A major effort in this direction is Hyperledger, an open source project hosted by the Linux Foundation and backed by a consortium of over a hundred companies. A key component in permissioned blockchain protocols is a byzantine fault tolerant (BFT) consensus engine that orders transactions. However, currently available BFT solutions in Hyperledger (as well as in the literature at large) are inadequate for financial settings; they are not designed to ensure fairness or to tolerate selfish behavior that a","authors_text":"Alexander Spiegelman, Dahlia Malkhi, Idit Keidar, Kfir Lev-Ari","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2019-06-10T07:18:48Z","title":"FairLedger: A Fair Blockchain Protocol for Financial Institutions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1906.03819","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:a2c4788fa5d7b3f7f01122db62ac1222014122ab48a8e42dc507ab48f87515dc","target":"record","created_at":"2026-05-17T23:43:44Z","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":"eeafc1c3b49c6e5e21f32d1c0ad6fc6eeca0d113184185f2c4d29468f2e71a2d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2019-06-10T07:18:48Z","title_canon_sha256":"ae355776c184296eeb67037270451006fc88397831dd4c4bfde4297b1096ba9d"},"schema_version":"1.0","source":{"id":"1906.03819","kind":"arxiv","version":1}},"canonical_sha256":"58d629f44094f6106f6d50c183ae3dcadae7f1fcbc1d0a2aca0d9a4d31ee8be7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"58d629f44094f6106f6d50c183ae3dcadae7f1fcbc1d0a2aca0d9a4d31ee8be7","first_computed_at":"2026-05-17T23:43:44.869259Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:43:44.869259Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"iz86WRlfXYerYwyAGTL3CzuxNr5MOTtdXn9s5v/KQf4ncdAtXkRyBuYiqSHcDYMuYPYEMRlrlcfs18+gJ8XZDg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:43:44.869942Z","signed_message":"canonical_sha256_bytes"},"source_id":"1906.03819","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a2c4788fa5d7b3f7f01122db62ac1222014122ab48a8e42dc507ab48f87515dc","sha256:abda8b8e2de69193c8c89bf16656c53ebd2d3384421575c808002ed596b26097"],"state_sha256":"4f095440d0167c52c708e86a4bf4621f4451a560bcf35581e1996859e2faa265"}
