Bitcoin Cash Upgrade Complete: 2 New Protocol Changes Added

The Bitcoin Cash network has successfully upgraded the latest ruleset changes to the protocol. The BCH blockchain now features the enforcement of minimal pushdata in script which will make a majority of BCH network transactions non-malleable. Moreover, as an extension to last May’s Schnorr upgrade, the opcode OP_Checkmultisig(verify) will now feature Schnorr signature support.

Bitcoin Cash Successfully Removes the Final BIP62 Malleability Vector and Extends Schnorr Signatures

Every six months the Bitcoin Cash (BCH) network upgrades in order to galvanize the BCH roadmap that aims to scale peer-to-peer electronic cash to the masses. BCH protocol developers strive to provide high-level technical direction with every completed upgrade. So far, software engineers have raised the block size to 32MB, re-enabled the Satoshi opcodes, implemented OP_Checkdatasig, added Canonical Transaction Ordering (CTOR), and the foundations of Schnorr signature support.

There are 20 platform and protocol developments completed according to statistics from Coin Dance. Scheduled upgrades on the BCH chain are meant to enhance scaling and overall reliability of the main network.

Bitcoin Cash Upgrade Complete: 2 New Protocol Changes Added

The latest additions to the BCH chain include a fix that will make most transactions on the BCH network non-malleable. The enforcement of minimal pushdata in script (Minimaldata rule) makes the malleability of transactions near impossible, including all P2PKH transactions. Years ago, several sources of malleability were known to developers and many of them were improved upon with the introduction of bip-0062. The Minimaldata rule change removes the final malleability vector after the upgrade on Friday. In addition to making the transactions on the BCH network non-malleable, Schnorr signature support will extend to OP_Checkmultisig(verify) which means all signature checking operations will support Schnorr signatures. The November 15 upgrade specifications state:

OP_Checkmultisig and OP_Checkmultisigverify will be upgraded to accept Schnorr signatures in a way that increases verification efficiency and is compatible with batch verification.

Bitcoin Cash Community Celebrates Another Successful Upgrade

After the upgrade, the BCH community celebrated the latest protocol changes. For instance, Collin Enstad hosted a live stream of the event and discussed the upgrade with software developer Mark B. Lundeberg. The upgrade went live on the BCH network at block height 609135, which was mined by the mining operation Antpool.

According to monitoring sites like Coin Dance and Fork Monitor, the upgrade went quite smoothly with no issues. Not too long after BCH block 609136 was processed by Btc.com after Antpool’s block, it ensured that all the new rules have been applied. “Bitcoin ABC 0.19.0 considers block height 609136 invalid,” the data website Fork Monitor explains. “This block was mined by BTC.com and it was first seen and accepted as valid by Bitcoin ABC 0.20.6.”

Bitcoin Cash developers have continuously pushed innovation and development to new heights and the November 2019 upgrade is no different. BCH fans will wait another six months for the next upgrade and news.Bitcoin.com will be there every step of the way to inform our readers about the next ruleset changes.

While Bitcoin’s price seemingly moves without rhyme or reason — collapsing by dozens of percent and embarking on face-melting rallies on a whim — the cryptocurrency market is filled to the brim with fractals.

A brief aside: A fractal, in the context of technical analysis and financial markets anyway, is when an asset’s price action is seen during a different time. This form of analysis isn’t that popular, but it has proven to be somewhat valuable in analyzing Bitcoin.

One recent fractal popularized by a well-known cryptocurrency trader is implying that BTC is going to return to the low-$7,000s in the coming days.

Bitcoin Fractal Implies Retracement to Low-$7,000s

A well-known crypto trader going by “Tyler Durden” on Twitter recently posted the chart below, which shows that a Bitcoin price fractal may be playing out. The fractal has four phases: horizontal consolidation marked by one fakeout, a surge above the consolidation phase, a distribution, then a strong drop to fresh lows.

If the fractal plays out in full, BTC could reach the low-$7,000s again, potentially as low as $7,100. This would represent a 20-odd percent collapse from the current price point of $8,800.

It isn’t only a fractal that is hinting Bitcoin has the potential to visit its lows. As we reported on Saturday, Bloomberg believes that if the GTI Vera Convergence Divergence Indicator flips red, a downtrend could push the cryptocurrency back to $7,300.

Can Bulls Step In?

But again, many believe it is irrational to have such bearish interpretations of the cryptocurrency’s chart at the moment. As reported by NewsBTC earlier, Popular crypto trader Mayne recently noted that the “people waiting for $6,000” are irrational. He quipped that Bitcoin retracing and consolidating after its fourth-biggest bull move in history ($7,300 to $10,500, a 42% gain) is perfectly par for the course, but noted that it’s totally possible we can go lower from $8,800.

The medium-term technicals support this.

Trader and CoinTelegraph contributor FilbFilb found that by the end of November or start of December, the 50-week and 100-week moving averages will see a “golden cross,” which he claims is far more significant” for the Bitcoin market that other technical crosses.

Also, a Bitcoin price model created using Facebook Prophet machine learning found that the leading cryptocurrency is likely to end the year at just over $12,000. What’s notable about this model is that it called the price drop to $8,000 months in advance, and forecasted a ~$7,500 price bottom for BTC.

To put a cherry on the cryptocurrency cake, Crypto Thies observed that when Bitcoin bottomed at $7,300, it bounced decisively off the 0.618 Fibonacci Retracement of the move from $3,000 to $14,000, which correlates with the two-week volume-weighted moving average. He added that summer 2019’s consolidation was marked by Bitcoin flipping major resistances into support levels, implying that a bullish reversal and subsequent continuation is likely possible in the coming weeks.
