Lengthy-time Bitcoin developer Paul Sztorc has been attempting to overtake Bitcoin’s structure since 2015, however the broader neighborhood hasn’t budged.
So now he has proposed a dramatic step, referred to as eCash hardfork, that entails copying Bitcoin’s code to launch a separate model in August, whereas giving present bitcoin holders equal tokens within the new community totally free.
The neighborhood, nonetheless, is criticizing the funding half, which entails reassigning cash linked to Bitcoin’s lacking founder, Satoshi Nakamoto.
What’s a tough fork?
Consider a tough fork like a railway line splitting into two. Trains begin from the identical station, however sooner or later the road splits, serving to trains attain fully totally different locations.
When a bunch of builders can not attain consensus on a proposed change to Bitcoin’s code, they copy the present blockchain and launch it as a separate chain, which shares Bitcoin’s total historical past as much as the purpose of the break up, however diverges after the break up, transferring ahead with its personal guidelines, options, token and course.
That is exactly what occurred in 2017 when the talk over Bitcoin’s block measurement reached a tipping level, culminating in a series break up and the creation of the Bitcoin Money blockchain with its native token, BCH.
The technical dispute centered on Bitcoin’s 1MB block measurement restrict, which caps the variety of transactions that may be processed each 10 minutes when new blocks are added to the blockchain. Therefore, some favoured growing the block measurement, however the neighborhood remained divided, ultimately resulting in a series break up.
Sztorc’s eCash exhausting fork
The proposed exhausting fork will create a brand new chain referred to as eCash with native eCash tokens. “Maintain 4.19 BTC on the time of the fork, get 4.19 eCash. You may promote it, preserve it, or ignore it totally,” he mentioned on X.
The fork is scheduled for Bitcoin block peak 964,000 in August 2026. A coin-splitter device will probably be launched to assist holders cleanly separate their BTC from their new eCash.
The brand new chain will probably be a near-copy of Bitcoin’s present blockchain, with one important addition referred to as Drivechains, a scaling structure Sztorc first proposed in 2015 and formally submitted to Bitcoin builders as BIP300 and BIP301 in 2017 and 2019, respectively.
Drivechains are sidechains tethered to the Bitcoin blockchain, permitting seamless motion of BTC between the primary chain and sidechains with out altering Bitcoin’s base layer. Every sidechain can function beneath its personal guidelines and options, basically permitting builders to construct new capabilities on high of Bitcoin with out requiring your entire community to undertake these adjustments.
Consider Drivechains as service roads hooked up to the primary freeway. When the freeway is congested, drivers can exit the freeway and journey on the service highway at totally different pace limits, then re-enter the freeway when it is clear. This fashion, the freeway by no means adjustments, but extra visitors is dealt with extra effectively, and the journey turns into extra versatile for everybody.
Seven Drivechains are already in improvement, Sztorc mentioned on X, together with a privateness chain modelled on Zcash, a prediction market referred to as Truthcoin, a decentralised trade referred to as CoinShift, and a quantum-resistant chain referred to as Photon.
The controversial half linked to Satoshi cash
Sztorc needs to make use of cash that might have gone to Satoshi Nakamoto’s equal addresses on the brand new eCash chain to convey buyers on board earlier than the fork goes stay, a call he calls needed however which has riled the neighborhood, with some calling it outright theft.
A possible exhausting fork would convey Bitcoin’s total transaction historical past to the brand new chain. So each bitcoin steadiness, together with Satoshi’s 1.1 million bitcoin, sitting untouched in wallets which have noved moved these cash, would present up as an equal eCash steadiness on the brand new chain.
As per the plan, fewer than half of the Satoshi-equivalent eCash cash will probably be assigned to buyers as we speak. The exact mechanism of the way it’s being performed stays unclear. However since eCash would not but exist, the pre-hard fork assign appears to be a promised credit score following a profitable exhausting fork.
The plan, he argues, will guarantee collaborators have a tangible incentive to become involved early, constructing momentum and finishing work forward of launch. With out this mechanism, the venture can flip right into a “zombie venture” that ships unfinished. Worse, it may develop into a centralized venture, the place a small group of builders features outsized management over the chain’s course.
The business response, nonetheless, has been unfavorable.
“Taking Satoshi cash is theft and disrespectful, and eCash is already used for Lightning funds with Cashu and Fedi. These are poor decisions,” Bitcoin advocate Peter McCormack mentioned.
Josh Ellithorpe, chief know-how officer at Pixelated Ink, expressed considerations in regards to the precedent it units and the way it may ultimately be a threat to everybody’s BTC holdings.
“eCash, setting the precedent that they’ll and can steal cash. Now it is Satoshi, however it may very well be anybody later. Additionally misrepresenting the BCH fork, stealing one other venture’s title, and never having replay safety,” Ellithorpe mentioned.
