Uncle Saba’s (www.unclesabas.com) 是一家专注于生产美味健康的零食领导者，其产品销往世界各地，例如美国、新加坡、加拿大、中国、韩国和日本等。作为促进可持续饮食目标的一部分，Uncle Saba’s 已经开始与PAI 区块链进行合作，旨在将透明性和可持续性纳入供应链管理。当准备就绪后，消费者可以通过扫描Uncle Saba’s罐子上的二维码在PAI区块链上查看有关食品中使用的原材料及生产地的信息。 同时，我们将尽最大努力将所有产品的信息都翻译成当地语言。
为此，我们使用了PAI区块链和PAI数据存储协议。在区块链上保存产品供应链的信息可以确保消费者获得的数据是及时准确且真实可靠的，不会被篡改。目前，常规的数据跟踪面临着物流和信息方面的挑战，例如随着产品从农场转移到下一个分支时，数据会存在不准确或过时的情况。
我们对Uncle Saba’s的解决方案提供了具体的案例展示。欢迎扫描下面二维码在PAI区块链上查看有关Saba产品的信息。
Project PAI 数据存储协议（简称”PAI数据”）是对Project PAI区块链协议扩展的一个规范，用来对任意数据进行保护和访问权限管理。PAI数据主要支持两种重要的交易类型：存储交易与共享交易。存储交易借助PAI区块链存储数据，可以用于对存储的数据的所有权进行声明；共享交易可用于在数据发送者与指定接收者之间授予或者撤销数据访问权，以此实现数据共享。
与其他基于区块链的文件存储系统（如IPFS/FileCoin, Storj, Permacoin, Spacemint等）相比，PAI数据存储协议的优势包括：存储空间提供者准入门槛更低，存储服务支付方式更灵活，数据传输效率更高。具体的内容，欢迎查看Project PAI数据存储协议论文。未来，我们会及时和大家同步我们在PAI区块链数据存储协议的最新研究进展和应用落地情况。

PAI blockchain and PAI data storage protocol provides Uncle Saba’s with food origin tracking and supply chain management solutions
Uncle Saba’s is a leader in producing tasty, yet healthy protein-packed snacks available in top retailers around the world, in countries such as the USA, Singapore, Canada, China, Korea, and Japan. As part of our mission to promote sustainable eating, Uncle Saba’s is working on a Proof of Concept with the open-sourced PAI Blockchain to bring transparency and sustainability into the supply chain. When ready, a user will be able to scan a QR code on a canister of Uncle Saba’s to see information on the PAI Blockchain about raw materials used in the food product as well as their origins. Best efforts will be made to make information available in the local language of the buyer of the chip.
Therefore, we use the PAI blockchain and its data storage protocol. Having information on the blockchain here serves the purpose of ensuring that data reported along the supply chain of a canister of Uncle Saba’s is timely, accurate, and resistant to being tampered with. Conventional data tracking faces logistical and informational challenges such as having inaccurate or outdated data as a product moves from farm to fork.
The Project PAI Data Storage Protocol (“PAI Data”) is a specification that extends the Project PAI Blockchain Protocol to include a method of securing and provisioning access to arbitrary data. There are two important transactions types that PAI Data supports: Storage Transactions and Sharing Transactions. A storage transaction is used to store data via the PAI Blockchain and can be used to make a claim of ownership of the stored data; A sharing transaction is used to share data by enabling data access granting and revocation between a sender and a designated recipient via the PAI Blockchain.
Compared with similar blockchain-based file storage systems (e.g., IPFS/FileCoin, Storj, Permacoin, Spacemint, etc), PAI Data’s advantages include but not limited to lower barrier to entry for storage providers, more flexibility in storage payment and higher efficiency in data transfer. For details, welcome to review the Project PAI data storage protocol paper. In the future, we will synchronize with you the latest research progress and application of the PAI blockchain data storage protocol in time.
We have made an illustration available ahead of this Proof of Concept. You can scan the QR code below and see information about Saba chips on the PAI blockchain.
