Bitcoin has faced two very different fork events this August.
One involved BIP-110, a controversial proposal designed to temporarily restrict certain types of non-financial data stored on Bitcoin. That attempt has already resulted in a small chain split that quickly stalled.
The other is a planned eCash hard fork, expected around Bitcoin block 964,000, which would deliberately create a separate blockchain based on Bitcoin’s transaction history.
Both are described as “forks,” but they are not the same thing.
Understanding the difference is important because the word fork can make it sound as though Bitcoin itself is about to break in two or that every BTC holder needs to take immediate action.
That is not necessarily the case.
First, What Is a Bitcoin Fork?
Bitcoin is software.
Thousands of computers around the world run software that follows a shared set of rules. Those rules determine things such as which transactions are valid, how blocks are created and what other computers should accept as part of the Bitcoin blockchain.
Sometimes developers or users want to change those rules.
If everyone agrees on the new rules and upgrades in a compatible way, the network can continue operating as one blockchain.
But sometimes different groups want different rules.
That is where a fork can happen.
An easy way to think about it is a road that reaches a junction.
For years, everyone travels along the same road. At the junction, one group continues straight while another takes a different route.
Both roads share the same history before the junction, but from that point onward they can lead in completely different directions.
Blockchain forks work in a similar way.
There are two terms that frequently appear when discussing forks: soft fork and hard fork.
What Is a Soft Fork?
A soft fork introduces stricter rules while trying to remain compatible with older versions of the software.
Imagine an existing rule says vehicles up to 10 tonnes can use a road.
A new rule reduces the limit to five tonnes.
Anything that satisfies the new five-tonne limit also satisfies the old ten-tonne limit.
That is roughly the principle behind a soft fork.
Nodes enforcing the new rules accept a narrower set of transactions or blocks than nodes using the older rules.
Bitcoin has successfully used soft forks for major upgrades before.
However, a soft fork can still cause a chain split if some participants begin rejecting blocks that most miners and users continue accepting.
That is exactly why BIP-110 became so controversial.
What Is a Hard Fork?
A hard fork changes the rules in a way that is not compatible with the existing network.
Instead of everyone continuing under the same set of rules, a group can deliberately create a separate blockchain.
The new chain usually copies the history of the original blockchain up to a specific block and then begins operating under its own rules.
Bitcoin Cash is probably the best-known example.
In 2017, disagreement over Bitcoin’s block-size rules resulted in Bitcoin Cash splitting away from Bitcoin. Research into the event describes the August 2017 split as producing the original Bitcoin network, BTC, and the separate Bitcoin Cash network, BCH.
That history helps explain what the planned eCash fork is trying to do.
The First August Event: BIP-110
BIP-110 stands for Bitcoin Improvement Proposal 110 and is formally called the Reduced Data Temporary Softfork.
The proposal was created to temporarily restrict some methods used to insert large amounts of arbitrary data into Bitcoin transactions.
The official BIP-110 specification says its goal is to limit data fields at the consensus level and refocus Bitcoin on its role as money.
Supporters have argued that Bitcoin should primarily be used for financial transactions rather than permanent storage of images, inscriptions and other arbitrary data.
The debate became particularly relevant following the rise of Ordinals, inscriptions and token-related protocols that use Bitcoin block space in ways some participants consider unnecessary.
Critics of BIP-110 took the opposite position.
They argued that if users are willing to pay the required transaction fees, miners should generally be free to include those transactions in Bitcoin blocks.
The disagreement was therefore about more than technical limits.
It became a broader debate over what Bitcoin should be used for and who gets to decide.
What Was BIP-110 Trying to Change?
BIP-110 proposed several temporary restrictions on transaction data.
Among other changes, the proposal would restrict some large arbitrary-data fields and certain script structures that its supporters believe are primarily being used for non-monetary data storage.
Importantly, the proposal was designed to be temporary.
According to the BIP-110 deployment specification, the restrictions would remain active for roughly one year before expiring unless another change was introduced.
The proposal also included an unusual activation mechanism.
It set a miner-signalling threshold of 55%, significantly lower than thresholds traditionally associated with some earlier Bitcoin soft-fork deployments.
If sufficient voluntary signalling did not occur earlier, BIP-110 would enter a mandatory-signalling period beginning at block 961,632.
That is where things became interesting.
BIP-110 Has Already Produced a Chain Split
The BIP-110 event is no longer merely something expected later in August.
The crucial moment arrived on August 8, 2026, when Bitcoin reached block 961,632.
