Ethereum is a central building block of the economy developed around cryptocurrency. Launched in , Ethereum introduced functionality that Bitcoin does not offer.
While Ethereum, like Bitcoin, can be used for peer-to-peer payments, Ethereum also allows developers to write applications that interact directly with its code. It remains one of the most expensive cryptocurrencies to use, thanks to high transaction fees that pay for the computing power to run the network.
Transaction speeds also can be relatively slow. Several competing technologies, such as Cardano and Solana , have recently cropped up, promising to provide similar functionality more quickly or at a lower cost. Now, Ethereum has made a major shift in its underlying technology. The move pays the way for additional changes that could reduce the cost of using Ethereum, which has been a significant complaint among Ethereum users.
How much does Ethereum cost? Like most cryptocurrencies in recent months, Ethereum has fallen significantly off of all-time highs reached in This protocol ensures that the blockchain always accurately represents every transaction made. The nodes that actively participate in the consensus-building process are called miners or validators. Obviously, it can be a challenge for all the nodes to agree on everything, from the order in which the transactions should be processed to what the next block should look like.
In fact, maintaining the bitcoin blockchain for one year consumes as much energy as the entire country of Ireland uses in that same time period. Therefore, to help them cover their electricity costs, miners and validators are allowed to give themselves 12 bitcoins for every block they add. As you might imagine, the decentralized nature of blockchain makes the process a bit slow compared to conventional databases. Nonetheless, that means blockchains are a thousand times faster than transactions made on the stock market, which take around three days to finalize.
And compared to credit card payments, which take around four months, a blockchain transaction is about , times faster. Ethereum Key Idea 4: Thanks to their ability to perform automated functions, blockchains can also be applied to contracts. They can also be used to create a binding contract between two or more parties. In the world of contracts, any number of things can cause one or more of the parties to fail to fulfill their contractual obligations. And this can result in endless and exhausting periods of litigation.
Blockchains may obviate many contractual issues, however, since they can manage smart contracts. A smart contract not only stores the details of an agreement; it can execute the terms of the agreement as well. Smart contracts are essentially a legal text written as a computer program and inscribed into a blockchain.
And since blockchains never forget anything, a smart contract is certain to execute on time. So a blockchain smart contract can be used to trigger a payment at a certain time, whether the payment is made in cryptocurrency or with a traditional credit card.
Through the use of smart contracts, blockchains make it possible for decentralized autonomous organizations DAOs to operate. Bitcoin and Ethereum are just two examples of this kind of organization. A DAO is essentially a company built out of computer code and managed by blockchain.
It functions through a series of smart contracts that interact with each other in order to perform certain functions. You could think of a DAO as a car that not only drives itself but also regularly tunes itself up and takes care of itself. Some smart contracts function as the engine and keep it running, while others pay for gas or charge the battery.
And though the car represents its own organization, it could also be part of an Uber-like network. However, while things can run smoothly in a DAO, there can come a time when a problem arises and, with it, a question: Who should be held responsible?
Ethereum Key Idea 5: Blockchains have some problems that are still being resolved. One thing should be clear by now: blockchains are not a fad. But there are some issues that need to be worked out. One of the most important problems is that blockchains can lose data. This happens when two or more of the large groups in the computer network — the ones responsible for storing the information — are unable to agree on the correct state of the blockchain.
When this occurs, the network forks, or splits. So you could ask two nodes about your Bitcoin account, and if each node is on a different side of the split network, you could get two different account statements. Obviously, this would be a nightmare for every financial institution using the blockchain. A split can also occur if the connection between the nodes is cut.
This would cause the formation of isolated groups within the network. But such a split would be resolved as soon as the connection is reestablished. Unfortunately, this would mean that all transactions made on the smaller, rejected chain would be lost. Every transaction requires a sender address and a receiver address. This lack of confidentiality, especially as it pertains to extremely sensitive data such as medical information, might prevent blockchain becoming widely popular.
Ethereum Key Idea 6: Ethereum offers an alternative to the Bitcoin blockchain and currency. In addition to cryptocurrencies, Ethereum enables you to build such things as land-title registries and the kind of rating systems used on eBay and Amazon. Ethereum was invented in by Vitalik Buterin, who wanted to avoid the problem that highly specialized blockchains were experiencing when being employed for other uses.
