This change introduces an autogenerated base58 digit table to remove the need to find the index of a character in the modified base58 alphabet each time. Additionally, it removes some unnecessary big integer allocations to cut down on the GC churn. Before: BenchmarkBase58Encode 20 64998995 ns/op 0.08 MB/s BenchmarkBase58Decode 50 35965928 ns/op 0.19 MB/s Now: BenchmarkBase58Encode 20 64644351 ns/op 0.08 MB/s BenchmarkBase58Decode 200 7914748 ns/op 0.86 MB/s
