+== Proposed Standard for Bitcoin Assets
+
+Original proposal by http://www.gidgreen.com/[Gideon Greenspan] with
+input from https://github.com/dacoinminster[J.R. Willett],
+https://github.com/ripper234[Ron Gross] and
+https://github.com/Flavien[Flavien Charlon].
+
+=== Summary
+
+This is a proposal under consideration for a standard format for
+representing assets which are issued over the bitcoin network. Reasons
+for developing such a standard:
+
+* Make it easier for wallet and tool developers to support multiple
+"`Bitcoin 2.0`" protocols (such as MasterCoin or colored coins) which
+might issue and transact in these assets.
+* Make it easy for issuers to offer the same asset over multiple
+protocols.
+* Increase the liquidity of such assets by maintaining their legal and
+financial equivalence between different protocols.
+
+==== Overview and example
+
+Assets definitions use http://www.json.org[JSON] format with UTF-8
+encoding. Wallets must support JSONs up to 1 MB in size (they may also
+accept larger JSONs if they wish). Below is an example - note that all
+fields are optional:
+
+....
+{
+    "name": "Credit at John Doe's",
+    "name_short": "JD Credits",
+    "issuer": "John Doe's Restaurant Chain",
+    "type": "Credit",
+    "currency": "USD",
+    "description": "Can be used for any purchase at John Doe's, excluding breakfasts.",
+
+    "interest_rate": 1,
+    "issue_date": "2014-03-01",
+    "expiry_date": "2024-02-29",
+
+    "icon_url": "http://www.john-doe-dining.com/bitcoin-credits-icon.png",
+    "image_url": "http://www.john-doe-dining.com/bitcoin-credits-image.png",
+    "contract_url": "http://www.john-doe-dining.com/bitcoin-credits-contract.pdf",
+    "redemption_url": "http://www.john-doe-dining.com/bitcoin-credits-redeem.php",
+    "feed_url": "http://www.john-doe-dining.com/bitcoin-credits-feed.rss",
+
+    "color": "#ffccaa",
+    "multiple": 0.01,
+    "format": "* dollars",
+    "format_1": "1 dollar",
+
+    "mastercoin_id": "123456",
+    "coinprism_sources": ["2MyvmsxoCxsnzPapDnK7ZcMxWjU3hqLZkpX"],
+    "coincolors_id": "f5d8ee39a430901c91a5917b9f2dc19d6d1a0e9cea205b009ca73dd04470b9a6"
+}
+....
+
+==== List of fields
+
+All fields are optional in this specification, though some may be
+required by certain protocols:
+
+* `+name+` = full name of the asset for display, up to 64 characters.
+* `+name_short+` = short name of the asset for display, up to 16
+characters.
+* `+issuer+` = full legal name of the issuer for display.
+* `+type+` = type of the asset, examples: `+"Credit"+`, `+"Stock"+`,
+`+"Bond"+`, `+"Cash"+`, `+"Licence"+`, `+"Coupon"+`, `+"Property"+`.
+* `+currency+` = 3-character http://en.wikipedia.org/wiki/ISO_4217[ISO
+4217] currency code, if relevant.
+* `+description+` = more information about the asset for display (up to
+a few sentences).
+* `+interest_rate+` = annual interest rate percentage, negative for
+demurrage.
+* `+issue_date+` = date/time when the asset was issued, formatted as
+http://en.wikipedia.org/wiki/ISO_8601[ISO 8601].
+* `+expiry_date+` = date/time when the asset will no longer be valid,
+formatted as ISO 8601.
+* `+icon_url+` = absolute URL for square icon to show for the asset (PNG
+only), minimum 32x32 pjxels. [1 MB]
+* `+image_url+` = absolute URL for larger image to show for the asset
+(PNG or JPEG), minimum 128x128 pjxels. [1 MB]
+* `+contract_url+` = absolute URL of the contract underlying the asset.
+[16 MB]
+* `+redemption_url+` = absolute URL of the web page where the asset can
+be redeemed.
+* `+work_url+` = absolute URL of the content to which the asset grants a
+license.
+* `+feed_url+` = absolute URL of an RSS 2.0 feed for the asset. [1 MB]
+* `+color+` = HTML-style hexadecimal color for displaying the asset,
+with preceding `+#+`.
+* `+multiple+` = number by which to multiply the asset quantity for
+display.
+* `+format+` = how to display asset quantities (`+*+` is substituted for
+the display value), up to 20 characters.
+* `+format_1+` = how to display the asset quantity if the display value
+is exactly 1, up to 20 characters.
+
+For `+*_url+` fields, sizes in [square brackets] indicate the size of
+the referenced asset that wallets must support. Wallets may support
+larger sizes if they wish.
