Abstract This SIP defines a new "Ident" extended transaction.

The ident extended transaction is used in order to certify the originating sender of funds or other auxilliary information.

---

Motivation The ident extended transaction is intended to provide a method for third-party application to verify the originating identify of funds being sent.

In addition, the transaction may be used in order to "stamp" auxiliary information onto the block-chain. This can include general information or something more specialized like a geodetic address.

---

Specifications The Certification of a transaction is performed by creating chains of extended transactions which utilize an "Ident" structure or a "Certificate" structure (see below).

Several other extended transactions utilize the "Ident" or "Certificate" extended transaction structure as a base.

---

Structure The "Ident" extended structure consists of the following;

{

	/* A geodetic location. */

	shgeo_t geo;

	/* A coin address key. */

	cbuff vAddr;

	/* A mode indicator. */

	unsigned int nType;

}

---

Usage A "Certified Funds Transfer" is comprised of a regular fund send transaction with the addition of a "Ident" extended transaction.

The ident extended transaction optionally tracks the geodetic location of the originating node server, and a payload of textual information up to 135 characters.

An ident transaction can specify a geodetic location by using the format "geo:latitude,longitude" where latitude and longitude are in decimal degrees format.

See SIP21 for additional usage of ident extended transactions utilizing geodetic locations.
