On Nostr, for a public key that I subscribe to, how can I verify that my relays aren’t filtering out messages from that key? Is there a merkle hash on your latest note that I can use to verify that your previous notes were all received?
Nice interview of @craigraw about Sparrow Wallet on JavaFX in Action. Frank Delporte asks good questions about reproducible builds, JavaFX, etc and also gets an introduction to Bitcoin using the Sparrow UI.
secp256k1-jdk is a modern, functional-style Java API with two implementations for Java, JDK, GraalVM native-image, Kotlin, Scala, etc.
It aims to be the standard library for secp256k1 in the greater JDK/JVM Bitcoin ecosystem.
Thanks to Andreas Schildbach and @craigraw for their help!
