The universal ability to connect the blockchain to the real-world information is the core goal of the ZK-Oracle. In order to achieve this goal, the barriers between the blockchain and the real world must be broken, and a bridge between the blockchain and the real world must be established. In the real world, the Internet has developed rapidly in the past two decades, and cloud deployment technology has also made it possible to interconnect global websites and applications. On the other hand, in the blockchain world, as the technology of the blockchain becomes more mature and the demand for application implementation is increasing, people gradually realize that the single-chain system is difficult to meet the huge data requirements, and the single-chain risk is too high, the multi-public chain ecosystem has exploded. However, the current cross-chain technology between different blockchains is not mature, or even just in its infancy.
The oracle realizes the data interaction between the blockchain and reality, while the cross-chain realizes the data interaction between the blockchains. In essence, the cross-chain feature is a subset of the oracle and is directly related to the performance of the oracle. As to ZK-Oracle, cross-chain feature is a key feature to improve ZK-Oracle's universality, and it is also the key goal of ZK-Oracle's long-term technology strategy. In the technical plan, although ZK-Oracle was originally created based on SERO, it will additionally optimize the structure based on Polkadot's underlying architecture- Substrate, so that after the Polkadot mainnet is online and the functions are complete, it can better migrate to the cross-chain underlying Substrate architecture, and use Cumulus (a plug-in on the Substrate architecture) to deploy Parachain as soon as possible. Parachains belong to Polkadot's external system and are important way for Polkadot to interact with other blockchains. In Polkadot's system settings, there are two ways to interact with other blockchains: through Polkadot's native parachain, or through a relay chain. Among the two methods, the native parachain based on Polkadot has more advantages, since it can call faster cross-chain mechanisms and is more secure (parachains can share security with Polkadot).
The ZK-Oracle node can complete the seamless connection between the blockchain and the real world. No matter what blockchain, no matter what equipment and system in the real world, it can connect to ZK-Oracle for data interaction.
NFT, or Non- Fungible Token, represents the ownership of a unique item or asset on the blockchain. Unique corresponds to the word non-homogenization, which means uniqueness and rarity. At present, most transactions on the blockchain are homogenized FT (Fungible Token). There is no difference between them, and the same number corresponds to the same value. Taking BTC as an example, every BTC is the same, and any BTC can be exchanged with other BTC under the premise of ignoring transaction consumption. Compared with FT, each individual of the same type of NFT is unique and different from each other.
The distributed idea of the blockchain is highly compatible with the attributes of NFT, and it is an excellent medium for displaying and trading NFT assets. Once the assets are recorded on the chain, all processes are open and transparent, preventing forgery and transaction fraud. In addition, global on-chain transactions can greatly improve asset liquidity and asset value, and improve transaction efficiency. Theoretically speaking, NFT can conveniently distinguish the value of virtual non-concretized assets and determine the ownership, and can also help all non-homogeneous real and concretized assets (such as land, art, etc.) digitize on-chain to achieve the same effect. Virtual assets, but in terms of real assets, due to the problem of data fragmentation between the real world and the chain, the current tokenization of real assets is not satisfactory, and the development of the NFT ecosystem has also encountered bottlenecks.
In the long-term technical strategy, ZK-Oracle will be committed to solving the problem of interaction between NFT and the off-chain environment, optimizing the on-chain and off-chain connectivity, and promoting asset tokenization and NFT ecosystem construction. Imagine a scenario where all assets can be tokenized. Whether it is an animation IP, non-concretized virtual products such as games, or physical objects in the real world, or even humans themselves, they can be used in the form of data by oracles and become digital token assets. Taking animation IP copyright as an example, considering virtual assets, it is possible to produce a limited number of NFT tokens for popular animation or popular animation characters for trading and collection, it is also possible to tokenize the popular animation IP or even the authorization of a certain character and set the automatic burn period, purchasing the Token means having the right to use the animation character or the IP of the work within the burn period. From another perspective, considering real assets, such as the official limited-edition toys launched by anime and rare figures, they can all become NFTs for trading and circulation between users/collectors.
The construction direction of the NFT ecosystem is mainly the dynamic data capture and intelligent creation of the NFT, and cross-chain NFT standard access to enrich the NFT ecological content and increase the ecosystem vitality. By developing ZK-Oracle's node ecosystem and optimizing and upgrading ZK-Oracle's off-chain event monitoring function, ZK-Oracle can capture the dynamic changes of real events, automatically upload relevant data to the chain, instantly create NFTs and support P2P transactions. Taking the NBA as an example, if a player achieves a triple-double or lore in a key game, the off-chain network will promptly pass the message to the on-chain smart contract and automatically create a limited-edition virtual card. In addition, ZK-Oracle's cross-chain interaction functions can also give it compatibility with different NFT standards on various blockchains, support the integration of the same type of attribute NFT worldview, and promote cross-chain trading of NFTs.
