Yeah, you can buy Zcash devs to implement Zcash technology into Tezos, but this won't make you a leading blockchain. Money can buy solutions to problems, but you are lagging behind, you are just copying others and will be behind others. Bolt is already obsolete Zcash technology and will be replaced with a layer 1 solution called HALO.
"Bolt is a way to scale Zcash privately as a second layer solution, unlike LN which has privacy leaks when closing and opening channels.
With that said, Zcash is more likely to adopt a first layer scaling solution called HALO to kill two birds with one stone, massive scaling and getting rid of the trusted setup zkSNARKs require:
BTW - where is Tezos layer 2 scaling solution Marigold??? After all these years we haven't heard a shit about it. Is the project still getting Foundation funding?
Tezos can have 600 million dollars in warchest, but Tezos project will never have as competent blockchain developers as the Zcash project has. Never. This sorry ass project will always be copying others and lagging behind.
