migrate their configurations.

Cardano Node 11.1.0 dey push Dijkstra Infrastructure forward

Cardano node na di core software wey dem dey use validate blocks, relay transactions and maintain synchronized copy of di Cardano ledger. Stake pool operators dey use am for block production and relay infrastructure, while developers dey rely on im interfaces to submit transactions, query network state and test applications wey dey handle ADA.

According to di official release notes, version 11.1.0 continue di technical groundwork for di Dijkstra hard fork, Cardano next major ledger era after van Rossem. Di update carry more efficient transaction forwarding between peers, mempool snapshots wey dem design make e remain fast as transaction volume dey increase, and quicker validation of Plutus scripts.

Di release still introduce initial network and consensus support for Ouroboros Peras. Di functionality dey disabled by default and e still dey behind di experimental NodeToNodeV_16 protocol version.

Peras dey designed to reduce transaction settlement time through additional voting certificates wey dem layer on top of Cardano existing Ouroboros consensus. Dem assign am to di second phase of di Dijkstra roadmap, separate from di first phase wey center on Linear Leios, Nested Transactions and new ledger era.

Legacy Tracing and LMDB need Operator Migration

Cardano node 11.1.0 don complete removal of di former iohk-monitoring-framework tracing system. Di newer tracing architecture na di only version wey dem include now, and configurations wey still dey reference legacy monitoring keys must migrate.

Cardano tracer don also drop di discontinued RTView component, while im optional metrics interface now follow di Prometheus wire format more closely.

LedgerDB V1 and di LMDB storage backend don also comot. Operators wey dey use LMDB must move go another supported storage option, with Cardano newer LedgerDB V2 architecture wey dey use LSM-based backend for on-disk UTxO storage.

Ledger snapshots now dey generated predictably and in format wey dey compatible with Mithril. Dis one allow snapshots wey different nodes create to dey compared and shared more reliably, while e support faster, independently verifiable synchronization.

Di Mithril signer binary dey also included inside di x86_64 Linux release package, so e reduce di number of separate components wey you need when you dey configure participation for Mithril signing.

Cardano Node 11.1.0 still dey Pre-Release Testing

Version 11.1.0 expand several interfaces wey infrastructure providers and developers dey use. Im experimental gRPC and UTxO-RPC layer add methods for reading and following di chain tip, accessing genesis information, searching UTxOs and evaluating transactions.

Di cardano-cli ping command now support multiple targets and DNS SRV records under CIP-0155. Container images for cardano-node, cardano-tracer and cardano-submit-api fit also operate as non-root users or with read-only filesystems, to provide additional deployment options for infrastructure wey dey support ADA transactions.

Di published requirements list 24 GB of memory for di in-memory backend and 8 GB for di on-disk configuration, although di latter figure still dey pending confirmation. One known issue dey produce approximately 12% higher memory use than version 11.0.1 when dem dey load testnet genesis files wey contain large amounts of pre-seeded data. Di release notes talk say Cardano mainnet no dey affected.

Performance benchmarks and system testing reports never still come out. Version 11.1.0 establish di configuration migrations, storage changes and experimental protocol interfaces wey people fit now test before later Dijkstra-ready release enter Cardano mainnet upgrade process.
