I've been looking for a tool to experiment with bitcoin script for a while now, and I finally finished developing one myself: https://bitauth.com/ide/

BitAuth IDE is an open source project for designing advanced scripts for bitcoin and bitcoin-like cryptocurrencies. It’s both a learning sandbox and a tool for designing new kinds of wallets.

It includes a live-updating, interactive, line-by-line debugger, which visualizes that state of the stack over the entire execution of the program. There's also an entity and variable system for automatically generating private keys, public keys, and correct signatures across locking and unlocking scripts.

See here for a more detailed tour and a video walkthrough:

And the source is on GitHub: https://github.com/bitauth/bitauth-ide

Hi there – my Bitcoin Wiki account is User:bitjson – I'd like to update the Script article to include links to some new open source development tools I just released:

BitAuth IDE — Write and Debug Custom Bitcoin Scripts: https://blog.bitjson.com/bitauth-ide-write-and-debug-custom-bitcoin-scripts-aad51f6e3f44

Could my account be verified? Thanks!

Just an old laptop

In case any new people are wondering, there is a topic in Meta about forum ranks called "Forum ranks/positions (What does those shiny coins under my name mean?)". Here's the link:

Are you?

It'd be interesting to get more votes- anyone else?

How long do threads like this normally float at the top of the forum?

Yep

Interesting pricing? Why such a steep opening level?

Is that actually safe? Paying via gift?

Ya, they're shipping now.

Except the governments are growing wary of free spaces at this point.

It can be trimmed though.

This is interesting.

Or not.

Takes a while.

They'll be given away over time.

Wise words.

Is there any way to determine how much Bitcoin has been orphaned like this?
