+# Base8
+
+The multibase base8 prefix is the character `7`. This spec is derived from
+RFC4648.
+
+## Encoding
+
+Map each 3 byte (8-bit word), with the most significant bit on the left side
+(big-endian) to 8 3-bit words as follows:
+
+`[⁰b₇₆₅₄₃₂₁₀, ¹b₇₆₅₄₃₂₁₀, ²b₇₆₅₄₃₂₁₀]`
+
+`[⁰b₇₆₅ ⁰b₄₃₂ ⁰b₁₀¹b₇ ¹b₆₅₄ ¹b₃₂₁ ¹b₀²b₇₆ ²b₅₄₃ ²b₂₁₀]`
+
+Treat missing subbits as zero and optionally pad.
