1. 原句：This same technology allows them to use and even issue secure, self-sovereign digital identies to those involved with their programmes and more widely.

疑问：这里的more widely 修饰的是哪部分？

【答】more widely前面有and，说明与前句并列。为了简练，这是省略了前文的缘故。more widely 等于：use and even issue ... more widely。再举个例子：

Do your translation homework at once, and more carefully. 立即做你的翻译作业，要做得更加仔细。

2. 原句：Not only must the system be tamper-proof, it must be perceived to be so.

疑问：it must be perceived to be so 该如何翻译？

【答】it must be perceived to be so. 中，so 是替代词，指代前文的tamper-proof（防干扰的；防篡改的；防伪造的）：it must be perceived to be tamper-proof.

be perceived to be：被认为是......；被视为......；被认定为......；

这个句子的意思是：“该系统不仅必须是防篡改的，而且必须被认定是如此。”
