Salary Essay: Today, I will talk about a currency that investors in the currency circle are more optimistic about

U.S. retail investors are more bullish on Cardano (ADA) than Bitcoin, according to an investor sentiment survey released by crypto trading brokerage Voyager Digital. Meanwhile, Bitcoin whales are aggressively “buying the dip.”

Cardano is a cryptocurrency network and open-source project designed to run a public blockchain platform for smart contracts. ADA is the token of the Cardano project.

The survey found that 31.8 percent of investors surveyed said they were “most bullish” on Cardano, compared with 22.2 percent who were bullish on Bitcoin. The third and fourth places are Ethereum and Polkadot, with 12.2% and 6.3% respectively.

Last month, Cardano hit an all-time high of $1.48, making it the third-largest cryptocurrency by market capitalization. Here, many investors may not know much about this project. Let me briefly introduce you here. The problem that Bitcoin needs to solve is that when two people have a transaction, they need to verify it with a centralized organization. But transactions are never as simple as one person transferring money to another, and there is often a story behind it. For example, a person may ask another person to do something for him, after which he will pay the person a sum of money. And that's the contract. Ethereum is a programming language that people can use to implement the contracts we need to do, that is, smart contracts.

The current cryptocurrencies all have problems of scalability (Scalability), interoperability (Interoperability) and sustainability (Sustainability). The philosophy and vision of Cardano (ADA) is to solve these problems.

network bandwidth

Network bandwidth refers to the network resources required by the data carried in the transaction for network communication. When the scale of this blockchain becomes larger and larger, the network bandwidth we need will also increase. In fact, it is impossible for us to achieve that every node of the blockchain can support all nodes to communicate with each other. all communications.

To solve this problem, Cardano adopts RINA. RINA, Recursive InterNetwork Architecture. I don't know the architecture very well, so I can only speak roughly. It should be an architecture similar to TCP/IP, which can make the communication between nodes very naturally like inter-process communication (IPC), so that we can naturally carry out large-scale communication.

The amount of data

The infinitely growing amount of data may be the most difficult problem to solve, but in fact, not everyone wants to know all the data. For example, when a person has a transaction with another person, they don't need to know other people's Data, all you need to know is that the context of the party that needs to transfer funds is legal and correct.

So we will need some technologies like pruning, subscription and compression, so that each user generally only needs to save the data they have to save. Generally speaking, it is a concept of partitioning (Partitioning), which means that the user does not actually have the data of all nodes, but saves the data of one block (chunk) of the blockchain.

In terms of compression technology, Cardano will also involve SideChain technology. Through the side chain, we can make those very small data blocks connected together in the form of two-way binding, so that they have a high level of security and correctness.
