A while back I wrote a post about the Melville Deli, a Long Island business that accepts bitcoin.

Tomorrow at 5:00pm Simon, owner of the deli, is sponsoring a bitcoin meetup. If any stackers are in the area, you should definitely stop by:

I'm planning on hosting a meetup at the deli next Friday the 17th at 5pm. Sandwiches, beer and possibly steaks on me. Feel free to join. Just give me a heads up if you want steak. Got a couple bitcoiner buddies coming already, should be a good time.

This criticism of Robin's bridge model seems to incorrectly state that verifiers can burn user funds in step 8. That is not my understanding of Robin's model, I believe that if the prover does not process a withdrawal, the verifiers can burn some funds that the prover himself put up as a kind of stake to dissuade dishonest behavior, but user funds do not get burned, they simply move to a new m-of-m multisig controlled by the remaining verifiers.

One of them becomes the new prover and must process the withdrawals now otherwise they lose their own stake and the cycle repeats until one of two things happens: either some verifier processed the withdrawals properly when it was their turn, or all user funds become the sole property of the last verifier, locked to a 1-of-1 where he or she is the only remaining keyholder.

At that point, this final verifier can simply send the users their money without hindrance. But if he or she is dishonest, users are out of luck, the last verifier can run off with all user funds if no previous verifier could or would perform the withdrawals honestly. (This is largely why you must always trust at least one verifier to be honest, in Robin's model.)

Also worth pointing point: my unisob bridge model is unaffected by this criticism. The prover sources the funds to perform a withdrawal when the user first deposits money to the bridge, and every depositor gets to withdraw up to the amount in their own individual contract with the prover. If the prover is unable to source sufficient funds, the would-be depositor simply aborts and never makes their deposit.

UN-Offical. But here is the list I threw together.

Ever bought a computer or cell phone?

Why? Why not wait until your money is worth more later compared to the price of that cell phone?

Because you need it.

Before mortgages people bought the amount of house they could afford. Married couples (instead of spending tens of thousands of dollars on a wedding) would buy a house and build a basement that they live in until they can afford to build the rest of the house.

People are living beyond their means. Once I switched completely over to BTC as my money I ended my debt and bought my house in cash.
