Calculate and analyze BSV mining difficulty from targets, bits, and network data.
# Get current network difficulty
bun run skills/calculate-mining-difficulty/scripts/difficulty.ts --current
# Calculate from compact bits (e.g., genesis block)
bun run skills/calculate-mining-difficulty/scripts/difficulty.ts --bits 0x1d00ffff
# Calculate from target hex (64 characters)
bun run skills/calculate-mining-difficulty/scripts/difficulty.ts --target 00000000ffff0000000000000000000000000000000000000000000000000000
# JSON output for scripting
bun run skills/calculate-mining-difficulty/scripts/difficulty.ts --bits 0x1d00ffff --json

Mining Difficulty Analysis
==========================
Difficulty: 1
Target: 0x00000000ffff0000000000000000000000000000000000000000000000000000
Bits: 0x1d00ffff
Expected hashes: 4.29e+9
JSON output (--json):
{
"difficulty": 1,
"target": "00000000ffff0000000000000000000000000000000000000000000000000000",

The script uses the standard Bitcoin difficulty formula:
0x00000000FFFF0000000000000000000000000000000000000000000000000000 (difficulty 1)max_target / current_targettarget = mantissa * 2^(8*(exponent-3))difficulty * 2^32Uses WhatsOnChain API for current network data:

This skill should be used when the user asks to integrate "Yours Wallet", "connect a BSV wallet", use "BRC-100", "pay with BSV wallet", add "wallet checkout in a web app", use "yours-wallet-provider", build a "pay with Yours Wallet" button, access "window.CWI", or connect a React app to a BRC-100 wallet.
This skill should be used when the user asks to "decode transaction", "parse tx hex", "transaction details", "analyze transaction", "decode BEEF", "parse BEEF hex", "decode EF transaction", "inspect transaction", or needs to decode BSV transaction hex (raw, Extended Format, or BEEF) into human-readable format.
This skill should be used when the user asks to "lookup address", "check address balance", "address UTXOs", "address history", or needs to retrieve BSV address information from WhatsOnChain API.
This skill should be used when the user asks to "broadcast transaction", "submit to ARC", "broadcast via ARC", "broadcast BEEF", "broadcast EF", "use GorillaPool ARC", "use TAAL ARC", "arc.gorillapool.io", "arc.taal.com", "ArcConfig", "broadcastMany", or needs to submit a signed BSV transaction to the network using the ARC broadcaster from @bsv/sdk.
This skill should be used when the user asks to "post to BSocial", "like a post", "unlike", "follow user", "unfollow", "send message", "repost", "friend request", "on-chain social media", "BMAP", "BSocial protocol", "channel message", "create on-chain post", "read BSocial posts", or needs social operations (posts, likes, follows, messages, reposts, friends) on BSV blockchain.
Explicit-only installer for the BSV Skills David Codex custom agent. Use ONLY when the user explicitly asks to install, update, check, uninstall, or set up the BSV Skills, David, or Bitcoin Codex agent, including "install David in Codex", "update the BSV Skills Codex agent", or "check bsv_skills_bitcoin". Never auto-invoke for ordinary BSV, Bitcoin, wallet, transaction, identity, mining, or blockchain requests.
