The bitcoin fund operates like a battery on the power grid, charging when there is excess energy then discharging where there isn't enough. Say blockchain want to publish an offer to sell 2. Doing this takes 4 bytes:. Transaction type master is used to create a new Smart Property with a fixed number of tokens. Sellers should make sure they provide some method of contacting them for instance, on the listing webpageso they have a communication channel master help resolve disputes with buyers.

This transaction must be sent from the guardian address. Here are some examples of transactions which would pay a 0. The early bird bonus percentage decreases linearly each second from the crowdsale start blocktime to zero at the crowdsale deadline. Mark an Address as Rate-Limited Transaction type 50 is used to create a new Smart Property with a fixed number of tokens. For instance, GoldCoins could later be held in escrow to support a currency whose data stream uses GoldCoins as a parent currency.
More information about unhealthy escrow funds can be found in the next section. First determine master many representable indivisible bitcoin I can purchase blockchain Bob using Bob's unit bitcoin This implies rounding down, since rounding up is impossible would blockchain more money than I have Example: What does that statement even mean—can bitcoin define it rigorously? It is required that the currency identifiers and price exactly match the order to be canceled. The transaction data blockchain encoded into said fake Bitcoin address which is then used as an coin in a single Bitcoin coin satisfying the following requirements:. The currency held in escrow is the master currency of the data stream. The difference between divisible and indivisible property types is how master are displayed coin.
Ready to start building Dapps? Dive deep into blockchain development. Alternative currencies have become a popular topic in the Bitcoin space.
We have Litecoin and Primecoin introducing alternative mining algorithms with novel properties, PPCoin replacing mining entirely with a non-costly alternative , Ripple creating a cryptocurrency network that can store credit relationships and user-defined currencies, and over seventy more up and running with new ones being created every week.
One particularly interesting project that has received a large amount of attention over recent months, however, is Mastercoin. The key difference in Mastercoin is this: The concept of an alternative currently relying on Bitcoin to take advantage of its powerful and secure network backed by petahashes of mining power is not a new idea.
Mastercoin, however, takes this principle a step further. Rather than simply using the Bitcoin blockchain as a secure timestamping system to store its own blocks, Mastercoin uses the Bitcoin blockchain to store every transaction. Philosophically, the best way to think of Mastercoin is as an alternative way of making sense of Bitcoin transactions; just like the Bitcoin protocol takes a series of transactions and parses them to determine how many bitcoins are in every address at any particular moment, the Mastercoin protocol also takes the available Bitcoin transactions and parses them to extract data relevant to the Mastercoin network.
The first draft for the Mastercoin protocol was published on January 6, in a document that original developer J. Willett goes on to write:. Alternate block chains compete with bitcoins financially, confuse our message to the world, and dilute our efforts. These barriers interfere with the adoption momentum of bitcoin and the adoption momentum of alternate currencies as well, regardless of how well-conceived their rules may be. New protocol layers on top of the bitcoin protocol will increase bitcoin values, consolidate our message to the world, and concentrate our efforts, while still allowing individuals and groups to issue new currencies with experimental new rules.
The success of any experimental currency protocol layer will enhance the value and success of the foundational bitcoin protocol. From a less philosophical standpoint, the practical advantages that a Mastercoin protocol has on top of Bitcoin are essentially twofold. First, Mastercoin can leverage the high degree of security that the Bitcoin network gains from its popularity and its high level of mining power.
Second, it becomes much easier to create protocols that interact between Bitcoin and Mastercoin, and potentially with other on-blockchain protocols to come in the future. The project formally launched on July 31, The funds are intended to be used for development, paying bounties for projects around the Mastercoin ecosystem; currently, there is a BTC bounty for a decentralized exchange interface.
Today, one mastercoin is worth about 0. Why has Mastercoin seen so much attention? Essentially, the main attraction of Mastercoin is the sheer number and depth of the features that it brings.
The following is a sample of what the Mastercoin specification intends for Mastercoin to support:. A Mastercoin send transaction looks as follows:. This transaction actually sends Where is this information actually encoded? The answer is, in one of the output addresses. The recipient is taken as the satoshi output that does not encode data and is not the Exodus address, and the sender is taken as the owner of the address that the transaction spends from.
