More doublespeak from crypto fetishists.
> 'it is secure as long as one person forgets their secret'
This is from the 1-of-N security assumption of the cryptographic procedure, wherein at least 1 person is actually honest and destroys their own secret to ensure its security. With a large enough N, this security assumption is made guaranteed due to the non-zero probability of human nature for deviant behavior from the rest of the group, wherein at least 1 person will be honest and perform as specified.
> 'we need to protect against sybil attacks (so sign in with your github account)'
...this claim ignores the large visible button right above the 'or unlock with Github' link, that prompts the user to sign in with their Ethereum address.
Aside from this, this is meant as one of the 2 methods of preventing bot spam, the other one being the sign in using an Ethereum address.
> More doublespeak from crypto fetishists.
Doublespeak is not present, joosters, as the two claims address different issues (1-of-N security of the KZG ceremony & bot spam).
You can imagine an extreme case of a ceremony only allowing for 5 contributions. Wouldn't you want to have some sort of protection against all 5 of those contributions being from the same person?
