Make the faucet register users on-chain (instead of Redis)

[moul]

Objective

Our goal is to pivot the user registration mechanism to a fully on-chain system, phasing out the reliance on off-chain storage methods, specifically Redis. Transitioning to this approach presents the following benefits:

• Transparency & Decentralization: Emphasizing on-chain processes enhances transparency and decentralization, pushing the boundaries of what's possible with blockchain technology.
• Ensuring Account Uniqueness: On-chain registration guarantees that each token is linked to a distinct account. This curtails any chances of malpractice such as associating a single token with numerous manually generated accounts.
• Performance Enhancement: Steering towards on-chain registration limits realm interactions to genuine participants. This safeguards realm performance, preventing a potential overload from a vast number of addresses.
• Facilitated Dynamic Whitelisting: Other contracts can access the registration realm, enabling dynamic whitelisting. This offers scalability for ensuing blockchain activities and applications that mandate a curated list of approved participants.

Through this on-chain transformation, we further our commitment to harnessing the true capabilities of blockchain, ensuring an efficient and equitable registration experience for our competition.

Implementation Strategy

1. Faucet Procedure Alteration:

   • Instead of the faucet executing a Send transaction to dispatch tokens to a designated address, it should instead be programmed to trigger an on-chain player registration process. This can be achieved with the following call: -pkgpath r/demo/register -func RegisterPlayer(addr, token) -send XXXugnot.

2. Registration Contract Functionality:

   • The contract located at r/demo/register has a twofold responsibility:
     • Firstly, it must verify the uniqueness of the account, ensuring no previous claims exist for the given address.
     • Post verification, the contract should record the registration details and subsequently disburse the tokens to the provided address using the capabilities of the std.Banker module.

Just on -func RegisterPlayer(addr, token), how do we ensure the player use the same token as it's provided in mailchimp ?
