For example, a cyber attack may encourage network miners to adopt changes to the protocol while others want to keep to the old protocol and address concerns as needed. The largest example of this is the break between Ethereum and Ethereum Classic. Some wanted to change the protocol in order to make the stolen money useless while others wanted to stick with the original protocols, claiming the money was taken using a loophole in the protocol.
Second, it introduced new codes in Solidity, the programming language used on Ethereum. The Homestead upgrade was one of the earliest implementations of Ethereum Improvement Proposals. EIPs are recommendations made to the community that then, if approved, are included in network upgrades. The Homestead upgrade included three EIPs:. EIP 2. The cost to create a contract via another contract — the preferred method — had cost more than creating it via a transaction. By increasing the gas cost to create contracts via transactions, EIP 2.
The ECDSA recover precompiled contract remained unchanged and kept accepting high s-values; this is useful e. This changed the possible outputs of a transaction from [success] [fail] or [empty] to just [success] or [fail]. EIP-8 was an Improvement Proposal with an eye towards future, planned network upgrades. The improvement ensured all client software on Ethereum could accommodate future network protocol updates.
In the history of planned Ethereum upgrades and hard forks, the unplanned DAO incident deserves inclusion. The Ethereum community at large decided to hard fork the chain in order to restore the funds to their original wallets and patch the vulnerability. The hard fork, however, was contentious, and some in the Ethereum community continued to mine and transact on the original chain.
The original chain — with the stolen ether not returned — became Ethereum Classic, which has become weaker and subject to exploitation over time. The majority of the community and the core developers continued working off the forked chain — with the stolen ETH returned to their original owners — which is what we now know as the Ethereum blockchain. Byzantium went live in at block 4,, and included nine EIPs, including:. Adjusted the formula to assess the difficulty of a block to take into account uncle blocks.
The new formula provided stability to the issuance rate, ensuring it could not be forced upward by manipulating uncle blocks. For blocks following the Byzantium upgrade, transaction receipts included a status field to indicate success represented by 1 or failure represented by 0.
The Difficulty Bomb is a mechanism that, if activated, would increase the energy required i. Its purpose is to support the eventual transition away from Proof of Work towards Proof of Stake. When PoS is implemented, miners could theoretically choose to support the old PoW chain, thus causing a split in the community and the creation of two separate chains — one maintained by stakers and one maintained by miners.
The solution for this not to happen is to implement the Difficulty Bomb, which would eventually phase out the efficacy of mining and allow for the complete transition of the network over to PoS without the threat of a contentious hard fork. An overview of the remaining Byzantium EIPs , , , , , found here. The second part of the Metropolis upgrade, named Constantinople , was scheduled to go live at block 7,, — estimated in mid-January On January 15th, an independent security auditing firm named ChainSecurity published a report that indicated one of the five main system upgrades could provide attackers with the opportunity to steal funds.
In response to the report, core Ethereum developers and the extended community voted to delay the upgrade until the security loophole could be resolved. Later that month, the core developers announced the upgrade would take place at block 7,, Block 7,, arrived on February 28th and the Constantinople hard fork upgrade went live.
The instructions allow for bits of binary information to move to the left and to the right. This improvement means the execution of shifts in smart contracts will be 10x cheaper. Allowed for smart contracts to verify one another by pulling just the hash of the other smart contract.
Before Constantinople, smart contracts would have to pull the entire code of another in order to verify, which took time and energy to perform. Improved the enablement of state channels , an Ethereum scaling solution based on off-chain transactions.
The same month, CryptoKitties reached , registered users. How could Ethereum become the world computer when one viral dapp was enough to overwhelm it? If the developers wanted to be serious about onboarding not thousands but millions of dapp users, they would need to come up with a concrete plan to increase throughput.
The need for Ethereum 2. The popularity of initial coin offerings ICOs — a way to crowdfund early stages of a cryptocurrency project — by dollar amount raised reached its peak in Trends like the ICO boom of are indicative of the ways blockchain technology can be leveraged in more ways than simply peer-to-peer electronic cash.
As a result, despite the technical limitations of the platform, dapp developer activity on Ethereum continues to thrive. The latest trend dominating user traffic and transaction volume on Ethereum is decentralized finance DeFi. The DeFi movement currently sweeping Ethereum is made up of dapps modeled after traditional financial players such as lending services, exchanges and derivatives markets.
In order to ensure interoperability between different dapps on the network, common frameworks were developed — like the ERC and ERC token standards. EOS, Stellar, Tezos and Tron are four cryptocurrencies in the top 15 by market share that also feature dapp creation and deployment.
Despite the growth in the number of alternative dapp platforms, Ethereum remains the most popular general-purpose blockchain both in terms of number of users and dapps, as shown in the chart above. Developers are convinced that the current blockchain infrastructure is wholly inadequate to handle an influx of millions, if not billions of users around the world. This was always the suspicion of the early founders of Ethereum, including Vitalik Buterin. Eth 2. Developers are convinced that the current blockchain infrastructure is wholly inadequate to handle an influx of millions, if not, billions of users around the world.
This was always the suspicion of the early founders of Ethereum such as Vitalik Buterin. The Ethereum 2. Originally, Ethereum 2. The bomb, which was activated on March 14, , increases the difficulty levels for miners to find an Ethereum block over time.
This schedule at which this bomb slows block production has been delayed three times over the course of the last five years as developers re-worked plans for launching Ethereum 2. The most recent delay to the difficulty bomb occurred on Jan.
This may be the last time the difficulty bomb is pushed back as tentative estimations by some developers suggest the transition to Ethereum 2. While there is no telling what new technologies and standards of blockchain practice will be innovated as a result of Ethereum 2. In that time, Ethereum has undergone network-splitting upgrades, faced crippling technology bottlenecks, advanced new forms of fundraising for crypto projects and formalized a launch plan for migrating to Ethereum 2.
