SegWit2x (do not confuse with [[SegWit]]), also called B2X, was an attempt made by CEOs and owners of several Bitcoin businesses to introduce a change in Bitcoin with following goals:&lt;br /&gt;
&lt;br /&gt;
* increase block size limit to be 2 times bigger, despite block size being already increased by over 50% (for users of SegWit-enabled wallets) done just 3 months earlier by [[SegWit]] update.&lt;br /&gt;
* remove all other Bitcoin developers from their position&lt;br /&gt;
* instead install Jeff Garzik as the new de-facto developer (and possibly others)&lt;br /&gt;
&lt;br /&gt;
== Support rate ==&lt;br /&gt;
&lt;br /&gt;
It failed to gain consensus among community:&lt;br /&gt;
&lt;br /&gt;
* over 80% of miners by hashare (though they were just signaling, and this has no cryptographic or economical meaning or repercussions) &lt;br /&gt;
* just below 20% of users by economy ([https://www.bitfinex.com/order_book/bt2btc BitFinex futures market as BT2 token]) (representing actual trades that were executed for money)&lt;br /&gt;
* around 0% of Bitcoin developers (Bitcoin Core)&lt;br /&gt;
&lt;br /&gt;
== Attack or upgrade ==&lt;br /&gt;
&lt;br /&gt;
It was created in a way that would trick users into unknowingly switching to B2X from BTC, due to:&lt;br /&gt;
&lt;br /&gt;
* no replay protection&lt;br /&gt;
* simple SPV wallets without special tools to detect the problem would accept B2X blocks as BTC blocks&lt;br /&gt;
* same address formats&lt;br /&gt;
* code changes that allowed B2X nodes to pretend to be BTC nodes in order to connect and use P2P peers from BTC network&lt;br /&gt;
&lt;br /&gt;
due to this qualities, many users considered B2X and attack on BTC network.&lt;br /&gt;

It was created in a way that would trick users into unknowingly switching to B2X from BTC, due to:&lt;br /&gt;
&lt;br /&gt;
* no replay protection&lt;br /&gt;
* simple SPV wallets without special tools to detect the problem would accept B2X blocks as BTC blocks&lt;br /&gt;
* same address formats&lt;br /&gt;
* code changes that allowed B2X nodes to pretend to be BTC nodes in order to connect and use P2P peers from BTC network&lt;br /&gt;

due to this qualities, many users considered B2X and attack on BTC network.&lt;br /&gt;

&lt;br /&gt;
This resulted in the price of B2X futures (called &amp;quot;BT2&amp;quot; on BitFinex) to withing minutes drop down from around 12% to 8%, and in following hours to 1% of Bitcoin (BTC, called &amp;quot;BT1&amp;quot; as future).&lt;/div&gt;</summary>

SegWit2x (do not confuse with [[SegWit]]), also called B2X, was an attempt made by CEOs and owners of several Bitcoin businesses to introduce a change in Bitcoin with following goals:&lt;br /&gt;
&lt;br /&gt;
* increase block size limit to be 2 times bigger, despite block size being already increased by over 50% (for users of SegWit-enabled wallets) done just 3 months earlier by [[SegWit]] update.&lt;br /&gt;
* remove all other Bitcoin developers from their position&lt;br /&gt;
* instead install Jeff Garzik as the new de-facto developer (and possibly others)&lt;br /&gt;
