The key milestones for Ethereum is listed below. If you have any suggestions/additions, please contact us or drop a comment below.
January 2014 – Vitalik Buterin announces Ethereum Project at The North American Bitcoin Conference.
May 2015 – Ethereum launches Olympic testnet, a trial version before the official launch of Frontier.
July 2015 – Ethereum launches Frontier, a command-line version of the platform for developer testing.
August 2015 – Kraken becomes the first major digital currency exchange to list ether for sale.
January 2016 – Eleven major banks – Barclays, BMO Financial Group, Credit Suisse, COmmonwealth Bank of Australia, HSBC, Natixis, Royal Bank of Scotland, TD Bank, UBS, UniCredit and Wells Fargo, announce a trial of a permissioned version of the Ethereum platform.
March 2016 – Ethereum releases Homestead, the first “production-ready” version of the platform.
March 2016 – The total market value of all existing Ether tokens exceed US$1 Billion dollars.
May 2016 – The DAO becomes the largest decentralized autonomous organization, collecting more than $160 million worth of Ethers to be invested in other projects.
June 2016 – The DAO collapses after an unknown attacker exploit a flaw in the project’s code, that allows him/her to siphon Ether out from the DAO. Thankfully, a cooling down period was implemented in the DAO and the attacker are not able to withdraw the funds until some time later. This allows the Ethereum community to figure out the best way forward.
July 2016 – Ethereum undergo a protocol-level code change to undo the damage done by the attacker on the DAO. All customer funds are placed in a refund contract for withdrawal by affected customers.
August 2016 – A group of disillusioned people has maintained the abandoned Ethereum chain – now termed as Ethereum Classic. Citing the importance of immutability in blockchain technology, they rejected the existence of Ethereum and promoted Ethereum Classic as the “one true chain”.
September 2016 – An individual or group of people has conducted denial-of-service (DOS) attacks on Ethereum, starting just before Devcon 2 (a major Ethereum conference). Exploiting the fact that several operations are priced wrongly (a lot cheaper than what it should have been), the attacker(s) successfully caused a majority of the Ethereum clients to crash under massive load and the Ethereum network to slowdown. Clients developers partially mitigated the attacks by implementing improvements, e.g. better caching.
October 2016 – Ethereum successfully corrects the wrongly priced operations. However, it was discovered that there is still one last operation (EXP) that should be 3 to 8 times more expensive.
November 2016 (1) – Ethereum successfully implemented several improvements to harden against denial-of-service (DOS) attacks and added in some code to “sweep” away ~20 million “spam” accounts (that was created during the DOS attacks). JP Morgan released the source code for Quorum (a permissioned Ethereum fork) on GitHub.
November 2016 (2) – Due to errors in the implementation of EIP-160 within Geth and Parity clients, the Ethereum network underwent an unintentional fork (into two chains). The devs come to a consensus that the Ethereum chain supported by Parity clients will be the correct chain. An update was released by the Geth devs to fix the consensus issue within 8 hours.
