Select a nonce no longer than 32 bytes, such that when it is appended to the decoded form of the challenge identifier, and the entire result is hashed with SHA-256, the first {{ .Global.NeedBits }} bits of the SHA-256 hash are all zeros. Within one octet, higher bits are considered to come before lower bits.

-

In other words, find an nonce NN with |N|≤32B\lvert N\rvert \le 32\,\mathrm{B}, such that SHA256(I∥N)<2{{ .Global.NeedBitsReverse }}\mathrm{SHA256}(I \,\|\, N) < 2^{{{ .Global.NeedBitsReverse }}} in big endian, where II is the identifier provided below.

- +

Find an nonce that, when appended to the following string, results in a SHA-256 hash that begins with {{ .Global.NeedBits }} zero bits.

{{ .Identifier }}
-

Encode your selected nonce in base64 and submit it below.