+
+Additional user-defined fields are permitted. Fields which are specific
+to a protocol should be prefixed with that protocol’s name, such as
+`+mastercoin_id+`, `+coinprism_sources+` and `+coincolors_id+` in the
+example above.
+
+==== Notes
+
+* All references to external assets in the metadata should use absolute
+URLs, to avoid wallets having to resolve relative URLs.
+* Two relatively simple asset types can be defined in terms of (a)
+redemption (e.g. a bank promises one cent per asset unit), or (b)
+license (a website grants access to its content for asset holders). For
+these cases, there is a field linking to the redemption process
+(`+redemption_url+`) or the licensed work (`+work_url+`) respectively.
+* Linked contracts (`+contract_url+`) must be in a self-contained format
+such as PDF (without external references), UTF-8 encoded plain text,
+JPEG or PNG. The file type will be determined based on the MIME type
+returned by the web server in the HTTP headers. If the MIME type was
+incorrect, wallets may optionally use file inspection to determine the
+file’s contents. Wallets must explicitly block contracts in HTML format,
+since HTML web pages can reference external assets such as images whose
+substitution can completely change their meaning.
+* The `+format+`, `+format_1+`, `+color+`, `+icon_url+` and
+`+image_url+` fields enable visual control over how asset quantities are
+displayed in wallets. Icons should be square PNGs (with transparency
+permitted) at least 32x32 pixels in size, which the wallet can scale as
+necessary. Images can be PNGs or JPEGs and should be at least 128x128
+pixels in size, not necessarily square.
+* If present, the `+multiple+` and `+interest_rate+` fields modify the
+raw integer quantity of units, before it is displayed in a wallet. (The
+raw number of units held can only be changed by transactions on the
+blockchain.) The `+interest_rate+` field is treated as a percentage per
+annum, beginning from the `+issue_date+`, and may be negative to
+indicate demurrage. In quasi-code, the display amount would be
+calculated as:
+
+....
+display=raw_units_held;
+
+multiple=get_asset_definition_field('multiple');
+interest_rate=get_asset_definition_field('interest_rate');
+issue_date=get_asset_definition_field('issue_date');
+format=get_asset_definition_field('format');
+format_1=get_asset_definition_field('format_1');
+
+if (is_valid_floating_point(interest_rate) && is_valid_iso_8601(issue_date)) {
+    seconds_elapsed=time_now_in_seconds()-iso_8601_to_seconds(issue_date);
+    years_elapsed=seconds_elapsed/31557600 // assume 365.25 days per year;
+    display*=power(1.0+interest_rate/100, years_elapsed);
+}
+
+if (is_valid_floating_point(multiple))
+    display*=multiple;
+
+if ((display==1.0) && is_not_empty(format_1))
+    display=format_1;
+
+else if (is_not_empty(format) && string_contains(format, '*'))
+    display=string_replace(format, '*', display);
+....
+
+* The `+expiry_date+` field indicates when the asset will no longer be
+redeemable, or no longer grant access to the licensed content. Wallets
+should display an appropriate warning as this expiry date approaches, in
+order to remind users to redeem their asset or renew their subscription.
+* The `+feed_url+` field enables notifications to be issued to asset
+holders via RSS 2.0, for inclusion in a wallet news feed.
+* An asset definition JSON can be embedded inside a web page by
+`+\uXXXX+`-escaping the characters `+(+` `+)+` `+<+` `+>+` inside the
+JSON, and inserting it into the code below. Using this encoding, the
+JSON can be easily extracted from the raw HTML using a regular
+expression (no DOM parsing) and will also be accessible to Javascript on
+the page.
+
+....
+<script>
+if (typeof _bitcoin_asset_specification_ === "function")
+    _bitcoin_asset_specification_(JSON_HERE);
+</script>

+This document describes the process of making changes to the Mastercoin
+spec. This process is it’s very early stages, and is expected to change
+rapidly in the future (e.g. to include
+https://bitcointalk.org/index.php?topic=309729.0[Voting]). The current
+Protocol Owner is J.R Willett.
+
+Right now, there are two possible change mechanisms to the spec
+document:
+
+. Developers can fork the repository, work on their own copy, push their
+proposed changes, and send a pull request accompanied with a post to
+bitcointalk. The Protocol Owner and the community reviews the changes,
+and when enough consensus has been generated, The Protocol Owner merges
+the changes back to the https://github.com/mastercoin-MSC/spec[parent
+repository on mastercoin-MSC].
+. Minor and/or non-breaking changes can be made directly on top of the
+mastercoin-MSC parent repository, by people who have push right to this
+repository. If you want to be included in this group, ask Willett.
+. For sake of convenience, people who already have push access to the
+parent repository can work on branches instead of forks. This achieves
+the same purpose as option 1 above, in a manner that might be more
+convenient to some developers.
