Recently, ViaBTC announced its support for merged mining of Bitcoin (BTC) and Fractal Bitcoin (FB), further increasing the earnings of BTC miners. FB is a scalability solution on the Bitcoin network, utilizing the same mining algorithm as Bitcoin. This allows BTC miners to switch over and participate in FB mining seamlessly.
Merged mining is a vital aspect of the FB mining process. In the following analysis, we will detail the expected increase in earnings for BTC miners under this, providing users with a clearer understanding of their recent earnings composition.
Bitcoin has a block generation time of ~10 minutes. Following this year’s fourth halving, the block reward stands at 3.125 BTC. Calculations indicate a theoretical daily output of 144 blocks × 3.125 BTC = 450 BTC. With the Bitcoin price at $63660.23 on September 23, the daily value of BTC is approximately $28.65 million.
As of September 23, Bitcoin’s hashrate is 635.44 EH/s, which translates to daily earnings of about 0.0000007 BTC per TH/s of hashrate, valued at roughly $0.0451.
To enhance scalability, FB has reduced the block generation time to one block every 30 seconds. Notably, FB mining is divided into permissionless mining, which requires BTC miners to switch their hashrate to FB, and merged mining, which allows BTC miners to earn additional FB rewards simultaneously. According to FB’s difficulty adjustment mechanism, the block generation ratio for permissionless mining compared to merged mining is approximately 2:1.
FB offers a block reward of 25 FB, with halving events occurring roughly every two years; the next one is anticipated around August 2026. Thus, the current theoretical daily output for FB is 72,000 FB, with 48,000 FB from permissionless mining
