3rd party mixing services have got to go. How would this mixing work exactly?

There are many other methods of removing 3rd parties in mixing services , This allows one to both remove the third party and do so privately without outsiders knowing.

"Many other transaction types also use the same hash locked pattern, but privacy can be further improved: A ZK-payment can be transformed using the CoinSwap approach where they payer first pays into an ordinary 2-of-2 escrow+refund with the payee. The then would perform the ZK-payment transactions described above externally to the Bitcoin network, and if everything goes through without cheating the payer just signs a 2-of-2 release to pay the payee directly, without disclosing to the network that a hashlocked transaction was used. If the payer fails to release the escrow directly, the payee can just release it by announcing the hashlock and hashlock redeem. "

----------------------------------

Wrapping ones head around these concepts may be tricky at first but using them after the code is written can be so simple that your grandmother can execute a  zk-SNARKs without actually understanding the underlying code. This is going to have far reaching implications that is going to radically effect everyday life. There is a long list of implications and use cases that I could discuss ad naseum, Here are some more-

Hackers or security researchers could sell exploits/bugs with security bounties and privately and securely prove the information is legitimate without compromising their identity and risking litigation from an embarrassed organization.

Securely validate identities without disclosing the details

Authenticate data or passwords without disclosing the secret or password





Soon you can mix and buy your honey puffs in peace. If you can upack that^ Cool

In Cryptocoins I Trust

Criminals will certainly utilize smart contracts, but I do not think it will make much of a difference to they way the system currently works.

A. Someone operates a drug marketplace on the deep web. The government doesn't try to kill TOR, but they just go after the perpetrators.
B. Someone repeatedly scams others on Craigslist. The authorities go after the perpetrator and leave Craigslist alone.
C. A drug lord operates using the US dollar for all his operations. The government doesn't outlaw the use of the US dollar, but instead it goes after the perpetrator.
D. Someone launders money using Bitcoins. The government doesn't shut down Bitcoin, it goes after the money launderer. Much the same the government doesn't kill the numerous other industries that are used for money laundering.
E. A decentralized market has sellers of both legal and illegal goods and services. The government will go after the sellers of illegal goods and services, and leave the other sellers and the market itself alone.
Etc.

As long as the service, such as a cryptocurrency that utilizes smart contracts, is useful for legal reasons, then I think the government will not try to shut the cryptocurrency down. Instead they will go after the criminals themselves. They will only try to shut down or kill a cryptocurrency or decentralized technology that is purely (or mostly) used to break the law.

you have displeased the thought police. Shame on you.

Quote
Some of these "marginal" uses are terrible to consider. Extortion, kidnapping, and even murder
contracts become easier to set up. Extortion, for example, becomes almost unstoppable at the usual
place: the collection of a payoff and/or the spending of the payoff money

Straight from May in 1996. 20 years later and it is finally becoming a reality. Im surprised they took so long- I would have thought the worlds assassins would be an impetuous client. Ignore them at your peril.

Kinda surprised that Assassination Marketplace never took off.

I guess there's still time.

To be honest, I didn't like the UI.

Humans can be so shallow...

Simple and easy to write contracts appear to be sufficient for many entirely digital transactions. But as these systems start to interact with the physical world, there is likely to be a need for greater intelligence and real world knowledge in making decisions. AI systems will be needed to translate information from a wide variety of sensors into precise terms that smart contracts can act upon.

And unnecessary.

Do Smart Contracts enable a wider range of significant new crimes than earlier cryptocurrencies (Bitcoin)? How practical will such
new crimes be? What key advantages/disadvantages do you see?

i think there are in theory alot of possibilities but do not know the tech detail enough about smart contracts but below is what I want to do.

in my country one agency has the monopoly on sports betting.

I and many others like longer term bets eg betting on the outcome of an event say 6 months out eg Formula 1 or the local football league.
the agency will sell a bet 6 months out but if it is to be on sold to someone else it must be sold for its face value ie $20 (as a second hand good) other wise it is creating a new bet which is illegal ie they can take you to court.

say I bet $20 for an expected payout of $200. closer the event my bet looks very likely to 'win" so I might like to sell it for say $100. I make $80 (guaranteed) and the new owner of the betting slip will make $100 if it wins. the bets at that time from the agency might be a payout of only $150 for a $100 bet so the buyer of my bet also gets a good deal by buying my bet.
currently however I would have to sell it to the person for $20 so the transaction does not take place.

can smart contracts make this work so that neither the buyer, seller of intermediary (eg an exchange) can get found or even if found show that what they have done is not create a new bet?

thanks

Example: Assassination of Senator X

Contractor C posts a contract for the assassination of Senator X.
The contract rewards a perpetrator P for commission of this crime.

The contract takes as input from a perpetrator P a commitment (vcc) specifying in advance the details (day, time, and place) of the assassination. To claim the reward, P decommits vcc after the assassination. To verify P ’s claim, Contract searches an authenticated data feed on news to confirm the assassination of Senator X with details matching vcc.