Ethereum does come with its own digital currency — or its own bitcoin, so to speak — called ether. While Bitcoin may be the king of the cryptocurrency world today, ether, thanks to its more adaptable blockchain, could become the preferred digital-payment method of the future.
Ethereum Key Idea 7: Ethereum offers many possible applications, but there are still concerns. There are a number of ideas and potential applications of the Ethereum blockchain that make it quite exciting.

TURKISH DRONE TECHNOLOGY INVESTING
For PoW, the miner is the verifier, the miner is in the hands of the miner, and the miner can connect or disconnect at any time according to their wishes, that is, the hashrate is unknown and may change in a short period of time. So in order to get a safer sharding structure, PoW must be replaced by PoS. However, the energy consumption of Ethereum mining PoW is still more than Each transaction costs 84KWH kWh of electricity, which can supply a home for 2. Under PoS, maintaining the network system does not require the validator to repeatedly complete the hash calculation of the energy consumption, the energy consumption will be reduced by more than Only 35KWH of electricity is required per transaction, which is about the same energy consumption as watching a minute TV.
Changes after consolidation 3. Currently, the beacon chain only performs PoS operations on blank blocks, including the serial number of the slot, the parent block root, the status root, the proof, the deposit contract root, and the validator cut. The merged content is also called the execution payload information about execution , that is, the transfer of Ethereum provided by the execution layer formerly the PoW node and the interaction of smart contracts, and the execution layer and the consensus layer can be linked at the block level.
Since PoW is no longer used, PoW-related dynamic block strings, such as difficulty, mixHash, nonce, ommers, ommerHash, will be automatically modified to 0 or other constant values; The length of extraData will also be limited to 32 bytes. The consensus layer beacon node still validates all strings in the current beacon block, but the contents of the block are now validated by the execution layer the current POW. Ethereum employs the structure of a consensus layer and an execution layer execution engine to generate and synchronize blocks.
Previously, these two P2P networks were mutually exclusive. After merging, they must collaborate and coordinate while remaining independent. The transfer and invocation of the smart contract is packaged, broadcast, and executed by the execution engine formerly the ETH full node , and the tip of the GAS fee remains in the execution engine. The main goal of the execution layer is to establish communication with the execution engine, facilitate the generation or verification of the execution payload, and then create a complete beacon block based on the consensus of the beacon node.
The engine API acts as a bridge between the two networks. The consensus layer uses this premises to capture the content that requires consent from the execution engine and calls other execution engine nodes to verify the legitimacy of the transaction. Once consensus is reached, the latest network status is transmitted through the same channel to the execution engine, which synchronizes with that state from then on.
In other words, the consensus layer helped the previous PoW network reach consensus. As mentioned above, there will be a hierarchical relationship after the merge. The consensus layer is similar to the commander, while the executive layer is the soldier. This hierarchical relationship will reveal changes in consensus mechanisms and states.
The Ethereum beacon chain will employ PoS, which will be proposed by a committee of validators and voted on to reach a consensus on a block. After merging, the time units of a block will appear in the form of slots and epochs.
A slot is created every 12 seconds, and each Epoch pack consists of 32 slots. An epoch is a fixed time period in which inspectors will be reassigned at the end of this period. To become a validator and get voting rights, users must invest at least 32 ETH.
As of June 20, there are more than , validators. The system uses the stochastic algorithm RANDAO to assign 1 validator to each time slot, and at the same time randomly select a committee for this time slot. This validator is responsible for proposing blocks, while the committee is responsible for validating and voting on proposals. Once the vote is passed, a block is generated and the proposer is rewarded; Otherwise, not only will the reward not be obtained, but the deposit will also be forfeited.
The same applies to ordinary inspectors: if the rules are followed correctly, rewards are awarded, while saboteurs are punished. The random selection process of validators and commissions is hardly different from the chain of beacons before the merger. The only difference after the merger is that the merged consensus must include consensus on the implementation payload.
