Get current network difficulty

获取当前网络难度

bun run skills/calculate-mining-difficulty/scripts/difficulty.ts --current

Calculate from compact bits (e.g., genesis block)

通过压缩位计算（例如创世区块）

bun run skills/calculate-mining-difficulty/scripts/difficulty.ts --bits 0x1d00ffff

Calculate from target hex (64 characters)

通过目标值十六进制字符串计算（64个字符）

bun run skills/calculate-mining-difficulty/scripts/difficulty.ts --target 00000000ffff0000000000000000000000000000000000000000000000000000

Difficulty Math

难度计算原理

The script uses the standard Bitcoin difficulty formula:

Max target:

0x00000000FFFF0000000000000000000000000000000000000000000000000000

(difficulty 1)

Difficulty:
```
max_target / current_target
```
Compact bits format: First byte = exponent, next 3 bytes = mantissa
- ```
target = mantissa * 2^(8*(exponent-3))
```
Expected hashes:
```
difficulty * 2^32
```

该脚本使用标准的比特币难度计算公式：

最大目标值：

0x00000000FFFF0000000000000000000000000000000000000000000000000000

（难度值为1）

难度值：
```
最大目标值 / 当前目标值
```
压缩位格式：第一个字节=指数，后3个字节=尾数
- ```
目标值 = 尾数 * 2^(8*(指数-3))
```
预期哈希量：
```
难度值 * 2^32
```
