RChain registry interaction

rchain-registry.md

new register(`rho:registry:insertArbitrary`), out(`rho:io:stdout`), myContract, ret in {
  contract myContract(arg1, arg2) = { out!(("These are the args: ", arg1, arg2)) } |
  register!(bundle+{*myContract}, *ret) |
  for (@urn <- ret) {
    out!(("My contract is located at this URN: ", urn))
  }
}

To look up the contract at the id in a different deployment:

new lookup(`rho:registry:lookup`), ret in {
   lookup!(`rho:id:ugft58531rdrupt66fux6he4ki71o9bp4nzcede5jbfeiwcktp3g35`, *ret) |
   for (myContract <- ret) {
     myContract!(1, 2)
   }
}

Storing a contract at a public key is similar:

new register(`rho:registry:insertSigned`), out(`rho:io:stdout`), myContract, ret in {
  contract myContract(arg1, arg2) = { out!(("These are the args: ", arg1, arg2)) } |
  register!(<public key>, (<nonce>, bundle+{*myContract}), <signature>, *ret) |
  for (@urn <- ret) {
    out!(("My contract is located at this URN: ", urn))
  }
}

The nonce is an integer; to replace what is stored at the public key, increase the nonce. The signature is over the tuple (, ).
