A quick note about an attack on Bitcoin that’s been observed in the wild recently. Block withholding attacks have been discussed for a long time—the term refers to two different things, confusingly, but what we’re discussing here is when someone (often from a competing pool) joins a mining pool that pays out based on the average hashrate of the pool but withholds valid blocks, so the pool misses out on earnings and potentially becomes unprofitable.

<p class="canvas-atom canvas-text Mb(1.0em) Mb(0)–sm Mt(0.8em)–sm" type="text" content="Recently,&nbsp;F2pool&nbsp;mentioned on wechat that it was observable from hashrate distribution that this was actually happening a lot. Interestingly, there’s been a proposed fix for this from&nbsp;Luke Dashjr&nbsp;for a&nbsp;long&nbsp;time, but it would require a hard fork so it hasn’t been implemented yet. While it might not be a massively urgent problem, I would love to see increasing adoption of things at the pool level which make Bitcoin more decentralized (like Matt Corrallos&nbsp;BetterHash) and I plan to write a bit more about that in the next issue.” data-reactid=”24″>Recently, F2pool mentioned on wechat that it was observable from hashrate distribution that this was actually happening a lot.

At the hackathon, he additionally built a visualizer for JavaScript package dependencies that colors each module node based on the level of security exposure.

    • We demoed our integration with Cosmos, running “Swingset” on a cosmos chain. In order to show our full stack, we built a simple pixel marketplace (think Million Dollar Homepage or Reddit’s /r/Place) that uses our Electronic Rights Protocol and provides the ability to color, buy, and sell pixels as well as create further abstractions.
