Ethereum’s 5th birthday – charting its journey so far
Ethereum Classic is an open source , blockchain -based distributed computing platform featuring smart contract scripting functionality. Ethereum Classic maintains the original, unaltered history of the Ethereum network. However, due to a hack of a third-party project, the Ethereum Foundation created a new version of the Ethereum mainnet on 20 July with an irregular state change implemented that erased The DAO theft from the Ethereum blockchain history.
Ethereum Classic's native Ether token is a cryptocurrency traded on digital currency exchanges under the currency code ETC. Implemented on 11 December , the current ETC monetary policy seeks the same goals as bitcoin of being mechanical, algorithmic, and capped.
ETC can be exchanged for network transaction fees or other assets, commodities, currencies, products, and services.
Ethereum Classic provides a decentralized Turing-complete virtual machine , the Ethereum Virtual Machine EVM , which can execute scripts using an international network of public nodes. The virtual machine's instruction set is Turing-complete in contrast to others like bitcoin script. Gas, an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network. Several codenamed prototypes of the Ethereum platform were developed by the Ethereum Foundation, as part of their proof-of-concept series, prior to the official launch of the Frontier network.
Ethereum classic followed this codebase after the DAO incident. On 28 May , a paper was released detailing security vulnerabilities with the DAO that could allow Ether to be stolen. On 12 June , Stephan Tual publicly claimed that the DAO funds were safe despite the newly-discovered critical security flaw.
On 15 July , a short notice on-chain vote was held on the DAO hard fork. Proponents of the fork were quick to market the vote as an effective consensus mechanism, pushing forward with the DAO fork four days later.
The first Ethereum Classic block that was not included in the forked Ethereum chain was block number 1,,, which was generated by Ethereum Classic miners on 20 July A mechanism called the "Difficulty Bomb" was designed to push the Ethereum chain from proof-of-work consensus mechanism to proof-of-stake in the future by exponentially increasing the difficulty of mining. This Difficulty Bomb was added to the network on block , in an upgrade named "Ice Age".
While Ethereum Classic participants debated the merits of the Difficulty Bomb, a network upgrade called "Die Hard" at block 3,, delayed the effects of the mechanism. Once the network participants came to consensus on the issue, Ethereum Classic upgraded its network on block 5,, to permanently defuse the Difficulty Bomb.
This abandoned a future with proof-of-stake and committed the network to the proof-of-work consensus mechanism. In an attempt to modernize the Ethereum Classic protocol, several protocol upgrades were scheduled to activate features that the Ethereum network already enabled over the past years. Atlantis, activated in September , enabled the outstanding Byzantium changes, Agharta, in January , brought Ethereum's Constantinople patches, and Phoenix finally achieved protocol parity between Ethereum Classic and Ethereum with the introduction of the Istanbul protocol upgrade.
Since the Phoenix protocol activated, applications are fully cross-compatible between the networks. After evaluating various options such as Monero's RandomX or the standardized SHA , it was eventually decided to double the Ethash epoch duration from 30, to 60, in order to reduce the DAG size and prevent Ethash miners to easily switch to Ethereum Classic.
This modified Ethash is also referred to as EtcHash or Thanos upgrade. As with other cryptocurrencies, the validity of each ether is provided by a blockchain , which is a continuously growing list of records , called "blocks", which are linked and secured using cryptography. It is an open, distributed ledger that records transactions between two parties efficiently and in a verifiable and permanent way. This does not rely upon unspent transaction outputs UTXOs.
The state denotes the current balances of all accounts and extra data. The state is not stored on the blockchain, it is stored in a separate Merkle Patricia tree. A cryptocurrency wallet stores the public and private "keys" or "addresses" which can be used to receive or spend Ether.
With the private key, it is possible to write in the blockchain, effectively making an ether transaction. To send Ether to an account, the Keccak hash of the public key of that account is needed. Ether accounts are pseudonymous in that they are not linked to individual persons, but rather to one or more specific addresses.
ETC is a fundamental token for operation of Ethereum Classic, which thereby provides a public distributed ledger for transactions. It is used to pay for Gas, a unit of computation used in transactions and other state transitions.
Within the context of Ethereum Classic it might be called ether, but it should not be confused with ETH, which is also called ether. It is also used to pay for transaction fees and computational services on the Ethereum Classic network. Ethereum Classic addresses are composed of the prefix "0x", a common identifier for hexadecimal , concatenated with the rightmost 20 bytes of the Keccak hash big endian of the ECDSA public key the curve used is the so-called secpk1 , the same as bitcoin.
In hexadecimal, two digits represent a byte, meaning addresses contain 40 hexadecimal digits. An example of an Ethereum Classic address is 0xbf5ea0bacefffba Contract addresses are in the same format, however, they are determined by sender and creation transaction nonce. Any valid Keccak hash put into the described format is valid, even if it does not correspond to an account with a private key or a contract.
This is unlike bitcoin, which uses base58check to ensure that addresses are properly typed. Socially, this block reward reduction event has taken the moniker of "the fifthening. The people who continued with Ethereum Classic advocate for blockchain immutability, and the concept that "code is law"  against the pro-fork side Ethereum which largely argued for extra-protocol intentionality, decentralized decision-making , and conflict resolution.
