A few days ago, I went to a restaurant in Little India for dinner and ordered six dishes. I repeated it twice with the waiter, but he didn't remember at all. Then I turned it back and asked twice, and repeated it twice, but in the end, he still served the wrong dish 。 Teasing with friends, this is the disadvantage of paperless office. My friend said seriously that this is not a paperless office. It was an ancient society where communication relied mainly on shouting. You need to be paperless first. Yeah, evolution is like this, relying on hard memorization with the brain → paperless (electronic office) → blockchain. Last time we talked about IOTA, this public chain from 10 years ago is still being developed. Perhaps due to the intense competition in the traditional track of public blockchains (DeFi, Meme, AI), they have found their own path, which is paperless/blockchain based international trade documents. According to a report released by IOTA, there are over 4 billion trade documents in circulation worldwide every day, and the wear and tear caused by these paperwork is not low. If estimated, it could be between $2 billion to $5 billion per year, and that doesn't even include time costs. So much so that the original intention of DHL, the commonly used international express delivery, was to transport various paper documents. As for blockchain, after more than ten years of development, the industry has indeed gone through the stage of "blockchain+can solve everything", but later it was found that: Either it's related but not professional (GameFi, Suansheng), or professional but not related (traceability, anti-counterfeiting, clearing and settlement), of course, there are also many that are neither professional nor related (live streaming, agriculture, even space) 。 But one thing to say is that these cross-border trade ledger issues are indeed one of the professional and corresponding directions of blockchain technology. The ledger related issues are the scenarios that blockchain is most adept at solving. Especially running ledgers on cheap public chains. I previously shared that IOTA has now fully shifted towards Sui Move and DAG consensus, and the performance of the entire chain is much more stable and affordable compared to ten years ago. Returning to the main topic, for example, in traditional trade, both parties trust the red seal of the customs and the signature of the carrier; If it is based on blockchain technology (such as TWIN in IOTA), the certificates issued by the government and enterprises are encrypted and signed, and the flow of NFTs in the browser can be viewed directly without the need for manual verification of authenticity. Traditionally, information flow, logistics, and capital flow are usually asynchronous (for example, goods have arrived but documents have not yet been sent); After being put on the chain, it is possible to achieve the integration of three streams (information flow, logistics, and capital flow synchronized on the chain), which is the "almost zero cost" and "faster customs clearance speed" mentioned in the original text. According to the report, IOTA has already started to digitize/blockchain cross-border trade in Europe and has accumulated a lot in developing regions in Africa. They have participated in the digitalization process of ADAPT in the African Free Trade Zone and established many pilot projects in Kenya, Ghana, the United Kingdom, and other countries. I hope everything goes smoothly for them and they can use blockchain technology to create some value at the technical level (not just at the capital level).
