Paul Sztorc’s proposed eCash fork is often described as a battle over the fundamental principles of Bitcoin. However, developers and infrastructure builders view it differently.
They argue that this isn’t truly a Bitcoin fork but rather an airdrop — one with potential hazards. Sergio Lerner, co-founder of Rootstock Labs, told CoinDesk via email, “I’m firmly against Paul’s fork, not because it is a ‘hostile Bitcoin hard fork,’ as some claim. eCash represents a new blockchain… It does not directly impact bitcoin holders.” This distinction helps to alleviate much of the initial criticism. Unlike previous splits that sought to use the Bitcoin name or vie for hashpower, eCash resembles more closely a token being distributed to existing Bitcoin holders.
However, Lerner and others argue this reframing merely shifts rather than resolves concerns. While airdrops are common in crypto, they remain rare and often problematic within Bitcoin.
Lerner highlights the operational risks tied to distributing eCash based on Bitcoin’s UTXO set — the collection of “unspent transaction outputs” that constitute user balances. This approach could expose users to unnecessary risks if they attempt to claim tokens, particularly since it might require them to move funds out of cold storage and interact with unfamiliar software.
The absence of full replay protection between the two chains further complicates matters. Without a clear separation, transactions intended for Bitcoin could inadvertently affect funds on eCash, or vice versa. Dan Held, a Bitcoin entrepreneur, bluntly noted: “Reallocating Satoshi’s coins is shock value marketing, and the lack of replay protection makes it quite hazardous to redeem.”
Lack of replay protection allows valid, signed transactions from the fork to be maliciously broadcast and accepted on another chain, leading to duplicate unwanted transactions on both networks. This can result in accidental loss of funds if two chains share the same transaction format.
The distribution method itself is under scrutiny. Bitcoin ownership often passes through exchanges, custodians, and institutional platforms, meaning those holding private keys are not always the economic owners of the coins.
“Custodians controlling UTXO keys frequently aren’t the rightful economic owners,” Lerner stated. This situation can disadvantage users who hold bitcoins through custodians — some may never receive eCash, while others face new risks to access it. For systems like sidechains (including Rootstock) and federated custody networks built on Bitcoin, this could necessitate coordination or upgrades to safely divide coins across chains.
Lerner also criticized the project’s funding model for allocating Satoshi-linked coins from the new chain to early investors, labeling it as “morally objectionable and unnecessary.”
For others like Jay Polack, head of strategy at Bitcoin sidechain VerifiedX, the proposal reflects a broader trend of attempting to reinterpret Bitcoin’s core properties through derivative systems.
“It’s mind boggling to think that anyone would consider this a good idea,” Polack remarked about combining forking and reassigning dormant coins. He argues that even indirect changes in how Bitcoin ownership is represented risk undermining its core guarantee: “You can’t break the native ownership of Bitcoin. It’s totally contradictory to what Bitcoin is.”
In this view, eCash is less about altering Bitcoin itself — it doesn’t change — and more about whether the ecosystem should accept structures that reinterpret its ledger.
While most Bitcoin forks fail to gain traction, eCash might follow suit. Yet, the response to it clarifies something else: Bitcoin’s resistance to change isn’t solely about code or consensus rules. It encompasses expected user behavior, risk introduction, and acceptable experimental boundaries at the edges.
When framed as an airdrop, eCash appears less like a challenge to Bitcoin — more like a test of how far its social boundaries actually extend.
