Recently, my friend fell into a huge pit and couldn't sleep for several days—while driving on the highway, the tire was punctured and the paint was damaged. He found a car repair shop, paid a 1000 yuan deposit, but the other party only replaced a part and then claimed they needed more money, subsequently stopping work.
Watching him crouch beside the broken car and sigh, I suddenly realized: as car owners, we always pay money and trust in advance for repairs and maintenance, but the trust we place is often the most easily betrayed.
But today I want to tell everyone that there has long been a way to ensure that these auto repair scams can't escape—it's blockchain + smart contracts.
In simple terms, it is to hand over the maintenance agreement and costs to code management, rather than relying on verbal promises from people. You first deposit the advance payment into the smart contract; the money does not go directly to the other party's account but is securely locked. Once the repair shop completes clear milestones like sheet metal painting and engine repairs, you confirm on-site that everything is fine, and only then will the corresponding proportion of the money be automatically transferred.
What if the other party is perfunctory halfway through? The code will directly refund the remaining money back to your account, with no need to argue with them or look for consumer protection channels everywhere. You don't need to trust the verbal guarantees of the repair shop; you only need to trust the rules written on the chain—after all, code does not lie, nor will it run away.
There are now mature tools doing this: one $NIGHT is an on-chain signing tool, the maintenance agreement goes on-chain once signed, and no one can change or delete it, not even find an excuse to cheat; the other is a smart profit-sharing agreement, specifically designed to solve the trust issue of 'whether to pay first or repair first.'
Of course, this set of solutions is mainly used by enterprises now, and for ordinary people, the operational threshold is indeed a bit high; you need to understand the basics of wallets and on-chain interactions first. But at least we know: in the future, when encountering large transactions like auto repairs, maintenance, and modifications, we will no longer be passively accepting the situation. #night
