Similarly, when minting 10'000 SBTs per second, it will take us 28'561 years to reach the limit. So, we don't need u128 nor the String type. However, if for some reason, we will need to get u64 support for JS, then we can always add another set of methods which will return String, so making it compatible with NFT standard (which is using `U128`, which is a string). Also, it's worth to note, that in 28'000 years JS (if it will still exists) will be completely different. The number of combinations for a single issuer is much higher in fact: the token standard uses classes. So technically that makes the number of all possible combinations for a single issuer equal `(2^64)^2 ~ 1e38`. For "today" JS it is `(2^53-1)^2 ~ 1e31`. -Token IDs must be created in a sequence to make sure the ID space is not exhausted locally (eg if a registry would decide to introduce segments, it would potentially get into a trap where one of the segments is filled up very quickly). +Token IDs MUST be created in a sequence to make sure the ID space is not exhausted locally (eg if a registry would decide to introduce segments, it would potentially get into a trap where one of the segments is filled up very quickly). ```rust // TokenId and ClassId must be positive (0 is not a valid ID)
