经过实测，keystone的骰子生成助记词和 经历了coldcard被盗事件，我就想用完全自己收集熵，来生成助记词，并且要求完全可验证。所有冷钱包和app 钱包都说自己的随机数是安全的，用最高级的随机数生成器，但是我无法验证，就像coldcard使用了安全芯片，但是在最终生成助记词的时候却没有调用该芯片，所以我就想找一种能自我验证的随机数生成方式，后来看到了keystone的推文，keystone支持骰子生成，正好我有keystone钱包。 但是下一个问题，我怎么验证keystone使用骰子生成的助记词是安全的，怎么证明它用的熵就是我提供给它的那一个？之前研究过 经过实测，keystone的骰子生成助记词和 据说trust wallet也支持该功能，明天找时间再验证一下trust wallet @KeystoneWallet @KeystoneCN
