This article examines how five major legal systems — the US, EU, China, Italy, and international model laws — treat on-chain timestamps, and why the distinction between &amp;lsquo;proving existence&amp;rsquo; and &amp;lsquo;proving identity&amp;rsquo; is the key to understanding their legal status.</description></item><item><title>Blockchain Timestamps as Prior Art: How On-Chain Proof of Existence Is Reshaping Patent Law</title><link>https://stampd.org/blockchain-timestamps-prior-art-patent/</link><pubDate>Tue, 02 Jun 2026 02:00:00 +0000</pubDate><guid>https://stampd.org/blockchain-timestamps-prior-art-patent/</guid><description>Blockchain timestamps are emerging as a powerful tool for establishing prior art in patent disputes. From Nym Technologies&amp;rsquo; use of a Bitcoin timestamp to invalidate a patent claim to China&amp;rsquo;s Internet Courts accepting on-chain evidence, this article examines how cryptographic timestamps are reshaping intellectual property law — and why every inventor should timestamp their work on-chain.</description></item><item><title>Blockchain Timestamps vs Traditional Notarization: A 2,000-Year History of Document Authentication</title><link>https://stampd.org/blockchain-timestamps-vs-notarization/</link><pubDate>Fri, 29 May 2026 02:00:00 +0000</pubDate><guid>https://stampd.org/blockchain-timestamps-vs-notarization/</guid><description>From the Lex Cornelia of 81 BCE to Bitcoin&amp;rsquo;s genesis block in 2009, the human need to authenticate documents at a specific point in time has evolved from human witnesses to cryptographic proof. This article compares blockchain timestamps and traditional notarization across five dimensions — cost, speed, security, volume, and legal recognition — and finds that while notarization verifies identity, blockchain timestamps verify existence, together forming a complete system of digital document authentication.</description></item><item><title>Blockchain Timestamps as Digital Art Provenance — From Quantum to CryptoPunks</title><link>https://stampd.org/blockchain-timestamps-as-digital-art-provenance-from-quantum-to-cryptopunks/</link><pubDate>Thu, 28 May 2026 02:00:00 +0000</pubDate><guid>https://stampd.org/blockchain-timestamps-as-digital-art-provenance-from-quantum-to-cryptopunks/</guid><description>Blockchain timestamps provide the strongest form of digital art provenance ever created — immutable, independently verifiable, and globally accessible.

&lt;p&gt;Time has always been a contested concept in philosophy. Augustine asked &lt;em&gt;&amp;ldquo;What then is time? If no one asks me, I know; if I wish to explain to one who asks, I know not.&amp;rdquo;&lt;/em&gt; Kant argued that time is an a priori intuition — a framework through which we perceive reality, not a thing in itself.&lt;/p&gt;
&lt;p&gt;Blockchains introduce a radical new concept: &lt;strong&gt;machine-verifiable time&lt;/strong&gt;. Not subjective human time, not Newtonian absolute time, but consensus time — time validated by cryptographic proof and distributed agreement.&lt;/p&gt;</description></item><item><title>What Is Timestamp Scarcity? The Fundamental Principle of Time Assets</title><link>https://stampd.org/what-is-timestamp-scarcity/</link><pubDate>Wed, 27 May 2026 06:00:00 +0000</pubDate><guid>https://stampd.org/what-is-timestamp-scarcity/</guid><description>&lt;h2 id="introduction"&gt;Introduction&lt;/h2&gt;
&lt;p&gt;In the physical world, scarcity is intuitive: there is only so much gold, oil, or land. In the digital realm, scarcity is engineered — Bitcoin proved that digital tokens could be made scarce through proof-of-work and a capped supply. But there is a deeper, less understood form of digital scarcity: &lt;strong&gt;timestamp scarcity&lt;/strong&gt;.&lt;/p&gt;
&lt;p&gt;Timestamp scarcity is the principle that the temporal position of a transaction within a blockchain is itself a scarce, verifiable, and potentially tradeable resource. Not all timestamps are equal. The first transaction in a block, the moment a particular event is recorded, or the ordering of trades in a decentralized exchange — each carries a unique weight that cannot be replicated.&lt;/p&gt;</description></item><item><title>Blockchain Timestamps as Legal Evidence: From China's Internet Courts to Global Jurisprudence</title><link>https://stampd.org/blockchain-timestamps-as-legal-evidence-from-chinas-internet-courts-to-global-jurisprudence/</link><pubDate>Wed, 27 May 2026 02:00:00 +0000</pubDate><guid>https://stampd.org/blockchain-timestamps-as-legal-evidence-from-chinas-internet-courts-to-global-jurisprudence/</guid><description>From China&amp;rsquo;s Supreme People&amp;rsquo;s Court recognizing blockchain evidence in 2018 to the UK High Court accepting Bitcoin timestamps as immutable records, the legal world is increasingly turning to on-chain timestamps as definitive proof of existence. This article examines the convergence of cryptographic timestamping and modern jurisprudence.</description></item><item><title>Haber &amp; Stornetta 1991: The Academic Origins of Cryptographic Timestamping</title><link>https://stampd.org/haber-stornetta-1991-the-academic-origins-of-cryptographic-timestamping/</link><pubDate>Tue, 26 May 2026 02:00:00 +0000</pubDate><guid>https://stampd.org/haber-stornetta-1991-the-academic-origins-of-cryptographic-timestamping/</guid><description>Stuart Haber and W.
