Do you already have a team of developers you will work with?
No
I will start with the fact that good tamper proof package may come with additional costs people may not want to pay for.
I don't think tamper proof is the only way.
Let's say that there's an issue with package's content and the sender claims he sent everything right, the recipient claims the content is missing/incomplete.
Do you have a good way to find out if it's the sender or recipient lying or any of the "couriers" was skilled enough to steal without leaving traces on the package seals? How will the reimbursement handled?
Though a smart contract on bitcoin that is made before the purchase, in the description that will solve disputes. To know if a package is missing or damaged I hope there is a way, in any case I think we can do like a pool of escrows that will decide, like today is done by bitcoin nodes that check for transactions to broadcast.
Also, how about bitcoin price fluctuations?
I don't think there is a problem here, they overcollateralize like 2x the amount of the package and can get liquidated before having less collateral than package value.
Still on collateral: the couriers will know when a package is expensive, making it a good target for stealing/tampering.
But if they lock an amount of bitcoins they will get punished if they tamper the package, this can be decided by pools of escrows or smart contract. The pool of escrow get a share of bitcoins for their service in case of problems.
Then the income: how you split the shipping price between the couriers? Time and distance are not enough as factors (rush hour, or remote areas are probably more important to take into account).
Based on couriers choosing on price. Then it will be calculated by sender / reciever if they want to get package faster or cheaper.
There is a difference between a Decentralized Marketplace, where the market itself is decentralized but on a centralized network, and a decentralized network. What I am trying to say is that a decentralized market does not necessarily mean that the network will be decentralized. Creating a decentralized network is expensive, slow, and difficult to modify. A decentralized market with all the features above can be created via a distributed network.
Yes but can it be created on bitcoin Layer2? Do they have some type of smart contracts that allow this?
