Vertcoin (VTC) was 51% attacked

Preamble

Vertcoin is a Bitcoin clone that aims to be ASIC-resistant by hard forking to new mining algorithms whenever ASICs are deployed on the network. Vertcoin was previously 51% attacked in Dec 2018 and has since changed its proof-of-work algorithm to Lyra2REv3. On Nov 30th 2019, a Vertcoin miner noticed a large upswing in hashrate rental prices for Lyra2REv3 on Nicehash. This was combined with workers connected to Nicehash's stratum server being sent work for unknown (non-public) Vertcoin blocks. I contacted Bittrex, Vertcoin's most prominent exchange, to recommend they disable the Vertcoin wallet on their platform once it became clear an attack was in progress, which they subsequently did.

The Attack

On Sunday, 1 December 2019 15:19:47 GMT 603 blocks were removed from the VTC main chain and replaced by 553 attacker blocks. We

CPU-minable coins

This file records the cpu-minable coins that I've experimented with. My goal is to keep a list of those that can be mined with a normal machine, like a home laptop, and are profitable. My definition of profitable is a coin that you can mine while using the machine for normal activities, like browsing the web, obtaining at least 1-2 coins per hour.

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
