Regardless of bitcoin (BTC) hitting a brand new all-time excessive this weekend of $122,000, the protocol’s blockspace worth is at an all-time low, with demand to transact and retailer knowledge on-chain trending towards a single satoshi or “sat,” value a paltry 1/100 millionth of 1 BTC.
Actually, transaction charges have endured at such a low stage that some builders and node operators are manually overriding their minimal price acceptance charge to permit customers to bid for lower than a single satoshi.
Particularly, they need to enable friends to bid lower than $0.17 for the standard 140 digital byte (vByte) Native Segwit transaction.
One sat is a default minimal so low that Core builders have not often thought it essential to decrease it — till now.
On Friday, for instance, the typical transaction price per BTC transaction was lower than $1.19 — together with the total mixture of low, medium, and excessive precedence bids from all customers of the Bitcoin community.
Loads of customers had transactions within the mempool bidding absolutely the minimal of a single satoshi per digital byte.
Yr so far, demand for blockspace has bottomed out to its worst common charge in years.
Common price per BTC transaction in USD (through BitInfoCharts).
Decrease the mempool minimal beneath a single satoshi
Comically, it’s considerably tough as a node operator to relay transactions with these embarrassingly low price charges.
“I don’t want to be forced to pay a 25-cent fee on a completely empty mempool,” wrote senior Bitcoin developer Calle, “if I could have paid five cents.”
Bitcoin developer SuperTestnet agreed, “I am okay with relaxing this filter.”
Nevertheless, really modifying Bitcoin node software program to simply accept bids of, say, $0.05 as an alternative of $0.17 requires slightly little bit of coding ability.
Node operators can modify the minimal price per vbyte by adjusting their minRelayTxFee variable inside their Bitcoin Core software program. Actually, they will settle for and relay transactions bidding a price cheaper than even one cent.
At present, the default worth for minRelayTxFee in Bitcoin Core is 0.00001 BTC per kilo digital byte (kvB), which is equal to at least one satoshi per vByte.
A node operator could specify a fair decrease minimal through the startup parameter -minrelaytxfee= or the configuration parameter minrelaytxfee=.
Minimal demand for blockspace
In fact, the default worth itself issues. Some builders are even contemplating proposing a modification of this default for upcoming releases of Bitcoin Core software program.
Nevertheless, there isn’t a proper pull request (PR) for this variation, neither is there consensus on activating any such change.
Bitcoin’s mempool (queue of transactions ready to be processed) is sort of utterly empty. The proportion of miner income coming from charges (as an alternative of inflation) is right down to a fraction of a %. 😱

Word that the dialogue about accepting bids of lower than one satoshi is just related for mempool coverage — the queues of pending transactions relayed between nodes world wide.
The Bitcoin protocol itself will settle for validly mined transactions with any bid quantity — together with zero-fee transactions. Blockspace demand and costs for knowledge storage are in the end on the discretion of miners.
Certainly, miners sometimes settle for cost out of band to mine transactions with 0 BTC in on-chain transaction charges.
Nonetheless, through the common course of day-to-day enterprise, miners principally select transactions from main mempools such because the default Bitcoin Core mempool.
