These 27 Companies Support Bitcoin Unlimited, 44 Oppose

While bitcoin Unlimited is gaining traction among miners, only a handful of bitcoin companies are in favor of its bigger block and Emergent Consensus proposal.


Breakdown by Company

The scaling debate in which two predominant bitcoin improvement proposals, SegWit and bitcoin Unlimited, are competing for miners’ support is becoming more and more intense.

As the debate escalates, supporters from both sides are now threatening to push for user activated forks (both soft and hard). While bitcoin Unlimited is considered the most popular proposal in terms of hashing power, a look at the companies that support it or SegWit reveals the exact opposite.

As of this writing, out of the companies listed in Coin Dance, 66 support SegWit and 58 are ready for it. Only 8 companies oppose SegWit.

On the BU side, there are 27 in favor, with 9 companies ready for it. This means that 70% of companies actively support SegWit, compared to 20% for BU. The other 10% are undecided or “unknown”. The companies that support BU include:

  • AntPool
  • Atlanta bitcoin
  • BitAddress.org
  • bitcoin.com (Saint Bitts LLC)
  • BitcoinPlug
  • Bitmain
  • BTCPOP
  • Canoe
  • Coinucopia
  • GoUrl.io
  • bitcoin WordPress/PHP Gateway
  • Keys4Coins
  • MrCoin
  • Slon BTM
  • Bitfire.io
  • Bittoku GK
  • btc.top
  • GBMiners
  • Keyois
  • Prohashing
  • Satoricoin
  • ViaBTC
  • Bitzillions
  • Magnr
  • Bitaps.com
  • CTY bitcoin Vietnam TNHH
  • OKCoin
  • Trezor (Ready)
  • Electrum (Ready)
  • bitcoin Wallet for Android (Ready)
  • Bifinex (Ready)
  • Breadwallet (Ready)
  • Gemini (Ready)
  • Lamassu (Ready)
  • Rocketr (Ready)

It should be noted that even among the 9 companies that are ready for BU, two also support SegWit (Electrum and Trezor) and 5 are ready for SegWit (including Bitfinex and Gemini). 

It’s also worth noting that some of the companies that are against bitcoin Unlimited are not even supporting SegWit. They are simply opposed to BU’s Emergent Consensus.

Meanwhile, 4 of the 8 companies that oppose SegWit and are all signaling for BU are mining pools.

Who Supports What?

We can see that some predominant exchanges like Poloniex, LocalBitcoins, CoinCheck and others are ready for SegWit, while other names like BTCC, Xapo and Bitso support it.

On the BU side, in addition to bitcoin.com, Magnr, BitAddress.org, and several BTM providers, the biggest names by far are mining pools such as Bitmain’s Antpool, ViaBTC and GBMiners. However, the independence of these mining pools has recently come under question by the community.

At the same time, the only major exchanges that support BU also support SegWit, including OKCoin, Bitfinex (ready) and Gemini (ready).

The companies that actively oppose SegWit include 4 mining pools and 4 other small companies that don’t have much bearing in the bitcoin ecosystem. Conversely, among the companies that oppose BU actively, we find names like BitGo, Vaultoro, Bitsquare, and GreenAddress.

Among the undecided, we still have names like Bitstamp, Bittrex, Bitmex, Kraken, and others.

bitcoin Businesses Generally Against BU, Hard Fork

The general animosity towards bitcoin Unlimited can also be observed in the industry letters that have been signed so far. For example, a list of nearly 20 exchanges has signed a hard fork contingency plan in which the BU token would be listed as BTU or XBU.

Canada’s bitcoin ecosystem has also produced an industry letter in which a large number of economic nodes operators signaled their rejection for BU and proposed industry guidelines for hard forks.

Moreover, the data is also reflected (despite varying data depending on the course) by the share of bitcoin Core (84-91%) nodes among total network nodes compared to bitcoin Unlimited’s (2-9%).

The conclusion that can be draw from this data is that despite the growing popularity of bitcoin Unlimited among mining pools, bitcoin companies as well as user nodes are largely opposed to the bitcoin Unlimited proposal.

Alex Tapscott’s Nextblock Global Receives Major Backlash Prior to Public Offering

Things have gone from bad to worse for Alex Tapscott this past week. Several of his projects have received a lot of scrutiny. Moreover, there are some allegations which have to be rectified as well. Nextblock Global, the company owned by Alex Tapscott, will invest in companies and projects focusing on ICOs. However, the list of advisors for this company is mostly fake. Not a big surprise, but it is still rather worrisome.

Most people in the cryptocurrency world know the name Alex Tapscott. He is a well-known author and Canadian investors. However, his latest business venture raises a lot more questions than answers. Nextblock Global is a very dubious business model, to say the least. Not because of the investing angle, but everything else about it seems pretty fake. Especially the list of alleged advisors contains names which aren’t even associated with this venture.

Trouble Ahead for Nextblock Global

Some of those names include Andreas Antonopoulos and Dmitry Buterin. It is unclear why their names are on the list of advisors, to begin with. Neither of these gentlemen is even remotely connected to this new venture. There are some other names on the page which may also be completely fake, including Vinny Lingham and Kathryn Haun. It is disconcerting to see these names listed on a site they don’t even want to be associated with. It is a common tactic among semi-scammy ICO ventures, though.

The big question is why Alex Tapscott made such a grave mistake. It is evident these names were included to make the company more legitimate. However, it is unclear if this is his doing or someone else’s. The official explanation is how they were “listed in a draft version”. Even so, these names shouldn’t be there unless they agree to be a part of it. A weak explanation, to say the very least. This doesn’t bode well for the future of Nextblock Global either.

It is evident this whole ordeal will cause a lot of heated debate. The Canadian Imperial Bank of Commerce has rebuked its underwriting of the Nextblock Global public offering. This is the only logical decision as long as these “issues” are still being discussed. It is a very strange and potentially unfortunate turn of events. Whether or not there was any foul play involved, will always remain a question. It won’t do the reputation of Alex Tapscott any favors either right now. Then again, if this is an error, it should all blow over pretty soon.
