# RNS Improvements
[TOC]
## Contracts
1. join resolver and registry repositories.
2. export types from typechain to npm.
3. clean up repos and move legacy to another one.
4. which organization should we use for this? (rnsdomains or rsksmart or both?)
5. [rns-registrar](##rns-rskregistrar)
* Update dependencies node v12
* solidity v0.5.3
* Immprove natSpec (missing functions and typos)
7. [rns-registry](##rns-registry)
* Update dependencies node v12
* solidity v0.5.0
8. [rns-resolver](##rns-resolver)
* Update dependencies node v12
* solidity v0.5.0
10. [rns-reverse](##rns-reverse)
* Update dependencies node v12
* solidity v0.5.3
## SDK
1. use contract types generated with typechain.
2. fix github issues
## UI
1. use the new rns-sdk instead of the rns-js
2. Update dependencies to be compatible with lastest version of npm(now v12)
# Architecture
## rns-rskregistrar
https://github.com/rnsdomains/rns-rskregistrar
Node v12, truffle
Solidity 0.5.3
* All tests passing (523)
* Remove empty `Dummy.sol`.
* Immprove Natspec, missing functions and typos.

### Videos summary
#### Layers
- Protocol: Smart contracts
- Libraries: Tools for developers
- Resolving
- Updating records (similar to [DNS records](https://www.cloudflare.com/learning/dns/dns-records/))
- SDKs: Tools to administrate domains
- Edit records by owner
- Registration (zones): Registration model for each zone. Paid in RIF.
- RNS Manager(npm v12 or dependency conflicts): [DApp](https://github.com/rsksmart/rns-manager-react) with SDK [old version](https://github.com/rnsdomains/rns-js) (web3.js), [new version](https://github.com/rsksmart/rns-sdk)(ethers.js).
* https://testnet.manager.rns.rifos.org/
* https://manager.rns.rifos.org/
#### Search for subdomain
##### [Registrar](https://github.com/rnsdomains/rns-rskregistrar)
Owns and sell subdomains
- Queries .rsk
- Asks the [price](https://github.com/rnsdomains/rns-rskregistrar/blob/b20ce07dce3290de0b0bedcc8c8ba3aca30ea039/contracts/NamePrice.sol#L18) to purchase a subdomain on their zone
###### 1. Sealing (First tx):
To prevent front running, same as [ENS](https://app.ens.domains/name/lancenn.eth/register):
* Submiting a seal pruchase (submiting the hash)
* Submit the actual domain (after 1m)
**Note:** Stores in *LocalStorage* data from the first tx, this way even if loses connection it won't lose the first tx. Every 10 seconds asks to the smart contract if **can I unseal.**
###### 2. Unsealing (Second tx):
* Sends the hash and the **sealing secret**( duration(# years), salt, hashOfthe Domain)
* Unsealing -> sais exactly the domain and registered.
**Privacy problem:** The domain it's being saved on the blockchain ex: 'lancenn' this string its beeing saved, even submiting a hash could be crack. If you don't want to share your on chain balance or history, then the domain should not be created for that account.
#### Admin domain(NFT)
##### Registrar
* Renew ownership
* Transfer ownership
* Set controller: Controller is the address that can update records
* NFT owner: can update Controller address
##### Records
* Update addresses
* Decentralized URL
* Multicoin addresses
