A Bitcoin miner using Braiins Solo found block 970,904 on October 11, earning a block worth about 3.129 BTC before the service’s fee structure. The block itself is independently verifiable on-chain, and its coinbase data includes the /braiinssolo/ tag.
The block was mined at 09:58:22 UTC and contained 844 transactions. Public block data shows a standard 3.125 BTC subsidy plus 0.0039865 BTC in transaction fees, for a total coinbase reward of 3.1289865 BTC — roughly $260,000 at Bitcoin prices around the time of discovery.
The most important verification is not a social post or a mining-company claim. The Bitcoin block itself records the hash, timestamp, transactions, subsidy, fees and the /braiinssolo/ coinbase identifier.
The winning hardware is still unknown
Public block data can prove that the block was mined through the Braiins Solo path, but it does not reveal the winning miner’s exact ASIC model or hashrate. Third-party solo-mining trackers currently list the device and hashrate as unknown.
That distinction matters. Solo mining stories often spread with dramatic claims about a tiny home miner beating industrial farms, but those claims should only be made when the miner or service provides verifiable hardware details. For block 970,904, the safe conclusion is narrower: Braiins Solo found the block; the exact machine behind the winning share has not been publicly verified.
BitcoinVersus has covered other unusual solo-mining outcomes, including a NiceHash user finding two Bitcoin blocks only four blocks apart and three solo-mined Bitcoin blocks landing within 22 hours.
Braiins Solo lets miners aim for the full block reward
Braiins describes its Solo service as a way to connect owned miners or purchased hashrate and attempt to find a Bitcoin block without participating in the normal pooled-reward model. If a connected miner finds a valid block, the service says the block reward is paid directly to that miner minus a 0.5% pool fee.
That does not change the underlying probability problem. A miner’s chance of finding a block is still proportional to its share of total Bitcoin network hashrate. Buying more hashrate increases the probability, but it does not guarantee a result during any specific rental window or mining session.
The block carried very little fee revenue
Block 970,904 collected only 0.0039865 BTC in transaction fees, compared with the fixed 3.125 BTC subsidy. That means fees represented only about 0.13% of the block reward.
This is a useful reminder that today’s miner revenue is still dominated by the subsidy when fee pressure is low. BitcoinVersus recently explained how the Bitcoin block subsidy works and why it falls every 210,000 blocks.
Block 970,904 arrived less than four minutes after the previous block
The previous Bitcoin block, 970,903, was timestamped at 09:54:28 UTC. Block 970,904 arrived at 09:58:22 UTC, only 3 minutes and 54 seconds later. Bitcoin targets roughly ten minutes per block over long periods, but individual block intervals can be much shorter or much longer because proof-of-work discovery is probabilistic.
The network difficulty associated with the block was about 132.7 trillion. That is consistent with BitcoinVersus’ recent coverage of Bitcoin difficulty near 132.76T and the growing importance of ASIC efficiency.
What is confirmed
Bitcoin block 970,904 is confirmed on-chain with hash 000000000000000000016d3757f864a84f128ba95e5bb883904546a4ecb1c862. It contains the /braiinssolo/ coinbase tag, 844 transactions, a 3.125 BTC subsidy and 0.0039865 BTC in transaction fees.
What remains unconfirmed is the winning miner’s exact hardware, physical location and hashrate. Until Braiins or the miner publishes those details, claims about whether this was a tiny home ASIC, a larger private fleet or rented hashrate should be treated as speculation.
Editor’s Note: Block details were checked against independent Bitcoin block data. Braiins Solo attribution comes from the coinbase tag itself; hardware and hashrate claims are intentionally omitted because they are not presently verifiable.