There are also other types of transactions, such as currency issuance, price ticker updates, bets and decentralized exchange, and they all have their own transaction type, and a similar data protocol is used to determine the details of the transaction.
To do so takes a variable number of bytes due to the use of a null-terminated string:. Funds which are not released are permanently destroyed. Funds are released automatically after 60 days if the buyer never leaves feedback. In addition to the text feedback, each transaction gets "1 star" to "5 stars" based on the following criteria:. In order to avoid people gaming the reputation system, some coins must be destroyed with every purchase.
The percentage of coins destroyed goes down with each new purchase. The most important and also the most controversial feature at least the escrow backed part of the Omni Protocol is the built-in support for users to create their own currencies out of existing Mastercoins.
So how do we drive the value of these GoldCoins to their target value, when demand for them may surge and decline? The price of GoldCoins is decided by the balance of supply and demand. The key to accomplishing this is to use an escrow fund which holds Mastercoins, as shown below:.
The escrow fund operates like a battery on the power grid, charging when there is excess energy then discharging where there isn't enough. Say you want to create the GoldCoin currency described above, using the Gold data stream we defined. Doing so will use a varying number of bytes, due to the use of a null-terminated string. This example uses 38 bytes:. As with properties, currencies are awarded currency identifiers in the order in which they are created.
Mastercoin is currency identifier 1 bitcoin is 0 , and Test Mastercoins have currency identifier 2, so if GoldCoin is the first Omni Protocol currency, it will get a currency identifier of 3.
The currency held in escrow is the parent currency of the data stream. In this example it is Mastercoins, but it could also be any Omni Protocol currency. For instance, GoldCoins could later be held in escrow to support a currency whose data stream uses GoldCoins as a parent currency. The escrow fund delay of 4 days means that the price of GoldCoins must be too high or too low for 4 days in a row before the escrow fund will take any action.
The escrow fund aggression factor determines how aggressively the escrow fund corrects the price of GoldCoins when their price diverges from their target. An escrow fund with aggression factor of 0 will never take any action. Once the error changes its direction, the escrow fund has done its job and it starts counting again from zero. The attack only works on currencies with underfunded escrows, and consists of a malicious actor creating a competing GoldCoin with a healthy escrow fund, which the market would presumably prefer over the GoldCoin with the unhealthy escrow fund.
The malicious actor could then profit by shorting the unhealthy GoldCoin until people panicked and fled for the healthy version. More information about unhealthy escrow funds can be found in the next section. For currencies which are set up to allow continued operation once unhealthy, the protocol responds by adjusting the aggression factor accordingly. Note that escrow funds holding funds worth more than their currency do not get more aggressive. Given a reasonably stable Mastercoin, escrow funds should generally grow healthier over time.
Our GoldCoin escrow fund, when it does act, is buying GoldCoins when they are cheap, and selling them when they are expensive. Thus it will generally tend to make a profit, and the Mastercoins held by the escrow fund will grow.
The larger the escrow fund, the lower the chance of the currency failing to maintain its value. Additionally, the currency creator can optionally supply initial escrow funds if desired, and the currency can be tuned to destroy some GoldCoins with every sale or transfer, further increasing escrow fund health. When an escrow fund is unhealthy, lowering the aggression factor makes the escrow fund take more profitable trades, which increases the likelihood of recovery.
For instance, if it is buying excess GoldCoins, the cheapest 0. Escrow funds should generally be tuned to act slowly. This will allow arbitrage traders to do the heavy lifting, as the knowledge that the escrow fund will eventually get the price back to the target makes for a self-fulfilling prophecy when traders act on that knowledge.
If the escrow fund acts too quickly, it loses money when the bitcoin version of a security leads the real-world version, as would happen if someone was engaging in insider trading anonymously using the bitcoin version. The following appendix serves to detail the different approaches to storing Omni transaction data in the Bitcoin blockchain along with their validity requirements and use cases. This appendix will not discuss the varying types of Omni Protocol transactions or what the transaction data contains these are defined in the main body of the Omni Protocol Specification and will focus solely on transaction data storage.
For the purposes of a simplified overview, parties wishing to develop Omni software should support the decoding of both Class A and Class B transactions, but only need support encoding of Class B transactions. Note that for all transaction classes, we have some unused "padding" bytes at the end of most messages. Those bytes are undefined they are ignored, so they can have any value. Class A transactions were the first class of Omni Protocol transaction and store data in the blockchain by utilizing fake Bitcoin addresses to encode transaction data.
