Although there are some solutions for handling cross-blockchain integration, the overall complexity of integrating smaller chains and altcoins will increase drastically. On-chain solutions On-chain solutions, sometimes also called layer 1 solutions, are to look for solutions to address scalability and performance issues at the base layer of the Ethereum blockchain network.
One such solution is sharding. Sharding is not a new concept as traditional RDBMS and new big data platforms have been using sharding as a way to improve scalability and performance for many years. With the Ethereum network, the purpose of sharding is to group the network nodes, the blockchain, and global states into different shards, and each shard will reach a consensus on the shard-wide transaction state among those nodes within the group.
At the conceptual level, this may not be much different from Plasma, the layer 2 side-chain approach, but the technical difficulty, implications, and network efforts are quite different. Another layer 1 or on-chain solution is the shift to a Proof of Stake PoS consensus mechanism, which is one of the most active research areas addressing scalability and performance issues in Ethereum.
There are many debates in terms of the advantages and disadvantages of a PoW-based consensus mechanism. It is quite effective in securing the blockchain in the decentralized network, but it is also a major bottleneck in the blockchain performance. To put it simply, Proof of Stake is one of the most popular consensus algorithms on blockchain networks. As opposed to PoW consensus, where miners are rewarded for solving cryptographic puzzles, in the PoS consensus algorithm, a pool of selected validators take turns proposing new blocks.
The validator is chosen in a deterministic way, depending on its wealth, also defined as a stake. Anyone who deposits their coins as a stake can become a validator. The chance to participate may be proportional to the stakes they put in. The following is how it works in the PoS consensus mechanism. As shown in the following diagram, the blockchain keeps track of a set of validators, sometimes also called block creators or forgers.
At any time, whenever new blocks need to be created, the blockchain randomly selects a validator. The selected validator verifies the transactions and proposes new blocks for all validators to agree on. New blocks are then voted on by all current validators. Voting power is based on the stake the validator puts in.
Whoever proposes invalid transactions or blocks or votes maliciously, which means they intentionally compromise the integrity of the chain, may lose their stakes. For the creation of the block itself, the node does not receive a reward. Remuneration is paid for the transaction. Upon the new blocks being accepted, the block creator can collect the transaction fee as the reward for the work of creating new blocks.
PoS is considered more energy-efficient and environment-friendly compared with the PoW mechanism. It is also perceived as more secure too. Similar to PoW, total decentralization may not be fully possible in the PoS-based public blockchain. This is because a few wealthy nodes can monopolize the stakes in the network. Those who put in more stakes can effectively control most of the voting and has more chances to generate a new block.
Both algorithms are subject to the social and economic issue that it makes the rich richer. Off-chain solutions Similar to the rationales for an on-chain solution, the Ethereum community is also actively looking for off-chain solutions, sometimes called layer 2 solutions. One is a side-chain solution with Plasma.
Instead of putting all transactions in the main chain, Plasma allows anyone to create side chains and bond side chains into the global blockchain. This is similar to the lighting network solution in Bitcoin. Another one is a state channel solution with Raiden, similar to payment channels in Bitcoin. The hypothesis behind this approach is that many interparty transactions only need to be validated by the parties involved, and there is no need to have all transactions to be validated by the entire network.
One intuitive solution to improve scalability and throughput is to create many small chains. This may sound like a plausible solution, since it may suit business and social needs. Take ourselves for example, as customers or citizens, we buy fruit and vegetables from our local grocery, which might leverage one blockchain to ensure traceability and food safety through the entire supply chain of fresh produce.
At the end of your shopping, you may pay the grocery directly through a P2P payment blockchain. When you apply your mortgage or business loan, you might be able to get your mortgage and loan approved through the mortgage blockchain, and so on. We are more likely to meet all these vertical chains or private chains before we see a gigantic global chain.
However, it creates cross-chain integration and security enforcement issues. This is what Plasma tries to address. The design idea is to offload transactions to many faster and less crowded side chains, also called Plasma chains. Similar to the state channel approach, a Plasma chain will periodically commit its transactions to the Ethereum root chain.
Security and integrity will be enforced through the root chain. If any suspicion of fraud is detected in the plasma chains, the transactions will be rolled back and Plasma users can exit the plasma chain and move out to the root chain. The following diagram shows what a Plasma network may look like: Each plasma chain is a blockchain on its own. They are bonded with an Ethereum root chain through a smart contract. The smart contract essentially connects an entire child chain to the root chain, acting as a bridge.
Anyone can create a plasma chain, and write a smart contract binding the plasma chain to the root chain. As the following diagram shows, at each period, the block headers of each block of the plasma chains are submitted to the root chain and recorded in the blocks of the root chain. Transactions in the plasma chains will stay at each plasma chain. The Merkle proof in the block headers will then be used to verify data on the child chain.