On 13 January , the Ethereum Classic network was updated to resolve transaction replay attacks. The networks are now officially operating separately. They set up a refund contract on the ETC network.
On 29 June , the Ethereum Classic Twitter account made a public statement indicating reason to believe that the website for Classic Ether Wallet had been compromised. The Ethereum Classic Twitter account confirmed the details released via Threatpost. The Ethereum Classic team worked with Cloudflare to place a warning on the compromised domain warning users of the phishing attack.
In January , Ethereum Classic was subject to double-spending attacks. From Wikipedia, the free encyclopedia. Open source blockchain computing platform. Main article: The DAO organization.

Ethereum Block Production Continues to Slide
The Ethereum network will soon conduct a planned Arrow glacier upgrade with the same purpose as the Muir glacier upgrade. Basically Arrow Glacier changes the delay parameters of the network difficulty bombs to June At the Ethereum block height of 13,,, the network will perform the Arrow Glacier upgrade to delay the difficulty bomb accordingly notification officially. The difficulty bomb is set to occur after 4,, blocks, or days after the Muir Glacier upgrade.
Ethereum’s Arrow Glacier Upgrade to Delay Ice Age’s ‘Difficulty Bomb’ Till Summer 2022
However, everything did not go as it was expected to. The Istanbul hard fork was aimed at reducing the gas cost of Ethereum network while also improving the privacy of the network. The fork was to increase interoperability with Zcash. The feature increases the difficulty every , blocks, which makes it impossible for miners to adapt to the difficulty level. This has resulted in a significantly slower block time and caused the network to slow down. If the issue persists, the network might start freezing all the time. Whenever the network undergoes a hard fork, the developers push back the Ice Age feature to make blocks fast.
The Coercion Of Ethereum's Difficulty Bomb
Ethereum is a cryptocurrency network that, like others, relies on a consensus mechanism that uses large amounts of energy and computational power. This encourages scalability and centralization of the technology into large mining farms created by people or businesses with significant assets. However, this centralization goes against the original tenets behind cryptocurrency. Ethereum's "difficulty bomb" refers to the intentional and sudden increase in mining difficulty that will occur when ETH 2.
What is the Ethereum Difficulty Bomb (Ice Age)?
In this article, we go through both of these Ethereum Network upgrades, along with the Ethereum Improvement Proposals EIPs that will be packaged with them. First of all, why do Ethereum network upgrades even matter? Although network upgrades like these are relatively technical, they can still be important for Ethereum fundamentals. So, what do the upcoming two Ethereum hard forks entail? It has perhaps never been more important to keep an eye on the upcoming Ethereum network updates, with Ethereum recently reaching new all-time highs. Granted, Ethereum has not been the sole focus of the cryptocurrency sector in
Delaying the Inevitable: Muir Glacier
This will give the Ethereum network another six months until it leads to the participation test PoS transition of the network. At the height of the Ethereum block 13,,, the network will implement the Arrow Glacier update which aims to postpone the Ethereum difficulty pump. The mechanism of the pump has existed since and makes the mining difficulty of the network increase over time. The difficulty bomb was to pass 4,, blocks or days after the Muir Glacier network upgrade. However, Arrow Glacier will roll back the bomb until June This will give the Ethereum PoW miners six more months to continue operating the Ethereum blockchain until the change of June Once the difficulty bomb passes , the difficulty of mining will cause PoW miners to be phased out because it will be too difficult. Arrow Glacier is expected to take place from now until Wednesday, December 8,

Delay the Ice Age – Ethereum Network Participants Prepare for Arrow Glacier’s Next Upgrade
This hard fork addresses the impending Ice Age on Ethereum Mainnet and includes a commitment to solving the problems with the ice age more permanently. Ethereum achieves a consistent block time due to its' difficulty retargeting algorithm. If a block-time is higher than 20 seconds, it reduces the difficulty, and if a block time is lower than 10 seconds, it increases the difficulty. This mechanism reaches typically an equilibrium of around seconds. Included within this mechanism is something we refer to as the Difficulty Bomb or the Ice Age.
Ethereum mining cliffs rose from summer 2022 to December 2021
Block time defines the time it takes to mine a block. Both in bitcoin blockchain and ethereum blockchain, there is an expected block time, and an average block time. In bitcoin, the expected block time is 10 minutes, while in ethereum it is between 10 to 19 seconds. Both bitcoin and ethereum, at the time of this writing use a proof of work based distributed consensus algorithm ethereum is planned to move to a proof of stake based algorithm with its serenity release. The expected block time is set at a constant value to make sure, miners cannot impact the security of the network by adding more computational power. The average block time of the network is evaluated after n number of blocks, and if it is greater than the expected block time, then the difficulty level of the proof of work algorithm will be reduced, and if it is less than the expected block time then the difficulty level will be increased. The level of difficulty varies with the time, as per the following formula.
Ethereum Devs Decide to Increase Inflation, Delay Difficulty Bomb
Two weeks ago, we wrote this Medium post in which we describe the slowdown in per-week block production due to the Ice Age or Ethereum Difficulty Bomb. We thought it would be interesting to continue to watch the process as it unfolds. The following chart is the one we presented two weeks ago.
