The highly anticipated vote on Bitcoin's scaling solution concluded recently, resulting in a significant reduction in the immediate risk of a chain split. This development was met with a swift and robust price recovery for Bitcoin, which saw a weekly surge of up to 53%. Despite this positive outcome, the risk of a fork is not entirely eliminated, with market analysts pointing to early August as the next critical period to watch.
The Reduced Likelihood of a Bitcoin Hard Fork
Market participants closely monitored the voting process throughout the week as the threat of a Bitcoin split loomed. The growing miner support for the BIP91 proposal, designed to prevent a blockchain split in early August, led to a broad market consensus that the immediate risk was receding. This sentiment was a key driver behind the stabilization and subsequent rise in Bitcoin's price.
In a significant development, F2Pool, one of the highest hash rate mining pools, confirmed the successful activation of the SegWit2x upgrade. Data from voting trackers showed that by a key deadline, the SegWit2x proposal had achieved a support rate exceeding 90%. This level of consensus is widely interpreted to mean that a disruptive hard fork is now highly unlikely and that the network will instead undergo a smooth upgrade via a soft fork.
A hard fork occurs when a change to the protocol's rules is not backward-compatible. This results in the blockchain splitting into two separate chains, forcing miners to choose which one to support. In contrast, a soft fork is a backward-compatible upgrade. Older nodes continue to operate on the network, accepting blocks created by new nodes, thus avoiding a chain split. The ultimate outcome around August 1st will be determined by the collective choices made by miners and users regarding which software version they run.

Bitcoin Price Poised for a New Rally
Following the positive news, Bitcoin's price experienced a significant uptick. At one point, the price reached $2,690, representing a 24-hour gain of over 15%. On domestic Chinese exchanges, the price surge was even more pronounced, with values skyrocketing by 13% to nearly 20,000 yuan per coin, approaching previous all-time highs. After this peak, the price corrected slightly but remained firmly above 18,000 yuan.
The previous week had witnessed a broad sell-off across the cryptocurrency market due to the uncertainty surrounding the fork. Data from major exchanges indicated that from its recent peak, Bitcoin's price had fallen by as much as 39%. This downturn also dragged down other major digital assets like Litecoin, Ethereum, and Ethereum Classic.
Industry experts noted that while Bitcoin was the originator of the sell-off, it demonstrated relative resilience compared to other cryptocurrencies, underscoring its leading status and perceived store of value. As the highest-valued decentralized digital asset, Bitcoin often acts as a benchmark for the entire sector, with its price stability serving an "anchoring" function for the broader market.
With the scaling concerns temporarily alleviated, digital currency prices have begun to rebound. Bitcoin's price has swiftly recovered its recent losses this week. Market analysts suggest that after this short-term consolidation phase, where weak hands were shaken out, the stage is set for a potential new upward trend.
Major Exchange Announces Service Pause
The next significant milestone is August 1st. In preparation for potential network instability, Huobi, one of the largest Bitcoin trading platforms, released a statement outlining its contingency plan. The exchange announced that it will temporarily suspend Bitcoin deposit and withdrawal services around 8:00 AM on August 1st. This precautionary measure is intended to protect users from potential transaction rollbacks and replay attacks that could occur during a chain split.
The exchange clarified that services will be reinstated once the network is deemed stable, provided no fork occurs. In the event that Bitcoin does split into one or multiple new assets, Huobi has committed to crediting users' accounts with an equal amount of each new forked coin. Furthermore, the platform stated that if a split appears inevitable, it will gradually enable trading for all new Bitcoin variants.
Frequently Asked Questions
What is the difference between a hard fork and a soft fork?
A hard fork is a radical change to a network's protocol that makes previously invalid blocks and transactions valid, often resulting in a permanent divergence from the previous version of the blockchain. A soft fork is a backward-compatible upgrade where only previously valid transactions are made invalid, and all nodes recognize the new blocks as valid, avoiding a chain split.
Why did Bitcoin's price surge after the SegWit2x vote?
The high rate of miner support for SegWit2x significantly reduced the immediate risk of a contentious and disruptive hard fork. This reduction in uncertainty restored investor confidence, leading to increased buying activity and a rapid price recovery as the market anticipated a smoother scaling solution.
What should I do with my Bitcoin before August 1st?
If you hold Bitcoin in your own private wallet, you will possess any potential new coins that result from a fork. If your coins are on an exchange, check their official policy regarding forks. Many major exchanges, like Huobi, have promised to support users by distributing all forked assets. For the safest approach, consider moving your coins to a wallet where you control the private keys before the critical date.
Will the scaling debate be completely resolved after this?
While the BIP91 activation is a major step forward, the scaling debate is complex and long-standing. This solution, SegWit2x, involves a two-part process. The second part, a block size increase, is scheduled for later this year and could potentially lead to further discussion or even a new fork if consensus isn't reached.
What are replay attacks and how do they occur?
A replay attack can happen after a blockchain splits. A transaction broadcast on one chain might be valid and also broadcast on the other chain, effectively duplicating the transaction. This could lead to a loss of funds if you intended to only transact on one chain. Exchanges暂停 services to prevent this.
How does Bitcoin's volatility compare to other cryptocurrencies?
While all cryptocurrencies are volatile, Bitcoin is generally considered one of the more stable assets within the digital currency space. It often experiences smaller percentage swings during market downturns compared to smaller altcoins, acting as a relative safe haven, though it remains a high-risk asset overall.