This allows for tens and thousands of transactions to be processed in many plasma chains in parallel, and also leaves minimal and enough Merkle header information on the root chain to enforce security: The root chain will play an arbitrator role, somewhat similar to the federal court system in the United States, where the root chain is the supreme court and the plasma chains are the circuit courts, or the district courts.
In the federal court system, once the federal district court has decided a case, the case can be appealed to the circuit court or supreme court for an arbitration. During this historic upgrade to the second-largest cryptocurrency by market cap, upon which well over half of all decentralized finance activity is built, could your funds and NFTs go missing, or your favorite apps stop working?
But confusion surrounding the event could spike instances of scammers manipulating uninformed users, and, looking to the months and years to come, the implications of the merge could well have long-term political and even legal ramifications. Because a campaign has emerged to fork, or split, Ethereum and preserve an alternative, proof-of-work version of the network, there exists a likelihood that all digital assets currently built on Ethereum will be duplicated come the merge.
Those copies will likely be worth far less than their legitimate counterparts on the Ethereum network, but the owners of these assets could still be tempted to sell these surplus tokens for some meager payday. A replay attack, however, could see bad actors duplicate these transactions in a manner that would allow them to steal the real, much more valuable version of the asset on the real Ethereum blockchain.
Chandler Guo, the founder of ETHPoW—by far the most prominent campaign to fork Ethereum during the merge —confirmed to Decrypt that his proposed network would change all chain IDs on its blockchain to prevent such attacks. The merge will take about 12 minutes to complete, and during that time numerous major crypto exchanges have announced that they plan to pause deposits and withdrawals for Ethereum and Ethereum-based tokens. But 12 minutes after, the chain finalizes.
Then everything should be fine.

Dagger involves the generation of a Directed Acyclic Graph , random slices of which get hashed together. The core principle is that each nonce only requires a small portion of a large total data tree. Dagger was designed to be an alternative to existing algorithms like Scrypt, which are memory-hard but difficult to verify when their memory-hardness increases to genuinely secure levels.
However, Dagger was vulnerable to shared memory hardware acceleration and dropped in favor of other avenues of research. As a result, existing RAM is likely to be moderately close to optimal for evaluating the algorithm. Hashimoto uses the blockchain as a source of data, simultaneously satisfying 1 and 3 above. Dagger-Hashimoto used amended versions of the Dagger and Hashimoto algorithms.
The difference between Dagger Hashimoto and Hashimoto is that, instead of using the blockchain as a data source, Dagger Hashimoto uses a custom-generated data set, which updates based on block data every N blocks. The data set is generated using the Dagger algorithm, allowing for efficiently calculating a subset specific to every nonce for the light client verification algorithm. The difference between Dagger Hashimoto and Dagger is that, unlike in the original Dagger, the dataset used to query the block is semi-permanent, only being updated at occasional intervals e.
More on Dagger-Hashimoto. Ethash Ethash was the mining algorithm that was actually used on the real Ethereum Mainnet under the now deprecated proof-of-work architecture. Every block mined rewards users a certain amount of cryptocurrency—thousands of dollars per block plus transaction fees. To make mining easier, some miners organized in "pools" where they would pool computing power and split the reward of each block, with rewards paid out depending on how much computing power each miner contributed.
Bitcoin was initially mineable with consumer hardware CPUs , but down the road, the mining difficulty increased to the point where purpose-built mining hardware like ASICs are needed to have a remotely acceptable profit. The difficulty of Ethereum, however, didn't increase that much. With a high-end RTX , you could easily make over twice that amount. Once you've recovered the money you invested, it was basically a completely effortless, stable income.
The Ethereum mining rush was partly to blame for the fact that the RTX series GPUs were non-existent on store shelves when released in , with crypto miners immediately snagging the few GPUs that did make it to retail. Of course, all good? As profitable as Ethereum mining was, the power consumption generated by that practice was enormous, ultimately damaging the environment. And the network itself was volatile, to the point where gas prices could spike and make transactions absurdly expensive. The Ethereum 2.
But in the process, it's leaving miners behind without their main source of income. Ethereum Mining Alternatives Common logic would dictate that if Ethereum mining is gone, people can go and mine something else. And while they can Ethereum 1. Let's look at some alternatives miners are considering. There are plenty of cryptocurrencies out there, like Ravencoin, ZCoin, and others. Bitcoin mining is out of the question, as it's so difficult to mine that trying to do so with a regular GPU-based rig is pointless, especially if you're a small-scale miner.
If you want to see an acceptable profit, you'll need an ASIC-based rig , which can be costly. With the price of Bitcoin fluctuating heavily, even if it's profitable at a certain point, a sharp drop can turn the scene around completely.
As for other cryptocurrencies, the difficulty might not be high, but most of them lack a tangible community, and as a result, they're not that valuable. When you mine something, you do it to get a reward out of it, and if that reward is worth basically nothing, there's no point in doing so.
Are you actually making money or just damaging your hardware and wasting resources to get a few extra dollars in exchange? Ethereum Forks Of course, we also have Ethereum forks.
