Absolutely (or relatively) sure that you know how timelocks in #Bitcoin work?

In my latest blog for @QalaAfrica I discuss the different types of timelocks in Bitcoin, and their application in the #LightningNetwork ⚡

Check it out 👇

If you self custody your Bitcoin then you almost certainly have come across a mnemonic phrase of 12 or 24 words.

What is a mnemonic?
Why do I have one?
How does it work?

I’ve been working on Bitcoin for almost a decade, let me break it down for you 👇

[bitcoin-dev blog @bitcoindevblog]

Hello World! https://t.co/6pdk6rSx0i is a technical and open content blog for and by Bitcoin developers.

We start with a deep dive into compact block filters written by @ElleMouton!

New year, new blog post.

@kallerosenbaum dives into the Schnorr signature scheme. He shows why nonces must be secret, why you shouldn't reuse them, and why the challenge needs to have all three of 𝓡, 𝓟, and 𝓶 .

Don't be too afraid of the light math!

⚛️I made my own Quantum Random Number Generator.

It uses radioactive decay to generate entropy for #Bitcoin seeds.

I used:
- Americium 241 from a Smoke Detector
- RaspberyPi
- Geiger counter
- Audio interface.

Entropy is what makes a bitcoin your bitcoin.

psa, for the ~15 amazing people already running bitcoin nodes with an I2P service, consider restarting them on current master following this merge, which would allow testing it with several peers running an I2P service before the release https://t.co/UOZELpDa2N

How to get from entropy to a #Bitcoin address.


The picture has laid out every step. 

I will just clarify what is being done in each step or why things are done.

This is the cryptography in Bitcoin.
