Web3的重點是區塊鏈,其中特點是可追溯性和透明度

Web3應用了區塊鏈技術,可以想像為無數本帳簿組成的記帳系統,帳簿和帳簿之間的數據是互通的,單一帳簿所做的修改都會同步到整個記帳系統,每一次的修改整個記帳系統都會有明確記錄。因而很難會發生「做假帳」的情況。每一個動作都是「可追溯」的,系統「透明度」非常高。

UN News以下這一段,正好解釋了「透明度」的重要性。正正因為每一條入帳都是可追蹤,大大減少了貪污舞弊的可能,對於監測資金運用和項目管理甚有幫助,亦可以令援助有效率並且直接到達受益人的手上。

One of the most useful aspects of cryptocurrencies, as far as the UN is concerned, is transparency.
Because the technology is resistant to tampering and fraud, it can provide a trusted and transparent record of transactions. This is particularly important in regions with weak institutions and high levels of corruption.
The World Food Programme (WFP), the largest UN agency delivering humanitarian cash, has found that blockchain can help to ensure that cash gets to those who need it most.
pilot programme in Pakistan showed that it was possible for WFP to get cash directly to beneficiaries, securely and quickly, without the need to go through a local bank. The project, Building Blocks, has also been successfully trialled at refugee camps in Jordan, ensuring that WFP could create a reliable online record of every single transaction.
If this can work for refugees, it can also work for other disadvantaged, vulnerable groups. The authors of a report by the UN environment agency, UNEP, suggest that the technology could improve the livelihoods of waste pickers, who eke out a living in the informal economy.
A transparent monitoring system, says the report, could accurately track where and how the recovered waste is used, as well as identifying who picked it, ensuring that the right people are rewarded for their efforts.
