第3112期:From Farm to Table: Blockchain Technology Will Bring Transformation

In a fantasy world, a celebrity chef like Aaron Sanchez would prepare all of your meals, and use only sustainably sourced organic produce.在幻想世界里，像亚伦·桑切斯这样的名厨会为你准备所有餐食，并且只使用原料来源可持续的有机农产品。Reality is everyone has to shop for and prepare our own food at some point.现实是每个人在某个时刻都得自己去采购和准备食物。How can you be sure that you're getting the best ingredients?你怎么能确定你买到的是最好的食材呢？That those organic vegetables are in fact organic. IBM thinks the solution lies in blockchain technology.怎么能确定那些有机蔬菜真的是有机的呢？IBM认为解决方案在于区块链技术。IBM is connecting the world's food supply from farmer to producer, supplier to manufacturer.IBM正在将全球食品供应链从农民到生产商、从供应商到制造商连接起来。And so we're connecting it in a secure, shared platform which is blockchain.我们将其连接到一个安全的共享平台，即区块链。A blockchain is a decentralized digital ledger, where transactions are recorded, verified and become permanent and immutable.区块链是一种去中心化的数字账本，会记录并验证每一笔交易，并且将永久留存，不可改变。With IBM Food Trust, a record of food's journey through the supply chain is created at each step. How exactly does it work?借助IBM食物信托平台，食品在供应链中的每一步旅程都会被记录。具体是如何运作的呢？So blockchain uses cryptography and we use hashing. And what that means is the information is connected to each other, and if you try to change the information, it changes the hashing, so that you know it has been compromised.区块链使用密码学，我们使用散列算法。这意味着信息之间相互关联，如果你试图更改信息，便会更改散列值，这样你就知道信息已被篡改。And the technology can be used for any number of foods, fresh or packaged.这项技术可以用于任何数量的食品，无论是新鲜的还是包装的。So our consumer can scan a package of scallops, and understand that it's coming from a place that sustainably source, and it is fresh and the best-tasting scallops.我们的消费者可以扫描一包扇贝，了解它来自可持续捕捞的产地，新鲜味美、口感最佳。For chefs like Sanchez, blockchain technology helps engender trust around the food distribution and handling process.对于像桑切斯这样的厨师来说，区块链技术有助于在食品分销和处理过程中建立信任。Before I mean you know the farmer would send it to a middle person, a distributor, and the distributor would send it to us, so it was one entity removed from the actual farmer.以前农民会把食材交给中间商，也就是分销商，然后分销商再转交给我们，我们和农民之间隔了一个环节。A foods traceability becomes especially pertinent in the wake of foodborne outbreaks.食品溯源在食源性疾病暴发后变得尤为重要。You know, instead of decimating the whole farm because there was one outbreak, now we can isolate to that one little parcel.以前一旦爆发疫情就得毁掉整个农场，现在我们可以只将隔离范围缩小到那一小块区域。With blockchain, farm-to-table takes on a new meaning.借助区块链技术，从农场到餐桌被赋予了全新的含义。
