BOOK: A Beginner's Guide To Bitcoin Focused Web Development

Greetings All,  For the past year I have been working on a book that aims to fill the gap of Bitcoin focused web development instruction. So few resources are available in this space which is what led to me to put this project together. The book is now out and available on Amazon: https://www.amazon...

Beginners guide to bitcoind and JSON-RPC API

Hey All, I just finished a new tutorial series on using bitcoind and JSON-RPC API. If understanding bitcoin itself isn't difficult enough, integrating and using a bitcoin server on a website takes it to another level. I hope someone finds it useful. 1.

Re: Check out my $85 Raspberry Pi Bitcoin full node

I think 1GB of RAM will not be enough for another decade. Even now some of these pi nodes have issues when their mempool grows. Personally I'd recommend getting a refurb PC off amazon for $60 with 4 GB RAM and 3GHZ processor. More power will cost more power, but at least you won't have to worry abou...

Re: Total number of outputs

I think what you are looking for is gettxsetinfo This query takes a while considering the amount of data it needs to parse through your node. I just tried to run it and it still hasn't populated after 200 seconds, but this is an example of what it should look like. { "height" : 225494, "bestblock" :...

Re: Is the Australian Craig Wright the real Satoshi?

After reading the gizmodo article and interviews I don't see how anyone could say that Dr Wright is satoshi. If it were anyone in the mentioned interviews it was Dave Kleiman. Satoshi does not need to be found, and bitcoin is better off as a myth.

Very nice guys! I'm excited to try out V2 of the receive payments API. I like the integration with HD pubkeys, it will make a merchant's transactions a lot more private than the previous version that always forwarded to the same address. I've put in my request for an API key. :mrgreen:

Hey Andreas!

One time you mentioned that you started with youtube videos, and you gained a following from there, is that correct?
Are any of your early-day youtube posts still available? Would you share the link of some of your first bitcoin videos?

Happy to break even? No, no, no... Invest a sum that doesn't bother you if the price were to crash and then hold it for a long long time.
