Since Bitcoin would be built on decentralized ledger technology, a blockchain needed to be established as the foundation for the cryptocurrency.\u00a0<\/p>\n<p>Since 2008, blockchain technology has expanded well beyond cryptocurrency usage and is now being <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lied in a variety of use cases from healthcare to finance to green tech and more.<\/p>\n<p>But blockchain tech didn\u2019t start with Satoshi\u2019s white paper. It was actually invented in 1991 as a way to verify and protect content through a concept called timestamping.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"A_blockchain_history_lesson\"><\/span>A blockchain history lesson<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In Satoshi\u2019s famous Bitcoin white paper, he cites another paper: \u201cHow to Time-Stamp a Digital Document,\u201d <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/link.springer.com\/chapter\/10.1007\/3-540-38424-3_32\">published<\/a> by Stuart Haber and W. Scott Stornetta in 1991. The two researchers knew that, in an all-digital world, the issue of certifying documents \u2014 when they were created and when they were changed \u2014 would become an issue.<\/p>\n<p>They explained that in the past, you could simply flip through the pages of a notebook to see dated entries. They cite other means of certification, such as mailing oneself a letter or having something notarized, but in those cases, tampering of documents would be discovered im<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>tely. But not so in a digital world, where documents can be altered with no evidence left behind.<\/p>\n<p>\u201cThe problem is to time-stamp the data, not the medium,\u201d they wrote. The first solution they proposed was to simply send a document to a timestamping service. The TSS would then retain a copy for safe-keeping, which could be brought out for comparison when needed.<\/p>\n<p>What is the problem with this solution? It relied on a third party that might mishandle it.<\/p>\n<p>Instead of a third-party verifier, they would use a cryptographically secure hash function, which would serve as the unique identifier for a piece of content. Instead of sending the whole document to the TSS, the creator would send the unique identifier instead. Upon receipt, the TSS would make a confirmation with a digital signature. By checking the signature, the client would be assured that the TSS actually did process the request, that the hash was correctly received, and that the correct time was included.<\/p>\n<p>But what happens if the TSS puts a false timestamp on the hash? Haber and Stornetta proposed two solutions: (1) Use bits of previous requests to create new ones, which forces a chronological record; and (2) Make the whole system decentralized, transparent and checkable.<\/p>\n<p>For anyone familiar with how blockchain technology works, this is it. Blocks are created by drawing from the hash of the last block and solving the hash of the new block. Once a block is added, it\u2019s verified by nodes on the blockchain in a decentralized system and locked into the public ledger, unable to be altered.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Original_use_cases\"><\/span>Original use cases<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Haber and Stornetta outlined use cases for this kind of time-stamping, citing inventions or ideas where authorship would need to be proven. Because the documents are recorded as hash functions, it timestamps intellectual property and patents without revealing the contents. They also cite examples where, if a company has documents that were tampered with, they can prove the originals through the timestamp. They envisioned timestamping to encompass not only text documents but original audio recordings, photos, videos and more.<\/p>\n<p>While Haber and Stornetta eventually went on to create their own company called Surety, which acted as that TSS (and, interestingly, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/btcmanager.com\/finding-the-oldest-blockchain-in-the-new-york-times-classifieds\/\">published<\/a> their hashes in the New York Times classifieds every week starting in 1995), but the idea never fully caught on. It wasn\u2019t until Bitcoin was created in 2008 that blockchain technology was finally fully created \u2014 four years after Haber and Stornetta\u2019s patent on it <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/cryptonews.com\/news\/a-key-insight-for-the-blockchain-came-in-1991-1895.htm\">ran out<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_do_we_need_timestamping_today\"><\/span>Why do we need timestamping today?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The need for authenticating documents wasn\u2019t just a 1990s concern. In a world where there\u2019s so much digital content being produced and when distrust in content on the internet seems to be growing, timestamping might just be the way to achieve the transparency and accountability that\u2019s needed.<\/p>\n<p>The idea is simple. A unique hash is generated from a piece of content\u2019s text, title or date, and is added to the blockchain. This not only locks in the time at which a piece of content was created to a public distributed ledger but if any part of that content is altered, the hash alters too \u2014 showing that it was tampered with or that a new version was created.<\/p>\n<p>This allows content creators to be able to prove at any time that they created the piece by calling it up on the blockchain. Timestamping can also <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/wordproof.com\/academy\/timestamps-for-copyright-protection\/\">put an end<\/a> to plagiarism and copyright disputes since original work can be found linked to its hash in an immutable blockchain.<\/p>\n<p>Timestamping also increases trust for readers. With added identity tiers, they can know exactly who wrote the content and when and can view an authentication certificate. The more sites that adopt timestamping, the more readers will get used to associating timestamping with transparency, accountability and authenticity \u2014 and will reject any unverifiable content that not timestamped. Timestamping has a use case in e-commerce as well, where buyers can see original terms and agreements and not be cheated by a suddenly updated version that nulls a warranty.<\/p>\n<p>With a simple implementation, the internet could become a safe, trusted place where authors can feel confident their content will remain secure, and where readers know that what they\u2019re reading is verifiable. It\u2019s been a long time since the original paper in 1991, but those ideas are needed today.<\/p>\n<p class=\"post-content__disclaimer\"><em>The views, thoughts and opinions expressed here are the author\u2019s alone and do not necessarily reflect or represent the views and opinions of Cointelegraph.<\/em><\/p>\n<div>\n<div style=\"background: rgb(239, 239, 239); border: 1px solid rgb(204, 204, 204); padding: 10px;\"><strong>Sebastiaan van der Lans<\/strong> is the chairman of The Trusted Web Foundation as well as founder and CEO of WordProof.
