How this entity was disambiguated
This entity first appeared as the object of triple T19401744 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Bit Gold
Bit Gold is a pioneering early digital currency proposal by Nick Szabo that introduced key concepts later used in cryptocurrencies like Bitcoin.
-
D.
Equihash
Equihash is a memory-hard, proof-of-work hashing algorithm designed to be ASIC-resistant and used in cryptocurrencies such as Zcash.
