All 64 sharded chains are connected to one blockchain, which controls all of them and enables transactions throughout the network. This central component is the brain of the entire ecosystem and is named Beacon Chain. However, the older Ethereum blockchain could handle only 15 transactions per second. It caused the users to pay high transaction fees and deal with delayed transfers. 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.
While 51% attacks in Proof of Work systems can be damaging, they only really directly affect those who are exposed to double spends; mostly exchanges, and not long term holders who do not transact frequently. In contrast, 33% attacks can halt the chain in perpetuity on PoS networks. This same user DOGE is locked out of Proof of Stake blockchains, making those networks less accessible, less useful, and less valuable.
Nakamoto Consensus is the most secure consensus mechanism
„If Classic achieves the position as the dominant application of the hash power, its risk exposures would drop to a minimum,“ it adds. The previous high was 28.32 terahashes last May, coinciding with ETC’s all-time-high price of $118. The hash rate of ETC hits an all-time high, which reduces the risks of a „51% attack.“
Proof of Work and Proof of Stake are common consensus mechanisms used for processing transactions and creating new blocks on a blockchain. These two types of consensus mechanisms incentivise good behaviour and make it difficult and expensive to act maliciously. When functioning as intended, this prevents fraud like double-spending, the act of making payments twice with the same currency in order to deceive the recipient of those funds. On blockchain networks like Ethereum, there has to be a way to validate transactions in a decentralized manner, without a centralized authority, such as a bank. Currently, Ethereum, along with other popular cryptocurrencies like Bitcoin, use what’s known as Proof of Work .

- The hash rate of the Ethereum Classic network—a measure of the computational power per second used when mining a cryptocurrency—hit an all time high on Thursday.
- Both Ethereum and Ethereum Classic are founded on the same whitepaper proposed by Vitalik Buterin in 2014 and are powered by similar computer code through smart contracts.
- Identified by its ticker symbol, ETC, Ethereum Classicoperates under smart contracts and produces Ether under the ETC token name.
- Most importantly, Ethereum Classic is incompatible with updates to the Ethereum blockchain.
Block building will likely have a more profound impact than many expect; for example, new dynamics created by block building may actually lead to your web3 wallet or dapp paying you to use it. In addition to proposing blocks and submitting attestations, validators can also monitor each other for malicious behavior and “slash” other validators for failing to uphold the security of the network. Slashable offenses are acts that are provably against the Ethereum network including double voting (e.g. proposing two blocks in the same slot) or submitting contradictory attestations (e.g. signing two different attestations in one epoch). A newer sharding design, called Danksharding, is gaining traction in the Ethereum community.
Briefly, the PoS consensus replaces the process of mining new blocks, which is used in the PoW, with the mechanism of validation. There the rights to adding new blocks are distributed between the participants according to their stake in the blockchain. „Ethereum plans to move to Proof of Stake in the near future, which will forcibly eject its mining interests,“ the report notes.
Since Ethereum Classic’s entire identity is based on preserving MATIC the original Ethereum platform as it was created, there are no plans to move to a Proof of Stake validation system. The platform calls this their pursuit of “decentralisation maximalism.” Ethereum Classic believes that PoS comes with too many compromises. When it comes to PoW, Ethereum Classic holds a certain “if it isn’t broken, don’t fix it” mentality, even though PoW is incredibly energy intensive and produces electronic waste that is detrimental to the environment. In fact, on their website, Ethereum Classic even suggests that Ethereum and other cryptos only use PoS because they are financially motivated, not because they have any regard for the environment. A lot will depend on how the market responds to The Merge, and whether ETC can end up attracting former ether miners.
The primary justification for PoS is environmentalism; it was hoped that PoS would be able to provide the same or better security guarantees than PoW without consuming large amounts of energy. The timeless wisdom of if it ain’t broke, don’t fix it comes to mind, and there must be a seriously important reason to change this state of affairs. A few differences between Ethereum and Ethereum Classic include the latter’s dedication to Proof of Work, its decision to implement a capped supply with a fixed emissions curve, and its smaller community. Overall, proof-of-stake, as it is implemented on Ethereum, has been demonstrated to be more economically secure than proof-of-work.
- The most recent of these tests, which took place on the Goerli testnet, successfully merged earlier this month.
- The transaction can be considered „finalized“, i.e., that it can not be reverted, if it has become part of a chain with a „supermajority link“ between two checkpoints.
- Unlike Bitcoin, Ethereum Classic operates using accounts and balances in a manner called state transitions.