Nodes enforcing BIP-110 began rejecting blocks that did not signal support for the proposal.
Most Bitcoin miners, however, continued mining according to the existing Bitcoin rules.
The result was a chain split.
The BIP-110 minority chain managed to mine only two blocks in roughly eight hours, while the main Bitcoin blockchain continued advancing normally.
The split therefore did not produce two comparably strong Bitcoin networks.
The overwhelming majority of mining power remained with the existing Bitcoin chain.
Why Did the BIP-110 Chain Stall?
Bitcoin mining becomes difficult because the network adjusts how much computational work miners must perform to produce blocks.
The BIP-110 branch inherited Bitcoin’s existing mining difficulty.
But it did not inherit anything close to Bitcoin’s total mining power.
That created a severe problem.
With only a very small amount of hash power working on the BIP-110 branch, producing additional blocks at Bitcoin’s existing difficulty became extremely slow.
Recent reporting found that BIP-110 had received only around 2.5% miner signalling before the split, far below the proposal’s 55% voluntary threshold.
The BIP-110 chain therefore fell rapidly behind while Bitcoin continued functioning normally.
The official BIP specification has since been updated to mark BIP-110 as Closed, specifically noting that the change followed a chain split with stalled mining.
The BIP-110 fork event happened, but it did not replace the existing Bitcoin network.
Does the BIP-110 Failure Affect Your BTC?
For someone simply holding or sending ordinary Bitcoin, the dominant Bitcoin network has continued operating normally.
The stalled BIP-110 branch does not automatically change your BTC balance on the main Bitcoin blockchain.
The larger significance is about Bitcoin governance.
Bitcoin has no central company that can simply announce a software update and force everyone to use it.
Developers can write proposals.
Node operators can choose software.
Miners can choose which valid blocks to mine.
Users, exchanges and businesses can decide which network they recognise as Bitcoin.
BIP-110 provides a particularly clear demonstration of what happens when a group attempts to enforce new consensus rules without enough mining support.
The software can create a different branch.
But keeping that blockchain alive requires miners, infrastructure, users and economic activity.
The Second Event: The eCash Hard Fork
The other planned August fork is very different.
Bitcoin developer and LayerTwo Labs CEO Paul Sztorc has proposed a hard fork called eCash, targeting Bitcoin block 964,000.
Unlike BIP-110, the intention here is not to persuade the entire Bitcoin network to operate under the new rules.
The plan is to create a separate blockchain.
eCash is described as a near-copy of Bitcoin that would share Bitcoin’s blockchain history until block 964,000 before continuing independently.
That makes it much closer to what happened when Bitcoin Cash split from Bitcoin.
What Happens to BTC When eCash Forks?
If the fork proceeds as proposed, Bitcoin itself does not disappear.
Suppose you hold 1 BTC at the moment the snapshot occurs.
On the existing Bitcoin blockchain, you would still have your 1 BTC.
The new eCash blockchain would copy Bitcoin’s historical ledger and could therefore recognise an equivalent balance associated with the same historical ownership.
In simple terms:
1 BTC remains 1 BTC on Bitcoin.
And the forked chain could give you approximately:
1 eCash on eCash.
That does not mean your money automatically doubles.
The market would separately decide whether eCash has any meaningful value.
A forked token could become valuable, remain worth very little or fail to develop a liquid market altogether.
Why Is eCash Being Created?
The eCash project is closely connected to Sztorc’s long-running work on Drivechains.
Drivechains are designed to allow additional blockchains, known as sidechains, to operate alongside Bitcoin.
Different sidechains could experiment with features that Bitcoin itself does not support at its base layer.
Proposed Drivechains include concepts related to privacy, prediction markets, decentralised trading and even quantum-resistant functionality.
Sztorc has spent years pushing for Drivechains through proposals including BIP-300 and BIP-301.
They have not been adopted by Bitcoin’s broader development community.
The eCash fork effectively provides another path: instead of waiting for Bitcoin to adopt Drivechains, launch a separate Bitcoin-derived blockchain where they are included.
There Is a Controversial Satoshi Nakamoto Issue
One part of the eCash proposal has attracted considerable criticism.
When a blockchain is copied during a hard fork, historical balances are generally copied too.
That would normally mean addresses believed to belong to Bitcoin creator Satoshi Nakamoto would also receive equivalent balances on the new chain.
Satoshi is widely believed to control a very large amount of early-mined Bitcoin that has remained dormant.
