區塊鏈如何揪出河川污染元兇 | Using blockchain to uncover water contamination sources

過去這幾十年來,違章工廠與田地比鄰而居,排放出來的污染廢水,就由農作物吸收,進入我們身體。但政府的污染偵測器材卻又耗財耗時,無法及時反應環境污染情況,而我們身為一位小小公民,能做什麼解決這樣的困境?
自稱「程式碼農夫」的區塊鏈研究學者廖世偉,利用手上小小的離子交換樹脂膠囊,由台灣各地居民投放河川,放樣一週後收樣,水質紀錄立刻透過app上傳區塊鏈,其公開透明並無法竄改的資料特性,違章工廠的廢物排放馬上有了物證與上萬人證。
目前全台已經有一萬名由各地居民組成的「河川巡守隊」,守護著福爾摩莎這片土地。曾經只能仰賴政府做出改變的環境問題,透過現代科技,你我都能能為螞蟻雄兵,共同為環境與食安把關。你也願意一起加入這個行列嗎?

Over the past few decades, illegal factories throughout Taiwan have been secretly dumping hazardous wastewater in nearby streams, polluting neighboring cropland. Blockchain researcher Shih-wei Liao invented a cost-effective way to use sensors and big data to identify points of severe contamination. Here, Liao shares how there are innovative uses for blockchain technology other than in finance.
