A leading cryptographer, the inventor of hashcash, which is used in the Bitcoin (BTC) mining process, says it is time to call time on satoshis, the units that make up a bitcoin.

With BTC prices soaring sky-high in recent weeks, the CEO of the blockchain technology firm Blockstream, Adam Back, has taken to Twitter (where else?) to opine that satoshis (or sats for short) have had their day.

“Bitcoin is too expensive, but sats are too many, sound cheap and confusing.”

Back, who was one of the first two people to receive an email from Satoshi Nakamoto, is one of the many early Bitcoin architects who some claim may be Nakamoto himself – the (presumably) pseudonymous author of the original Bitcoin white paper.

Whereas foundering fiats make use of easier to understand units (such as cents to the dollar, pence to the pound, and so on), things are not so straightforward in the bitcoin world.

The general unit structure of bitcoin has 1 bitcoin (BTC) equivalent to 1,000 millibitcoins (mBTC), 1,000,000 microbitcoins (μBTC), or 100,000,000 satoshis.

But Back, who favors dividing bitcoin by 1 million units instead, explained,

“Satoshis are confusing […] Sats were designed by Satoshi to be bitcents under bits. One million is much easier than [a] 100 million base. Even bitcoin-qt (core) had bits for years. You still have sats, just bits and bitcents (aka sats), like dollars and cents.”

@Xentagz Why not both. Introducing to wider audience did you know 1bit is 100sat. Bitcoins are logically enough mad… https://t.co/4CnVRvoixg

I couldn't agree more. Sats have always seemed too small and abundant to reason about. Dividing by 100 mil is also much less natural than dividing by 1 mil.Using bits, every wholecoiner is a millionaire, and that feels just right. It's time we all start stacking bits.

But as satoshis are so hard to understand for most, it can be “hard to figure out what you bought” when investing in bitcoin, wrote Back, who urged that it was now “time for a reboot” on denominations.

And dreaming, like many bitcoin HODLers, of a day when BTC hits the USD 1 million mark, he wrote,

“[It] sets a nice parity target at USD 1 mil per BTC where USD 1 = 1 bit and 1 bitcent = 1 satoshi = 1cent.”

Back concluded with a flourish, adding some (anecdotal) Nakamoto lore, claiming,

“Story I heard from early developers, was [fellow Bitcoin OG and possible Nakamoto Hal Finney] persuaded Satoshi it wasn't enough for world population, and so Satoshi added 1 million divisions, moving the new bitcent to 1/100th bit.”