The eCash proposal would reportedly treat some of the corresponding forked eCash differently.
The plan would leave about 600,000 eCash associated with Satoshi-linked addresses while redirecting around 500,000 of the forked-chain coins to investors supporting development of the new project.
That has generated criticism because some Bitcoin supporters believe even a forked network should preserve historical ownership exactly.
There is an important distinction, however.
None of this moves Satoshi’s actual BTC.
The proposal only concerns coins created on the new eCash blockchain.
Bitcoin private keys and balances on the existing Bitcoin network would remain governed by Bitcoin’s existing rules.
Is This the Same eCash as XEC?
No, and this could create considerable confusion.
There is already a cryptocurrency called eCash, commonly known by the ticker XEC.
That cryptocurrency developed from Bitcoin Cash ABC.
Sztorc’s planned Bitcoin fork is a separate project despite using the same eCash name.
Anyone reading about the August fork should therefore be careful not to assume that references to Sztorc’s proposed eCash automatically refer to the existing XEC cryptocurrency.
Could eCash Replace Bitcoin?
Technically, anyone can create a fork of Bitcoin.
The much harder challenge is convincing people to use it.
A successful cryptocurrency network needs more than working code.
It needs miners, wallets, exchanges, developers, businesses, liquidity and users.
Bitcoin Cash demonstrates what can happen when a fork develops enough support to survive independently.
It has continued operating since the 2017 split.
But BTC remained the overwhelmingly dominant chain associated with the Bitcoin name and ecosystem.
The eCash fork could similarly survive as a separate network, but launching a hard fork does not automatically give it Bitcoin’s users, market value or network effect.
Does Every Bitcoin Holder Automatically Get eCash?
This requires an important distinction between being entitled to forked coins and actually being able to access them.
If you hold Bitcoin in your own wallet and control the private keys at the time of a hard fork, the same keys can potentially correspond to balances on both chains.
If your BTC is sitting on an exchange, however, the exchange controls the private keys.
The exchange therefore decides whether it will support the fork, recognise the new asset and distribute corresponding coins to customers.
Some exchanges support major forks.
Others do not.
There is no rule requiring every exchange to list or distribute every new Bitcoin fork.
Do You Need to Move Your Bitcoin Before the eCash Fork?
For most BTC holders, there is no reason to move Bitcoin simply because a hard fork is scheduled.
Your Bitcoin remains on the Bitcoin network.
The more important issue is how you store it.
People who control their own private keys potentially have greater control over assets created through a fork.
People holding BTC through a custodial exchange depend on the exchange’s fork policy.
But chasing forked coins can introduce security risks.
Be Extremely Careful With “Claim Your eCash” Websites
Whenever a major blockchain fork happens, scammers have an obvious opportunity.
They can create websites claiming:
“Enter your seed phrase to claim your free eCash.”
That should immediately raise concern.
Your Bitcoin recovery phrase controls your Bitcoin.
Anyone who gets it can potentially steal the BTC in your wallet.
You should never provide your Bitcoin seed phrase or private key to an unknown website, app or person simply to claim a forked cryptocurrency.
It may be safer to wait until reputable wallets, exchanges and the project itself publish clear technical guidance after the fork rather than rushing to claim a token immediately.
There is rarely a good reason to risk valuable BTC just to access an uncertain forked asset.
Why Are These Two Events Being Grouped Together?
Mostly because they both involve disagreements over Bitcoin rules and both were scheduled around August 2026.
But technically they are very different.
BIP-110 attempted to introduce stricter rules onto Bitcoin through a soft-fork mechanism. Nodes enforcing those rules split away from the dominant network when most miners refused to follow them. The resulting minority chain stalled after two blocks.
eCash, by contrast, is intentionally designed to become a separate blockchain. It does not need the existing Bitcoin network to adopt its Drivechain rules for the new chain to launch.
That distinction is probably the most important thing to understand about the two events.
What Bitcoin Holders Should Watch Next
The BIP-110 episode has largely answered its immediate question.
The dominant Bitcoin network continued without adopting the BIP-110 rules, while the minority branch stalled.
Attention now shifts toward block 964,000 and whether the planned eCash launch actually proceeds as announced.
Bitcoin holders should watch for announcements from their own wallets and exchanges rather than assuming every platform will treat the fork the same way.
It will also be worth watching whether the new eCash chain attracts meaningful mining power, exchange support and liquidity after launch.
Creating a blockchain is one thing.
Creating a blockchain people actually want to use is another.
