TON Decentralized Name Service (DeNS)

Key Features

• True TIP-2, infinity amount of subdomains and levels
• Add new top level domains(root domains) with SMV interface
• Buy domains at Auction
• Instant buy Domain Name for short period with fixed price
• Reselling subdomains of your domain
• Gas managing, no need to replenish certificates
• Build and tests with Github Actions(broken with last update(0.38), will be fixed)

Domain and subdomain registration options

Each Name certificate has own type of registration child domains. Registration type and other parameters can be changed by an owner of certificate.

Child certificates can be issued no longer than the expiration period of the parent certificate.

enum RegistrationTypes { OwnerOnly, Auction, Instant }
function setRegistrationType(RegistrationTypes newRegistrationType) external;

Auction

One Auction contract will be deployed one per domain for a buy. All bids are made blindly by sending hash of (bid + salt). Then, during the confirmation phase, participant need to send the entire bet and salt.

The highest bid wins, but participant need to pay for the domain according to the size of the second bid.

Anyone can create Auction for child domain by sending specific request to NIC if domain available or expiration < 28 Days.

function registerNameByAuction(string domainName, uint8 durationInYears, uint256 bidHash) external;
function setAuctionDeposit(uint32 auctionDeposit) external;

To prevent bet spam, it is possible to set the size of the blind bet.

Instant Buy

Option to buy domain right now for short period of time avoiding the auction. Max duration and price installed by owner.

function registerInstantName(string domainName, uint32 durationInSec) external;
function setInstantBuyPrice(uint128 instantBuyPrice) external;
function setInstantBuyMaxSecDuration(uint32 instantBuyMaxSecDuration) external;

Create by Owner

New certificates can be issued by an owner.

function registerNameByOwner(string domainName, uint32 expiresAt) external;

ton-dens's Issues

Create Actions for github

• Run local tests
• Run on-chain test (local node)
• Build using specific version of sol2tvm compiler
• Deploy package with compiled contracts to github repo

Write documentation

• Step-by-step instructions for building and deploying by hand
• System workflow
• Interfaces description
• ...
• Composite structure diagram
• Sequence diagram
• Deployment diagram

Implement address resolver in tonos-cli/SDK

Implement Interfaces for all contracts

• Auction
• DeNS Root
• NIC
• DeBots

Create local tests

Create scripts(may be python) for running only specific contract methods and check for results

TestSuite4 - python framework for testing SMC

Test Cases:

• will be added in future

Create DeBot

• DeBot Specifications
• New DeBots Repo
• Old DeBots Repo

Create scripts for deploy contracts

Create on-chain tests

Create js scripts using SDK for running different cases and contracts usages right in blockchain(devnet, local node)

Test Cases:

• will be added in future