Due to the confusion, a good rule of thumb is to be wary of anyone telling you that you’ve got unspent ETH or other assets just sitting on the other chain and offering to liquidate it for you. Ethereum Founder Vitalik Buterin has indicated that he would support measures to burn the stake of any validators that censor Ethereum’s protocol at the behest of regulatory bodies, but the concern remains. Requiring resource-heavy computing processes to try to mess around with the ledger disincentivizes people from doing so. Ethereum can be produced with as many tokens as necessary, although there’s a limit of 4.5 percent of growth each year. Bitcoin and Ethereum Classic vs Gold in the next ten years.The projected values for BTC and ETC are on a fully diluted basis, meaning BTC is calculated with a 21 million supply and ETC with a 210 million supply. With the spurious money printing in the present and in recent years by central banks in North America, Europe, and elsewhere, which is likely to continue in the foreseeable future, it is likely this projection will prove conservative .
Optimism price prediction: What is optimism (OP)?
As with automobile engines, different types of consensus mechanisms are available to blockchain architects when designing a protocol. The choice of which to use reveals much about which attributes in the Blockchain Trilemma trade-off are considered a priority. As a chain’s consensus mechanism is so important, for Sovereign Grade systems, it is the very last thing that should be on the chopping block when it comes to design constraints and security trade-offs. It is the most critical piece of technological infrastructure, from which all security, value and utility depends on. Like an engine, if it stops working correctly, all other systems that rely on it functioning become useless, or worse, a danger to its users.
etc proof of stake had to use highly-complicated computing devices, which consumed massive amounts of electricity. The newer PoS model, in sharp contrast, puts an end to the entire mining network, making Ethereum more sustainable and eco-friendly. So as an investor, you don’t need to worry about the ETH tokens stored in your wallet. Proof of Stake makes participating in the network more attainable for many more users and not just large miners.
Like Ethereum, Ethereum Classic can also be used to develop decentralized applications that can use native ERC-20 tokens. Those who were for the fork moved over to the main version of Ethereum most people know and use, with those who were against it remaining on the original chain, which was renamed Ethereum Classic. A group of miners decided they would be responsible for taking Ethereum Classic in a different direction to Ethereum while preserving the original code. As a result, Ethereum Classic doesn’t follow updates on the Ethereum blockchain, such as the Ethereum 2.0 Merge. Proof of work is the process of validating transactions on a blockchain to confirm transactions, close a block, and open a new one.
I’m not sure how that works. How is it related to proof-of-work or proof-of-stake, etc. ?

https://www.beaxy.com/ Classic became particularly popular throughout Summer 2022 due to the Ethereum proof of stake blockchain merge. Because the Ethereum blockchain has switched from proof of work to proof of stake, miners are no longer required to verify transactions. Under Ethereum’s PoS, if a 51% attack occurred, the honest validators in the network could vote to disregard the altered blockchain and burn the offender staked ETH. This incentivizes validators to act in good faith to benefit the cryptocurrency and the network. The PoS mechanism seeks to solve these problems by effectively substituting staking for computational power, whereby an individual’s mining ability is randomized by the network.
Does etc follow ETH?
Ethereum Classic (ETC) does not follow the same price trajectory as Ethereum (ETH). Currently, ETC is trading at $26, and ETH is trading at $2,800. One of the main reasons for the price difference is that ETC has a fixed supply, and ETH does not.
If a new project needs to make its presence felt in the world of blockchain, becoming eco-friendly is the most important thing it has to do. The older PoW consensus model required Ethereum’s blockchain to depend on mining. As mentioned earlier, Ethereum hosts a massive number of DApps and DeFi services.
Please note that an investment in crypto assets carries risks in addition to the opportunities described above. This article does not constitute investment advice, nor is it an offer or invitation to purchase any crypto assets. CFDs attract overnight costs to hold the trades (unless you use 1-1 leverage), which makes them more suited to short-term trading opportunities. You might also pay a broker commission or fees when buying and selling assets direct and you’d need somewhere to store them safely. CFDs are leveraged products, which means that you only need to deposit a percentage of the full value of the CFD trade in order to open a position. In the UK, there is no stamp duty on CFD trading, but there is when you buy stocks, for example.
Will Ethereum Classic remain proof-of-work?
Ethereum Classic remained a proof-of-work system. In the eyes of the Ethereum Classic community, the blockchain and code will always be immutable. It preserves the pre-merge, proof-of-work system. And that means miners are still required to validate ETC transactions.
Staking intrinsically provides an incentive for users to hold and not to sell. If you’re staking, you’re putting a portion of your portfolio towards the network’s consensus algorithm. In Proof-of-Work, on the other hand, miners have a greater incentive to instantly cash in and sell their block rewards.
