Sats are the unit of sound money while ksh is the unit being measured.

1. 21 Million Supply Limit
Bitcoin’s total supply is capped at 21 million BTC. This comes from the block reward halving schedule:
Initial block reward: 50 BTC
Halving every 210,000 blocks (~4 years)
Total BTC = sum of geometric series:
total_btc = 0
block_reward = 50
halving_interval = 210000
while block_reward > 0:
total_btc += block_reward * halving_interval
block_reward /= 2
print(total_btc) # Should output 21000000
2. Block Size Limit
Originally, Bitcoin had a 1 MB block size limit (set by Satoshi). Transactions in a block cannot exceed this limit.
MAX_BLOCK_SIZE = 1_000_000 # bytes
def is_block_valid(block):
return block.size <= MAX_BLOCK_SIZE
3. Difficulty Adjustment
Bitcoin adjusts the mining difficulty every 2016 blocks (~2 weeks) to keep the block interval ~10 minutes.
Formula:
\text{New Difficulty} = \text{Old Difficulty} \times \frac{\text{Actual Time of Last 2016 Blocks}}{20160 \text{ minutes}}
If blocks came too fast → difficulty ↑
If blocks came too slow → difficulty ↓
def adjust_difficulty(prev_difficulty, actual_time_seconds):
target_time = 2016 * 10 * 60 # 2016 blocks * 10 minutes per block
new_difficulty = prev_difficulty * (actual_time_seconds / target_time)
return new_difficulty
4. Block Interval (~10 minutes)
Bitcoin targets a 10-minute interval between blocks.
This is enforced indirectly via mining difficulty: miners must solve Proof-of-Work (PoW) hashes under the target.
Formula for target hash:
\text{hash} \leq \text{target}
import hashlib
def mine_block(data, target):
nonce = 0
while True:
hash_result = hashlib.sha256((data + str(nonce)).encode()).hexdigest()
if int(hash_result, 16) <= target:
return nonce, hash_result
nonce += 1
5. Consensus Rules for Valid Transactions
A transaction is valid if it meets Bitcoin’s rules:
1. Inputs reference unspent outputs (UTXOs)
2. Input amounts ≥ output amounts
3. Signatures are valid
4. ScriptPubKey conditions satisfied
5. No double-spending
def is_tx_valid(tx, utxos):
input_sum = 0
output_sum = 0
for inp in tx.inputs:
if inp.utxo not in utxos:
return False # input does not exist
if not verify_signature(inp.signature, inp.utxo.pubkey):
return False # invalid signature
input_sum += inp.utxo.amount
for out in tx.outputs:
output_sum += out.amount
if input_sum < output_sum:
return False # trying to create coins out of nothing
return True

If consensus fails, Bitcoin loses integrity.

You trust the bank with your life savings. They don’t even trust you with a pen. #Bitcoin fixes this.
