What if the way we think about owning digital assets… still misses the point?

I’m Jason Rudolph, founder of SALT, and in this first episode, we’re going back to the roots of crypto - to understand what self-sovereignty really means, why it’s harder than it looks, and how the next evolution of wallets could finally fix the trust problem that started it all.

My guest today is Jose Aguinaga - blockchain veteran, cryptography expert, and co-founder of Tungsten Custody (UAE). With nearly two decades in tech and institutional crypto, Jose brings deep insight into the evolution of digital custody - from the early days of mining Bitcoin at home to today’s complex world of multi-sig, MPC, and decentralised MPC wallets.

In this episode, we unpack:

• What the real promise of Bitcoin was, and how it shaped modern custody.
• Why multi-sig wallets revolutionised governance (and where they fell short).
• How MPC changed the game, and why centralisation crept back in.
• Why decentralised MPC might finally close the loop on trust.
• The future of AI agents, risk controls, and on-chain reputation.

Because if crypto is about owning your future, the real question is:
Who do you trust to protect it - you, or the math?