In the future, when there are more shards on Ethereum, i. First, Ethereum uses an account model, where each account consists of user status and contract status. State, in short, is the specific external display of the system at a specific time, including account balances, hashes of contract codes, or stored data. The full Ethereum status records all accounts and related account balances, as well as a history of all smart contracts deployed and executed in EVM.
After the nodes reach a consensus, a block on the main chain has only one state. In addition, the state of the system continues to change with the confirmation of new blocks. More specifically, the node that produces the chunk needs to access and check the current state of the system, record the new state after execution, and synchronize with other nodes in the network. Other customer nodes need to validate and execute transactions within the block to ensure that consensus is always present in the network.
As more new users enter and decentralized applications are deployed on Ethereum, more new data is generated, and the state data of the account grows indefinitely. For nodes, it is almost unrealistic to store all the state data in memory. If you are considering a hard drive, the speed at which the mechanical hard disk reads data may be too slow, which makes it difficult to synchronize the latest data with the node, while the SSD is not cost-effective. In the long run, the problem of state inflation will require nodes to have more storage space and stronger performance, which increases the threshold for node operation.
To solve the problem of state inflation, the community has proposed two possible solutions: state rent and stateless. The former imposes a continuous rent on contracts in a reserved state, otherwise availability would be terminated, but this is complicated in practice: on the one hand, the appropriate way of collecting rent cannot be determined; On the other hand, it is difficult to say who can be the legal recipient of the rent, so the exploration of the rent mechanism has stopped.
The latter proposes to make all transactions and states of the verification process without the actual storage of any state of the light client. The question boils down to one, why is statelessness so critical for PoS Ethereum? First of all, if you simply add eth1 execution and all state functions to all Beacon clients, then the threshold of hardware is too high for nodes.
Considering the increasing difficulty of full-node operation, the degree of centralization on Ethereum is exacerbated. Ethereum may have multiple shards in the future, each consisting of an account and the contract status deployed on it. Each shard randomly selects validators to form a committee; That is, if there is no stateless, the validator must have all the state data for all the shards, which can overwhelm the average validator, which can alleviate the poor performance of Ethereum, while stateless solidifies the highly decentralized Ethereum network.
Statelessness is crucial in laying the groundwork for future updates, and it is a major technological upgrade. Clients without an ETH1 execution engine 2. Client with ETH1 execution engine, stateless 3. The client with the full status of the ETH1 execution engine The first type of client is the lightest because it can only participate in consensus, but cannot validate transactions from the execution layer. It exists to oversee other types of nodes on the consensus layer. The third type of client is fully functional, with all the state, execution and consent, in other words, a complete node.
The number of third types of clients will be small, as the required investment could be huge amounts of data storage, hardware, and tokens for collateral. The second type of client has an advantage in terms of statelessness because it calls data from a stateful execution engine and uses its own execution power to verify the validity of transactions.
Because of the cost savings in state storage, the second type of client may be more common in the network. Features of the merger 4. In any case, each block can be generated after each time period, which takes 12 seconds. For on-chain transactions, the user must wait for the miner to pack. When the time it takes to produce a block is known, one can easily estimate which block may consist of transaction data at a certain time period, thus predicting the time it will take to complete the transaction.
That is, in the previous mode, even the time period for generating a block was about 14 seconds, and when the network faced congestion, the time required to generate a block became uncertain, which led to the instability of the token release of some DeFi protocols. Based on past experience, each upgrade was made at a certain height in the block.
For example, the Berlin upgrade occurred at a block height of 12,, However, specific plans have been delayed due to changes in the time it takes to produce new blocks, which has led to dissatisfaction with the development team in the community, but if the timing of the production block is determined, it may alleviate the situation. After the merger, Ethereum enables lightweight nodes that previously could not save the full state of the network to participate in the network and verify all transactions and proof of state.
In other words, the giant miner is no longer a must for the node, and the service-level equipment is enough to participate in the verification network. For end users and developers, the execution layer is where most of the interaction with Ethereum takes place, and most features such as EVM, state, and execution methods, etc. Possible effects No words are enough to accurately describe what the merge means for Ethereum.
This way, it automatically buys crypto when its prices dip, and sells when it peaks. Ethereum Trader App: Legit or a Scam?
