For those of you not familiar with Jameson Lopp's extensive writing on the topic of email centralization, I recommend reading this post from his blog: "The death of decentralized email: A historical review of the multi-decade centralization and capture of the email protocol." https://blog.lopp.net/death-of-decentralized-email/

Well yes, that's the intended audience of that article. If you want to understand the tech, Mastering the Lightning Network is an excellent resource, although it's obviously a heavy read. For something between the book and a wikipedia article, try Jameson Lopp's site, starting with the Getting Started section: https://www.lopp.net/lightning-information.html

Jameson Lopp has a nice section in his Bitcoin resources site: https://www.lopp.net/bitcoin-information/security.html Look, e.g. at the Cold Storage section, If you are truly paranoid, then follow this protocol: https://glacierprotocol.org/
BelenusMordred · 2021-07-09
> SEO blog article The writer is Jameson Lopp. There's good solid advice in there for anyone, not just crypto holders, yes he's promoting his own company but it's a big stretch of the imagination to say the bloke is some SEO spammer. https://www.lopp.net/

Bitcoin is already storing over $1.1 trillion of the world's wealth which would currently put it in the top 10 global assets [1], as well as the top 10 global currencies based on M1 money supply [2]. It is also the best performing asset over the past 10 years [3]. It appears to already be a store of value.

Jameson Lopp has put together a great list of resources for those looking to get started in the space. - https://lopp.net/bitcoin.html

https://lopp.net/bitcoin.html Great resource that covers a array of topics on a spectrum of levels for different audiences.

> Yet there is the belief that you can somehow create a coherent experience into a “whatever”. Whatever it is actually. My first mastodon instance was de-federated by accident from my current instance. I moved to that instance though because many other hackers in the Open Source space did, and unlike Fosstodon it seems to allow non English content which I do care about quite a bit. (After all my life and household is multilingual and I don't live in an English speaking country.) Yet that instance still defederates qoto and I'm guessing because qoto permits unpopular opinions and does not block servers itself. Given the history of email, I'm surprised there hasn't been more about the economics of spam, blacklists, and so on. Substitute the email-specific parts of the following article with Mastodon-specific terms and concepts, and it doesn't paint a very pretty picture. https://blog.lopp.net/death-of-decentralized-email/

> It still seems like a valid metric, you just need to multiply the number of bitcoin transactions with some factor for the average number of outputs Nah. You don't need to double and triple down on wrong ideas and metrics that are scientifically spurious. You know calculus so you know multiplying by averages won't tell you what you want to know. Transaction count relative to energy usage doesn't tell you what's valuable about the observed system and its energy consumption, which is its decentralisation, censorship resistance, assurances, and trustlessness. Assuming you care about logic, simply update your broken mental model. Because batching will increase as Bitcoin grows, and has practically infinite throughput, its efficiency improves exponentially by securing more value relative to energy consumption.To secure ever more value using the Bitcoin network, humans are incentivised to find and build more efficient energy sources. Further, an arbitrary number of transactions can occur securely offchain and get aggregated and finalised on-chain i.e the settlement layer. In fact this is how the future will be. See Lightning, Liquid, other L2 designs. The order of operations is first to have a bulletproof settlement layer. Bitcoin was designed to be the single planetary currency. Spend time studying it and you'll realise that Satoshi was smarter than all his current critics who all imagine they've brilliantly and uniquely perceived some fatal flaw in Bitcoin's engineering,…

Articles such as https://blog.lopp.net/metal-bitcoin-seed-storage-stress-test/ will help you pick among the various seed stores out there.

Agree. I am so happy that Dorsey's other open protocol (nostr) went another route. There is no 'official' client, there is just a whole bunch of competing clients, some of which have even attracted some small funding strategies to maintain a development team for the forceable future. But none of these clients are big enough to push through locked-in features. They all have to play nice (for now, like SMTP and IMAP once did) and be interoperable. For info, check out Lopp's blog: https://blog.lopp.net/why-nostr-matters/

Whisper is way better than at least some other transcription solutions: https://blog.lopp.net/open-source-transcription-software-comparisons/

They're probably just referring to the (historically decreasing) variance in time between blocks, nominally 10 minutes. Not an outage by any stretch but occasionally annoying. It's smoother in higher frequency blockchains. https://blog.lopp.net/bitcoin-block-time-variance/

> It's bad for the environment Not any more so than other forms of energy consumption. If anything, Bitcoin incentivizes the use of clean renewable energy. https://niccarter.info/topics/ > bad for crime Hard to even parse what that means given how much crime is committed via dollars. https://unchained-capital.com/blog/bitcoin-is-not-for-criminals/ > bad for laymen Meaningless drivel. > undemocratic (vote with money) Bitcoin is both undemocratic AND is not a "vote with money" type of system. Governance is unrelated to who holds it. https://www.lopp.net/bitcoin-information/governance.html > no knobs to adjust monetary/fiscal policy That's a feature. > it poses as an alternative to government institutions that serve society with things like roads and health care. Also a feature. https://www.coincenter.org/a-human-rights-activists-response-to-bitcoi…

That's exactly what's happening. Decentralized, trustless version is the Lightning Network, https://www.lopp.net/lightning-information.html

for bitcoin, there is plenty here: https://www.lopp.net/bitcoin-information.html once you're up to speed on bitcoin, you're ready for smart contracts. i'd suggest looking up Sergey Nazarov on youtube and watching his interviews in order from oldest to newest. that will give you the basics to go from there

If you're going to transact with a particular person a lot, if you're both on LN, transactions take seconds and the cost is negligible: https://www.lopp.net/lightning-information.html

Start by reading about the technology you want to use and develop with. I would suggest Jameson Lopp's pages about bitcoin[0]: [0]: https://www.lopp.net/bitcoin-information.html

If you want to start hacking right away: I started with setting up my own Bitcoin/Lightning node with LND/BTCD, since I was a little more comfortable in the Go ecosystem. Nowadays I would probably use Bitcoind since it is the de facto standard. As a wallet I often hear about Wasabi and Samourai to be relatively comfortable. If you want to read/listen first, there are some good podcasts, e.g. Stephan Livera. And Jameson Lopp has a good collection of links for every purpose https://www.lopp.net/bitcoin-information.html . Bitcoin development is focussed on building a maximally decentralized store of value and thus rather careful. Only if you do not care about monetary value and just want to play around with crazy ideas that may or may not prove useful in the future, take a look at Ethereum or one of the other altcoins.

Here's about 150 links to get you started: http://lopp.net/bitcoin.html The arguments for digital cash have been laid out since the cypherpunk days of the early '90s. Go read True Names: and the Opening of the Cyberspace Frontier for the philosophical underpinnings.

Shamelessly stolen without credit from Jameson Lopp's ( https://twitter.com/lopp ) long-running resource list http://lopp.net/bitcoin.html I can't believe someone would do such an obvious copy-paste without crediting the creator and think no-one would find out. Pitiful.
