Digix Core Dev Weekly Update — Mar 1st 2017

Ropsten Hiccup
On 24th Feb 2017, Ropsten, Ethereum’s public test net, was under a denial a service attack (“spam attack”). Average block propagation time 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 to test their contracts no longer have a stable public testing environment to deploy and test their smart contract code prior to deploying to production.
The use of Proof-of-Work (PoW) for testnets presents a fundamental game theoretical problem: the only significant economic incentive to mine on testnets using dedicated GPU resources is to launch an attack and reduce stability and the viability of the testnet (and thus hamper development for the mainnet chain).
This means that testing on Ropsten may no longer be viable as these attacks will come continually / sporadically. We are working out alternatives as we speak, and will make a separate announcement soon.
Chris will be giving a presentation tomorrow at SG Innovate, together with Attores and Otonomos. Please tune into our channel for more information.
Chris Hitchcott (Digix Core Dev)
This week I’ve been working on Spectrum. I completed the web3-redux refactor, and have implemented `redux-orm` as the main datastore for the core project. This gives us the ability to have dynamic keystore ‘plugins’ with custom creation, editing and signing components. In simple terms, this means that adding new signing types (like uPort or 2FA) can be done in a decoupled way, and the ‘dapplet store’ can not only list dapplets, but also custom keystore providers.
