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.
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.
Bitcoin: Bitcoin is the first and most notable decentralized digital money. It uses a consensus algorithm called Proof of Work (PoW) and is primarily used for digital currency transactions.
Ethereum: Ethereum is a blockchain platform that is designed to be a decentralized world computer. It allows developers to create and deploy decentralized applications (dApps) and smart contracts. It uses a consensus algorithm called Proof of Stake (PoS) and its native programming language is Solidity.
EOS: EOS is a blockchain platform that is designed for high-performance decentralized applications (dApps). It uses a consensus algorithm called Delegated Proof of Stake (DPoS) and its native programming language is C++.
Corda: Corda is a blockchain platform that was specifically designed for financial services. It is an open-source platform that is focused on privacy and interoperability, it allows for the creation of private networks and it uses a consensus algorithm called Practical Byzantine Fault Tolerance (PBFT)
Finance: Blockchain technology is being used in the financial industry to create decentralized financial systems, which can help to increase security and reduce costs. For example, blockchain-based decentralized exchanges (DEXs) allow users to trade cryptocurrencies without the need for a centralized intermediary. Additionally, blockchain technology is also being used to create decentralized lending and borrowing platforms (DeFi), which can help to increase access to financial services for individuals and small businesses.
Production network on board: Blockchain innovation can be utilized to make straightforward and proficient inventory network frameworks. For example, Walmart is using blockchain technology to track the origin of food products, from farm to store, to improve food safety and reduce waste. Additionally, Maersk, the world's largest shipping company, is using blockchain technology to create a digital shipping platform that can help to reduce costs and increase transparency.
Healthcare: Blockchain technology is being used in the healthcare industry to create secure and efficient healthcare systems. For example, MediLedger is a blockchain-based platform that is being used to track the supply of pharmaceuticals, helping to reduce counterfeit drugs and improve patient safety. Additionally, blockchain technology is also being used to create secure and transparent electronic medical records (EMR) systems that can help to increase patient privacy and reduce administrative costs.
Real Estate: Blockchain technology is being used in the real estate industry to create secure and transparent property-buying and selling systems. For example, the Republic of Georgia has implemented a blockchain-based land registry system that allows for the digitization of property deeds and property transactions, increasing transparency and reducing fraud.
Energy: Blockchain technology is being used to create decentralized energy trading systems, which can help to increase the efficiency of the energy market. For example, Grid+ is a blockchain-based platform that allows individuals and businesses to buy and sell energy directly, without the need for intermediaries.
