In order to make such a system fault-tolerant, some form of redundancy becomes crucial, incurring various overheads - most prominently in terms of storage space and maintenance bandwidth requirements. Erasure codes, originally designed for communication over lossy channels, provide a storage efficient alternative to replication based redundancy, however entailing high communication overhead for maintenance, when some of the encoded fragments need to be replenished in news ones after failure o","authors_text":"Anwitaman Datta, Frederique Oggier","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2011-07-15T18:46:33Z","title":"Homomorphic Self-repairing Codes for Agile Maintenance of Distributed Storage Systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1107.3129","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:bdd3f872cf5b26f95cd85a3a69901d6d616a4faae286c081abd7f61b6b37ca12","target":"record","created_at":"2026-05-18T04:05:47Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"0ac1d10733e118d66505ee9ff9a77cebf27b22a469c6cc83972d0b7dae6256f0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2011-07-15T18:46:33Z","title_canon_sha256":"e0e69392cfe1d08b3addca81b857fbee29f649f18e52661518009e3ec38f51ff"},"schema_version":"1.0","source":{"id":"1107.3129","kind":"arxiv","version":1}},"canonical_sha256":"d4014ba25e55d45eaf396ade99b40b54873a16b863ad70663149c5b4b461ca3f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d4014ba25e55d45eaf396ade99b40b54873a16b863ad70663149c5b4b461ca3f","first_computed_at":"2026-05-18T04:05:47.214447Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:05:47.214447Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YmIkfDHC1AH4nbvGUsKHcQgjXH6DlvkXNeY5Bh5/kdl4yNii0sS/m4eqsXP50ZfED9qS68NBatd2X/eqfe8jCg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:05:47.214835Z","signed_message":"canonical_sha256_bytes"},"source_id":"1107.3129","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bdd3f872cf5b26f95cd85a3a69901d6d616a4faae286c081abd7f61b6b37ca12","sha256:0a2474b77b0bbeef694cbe4d5bef43cab640b95cb9b74a4ada23f537d9b8577f"],"state_sha256":"0a4049174f93c17e74a10ef1d66993829c7f620f8c741dd2b83f8c801bc8de0d"}
