Rare event or minor strategy?

According to Mempool data, Bitcoin mined 954,352 empty blocks high.

This block contained only Coinbase transactions. That is, it included miners’ rewards, but not regular user transactions.

This block was mined by SpiderPool. Mempool data showed timestamp 2026-06-19 04:27 and block weight 1.16 kU.

Short block gap attracts attention

The empty block occurred approximately 62 seconds after the previous Bitcoin block. This short gap is the main reason why traders and network watchers were alerted to this event.

Fast block gaps can leave miners stuck using a Coinbase-only template before a more complete transaction template reaches the mining hardware. This can result in valid empty blocks.

Empty Bitcoin blocks, on the other hand, are nothing new. In June 2024, Mempool Research noted that while empty blocks have appeared throughout Bitcoin’s history, such blocks are now rare.

The study explains that mining pools may send blank templates. The reason is that templates are smaller and faster to send. The trade-off is that miners waive transaction fees from that block.

Repeated actions become more important

A single empty block does not indicate a problem with the Bitcoin network. We do not stop payments, reverse trades, or break consensus rules.

If empty blocks appear repeatedly, the event becomes more significant. This could raise new questions about miners’ timing choices and whether some pools are prioritizing speed over fee income.

As previously reported on crypto.news, miner timing incentives have been discussed in research on selfish mining risks. This empty Bitcoin block is not the same as selfish mining, but it adds another data point for analysts monitoring miner behavior.

Furthermore, as covered by crypto.news in 2022, Bitcoin SV faced an empty block issue, but that case involved a different network and a more serious pattern. In the case of Bitcoin, block 954,352 is best read as a rare but known mining event, unless the pattern continues.
