Blockchain and Crypto Assets
Blockchain and Ether are important components of the metaverse. Ether has a number of key criteria, each of which will play a unique role in building the metaverse. These key standards include：
ERC- 20: ERC- 20 is a technical standard for all smart contracts used for token implementation on the Ether blockchain. This standard applies to the currency in the similar specific world, which is fungible and interchangeable with other similar currencies.
ERC- 721: This standard applies to non-fungible tokens. According to the ERC- 721 standard, each item is unique - think of it as a painting or other unique digital collection or something like that. Because the item is unique, it comes with a programmable smart contract to account for the additional benefits it carries. The item can also be sold to another party.
TOKENS (NFT) By now, you have seen the word, which is tokens(SPACEE) , used frequently in this paper. A token is a unit of data stored on a digital ledger, and understanding these tokens is critical to fundamentally understanding how consumers will interact with each other in the metaverse, and how brands will interact with users. There are two types of tokens, Fungible and Non- Fungible.
Fungible items, such as digital currency tokens (e.g. Bitcoin), can be exchanged with other tokens of the same type. Since Open World uses blockchain technology, users can trade assets between different worlds and literally own their items in the virtual world on the blockchain. This concept of real ownership is crucial to understanding digital goods.
However, NFT is an irreplaceable token that is protected on the blockchain. Non-Fungible means that the digital item is completely unique, exclusive, but also digital. Because it is on the blockchain, it can also carry additional rights or entitlements. Because consumers have access to rights in both the virtual and real worlds, NFT will have a profound impact on how brands should think about creating long-term and direct relationships with consumers.
inance Smart Chain (BSC) is the main chain of the dual public chain mechanism of Binance, the world's largest digital currency exchange, and can be seen as a parallel Blockchain to the Binance Chain, currently serving the De Fi and NFT ecosystems. BSC has Smart Contracts functionality and is compatible with the Ether Virtual Machine (EVM). It is designed to maintain the high throughput of the whole Binance Chain while introducing smart contracts into its ecosystem.
