Due to these properties, the Bitcoin protocol is being used as a decentralized, trusted, and secure timestamping service. Although Bitcoin participants which create new blocks cannot modify their order, they can manipulate timestamps almost undetected. This undermines the Bitcoin protocol as a reliable timestamping service. In particular, a newcomer that synchronizes the entire blockchain has a little guarantee about timestamps of all blocks.\n  In this paper, ","authors_text":"Pawel Szalachowski","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-03-24T01:22:08Z","title":"(Short Paper) Towards More Reliable Bitcoin Timestamps"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.09028","kind":"arxiv","version":2},"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":"sha256:2c7a6b81b436827227acb77578bfe6fa6333f55d3f71d6765c392729752201f7","target":"record","created_at":"2026-05-18T00:15:41Z","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":"f94be146abed43c528926c6f06e247efc2bfd160153c09e5b4da07af50ce19d3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-03-24T01:22:08Z","title_canon_sha256":"8522a584ae5c7be1a8e01bedf208a844dddece55121060cffb44a749ce83a1a2"},"schema_version":"1.0","source":{"id":"1803.09028","kind":"arxiv","version":2}},"canonical_sha256":"c71a2e04cc29462a9b998c89ecf1ad33ac878b473aef4e933da9ebb5af728c72","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c71a2e04cc29462a9b998c89ecf1ad33ac878b473aef4e933da9ebb5af728c72","first_computed_at":"2026-05-18T00:15:41.676553Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:15:41.676553Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"OE5EuC7xTYgKUpEB0UrHVjRSZr48pU35aHR1YFE4XXXGDo5Ur4npZ4ummj9y5wkbSOFHnEyWzx09QLCliic+Bg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:15:41.677115Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.09028","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2c7a6b81b436827227acb77578bfe6fa6333f55d3f71d6765c392729752201f7","sha256:f9b5eb14aa3f6a8cbf467926da0445b84c03f45bb195afd598302693212ebba0"],"state_sha256":"b8d9dcb09d20594fa9356ff84fb53bc12e82a2ce7dbe0029b95de89fa354da71"}