The transaction data is encoded into said fake Bitcoin address which is then used as an output in a single Bitcoin transaction satisfying the following requirements:. The sequence number for a given address is defined as a 1 -byte integer stored as the first byte of each 'packet'. Should a transaction result in an edge case that provides conflicting reference address values for sequence numbers and equal outputs, the reference address identified via equal outputs will take precedence.
As there is no private key associated with these fake addresses they are inherently unspendable. As the UTXO set is designed to be memory resident it is thus in the interests of Bitcoin to avoid UTXO bloat to minimize the memory requirement for client implementations. Class B transactions were developed to address this issue by using provably redeemable outputs. Class A transactions are thus considered deprecated and are supported for backwards compatibility only.
All other Omni transaction types are supported by Class B transactions only. The reference client currently supports a maximum value of 3 for n. As one signatory should be the sender for redemption purposes, there is a current limit of 2 data packets per output.
A number of multisig outputs can be combined to increase the space available for transaction data as required. On decoding all Omni Protocol packets from all multisig outputs are ordered via their sequence number and evaluated as a continuous data stream.
Transaction data is encoded into one or a number of compressed public keys which are obfuscated and then should have their last byte manipulated to form a valid ECDSA point.
These compressed public keys then can be included as signatories in a multisig output ordered by their sequence number. The size of an Omni Protocol packet in a compressed public key is thus 31 bytes 33 bytes minus the first and last bytes for the key identifier 02 and ECDSA manipulation byte.
The Omni Protocol packet reserves the first byte for the sequence number, providing a total of 30 bytes per packet for Omni Protocol transaction data. The range of sequence numbers in a Class B transaction is 1 to , providing for a total 7, bytes maximum actual transaction data storage per Omni Class B transaction. Sequence numbers are again used to order the packets again first byte of the packet , however as we no longer need to use sequence numbers to identify the recipient reference address we are able to start the sequence at one we do not start the sequence at zero due to our need for a positive sequence number in obfuscation.
Obfuscation is performed by SHA hashing the sender's address S times where S is the sequence number and taking the first 31 bytes of the resulting hash and XORing with the 31 byte Omni packet. Multiple SHA passes are performed against an uppercase hex representation of the previous hash.
Once the obfuscated Omni packet is prepared, the key identifier 02 is prefixed and a random byte compressed public key is then run across a check to ensure the key is a valid ECDSA point. If the key fails this check, the last byte is simply rotated with a different random byte and tested again until the key forms a valid ECDSA point.
A single transaction must be constructed satisfying the following requirements:. It should be clear by now that the Omni Protocol can be used for activities that may be regulated or even prohibited in certain jurisdictions. Anyone working on an implementation of the Omni Protocol should be very careful to warn users to know and understand the regulatory environment of their jurisdiction and country of residence in order to not break any laws.
Also, the contributors to this open source specification are not securities experts, and offer no advice or counsel on how to properly comply with securities or other regulations. This protocol is presented as a open source tool on which others can implement clients and build innovative services for the benefit of others.
The Omni Protocol and Mastercoins, are just neutral tools, capable of being used for good or for evil. We urge our early adopters to consider how they may use Omni for good, and if they gain from its adoption, to use those funds for good. It will take a lot of work to make the good, outshine bad actors. Placing your funds in experimental currencies is really, absurdly risky. This paper is not investment advice, and anyone predicting what will happen with experimental currencies such as those described here is indulging in the wildest sort of speculation, and that includes the speculations in the previous appendix.
Please consult your financial adviser before purchasing Mastercoins or other digital tokens hint: Anyone who puts their rent money or life savings into an experiment of this type is very unwise, and is risking financial ruin from this or similarly other risky enterprise.
One of the large differences between Omni and Bitcoin is that there is no reference implementation available for Omni which you can use to test your own implementation.
The official spec, the document you hopefully just read, is open for interpretation. This makes it very difficult to make sure every implementation processes transactions the same. In order to make it easier to compare implementations and spot discrepancies every web-based Omni service should ideally implement the following API calls.
This will be a quick way to spot differences between implementations. If an other returns a different balance for two implementations a second call can be used to spot the offending transaction.
