Pizzap VoiceNFT on Plian blockchain


How to describe an audio file stored online, so that those who need it can quickly confirm that the file is accurately what you need in thousands of files through this description. For example, how to distinguish Musk’s voice from Trump’s voice through different words. It’s the meaning of MetaData.

MetaData refers to the characteristics, color, shape, size and source of stored objects. We can simply understand MetaData as the smallest data unit. Data in any file system is divided into data and MetaData. Data refers to the actual data in ordinary files, while MetData refers to the system data used to describe the characteristics of a file.

There are 2 ways of MetaData management: centralized management and distributed(decentralized) management:

  1. Centralized management means that a node in the system is specially responsible for MetaData management, and all MetaData is stored on nodes. Before all clients request files, they must first request MetaData from the managers.

  2. Distributed(decentralized) management means that MetaData is stored in any node of the system and can be migrated dynamically. The responsibilities for MetaData management are also distributed to different nodes.

Most cluster file systems adopt centralized MetaData management. Because centralized management is simple to implement and easy to maintain. Due to the current storage limitations of Ethereum, most projects only store MetaData offchain. The easiest way to store MetaData exists on a centralized server somewhere, or in addition to distributed storage.

More and more developers, especially in the field of digital art, are using IPFS to store offchain MetaData. VoiceNFT creators that use Pizzap can now mint NFT generating immutable MetaData that uses IPFS content addressing + provable & decentralized storage, too.

IPFS is a global, peer-to-peer distributed file system. The goal of IPFS is to supplement (or even replace) HTTP storage, which currently dominates the Internet, and connect all computing devices with the same file system.

To uniquely attribute and identify each file, it uses a content identifier (CID). Think of it as a generic content fingerprint, in which a specific hash can only be linked to a specific working part. Therefore, any data change to the image will result in a different CID generated. The unique identification function of CID is very consistent with the unique storage requirements of NFT.

Another option is to directly authorize the community to maintain data through DataDAO and Oracle, which combines IPFS verifiable storage with cross chain smart contracts. Pizzap’s goal is to move in this direction to further promote the persistence of online digital works. Although there have been many actions, it is important to remember that NFT is new. We need to keep adding traditional resouces in through delicate combinations.

At present, Pizzap is building a community to form a story environment in which members automatically manage content. At the same time, it is also contacting several sound labs and several AI labs to migrate the traditional content creation ability and resources. However, all of these are only the transmission forms of content in Web 1.0 & Web 2.0, which is maneged in a centralized way. However, the creation of content and the storage of content data, including MetaData, should mainly be decentralized and distributed.
