Correction · 1 October 2026. Unsourced historical price, hashrate and fee estimates were replaced with labelled scenarios. Miner subsidy revenue is no longer equated with an attack-cost estimate. The original publication date and URL are retained. This is a source-based editorial correction, not an independent security audit.
Subsidy issuance is computable from protocol parameters. Dollar revenue also needs prices and a time window. The cost of attacking the chain needs much more than either: accessible hardware, competing work, operating constraints and the attack being considered.
A target-rate issuance model
Litecoin targets 150-second blocks and halves its subsidy every 840,000 blocks. With a 6.25 LTC subsidy, the target-rate calculation is 86,400 / 150 × 6.25 = 3,600 LTC per day. Actual daily blocks vary. Halvings occur at heights, so calendar dates beyond an observed block are estimates.
| Halving height | LTC / block | Target-rate LTC / day |
|---|---|---|
| 2,520,000 | 6.25 | 3,600 |
| 3,360,000 | 3.125 | 1,800 |
| 4,200,000 | 1.5625 | 900 |
| 5,040,000 | 0.78125 | 450 |
Keep a dollar scenario explicit
At an illustrative $60/LTC and $0.10/DOGE, LTC subsidy revenue at the target rate is $216,000 daily. Dogecoin’s 10,000 DOGE subsidy and 60-second target imply 14.4 million DOGE, or $1.44 million daily. Combined model subsidy revenue is $1.656 million, of which LTC contributes about 13.0%.
If only the LTC subsidy halves, the combined model falls to $1.548 million: a 6.52% decline rather than 50%. This holds prices, block rates and participation fixed and excludes all transaction fees and other merged-mined coins. It does not forecast miner behavior.
Measure fees instead of guessing
To report a historical fee contribution, choose a complete set of blocks, sum their actual fees and record missing heights. Do not multiply an unsourced “typical block” by a day. Our network archive exposes observation coverage and distinguishes snapshot averages from transaction-weighted totals.
Revenue is not attack cost
Two networks with the same measured hashrate can have different economic risks. Equally, a reduction in dollar revenue does not specify how many miners exit or how much Scrypt capacity an attacker can acquire. Difficulty adjustment changes expected rewards per unit of work; it does not replenish revenue or make a safety guarantee.
Use the calculator for a machine-level stress case and the halving tracker for block-height progress. For current hardware and a frozen observed market input set, see the seven-configuration mining study.
