bdb 6.X was released under the AGPL, which is incompatible with MIT-licensed software (the result must be licensed under AGPL). bdb 5.X uses the same license as bdb 4.8, and thus retains the same compatibility as in upstream Bitcoin. Thanks to Luke-Jr for raising this issue.

What is Zcash?
Zcash is an implementation of the "Zerocash" protocol. Based on Bitcoin's code, it intends to offer a far higher standard of privacy and anonymity through a sophisticiated zero-knowledge proving scheme which preserves confidentiality of transaction metadata.
Zcash is unfinished and highly experimental. Use at your own risk.
Participation in the Zcash project is subject to a Code of Conduct.
