4. Smart contracts

A brilliant agreement is a PC program that naturally executes the details of an agreement when certain circumstances are met. The concept of smart contracts was first proposed by Nick Szabo in 1994, but it wasn't until the advent of blockchain technology that they could be implemented in a secure and decentralized way.

Smart contracts are used to automate a wide variety of processes, such as financial transactions, supply chain management, and voting systems. They can be used to enforce, verify, or negotiate the negotiation or performance of a contract.

On blockchain platforms like Ethereum, smart contracts are implemented as self-executing contracts with the terms of the agreement directly written into lines of code. The code and the agreements exist over a decentralized network and exist as a shared, replicated and synchronized digital asset. Savvy contracts on Ethereum are written in a programming language called Robustness.

Smart contracts are stored on the blockchain and are executed by the network of nodes. Once a contract is deployed on the blockchain, it is available to be executed by anyone who has the contract address. The execution of smart contracts is secured by the underlying blockchain technology and the consensus algorithm used by the network.

Smart contracts can be used to create decentralized applications (dApps) which run on a blockchain network. These dApps can be used for various purposes like decentralized finance, gaming, social media, and more.

One of the main benefits of smart contracts is that they can automate processes and reduce the need for intermediaries, which can lead to lower costs and increased efficiency. They also provide a high level of security, transparency, and immutability as the terms of the contract are recorded on the blockchain and can't be altered.

In conclusion, smart contracts are computer programs that are stored and executed on a blockchain network. They are used to automate a wide variety of processes and can be used to create decentralized applications. They provide a high level of security, transparency, and immutability and can help to reduce costs and increase efficiency.

5. Decentralized applications

Decentralized applications (dApps) are applications that sudden spike in demand for a decentralized organization, commonly on a blockchain. Unlike traditional centralized applications, dApps do not rely on a single point of control or failure. They are open-source and operate on a peer-to-peer network, allowing for increased security, transparency, and censorship resistance.

The development of dApps typically involves the use of decentralized storage and distributed computing technologies.

Decentralized storage technologies, such as Interplanetary File Systems (IPFS) and Swarms, are used to store and distribute data in a decentralized way. These technologies allow for the creation of a distributed file system where data is stored across a network of nodes, rather than on a centralized server. This can help to increase security, as data is stored across multiple nodes, and can also help to increase availability, as data can be retrieved from any node on the network.

Distributed computing technologies, such as Ethereum and EOS, are used to execute the code of a dApp in a decentralized way. These technologies allow for the creation of a distributed computing network where code is executed by multiple nodes, rather than on a centralized server. This can help to increase security, as code is executed across multiple nodes, and can also help to increase scalability, as the computing power of the network can be increased by adding more nodes.

dApps can be developed using a variety of programming languages, such as Solidity for Ethereum, C++ for EOS or Javascript for TRON. They can also use different consensus algorithms, such as Proof of Work (PoW) and Proof of Stake (PoS) or Delegated Proof of Stake (DPoS).

There are many different types of dApps, such as decentralized exchanges, prediction markets, and social networks. Decentralized finance (DeFi) dApps have been gaining a lot of popularity in recent years, they allow users to access financial services like lending, borrowing and trading in a decentralized way.

In summary, dApps are applications that run on a decentralized network, typically on a blockchain, they use decentralized storage and distributed computing technologies to increase security, transparency, and censorship resistance. They can be developed using a variety of programming languages and consensus algorithms, and there are many different types of dApps, with different use cases.

6. Blockchain platforms
