With Bitcoin developers having mentioned possible development (yeah right lol) of "Confidential Transactions" they see that privacy AND moreso fungibility of bitcoin is a huge issue moving forward.
Yes, i think they slowly start to realize that lack of privacy and fungibility is a problem.
But what would happen with monero, if bitcoin actually managed to introduced these features. If this would happen, that there would be no point in monero? Could monero survive, if bitcoin incorporated zerocash or whatever technique to ensure privacy and fungibility of transactions?
1. If bitcoin implements features that match monero's then monero would probably be irrelevant.
2. But I doubt they will implement anything on a substantial level of development (or change) to the code base.
3. Zero cash doesn't exist yet right?
Given the lack of agreement about blocksize, stealth addresses, coinjoin and a slew of other features it seems rather unlikely that BTC would achieve parity with Monero anytime in the near future.
Zero cash is still in the whitepaper phase. Its fundamentals involve some undesirable, possibly intrinsic/unavoidable trade-offs and compromises (ie, a trusted third party and bloat-prone tx|blockchains).
The BIP process is healthier than ever before. It has been reinvigorated thanks to stimulus provided by the Fork of July, and perhaps even XT's lulzy failed governance coup. Please stop Buttcoining just because you Gavinistas didn't get your way, despite copious amounts of hand-wringing melodrama.
The results of #ScalingBitcoin will be eventual agreements about (if not blocksize) stealth addresses, coinjoin, and a slew of other features (ie sidechains|CT). Those non-controversial new featues cannot be directly compared to the universal contention necessarily involved in hard forks which risk catastrophic consensus failure occurring at the exact moment the socioeconomic ecosystem bifurcates into civil war.
Confidential Transactions on sidechains represent a medium-term possibility of a (possibly near-perfect or superior) substitute good for Monero. Let's not dismiss ridicule notion because it doesn't suit the Monero 4evar narrative, or dismiss the challenge because of butthurt at Blockstream/Theymos/p2pool/etc.
Competition is a good stream for us end-users. The possibilities of leisurely cross pollination in peacetime and horizontal gene transfer in emergencies strengthen both systems.
As for the narrow speculative POV, XMR's sort-of-first mover advantage may be neutralized by transfer of Bitcoin's undisputably-first mover status to its sidechains.
But sidechains and CT are unproven so a significant period of time, to accumulate Lindy effects appropriate to wealth storage, is required.
Then there is the possibility of adapting SC/LN for XMR, so our favorite mustang can become the opaque Father to complement Bitcoin's transparent Mother of All Settlement Chains.
That will take some new crypto, or at the least a novel arrangement of existing primitives. We can't do it yet, but may not have to endure such heavy lifting alone. The Cryptonote people are still Out There Somewhere and if anyone knows how to scale 100% trust-free 100% anon blockchains, it's probably Nick Szaborhagen's group.
