Decentralization of finance is a spectrum enabled by
1) distribution of trust/responsibility
2) transparency
Not all #OpFi will be 'fully' decentralized.
But what makes it sufficiently different is transparency.
It will be shrouded in the complexity of code and mechanism design.
But it will undoubtedly be more open than the closed, centralized systems of today.
* Easier auditability >>
* Better risk management >>
* Better governance >>
And ideally -- through much trial and error -- simpler, more effective *core* financial systems.
In 10 years, they will be staffed with hundreds or thousands of hybrid financial-engineers who are experts in Solidity or other financial contract code and design.
This will come only by doing.
If we're careful, we'll move in measured steps. Two steps forward, one step back.
This has the potential to go spectacularly well or wrong.
One way or another we're going to find out.
