什么是区块链溯源技术？

洗澡蟹、瘦肉精，近几年来在市场上曾出现食物加吊白块（甲醛次硫酸氢钠）、家禽喂养激素、面粉加增白剂、海鲜用甲醛浸泡等，更有在水果上喷洒催熟剂、膨大剂，在绿色蔬菜上喷洒剧毒农药等都让老百姓们闻之变色，食品的安全与健康对我们越来越重要，所以这时就出现了区块链溯源技术——一种能让农产品从种植到出售全部可追溯的技术。

Bathing crabs, thin meat, food modifiers (sodium formaldehyde subsulphate), poultry hormones, flour and whiteeners, seafood formaldehyde soaking, etc., in recent years on the market, as well as spraying fruit with catalysts, swelling, spraying of highly toxic pesticides on green vegetables and the increasing importance of food safety and health for our people, have led to the emergence of the `strung' block traceability technology

在搞清楚区块链溯源技术之前，我们首先要搞清楚“追溯”和“溯源”的区别。

Before we understand the techniques of traceability of the block chain, we first need to clarify the distinction between “retroactivity” and “retroactivity”.

“可追溯”包括物流追踪和追本溯源两层含义。人们经常把追溯和溯源当成一回事，其实，企业在乎的是追踪（货物不要搞丢了），消费者在乎的是溯源（我买的到底安全不）。
三顷良田最大的特点就是可追溯性，这是保障食品安全强有力的手段。它从种植源头抓起，对源头、生产加工、清洗消毒、分装、包装、储存、运输、销售等环节层层把控。

“Reciprocity” includes the meaning of logistics tracking and traceability. Retroactivity and traceability are often taken as one thing. In fact, companies care about tracing (goods should not be lost), and consumers care about traceability (safety is not what I buy).
The greatest feature of the three good fields is traceability, which is a powerful means of guaranteeing food safety. It takes it from the source of cultivation and controls the chain layers of origin, production processing, sterilizing, sorting, packaging, storage, transport, sales, etc.

总之，确切的说，食品溯源是成本，是必不可少的前期投入，相当于对你的产品购买了一份“责任保险”。也许你一两年看不到效果，当你真的用到它时，可能就是救命的稻草。

In short, food traceability is a cost, an essential advance input, and it's equivalent to buying a “liability insurance” for your product. Maybe you can't see the effect for a year or two, and when you actually use it, it's probably a life-saving straw.
