‘Bitcoin is not facing an assault: BTC advocates dispel concerns of a DoS attack’

25

A sudden increase in Bitcoin () transaction fees and unconfirmed transactions raised alarms on Crypto Twitter over the weekend regarding a possible Denial of Service (DoS) “attack” on the network.

Several Bitcoin analysts and commentators have promptly reassured their followers about these concerns.

The average transaction fees for Bitcoin are currently $19.20, or 0.00068 BTC, as reported by BitInfoCharts. At the same time, Mempool Space indicates that the transaction backlog stood at 459,341 at the time of writing.

This heightened demand on the network has even led to total fees per block temporarily surpassing the block subsidy reward of 6.25 BTC on May 7.

The proof-of-work mining mechanism has a fixed block subsidy of 6.25 BTC, which is halved every four years. However, in rare cases of surging block space demand, this amount can be surpassed, resulting in elevated transaction fees.

Industry analysts noted that this is the first occurrence of such an event since 2017. Fees of 6.76 BTC were recorded for one block, while block 788695 generated fees of 6.7 BTC.

The Mempool Space explorer indicates that activity has since moderated somewhat, and fees have dropped back below the block reward. The upcoming block is anticipated to process generating 4.51 BTC in fees.

The increase in activity and demand for block space has been linked to the rise in Ordinals inscriptions. Analytics provider Glassnode reported that 75% of Bitcoin on-chain transactions utilized Taproot on May 7, marking a record high.

Some users on Crypto Twitter, however, speculated that the recent congestion was due to a DoS (denial of service) attack on the Bitcoin network.

Bitcoin analysts quickly clarified that the situation was a result of demand rather than a coordinated attack. “0xfoobar” informed his 130,000 followers:

“Bitcoin mempool finally gets some usage and the maxis are framing it as a DoS attack on the network. They really have not considered even the most basic scenarios, like ‘Bitcoin becomes popular and people are willing to pay to use it’”

On May 8, the largest cryptocurrency exchange, Binance, once again suspended Bitcoin transactions, citing “the large volume of pending transactions.” This marks the second instance in which Binance has halted BTC transactions within the last 12 hours.
