  2. Kovan Testnet proposal

    Happened on March 1st, 2017

    This proposal is to introduce a new testnet to provide a stable, secure testnet environment for Ethereum developers, due to the instability of the existing Ropsten testnet. On 24th Feb 2017, Ropsten was under a denial-of-service attack (“spam attack”). Average block propagation time has since slowed to a crawl as a large miner has decided to deploy several zero-value high-gas transactions to spam the test network continually. The attacker’s intentions are unknown, but the result is that Ethereum developers who rely on Ropsten no longer have a stable public testing environment to deploy and test their smart contract code prior to deploying to production on the mainnet chain.

  4. Plasma Cash Simple Spec Published

    Happened on March 14th, 2018

    A Plasma chain is a separate blockchain anchored to Ethereum Mainnet but executing transactions off-chain with its own mechanism for block validation. Plasma chains are sometimes referred to as "child" chains, essentially smaller copies of the Ethereum Mainnet. Plasma chains use fraud proofs (like optimistic rollups) to arbitrate disputes. Plasma Cash is a Plasma construction based around the use of unique identifiers for each token on the Plasma chain. Similar to cash in your pocket, tokens on the network are given unique serial numbers. https://karl.tech/plasma-cash-simple-spec/

The issue can be exploited to cause a denial-of-service condition, code execution has been deemed unlikely. This issue has been tested on OpenArena, but should be present in all 28 games using the idTech3 (ioquake3) engine.” OpenSea took down the auction and listing after it was posted.
