Proof Of Work Vs Proof Of Stake Which Is Better?

By trennco — In FinTech — October 16, 2020

As reported by CNBC, nine out of ten millennial investors prefer to invest in ways that leave a positive mark. Regardless of government intervention, young investors demand clean investments. The market share of millennials in crypto will only increase with time. Millennials choose environmentally friendly investments 9 times out of 10. Increased transaction throughput and gas fee reductions, however, will not be finalized until 2023.

Anyone who has been in the crypto space even for a short while is familiar with the name Ethereum. The second-largest cryptocurrency after Bitcoin and a blockchain home to numerous NFTs and DeFi projects, Ethereum has branched into digital money, global payments, as well as applications. This centralized control is convenient, but makes them vulnerable to hacks. By contrast, blockchains make everyone running the software—from exchanges to traders in their basement—responsible for updating them. Here also, the transactions are stored in an immutable distributed ledger.


This has also resulted in a shift of Bitcoin miners to other regions around the world, as it becomes more resilient and profitable. The rule prevents multiple chains, each reflecting different versions of history, from existing side-by-side. The longer the consensual version of the blockchain becomes, the more computing power and resources would be needed to — in theory — roll it back.

Blumberg points out that in order for decentralized finance to be viable long-term, the PoS model needs to offer security and speed and allow for real-time transactions. Ethereum’s price dropped modestly in the hours after the completion of ethereum’s merge, offering investors a first view of how the major and long-awaited network change might impact the value of their coins. You don’t need ETH to get started and block rewards allow you to go from 0ETH to a positive balance.

Why Dont Miners Cheat?

Ethereum transactions are built on smart contracts while Bitcoin will implement these in late 2021. Bitcoin and Ethereum are both decentralized projects that work on traceable blockchains. They both feature pseudonymous transactions, which means participants can track transactions but they won’t have the names involved in each deal. Ethereum, which was created in 2015 by Vitalik Buterin, is a cryptocurrency that provides ether tokens. Ether is used to build and deploy decentralized applications whose back-end code is placed in a distributed peer-to-peer network. This is different from a regular application, for which the back-end code is placed in a centralized server.

If you don’t have that kind of spare change on hand, and not many people do, you can join a staking service where participants serve as validators jointly. In a blockchain where participants maintain a shared ledger, Bitcoin’s creator needed to find a way to keep people from trying to game the system and spend the same coins twice. Proof of work was a clever kludge—it wasn’t perfect, but it worked well enough. Ethereum’s mechanism has other drawbacks—it’s tediously slow, averaging 15 transactions per second. CryptoKitties, a game where players breed and trade cartoon cats, caused a transaction pileup on the network in 2017.

  • They are widely available on cryptocurrency exchanges, and many people still buy both for their perceived investment value rather than their current utility.
  • Bitcoin is absolutely hard money because its supply will never reach 21 million, making the cost of producing the 21 millionth bitcoin infinite.
  • There is currently no implemented hard cap on the total supply of Ether.
  • Blockchain technology is being used to create applications that go beyond just enabling a digital currency.
  • Crypto experts also say there is a risk that technical glitches could mar the Merge, and that scammers could take advantage of confusion to steal tokens.

Less coin issuance may help to raise the price of existing coins. Over time, as the wealth of this generation increases, their market share will inevitably increase. This will make the network dramatically more energy efficient than its current state. A 99.95% reduction in energy consumption may be the catalyst for regulation.

One of the primary goals of the Ethereum community is to make the platform more secure for investors and developers. In the past, we have seen several hacking incidents on different blockchains that resulted in people losing their money. Moving towards a PoS system, at least in theory, will minimize the risk of cyberattacks.

Ethereum also enables payments, using its internal ETH cryptocurrency, but its scope is much broader than Bitcoin by design. The performance of BTC and ETH often serves as a benchmark to gauge the overall health of the crypto market. Despite their dominance, these cryptos function very differently from one another.

