bitcoin cash fork fight

It’s judgment day for Bitcoin Cash.

After a vicious war of words between the two competing sides, Bitcoin Cash will execute a hard fork today and split into two separate blockchains. By the end of the day, we may have two new cryptocurrencies on the market:

Bitcoin Cash ABC and Bitcoin Cash SV.

However, the developers behind Bitcoin Cash SV do not expect the two new blockchains to live in harmony.

Bitcoin Cash SV: “The Intention is for Only One Chain to Survive”

Looking back to a press release issued earlier this month, the Bitcoin Cash SV camp explained clearly:

“With Bitcoin SV, we are not seeking to create a new Bitcoin variant and we are not intending to create a new Bitcoin SV token.”

The statement was issued by nChain, the software and development company behind the proposed SV upgrade. It continues:

“There will likely be a period of time before this temporary chain split is resolved, while miners are voting with their hash power.”

In other words, they believe only one chain should be allowed to exist after the fork: the longest one. That will simply be determined by how much hash power (or mining computer power) is directed to each chain.

“No Transaction Replay Protection” – a Technical Trip Wire

Transaction replay protection is a mechanism built into blockchains that makes transactions on one blockchain invalid on the other one.

Bitcoin Cash SV has not implemented this protection.

Without transaction replay protection, it means users can unwittingly lose money by accidentally transacting on the wrong chain. It also opens up holes for hackers to exploit.

It’s a sign of war from Bitcoin Cash SV. They expect the “losing” chain to peter out, with no protection needed.

If you’re a Bitcoin Cash holder, however, you need to be careful. The best advice is to keep your Bitcoin Cash safely in a wallet until the dust settles.

A Fight for Hash Power

If only one chain is to exist, it will come down to a fight over hash power. In other words, the decision lies with Bitcoin Cash miners: which upgrade will they devote their mining power to?

Indications suggest that Bitcoin Cash SV has the edge with at least 72% of estimated mining hash power compared to ABC’s 13%.

This also gives SV the potential power to initiate a 51% attack against the ABC blockchain. Craig Wright, the man behind SV has not ruled out this possibility. Miners could also mine “empty blocks” that don’t contain any transactions. It would effectively bring the blockchain to a halt.

What will happen?

It’s still too early to tell. However, there are three possible outcomes:

  1. Only one coin survives – As Bitcoin Cash SV hopes, a dominant chain could emerge and overwhelm the hash power of the other.
  2. Two coins emerge – If hash power is shared to a viable extent, there may be two concurrent blockchains and two separate cryptocurrencies.
  3. Implosion – There’s a chance that the vicious infighting and nefarious hashing actions could kill the value of both blockchains and endanger the entire future of Bitcoin Cash.

The Bitcoin Cash debate rages on as we approach Thursday’s hard fork.

There’s a very real possibility that Bitcoin Cash, as we know it, will split into two separate cryptocurrencies.

The two camps are deeply divided over technical (and political) disagreements. This isn’t just a debate over algorithm changes, it’s a fight over the true vision of bitcoin.

So who’s winning?

Well, it depends on how you look at it.

Traders Are Backing the Bitcoin Cash ABC Project

Thanks to Poloniex – a crypto exchange which opened up pre-fork trading on both coins – we know that traders value Bitcoin Cash ABC about four-times higher than rival Bitcoin Cash SV.

Traders are currently pricing BCHABC at $390.

But they’re only pricing BCHSV at $111.

It’s a fairly clear indicator that traders are throwing their weight behind ABC. ABC is backed by bitcoin.com‘s Roger Ver, mining giant Bitmain and most large third-party service providers.

But Bitcoin Cash SV May Have More Miner Support

While traders are important in the debate, so are Bitcoin Cash miners.

Bitcoin Cash miners will have to choose which version of the upgrade they migrate to on November 15th, and early indications suggest Bitcoin Cash SV might have the edge.

The largest Bitcoin Cash mining pools, including CoinGeek, BMG Pool, okminer, mempool, and SVPool, have publicly backed Bitcoin Cash SV. 

Translated into hash power, the current estimates look like this:

Bitcoin Cash SV has at least 66% of estimated hash rate.

Bitcoin Cash ABC has at least 18% of estimated hash rate.

The numbers come from CoinDance’s hash power charts.

Hash power simply refers to the amount of computer power dedicated to cryptocurrency mining at any one time. If the majority of hash power is directed at one side of the fork, we can infer it has more support from miners.

In other words, it looks like miners might back SV.

These Figures are Estimates

It’s important to remember that figures on both sides of the debate are estimates.

Poloniex trading figures are based on a hypothetical market with relatively thin trading volume.

And the CoinDance hash estimates are based on how mining pools have indicated their support. Miners themselves won’t necessarily follow the public statements of their pools.

Bitcoin Cash ABC and Bitcoin SV Explained

Bitcoin Cash ABC – Lays the groundwork for enormous scaling in the future. Keeps the block size the same, while building functionality for new features like atomic contracts. Backed by Roger Ver, Bitmain, and supported by Coinbase, Binance, and other large third-parties.

Bitcoin Cash SV – Claims to be the true Bitcoin vision (or “Satoshi Vision”). Technical updates include a larger block size to improve transaction speed. Backed by Craig Wright, nChain, CoinGeek and a large portion of BCH mining pools.
