Ethereum proposed to use blockchain technology not only for maintaining a decentralized payment network but also for storing computer code that can be used to power tamper-proof decentralized financial contracts and applications. Bitcoin Bitcoin was launched in January It introduced a novel idea set out in a white paper by the mysterious Satoshi Nakamoto —Bitcoin offers the promise of an online currency that is secured without any central authority, unlike government-issued currencies.

There are no physical bitcoins, only balances associated with a cryptographically secured public ledger. Although Bitcoin was not the first attempt at an online currency of this type, it was the most successful in its early efforts. As a result, it has become known as the predecessor to virtually all cryptocurrencies that have emerged over the past decade. Over the years, the virtual, decentralized currency concept has gained acceptance among regulators and government bodies.

Ethereum Blockchain technology is being used to create applications that go beyond just enabling a digital currency. Launched in July , Ethereum is the largest and most well-established, open-ended decentralized software platform. Ethereum enables building and deploying smart contracts and decentralized applications dApps without downtime, fraud, control, or interference from a third party.

To accomplish this, Ethereum comes complete with its own programming language that runs on a blockchain. The potential applications of Ethereum are wide-ranging and are powered by its native cryptographic token, ether commonly abbreviated as ETH. In , Ethereum launched a presale for ether, which received an overwhelming response.

Ether is used mainly for four purposes: It is traded as a digital currency on exchanges, held as an investment, used to purchase goods and services, and used on the Ethereum network to pay transaction fees. Key Differences While both the Bitcoin and Ethereum networks are powered by the principle of distributed ledgers and cryptography, the two differ technically in many ways. For example, transactions on the Ethereum network may contain executable code, while data affixed to Bitcoin network transactions is only used to record transaction information.

The Bitcoin and Ethereum blockchains and networks are different concerning their overall aims. Bitcoin was created as an alternative to national currencies and thus aspires to be a medium of exchange and a store of value. Ethereum was intended as a platform to facilitate immutable, programmatic contracts and applications via a global virtual machine.

Proof of Work vs. Proof of Stake Bitcoin uses a consensus protocol called proof of work PoW , which allows the network nodes to agree on the state of all information recorded and prevent certain types of attacks on the network. In September , Ethereum moved to proof of stake PoS , a set of interconnected upgrades that will make Ethereum more secure and sustainable.

To address issues regarding scalability, part of the transition to proof of stake is sharding, which will continue to be addressed through A major criticism of proof of work is that it is highly energy-intensive because of the computational power required. Proof of stake substitutes computational power with staking—making it less energy-intensive—and replaces miners with validators, who stake their cryptocurrency holdings to activate the ability to create new blocks.
