A Dead Man’s Switch

A key role in understanding what the Archaeologist does in Sarcophagus is to understand what a Dead Man’s Switch (DMS) is.


In this update, we had a chance to talk to the developers of Sarcophagus and got an in-depth look at what has been worked on recently, as well as upcoming plans on the roadmap. As was mentioned in last month's Sarcophagus Community Update, there are a lot of things brewing in the background with lots of moves coming up to help make the UX of the dApp much more streamlined, as well as looking forward to the next iteration of Sarcophagus.

The story of Bitcoin is a bit of magic, mystery, and intrigue all thrown together and encompassed in the white paper written by Satoshi Nakamoto and released on Oct 31, 2008. Part of the magic and mystery surrounds the pseudonymous author of the whitepaper, Satoshi Nakamoto, as the true identity of Satoshi is not really known. Satoshi may be a man, woman, or a group together working on the inner workings of what is now known as Bitcoin and the whitepaper was truly the genesis of what is now known as Bitcoin and cryptocurrency. In all honesty, anyone with any…


Still crushing blocks!

I haven’t had much time lately to write another recap but wanted to share a lot of the things I have learned since my last writeup. My previous post was written just after the crypto markets tanked in mid-May and have since recovered in the recent weeks. With this, so has the margins from mining become a little bigger, giving some breathing room.

What’s New


This month has been a pretty busy and fruitful month for the Sarcophagus community. There have been lots of enabling decisions and votes that have been made to help grow the community, user base and raise awareness of the project. In addition, there are plenty of opportunities to get involved in the $SARCO community; from social media forums/chats, contests & bounties as well as running nodes. This month is the start of helping to grow $SARCO further.

Key Points:


Since the dawn of time, people have worked to amass value and worth to help build generational wealth, make the best life for themselves, or even help serve a larger philanthropic purpose. The one thing that mankind can’t do is know when the unforeseen may happen: death, abduction, political uncertainty… In these cases, what happens to the belongings of those poor unfortunate souls? They become lost, tied up in some legal battle, or worse confiscated. Sarcophagus is a blockchain-based solution to help solve this problem. By implementing a decentralized dead man’s switch, the digital assets of an individual can be…

Latest and Greatest Update to the Mining Rig

Brief Recap

In a couple of previous articles, I wrote about how to go about getting started with building a crypto mining rig as well as the first iteration and part list and costs of my initial build. You can find that information in the article below.

As you probably can see in the thumbnail picture of the article above, A LOT has changed since my last article. Some changes better, while some worse (which I’ll mention and describe in detail). Overall, since starting this “hobby” of crypto mining I have thoroughly enjoyed some of the challenges that come along with acquiring…

In Python or any other programming language when trying to solve problems and/or manipulate a dataset, counting the number of elements with a given property is a frequently occurring task. In a data science project, manipulating data through loops will frequently require understanding how many items are being processed (i.e. counting). For this reason, it’s important to understand a simple and easy way to enable this. Python has many different ways to do that and in this article, we’ll go over a basic way to do that as well as more eloquent ways to go about counting operations.


I liken the crypto movement akin to another passion of mine, punk rock. It started from a very underground movement by those defiant and wanting to prove the establishment wrong. My only hope is that some of those original movers and the major influencers handle crypto differently than punk. It was truly a beautiful thing in the early days… Raw, Passion, Energy… Punk meant something, it moved people, and it scared those who didn’t understand it.
