Ethereum pushed through a hard fork to return funds to users caught in The DAO contract exploit. Mining power shifted to the new chain almost at once. Some Bitcoin block-size advocates seized the moment to argue that hard forks pose less risk than critics claim. But one factor remains: market pricing only emerges once exchanges start trading the divergent chains.
Token holders began trading the original chain, now called Ethereum Classic, through Bitsquare and Bitcointalk before Poloniex added it. The split gave speculators an arena to value each chain. Ethereum Classic now controls about 12 percent of the hashrate and market cap compared to the forked version.
The comparison to Bitcoin hard fork debates misses a central point, according to Peter Todd, a Bitcoin Core contributor. "Ethereum isn't fixing something technical – they're doing a bailout of a company [or] group that screwed up," Todd told MiningPool. "Nothing in this bailout hard fork actually fixes anything technical."
Bitcoin's community operates from a different premise. The network's core value flows from its function as bearer cash—digital assets held without intermediaries. Rewriting transaction history, as Ethereum did, violates that purpose. Bitcoin has weathered major thefts. Bitfinex lost tens of millions in bitcoin months ago. No one proposed reversing the chain.
"Bitcoin has already gone through huge thefts and hacks, and none of it has been reversed," said Eric Lombrozo, a Bitcoin Core contributor and CEO of Ciphrex. He pointed to MyBitcoin as an example from Bitcoin's early days. "Hard forks weren't even on the table back then. It was actually a force of frustration for me in the early days because I wanted to do a bunch of cool stuff that didn't seem possible without a hard fork. But then I learned more about how things actually work."
The taboo against hard forks cut deep. "It was practically taboo," Lombrozo said. "Nobody would take you seriously if you started going in that direction. Everyone basically accepted that doing it would require coercion in some form or another and that, unless everyone agreed, it could lead to disaster."
Developers and contributors understood the stakes. A hard fork creates a new coin by default. Bitcoin Wiki lists potential hard-fork changes, showing the community knows such splits remain feasible whenever significant groups of miners, developers, and users want to branch off.
This possibility creates two structural problems. A chain split fragments bitcoin itself, diminishing what should operate as digital gold. Second, majority factions gain power to force minorities into accepting changes. "It's a really, really tough battle for the weaker chain," Lombrozo said.
Ethereum Classic shows that ideological differences can support two competing chains. The situation continues to develop. Privacy upgrades like widespread coin mixing could prevent mob-driven hard forks. But Bitcoin's monetary policy and block sizes remain vulnerable to hard-fork attempts anytime.
Bitcoin develops at deliberate speed. Critics say the pace lags behind what's needed. The actual risk differs: rushing development courts disasters like The DAO. Bitcoin maintains its focus on bearer cash. Core developers add smart-contract features with restraint, avoiding the complexity that enabled The DAO disaster.
Development has accelerated throughout 2016 despite perceptions otherwise. The community settled on a basic roadmap by late 2015. These advances have shipped: libsecp256k1 delivered 7x faster signature verification. CHECKSEQUENCEVERIFY activated. BIP 9 (Version Bits) enabled Bitcoin's first soft fork using the mechanism. Segregated Witness merged into Bitcoin Core, awaiting activation. The Lightning Network approaches completion for mainnet deployment once Segregated Witness activates. Rootstock opened private beta for an Ethereum-style Bitcoin sidechain. Matt Corallo, a Bitcoin Core contributor and Blockstream Core Tech Engineer, unveiled the Fast Internet Bitcoin Relay Engine (FIBRE) for near-zero-delay block relay between nodes. Bitcoin Core 0.13 introduced Compact Block Relay to trim redundant data transfers among nodes.
These represent key milestones among many others. Segregated Witness and the Lightning Network rank as the two most significant developments. "Development on Bitcoin is going at a very fast pace – there's probably the equivalent of two or three dozen developers working on Bitcoin Core full time and more if you include things like the Lightning Network," Todd said. "Sure, part of the community isn't getting what they want, but progress is still being made at a fast pace."
Bitcoin commands a larger installed base than Ethereum. Protocol changes gain easier adoption when the user base stays narrow and unified. "Unlike Bitcoin, Ethereum gets very little real-world use of any kind," Todd said. "People aren't using ether to move money across borders, people aren't paying for stuff on dark-markets with ether, people aren't making donations, etc. The DAO was nearly the only actual production app on Ethereum – and it itself was pretty alpha. Getting consensus to change networks that aren't actually getting used in production is quite a bit easier than changing ones that are because the lack of use-cases means there's going to be less differing incentives among different players."
Bitcoin users resist reversing blockchain transactions to preserve bearer cash principles. Bitcoin's scripting stays simple, reducing risks that demand "bailouts" like The DAO. The platform's success means real users stand to lose from splits or contentious hard forks. A hard fork itself proves nothing. The surrounding context determines its meaning.
Bitcoin's resistance to hard forks may signal genuine success. Decentralization itself makes consensus on protocol changes difficult to achieve. Experimental features encounter obstacles. But valuable improvements—CHECKLOCKTIMEVERIFY and CHECKSEQUENCEVERIFY both arrived—gain adoption over time. Sidechains like Rootstock enable testing without changing the main chain, separating speculation from core uses.
In public blockchains, unlimited adaptability cuts both ways. When protocol changes happen with minimal resistance, the network risks drifting from the foundational principles that generated its value.
