UDAP BLOCKCHAIN : TOKENIZE EVERYTHING

Good day everyone,i would be writing further about the UDAP platform,click on this link in order to have an overview of the last article i wrote on UDAP PLATFORM https://steemit.com/ico/@adelekejustin01/introduction-to-udap-tokenize-everything .Today i would be writing further on;

SINGULAR
An EVM smart contract framework that provides a standard model of tokenizing non-fungible assets. It contains a definition of contracts for singular item, a wallet for these items, interfaces to other token standards such as ERC20 and ERC721, and primitives for decentralized trading of singular assets.

Our basic asset contract singular and the design

1. A piece of asset is uniquely associated with a smart contract account. The account is the home for the asset. People can easily scan the information about this token through public services like Etherscan.

1. The owner of the Singular token must be another smart contract account, named ISingularWallet. There is no direct way for EOAs to own Singular tokens. This design is largely in the same direction of Ethereum’s account abstraction model (discussion)that might be deployed in a future version of Ethereum.

1. It should support push ownership transfer and pull ownership transfer patterns. In so called one-step transfer, the current owner can pass an offer of the token ownership to the receiver account and the receiver account can choose to accept or reject the offer in the same transaction. In a two-step ownership transfer, however, the current owner reserves the token for the next owner in a transaction. The address of the token is passed to the receiver out-of-band. The receiver issues a separate transaction to accept the offer, once it determines that the offer is in its interest.

1. Operators. The ISingularWallet account can assign operators to help with ownership transfers. Having an operator to manage the asset token on the owner’s behalf is a pattern that has been accepted by some other proposals, such as ERC721 and ERC777. People have found it convenient in handling token trading. The current token owner can appoint an operator for the next ownership change. But setting the operators on the token directly is polluting the token interface.

1. Timelock. When an owner make an offer of ownership to someone else by calling the approveReceiver() function, there is a required argument for expiry time, during which period the receiver can take the ownership at will by invoking accept(...)on the token, which will in turn send a notification to the previous owner for it to any state update it wants, or even chain to another action. A critical design is that the owner cannot change his mind during the offer period. This is essentially a time-lock for the transaction. In contrast, neither ERC20 nor ERC721 or any of their derivatives offers built-in time-locks for ownership trading.

1. Token swapping and token sale is implemented with an intermediate TradeExecutor, which is a stateless contract that deployed at a well-known address and be trusted by Singulars for ownership management.

1. Adapters have been built to wrap tokens in ERC20 and ERC721 as tradable Singulars. This enables building decentralized asset exchange in a very straightforward way.

UDAP MIDDLEWARE
UDAP is a “layer two” solution to non-fungible asset lifecycle management, search and trade(including some common trading models like buy and sell, rental, auction, pledge, etc.). With this proposed decentralized middleware network, non-fungible assets can be defined, registered, verified, tracked and traded using an ERC721-compatible on-chain asset model. Complex operations like auction and search are routed to off-chain service nodes, however, transactions are still anchored by on-chain consensus algorithms.

Application developers no longer need to code with low-level web3 APIs and specific storage and messaging APIs. The middleware provides a coarse asset-oriented APIs and off-chain solutions (like state channel and off-chain search) that expands transaction capacity and enables immediate finality.

SOLUTION

1. Valuable decentralized features that do not require heavy investment in blockchain technologies.UDAP defines convenient APIs for traditional vertical applications. This allows them to integrate with blockchains. An added benefit to application developers is that a deep understanding of blockchain and decentralization technologies is not required.

2)Fast, cheap and secure integration with public blockchains, without specific lock-in.
UDAP implements State Channel technology to solve some of the most challenging issues with developing and running Blockchain-based applications. State Channel technology provides high scalability, low cost, privacy protection and immediate responsive.

3)Application Wallet with in-app currency and Smart Contracts that provide asset life cycle management, trading (including some common trading models like buy and sell, rental, auction, pledge, etc.) and search capability.
