Thresholds are measured in annual VBWD-attributable sales, valued at the year’s average BTC/USD. Non-production use — development, testing, evaluation and education — is always free.
Your annual VBWD-attributable sales — the revenue your VBWD-based product generates, not your company’s total revenue.
The threshold is a Bitcoin quantity valued at the arithmetic average of the daily BTC/USD price over the reporting year, so a single day’s volatility can’t push you over the line.
Always. Development, testing, evaluation and education are unlimited and free regardless of the threshold.
Yes. Under BSL 1.1 each release converts to the permissive Apache-2.0 licence on its change date.
