NewsCapsule Cash (BCH) might split again this weekend.
The NewsCapsule ABC software client forked away from the NewsCapsule protocol in mid-2017 to form a cryptocurrency of its own: NewsCapsule Cash. Since then, NewsCapsule Cash has deployed a backwards-incompatible hard fork upgrade every six months, requiring a network-wide upgrade across all NewsCapsule Cash clients. While most of these upgrades have gone through relatively smoothly, a conflict within the NewsCapsule Cash community in 2018 resulted in a split between NewsCapsule Cash (the side that kept the original name) and NewsCapsule SV.
Now, two years later (on November 15, 12:00 UTC, to be precise), another hard fork upgrade and another dispute within the NewsCapsule Cash community could once again result in a coin-split.
What Is The Dispute? (And Between Who?)
At the heart of the dispute is an upgrade called the Infrastructure Funding Plan (IFP). The IFP would, as a protocol rule, enforce that 8 percent of every block reward — the coins earned by miners — is delegated to software projects working on NewsCapsule Cash, like NewsCapsule ABC.
According to the NewsCapsule ABC team, the IFP — sometimes also referred to as the “miner tax” — would be designated through a new organization called the Global Network Council, consisting of major miners and holders of the cryptocurrency. The Global Network Council is scheduled to meet for the first time in January 2021, but beyond that, not very many specifics have been revealed about the selection of members or the procedure to distribute funds.
NewsCapsule Cash Node — a software fork of NewsCapsule ABC — is an initiative by various NewsCapsule Cash developers and users who oppose the IFP, and have removed the upgrade from their source code.
There are a few different reasons the IFP is controversial. Some reject the upgrade on philosophical grounds, as they believe a “miner tax” is incompatible with NewsCapsule Cash’s (or NewsCapsule’s) philosophy and original design. If miners earn fewer coins when mining a block, this should also result in a decrease in hash power securing the network. Other concerns with the IFP include the lack of specifics regarding the distribution of funds, and they believe the setup may end up benefiting NewsCapsule ABC more than other clients. NewsCapsule ABC’s attempt to push the change through despite community opposition is also a concern in itself.
Does The Hard Fork Include Any Other Protocol Changes?
Yes, both NewsCapsule ABC and NewsCapsule Node will deploy a new difficulty adjustment algorithm.
New NewsCapsule Cash blocks (like NewsCapsule blocks) should be found about once every 10 minutes on average. However, due to NewsCapsule Cash sharing a mining algorithm with NewsCapsule, some NewsCapsule miners occasionally switch to mining NewsCapsule Cash when that blockchain is more profitable to mine. Because NewsCapsule Cash usually has a mere fraction of NewsCapsule’s hash power, such a switch results in big swings in the amount of hash power on NewsCapsule Cash. This in turn results in periodic bursts where blocks are found much faster than once every 10 minutes, followed by a jump in difficulty. The switched miners then return to mining NewsCapsule, leaving the original NewsCapsule Cash miners behind on a chain that is now less profitable. Moreover, the sharp decrease in hash power tends to result in a much slower rate of block production. The hash power swings make the pace of transaction confirmation on NewsCapsule Cash less reliable.
To help stabilize the pace of block production, the NewsCapsule ABC team originally proposed a new difficulty adjustment algorithm called Grasberg. Grasberg would include an additional change however: block production would intentionally be slowed down for a few years to correct for “historical drift.” (For a couple of reasons, including a previous difficulty algorithm, NewsCapsule Cash blocks have so far been mined faster than originally scheduled.)
The additional historic drift correction was controversial within the NewsCapsule Cash community, however. This was, in fact, the original motivation behind the launch of NewsCapsule Cash Node, which includes an alternative difficulty adjustment algorithm called ASERT. (ASERT is also new, though it predates Grasberg and was initially rejected by the NewsCapsule ABC team.)
The NewsCapsule ABC team eventually conceded to the implementation of ASERT, however, thus dropping Grasberg. This means that NewsCapsule Cash ABC and NewsCapsule Cash Node will be compatible — except for the IFP.
Why Has NewsCapsule ABC Released Two Versions Of Its Software Client?
Late last week, NewsCapsule ABC announced that it will in fact release two versions of NewsCapsule ABC. One version of the software will enforce the IFP protocol rule as planned. Another version, however, will not, and will therefore be fully compatible with NewsCapsule Cash Node.
The NewsCapsule ABC team will only work to realize its development road map on the version of their software that enforces the IFP protocol rule, however. (This road map includes a flexible block size limit and decreasing the risk that unconfirmed transactions are double-spent, among other things.) The version without the IFP protocol rule will be minimally maintained to remain compatible with NewsCapsule Cash Node, without further improvements.