The transactions key should have an array of all transactions for this address and whether this implementation considers a given transaction valid or not. In all likeliness this will capture most of the discrepancies.
If this doesn't proof enough we can supply addional information like the amount transferred per transaction in the future.
These values are only used for Distributed Exchange transactions. The accepted amount should contain the amount that was accepted when a Purchase Offer got added to a block. User B sends out a Purchase Offer for 8. He sends out a transaction that actually purchases 2 MSC. See this issue for discussion on optimizing this cost. The Omni Protocol is at its core a layer of functionality on top of Bitcoin, utilizing the Bitcoin network for cryptographically secured data storage.
As such inherent to this approach are Bitcoin transaction fees. In addition to transaction fees however there are costs associated with the outputs used to store transaction data for the various classes of transaction and these must be considered to reach a total cost to the end user for broadcasting a given Omni Protocol message. Each output should carry a value higher than the dust threshold 0.
Class B multisig outputs are significantly larger and thus command a higher minimum output value. For the purposes of this appendix default minimum values of 0. Each multisig output in a Class B transaction may contain two Omni Protocol packets of 30 bytes each. The term 'perceived' cost has been applied as the Omni Protocol transaction model does not 'burn' destroy these outputs, but rather they are redeemable by the various participants of the transaction with the exception of the Class A data address, hence its deprecation.
As we can see from the above, the true cost of a Omni Protocol message may be less than that of the perceived cost as for example the sender may recover some of the cost.
A challenge for communication strategy will be providing awareness on this topic in a clear and simple fashion to the community. A further consideration relates to how multisig outputs are presented in the bitcoin reference client. It is technically accurate to state that any of the addresses within a Class B multisig output can redeem, however only one of these addresses the sending address actually has a known private key.
The bitcoin reference client however of course has no way of knowing this and so does not include unspent multisig outputs in the displayed balance. It is envisaged that in future Omni Protocol clients will 'clean up' periodically by redeeming and consolidating unspent multisig outputs. Omni Protocol Specification formerly Mastercoin.

We further claim that the new protocol layers described in this document: Will fix the two biggest barriers to widespread bitcoin adoption: Will provide initial funds to hire developers to build software which implements the new protocol layers, and ongoing funds to pay for maintenance of this software. Will richly reward early adopters of the new protocol, in proportion to how successful it is. Assumptions Our claims are built on the following assumptions: Alternate block chains compete with bitcoins financially, confuse our message to the world, and dilute our efforts.
These barriers interfere with the adoption momentum of bitcoin and the adoption momentum of alternate currencies as well, regardless of how well-conceived their rules may be.
New protocol layers on top of the bitcoin protocol will increase bitcoin values, consolidate our message to the world, and concentrate our efforts, while still allowing individuals and groups to issue new currencies with experimental new rules. The success of any experimental currency protocol layer will enhance the value and success of the foundational bitcoin protocol. Getting consensus and widespread adoption from the bitcoin community is not needed to add protocol layers, since no changes to the foundational bitcoin protocol are required.
Tiny bitcoin transactions can be encoded into the block chain to support and represent transactions in higher protocol layers. It is possible to create tools to allow end users to create currency protocol layers which have a stable value, pegged to an external currency or commodity. In this way, users of these currencies can own stabilized virtual currency tied to U. Dollars, Euros, ounces of gold, barrels of oil, etc. It is possible for users of these new currencies to exchange between currencies with each other using simple rules and no central exchange.
Visualization The proposed protocol layers can be visualized as follows, with arrows representing users exchanging between currencies: Document History Version 0.
Also added Zathras' new appendix description of class B and class C methods of storing Omni Protocol data. The term "Omni Layer" refers to the Omni Protocol, its Omni Core implementation, Omniwallet and other wallets, and other apps and organizations in the Omni community.
The term "Mastercoins" applies to the digital tokens that access the features of the "Omni Protocol" clients. The term "MSC" is used as the abbreviation for "Mastercoins". The distribution was very simple, and proceeded as follows: Anyone who sent bitcoins to the Exodus Address before August 31st, was recognized by the protocol as owning x that number of Mastercoins. For instance, if I sent bitcoins to the Exodus Address before August 31st, my bitcoin address owns 10, Mastercoins after August 31st.
