Since 2007. At some point I became convinced there was a way to do this without any trust required at all and couldn't resist to keep thinking about it. Much more of the work was designing than coding.

Users can link identity.

See Section 10 of my Whitepaper.

At no point is identity removed from bitcoin. Rather, in the new privacy model of bitcoin identities are exchanged where needed between individual parties. Today, there are laws for cash and the transaction of money using cash. Because you're using cash does not mean that you can avoid recording identity.

Know your customer requirements, customer due diligence and anti-money laundering laws all cover cash.

Whether it is a single transaction or multiples, where the value is €10,000 or more, the person transacting would require registration as a high-value dealer.

This even applies if you make instalments or payments on account. Bitcoin is a cash money system. Consequently, all of the money laundering regulations concerning cash will apply.

If you're receiving small amounts of money, not only micro-payments but even if you're running a coffee shop or restaurant, there will be no requirement to register as a high-value dealer. A real estate broker offering commercial leases could easily exceed this amount and thus have to require registration.

The majority of exchanges made using bitcoin will not require registration. Any exchange or custodial service will require registration. Local bitcoin and related organisations will require registration. When people go wrong is to think that normal everyday coffee shops and related organisations will require registration.

The need for trust is mitigated using registered identity based keys and hierarchies of linked keys.