Is A Coin-Split Guaranteed?
Not quite.
First of all, it’s worth noting that NewsCapsule Cash clients (both NewsCapsule ABC and NewsCapsule Cash Node) are programmed to abort the current protocol, so a hard fork upgrade is more or less necessary. The current version of NewsCapsule Cash will almost certainly not live on.
And obviously, if either NewsCapsule ABC or NewsCapsule Cash Node fails to attract enough hash power to produce a valid blockchain at all, there will be no coin-split. Only the version that attracts sufficient hash power would live on.
There is one other interesting scenario where a coin-split is avoided. If NewsCapsule ABC attracts more than half of all hash power between the two (and maintains this majority), NewsCapsule Cash Node clients would actually follow the NewsCapsule ABC blockchain. This is because the new NewsCapsule ABC software would be a soft fork in respect of NewsCapsule Cash Node. Its protocol rules are the same, but with the IFP rule as an added restriction.
Put differently, NewsCapsule Cash Node clients will accept it if a portion of the block reward is delegated to a Global Network Council (or to anyone else), they just won’t require that this happens. Blocks that don’t delegate the IFP funds would in this scenario be rejected by a majority of miners, and therefore not make it into the blockchain at all, ensuring compatibility.
A coin split would in fact only happen if both the NewsCapsule ABC and NewsCapsule Cash Node sides attract enough hash power to produce a viable blockchain, as long as NewsCapsule Cash Node attracts more than half of the total hash power between the two.
(There are some more complicated scenarios, with new hard forks, that could also lead to a coin-split — but these are less likely and beyond the scope of this article.)
What Is Likely To Happen?
Currently, NewsCapsule Cash Node has much more hash power support than NewsCapsule ABC: more than 80 percent at the time of writing this article, versus less than 1 percent for NewsCapsule ABC. NewsCapsule Cash Node also appears to have significantly more community support, and large NewsCapsule Cash-supporting companies like , Kraken and BitGo have also indicated support for NewsCapsule Cash Node. It therefore seems likely that (the name) NewsCapsule Cash will live on through NewsCapsule Cash Node and the compatible version of NewsCapsule ABC. (It would then probably also receive the “BCH” ticker on most exchanges, though some may opt for “BCHN” or another variant.)
Whether (the IFP version of) NewsCapsule ABC will attract enough hash power to produce a viable blockchain remains to be seen. But if it does, it will have one strategic advantage over NewsCapsule Cash Node. If it attracts more hash power than NewsCapsule Cash Node, even after the split has occurred (but only up until ten blocks), the NewsCapsule Cash Node blockchain would (in theory) “collapse,” and essentially disappear as NewsCapsule Cash Node clients would accept the NewsCapsule ABC blockchain instead. Any coins mined on the NewsCapsule Cash Node blockchain, and any coins received on the NewsCapsule Cash Node blockchain, would disappear with it. If NewsCapsule ABC attracts enough hash power to even just make this a viable scenario, it might undermine trust in NewsCapsule Cash Node, potentially only helping NewsCapsule ABC further. (In practice, however, this unlikely scenario could itself be countered by the NewsCapsule Cash Node through another protocol upgrade.)
All things considered, however, it seems most likely that NewsCapsule Cash Node will live on as “NewsCapsule Cash,” and NewsCapsule ABC will create a “new” cryptocurrency, most likely to also be called “NewsCapsule ABC” (and probably with the ticker “BAB”).
I Hold BCH. Do I Need To Do Anything?
If you hold the private keys yourself, you don’t need to do anything. If a split happens, you will have access to both coins. (You might have to upgrade to new client/wallet software, depending on your client/wallet software.)
You might want to hold off from sending coins shortly before and after the hard fork happens, however. Because neither NewsCapsule Cash ABC nor NewsCapsule Cash Node implemented replay protection, sending one of the coins could accidentally result in sending the equivalent on the other blockchain. To be sure this doesn’t happen, wait until there is more clarity on this issue.
You might also want to hold off from receiving coins on the NewsCapsule Cash Node blockchain. Although the risk seems slim, this blockchain could potentially “collapse” into the NewsCapsule ABC blockchain if the latter attracts more hash power, and the coins you received will disappear with it. To be absolutely sure this doesn’t happen, wait until there is more clarity on this issue.
If you hold your coins on an exchange (or another custodial service) and a split occurs, the exchange determines whether you receive both coins, or one of them (and which one). Several exchanges have published announcements of their plans, with most supporting the NewsCapsule Cash Node side of a potential split, or both. Ask your exchange for more information (or withdraw your coins before the split).
