The two pieces of software, Bitcoin Core and Bitcoin-XT, are very similar. Bitcoin-XT is actually just a fork of Bitcoin Core with some features added that Bitcoin Core developers didn't deem appropriate, such as a larger block size (BIP 101) and relaying of double spends. Bitcoin Core is more up-to-date with all of the work that the community doing. ...

BIP 100: Jeff Garzik Miners vote on blocksize, constrained between 1 and 32 MB. BIP 101: Gavin Andresen Blocksize increases to 8 MB, and doubles every two years after that. (This is what XT implements.) BIP 102: Jeff Garzik Blocksize increase to 2 MB. (Intended as a fallback that everyone can agree on.) BIP 103: Pieter Wuille Blocksize increase by 17.7% each ...

The two clients are based off of the same code base. To use Bitcoin-XT, you only need to make sure your Bitcoin Core client is shut off when you start the Bitcoin-XT client. The two programs use the same data directory and wallets, so all your coins will still be there. See "Should I be running Bitcoin Core or Bitcoin-XT?" for more info regarding the ...

Ultimately I believe the chain with most work should be the valid one, suppressing all other chains. In fact if you use an SPV client, such as MultiBit, you don't even check the size of the block, because you only use the headers. So if that's the rule, your money will only ever be in one chain: the one where most computing power was used to generate it. ...

Bitcoin has not been forked yet. Once XT nodes mine 75% of all bitcoin blocks, XT will support a larger block size that will be incompatible with current bitcoin client. At that time, the blockchain is forked and the bitcoin currency would be divided into two, Bitcoin and BitcoinXT. what is the impact on the current existing Bitcoin holders? A ...

Bitcoin XT versions 0.11A through 0.11D supported the withdrawn BIP101, which set version = 0x20000007 as a best-guess nod toward the developing versionbits standard, while trying to maximize backward compatibility with the ways nodes might check for compatible versions. Bitcoin XT version 0.11E supports BIP109, identical to Bitcoin Classic.

This is clearly a scam and not a very good one at that. The website design and English grammar on the website is appalling. It looks like it was outsourced via upwork.com with a $10 budget. At least they are honest about the quality of the English grammar on the website as seen by the Html lang="zxx" tag in the page source; which basically translates as 'the ...

sites like this are always scam. you can double your assets when you exchange your bitcoins in (mostly unknown) altcoins which have increasing charts in the next 24h. but no one can warranty that this works in your case. it can work: look at this or this or this or this chart. and there are several more charts likes these where the value of 1 coin increases ...

The miner does not need a software upgrade to mine with Bitcoin XT. The pool or whichever mining solution you choose would need to connect to a Bitcoin XT node rather than a Bitcoin core node.

How Unlikely is it to pull of an attack to a website that credit users on 6 confirmations? I would say extremely unlikely as discussed here, here, here and here. Unless you are selling small islands on the website there would be no incentive to acquire the immense resources required for an attack.

How can merchant be alerted of any double-spend attacks ? Running their own daemon will achieve that. Procedures to consider in the time of the attack ? e.g Shutting down servers to avoid confusion and recheck balances to avoid dead ends on user withdrawals Any backend services run by a merchant need to be able to handle block chain reorganisations ...

Compact Blocks in Bitcoin Core provides similar functionality (see BIP 152 for spec). The main improvement is in the way it gets rid of bloom filters, as those add a DoS attack risk. There's a bit more in commentary from nullc (Gregory Maxwell) in this thread on Reddit
