Enterprise Ethereum Enterprise Ethereum refers to customized software and networks based on Ethereum that are created for private corporations and businesses. These networks are permissioned, meaning enterprise clients retain control over the architecture, the validators, and the users. Morgan, Mastercard, and Microsoft — all of whom are experimenting with private versions of Ethereum for enterprise purposes. Morgan and more than banks use a version of Enterprise Ethereum to run an inter-bank payment network.
The Covantis initiative, set up by a group of institutions in the commodity industry, uses Enterprise Ethereum to run a post-trade execution platform for agricultural shipping transactions. Non-Fungible Tokens on Ethereum Non-fungible tokens NFTs are unique, indivisible, and provably scarce digital assets that are useful in gaming, art, and ensuring the provenance of luxury goods.
NFTs have attracted an increasingly mainstream audience to cryptocurrency and blockchain technology. Stablecoins Stablecoins are cryptocurrency tokens pegged to another asset, typically a fiat currency. For example, there are stablecoins backed by fiat currencies like the U. Additionally, some stablecoins are backed by a balanced basket of major cryptocurrencies. Stablecoins are used as a reliable store of value in the cryptocurrency ecosystem, a hedge against price volatility for crypto traders, and as a stable, global currency for people whose local fiat currency is devalued due to economic or political instability.
Today, many crypto exchanges have their own stablecoins. Decentralized Finance Decentralized finance DeFi is the newest innovation to see an avalanche of use and growth on Ethereum. DeFi platforms are reinventing traditional financial products and services, adding programmable, decentralized, and censorship resistant features to create brand new financial products. For example, DeFi platforms offer peer-to-peer P2P borrowing and lending , interest on crypto holdings, decentralized exchange DEX mechanisms, stablecoins, and composable features that maximize passive earning opportunities.
Industries from healthcare to entertainment to real estate are creating novel tools on the protocol to enhance efficiency, trust, and democratize access to various types of services. For example, Ethereum provides an ideal solution for managing royalties in the music industry by distributing tokens that represent ownership rights that facilitate automated and seamless distribution of royalty payments. Ethereum projects working in the music industry include Ujo, Mediachain, and the Open Music Initiative.
In the massive global remittance industry, cross-border payments can be sent directly, quickly, and inexpensively by using a P2P protocol like Ethereum. For example, companies such as Everex, Abra, and BloomX use blockchain technology to cut out various intermediary banks that charge fees for currency exchange.
Meanwhile, end consumers can rest easy knowing that the products they purchase are in fact genuine. Everything from luxury goods to organic foods are tracked and traced with the Ethereum network. Additionally, through use of cryptographic methods, Ethereum ensures secure information sharing, which is essential for the transfer of sensitive data like medical records and identity information.
Finally, Ethereum tokens democratize access to products that were once beyond the reach of many. What You Need to Know Smart contracts are self-executing lines of code with the terms of an agreement between buyer and seller automatically verified and executed via a computer network. Nick Szabo, an American computer scientist who invented a virtual currency called "Bit Gold" in , defined smart contracts as computerized transaction protocols that execute terms of a contract.
Smart contracts deployed to blockchains render transactions traceable, transparent, and irreversible. How Smart Contracts Work Smart contracts were first proposed in by Nick Szabo, an American computer scientist who invented a virtual currency called "Bit Gold" in , fully 10 years before the invention of bitcoin.
In fact, Szabo is often rumored to be the real Satoshi Nakamoto, the anonymous inventor of bitcoin, which he has denied. Szabo defined smart contracts as computerized transaction protocols that execute terms of a contract. He wanted to extend the functionality of electronic transaction methods, such as POS point of sale , to the digital realm. In his paper, Szabo also proposed the execution of a contract for synthetic assets, such as derivatives and bonds.
Szabo wrote: "These new securities are formed by combining securities such as bonds and derivatives options and futures in a wide variety of ways. Very complex term structures for payments can now be built into standardized contracts and traded with low transaction costs, due to computerized analysis of these complex term structures.