Firstly, it greatly increases the resource costs of running a full node. The size of the Ethereum blockchain is larger and is growing faster than Bitcoin’s blockchain. This already makes running an Ethereum full node prohibitively difficult for the average user. While Ethereum and several forks of Bitcoin have attempted to scale the blockchain itself, Bitcoin is scaling off-chain by using layers such as the Lightning Network and the Liquid Network.

As we can see, the market is already beginning to tip in ether’s direction. When the Merge is complete, Ethereum is positioned Ethereum vs Bitcoin to be a deflationary asset. Aaron Samsonoff of InvestDEFY expects a 90 percent drop in new Ethereum token issuance post-merge.

The Byzantine Generals Problem describes the difficulty decentralized parties have in trustlessly establishing consensus. Bitcoin miners must submit Proof-of-Work in the form of a valid hash in order to have their block be considered valid. Ethereum’s failure to scale is a well-established fact within the developer community. This much was admitted by the Ethereum Foundation and Consensys, a company dedicated to building on Ethereum and funding its development.

However, the majority of Bitcoin users and developers wanted to keep Bitcoin safe, simple, and scalable. This switch will allow Ethereum to introduce sharding down the road . Sharding, according to, will dramatically reduce transaction fees while increasing transactions per second.

Every single Bitcoin user can independently and objectively verify the total supply of Bitcoin and the validity of each coin by typing a single line of code on their node. Ether’s monetary policy has been updated and revised several times over the course of its history. As of 2021, the policy is being altered once again by Ethereum Improvement Proposal 1559. These arbitrary changes make Ether’s monetary policy unsound, and undermines any possibility of Ether being absolutely scarce in the future.

In Bitcoin, every time a miner adds a block to the blockchain, he is rewarded with 6.25 bitcoins, a rate set in November 2021. In Etherium a miner, or validator, receives a value of 3 ether every time a block is added to the blockchain, and the reward will never be halved. Moreover, developers have been working on a layer-two scaling solution, referring to a solution that would build a transaction layer on top of the base blockchain called the Lightning Network.

Both Bitcoin and Ethereum are powered by their respective blockchains using proof of work consensus to validate transactions. Once 51% of the network’s nodes agree that a transaction is valid, it’s permanently uploaded to the blockchain. Ether and Bitcoin are the cryptocurrencies that enable these decentralized networks, and both of these assets have a limited supply.

Ethereum uses 113 terawatt-hours per year—as much power as the Netherlands, according to Digiconomist. A single Ethereum transaction can consume as much power as an average US household uses in more than a week. Energy consumption is much higher with proof of work than with proof of stake.

There Are Two Types Of Nodes

In fact, it’s four times larger than the third-largest cryptocurrency. Similar to Bitcoin, Ethereum has also seen a strong rise in its value, consistently remaining above the $2,000 mark since April 2021. Ether can also be used as a currency like Bitcoin, although the demand for the Ether token is not as substantial. There are no limits to how many tokens people can produce during its lifetime, however the blockchain has a cap of 18 million per year. The value of Ethereum would vary surrounding its operations and the demand for tokens on different dApps.

For this to be possible, the network needs to be designed so that it is impossible — or at least, highly unviable — for participants to double-spend units of cryptocurrency or to roll back prior transactions. Here are our picks for best Ethereum and cryptocurrency exchanges. Ethereum can support smart contracts, software programs that execute automatically when certain conditions are met. Bitcoin is primarily a store of value and medium of exchange; Ethereum is seen as a general purpose blockchain.

“Settlement using blockchain to Automate Foreign Exchange in a Regulated environment “. Ethereum was announced at the North American Bitcoin Conference in Miami, in January 2014. During the conference, Gavin Wood, Charles Hoskinson, and Anthony Di Iorio rented a house in Miami with Buterin at which they could develop a fuller sense of what Ethereum might become. Di Iorio invited friend Joseph Lubin, who invited reporter Morgen Peck, to bear witness.