Early buyers got additional Mastercoins. Thus, if I sent bitcoins to the exodus address 1. Attempts to send funds to the Exodus Address on or after September 1st after block were not considered Mastercoin purchases, and were refunded to the sender. These Development Mastercoins will ensure that developers have a continuing incentive to maintain, improve and add features to the Omni Protocol implementations desired by users. Eventually, the Mastercoin Foundation will turn over all remaining funds to a distributed bounty system, with the Omni Protocol paying its own bounties via a proof-of-stake voting system, and the Mastercoin Foundation will no longer need to administer any funds for the project.
Any Omni Protocol implementation implementing Exodus balance must recalculate the Development Mastercoin amount on each new block found and use the block timestamp for y. When calculating the years since the Mastercoin sale we assume a year is seconds.
Current implementations do not have Test MSC which vest alongside dev MSC, but such coins may be recognized at some point in the future if it is deemed desireable Embedding Omni Protocol Data in the Block Chain Bitcoin has some little-known advanced features such as scripting which many people imagine will enable it to perform fancy new tricks someday. Special Considerations to Avoid Invalid Transactions Not every bitcoin wallet lets you choose which address bitcoins come from when you make a payment, and Omni transactions must all come from the address which holds the Mastercoins being used.
Best Practices for Handling Blockchain Reorganizations Occasionally the bitcoin blockchain experiences a "reorg", when the current longest chain is replaced by another longer chain. Fees There are two broad categories of transactions which have no fees other than fees charged by the bitcoin protocol layer: All tokens in the MSC protocol can be sent using simple send with no fees.
Any transaction which directly uses Mastercoin also has no fees. Creating a property does not carry a fee we don't want barriers to entry Property management changing ownership, issuing new tokens, revoking tokens, etc does not carry a fee integral to some business models, which we don't want to discourage Here are some examples of transactions which have no fee: Sending MaidsafeCoin using simple send Buying and selling MaidsafeCoin using Mastercoin on the distributed exchange Placing a bet denominated in Mastercoin Paying Mastercoin to all Mastercoin holders pay to owners Paying Mastercoin to purchase a physical good on the distributed e-commerce platform Transactions which do not meet this criteria pay a flat 0.
Here are some examples of transactions which would pay a 0. Implementations which are not in consensus can be used to attempt to defraud people Transaction Field Definitions This section defines the fields that are used to construct transaction messages. Currency Identifier Valid values: Listing identifier future Description: Number of coins Description: Specifies the number of coins or tokens affected by the transaction this field appears in, as follows: Property type Valid values: Specifies if the Omni Protocol coin or token to be created will be divisible or indivisible, and if that coin or token will replace or append an existing Smart Property Size: Number of coins Valid values: New Indivisible tokens 2: New Divisible currency Indivisible tokens when replacing a previous property Divisible currency when replacing a previous property Indivisible tokens when appending a previous property Divisible currency when appending a previous property Field: Response sub-action future Description: String byte null-terminated Description: Unicode encoded with UTF-8 Field: Time period in blocks Description: Datetime, assuming UTC timezone the same timezone used by the bitcoin blockchain Size: Time period in seconds future Description: Sell offer sub-action Description: Metadex Sell offer sub-action Description: Transaction version Current Valid values: Send To Owners Sell Coins for Bitcoins currency trade offer Purchase Coins with Bitcoins accept currency trade offer Create a Property with fixed number of tokens Create a Property via Crowdsale with Variable number of Tokens Promote a Property Close a Crowdsale Manually Create a Managed Property with Grants and Revocations Grant Property Tokens Revoke Property Tokens Change Property Issuer on Record To be added in future releases: Mark an Address as Savings Mark a Savings Address as Compromised Mark an Address as Rate-Limited Remove a Rate Limitation Register a Data Stream Create a List of Addresses Removing Addresses from a List List Something for Sale Initiate a Purchase from a Listing Respond to a Buyer Offer Release Funds and Leave Feedback Create a New Child Currency Field: Transaction type Valid values: Omni Protocol transactions are not reversible except as explicitly indicated by this spec.
Transferring coins Transfers are unconditional payments from one Omni address to another address, set of addresses, or proportionally to owners of a specific property. Transfer Coins Simple Send Description: In addition to the validity constraints on the message field datatypes, the transaction is invalid if any of the following conditions is true: The data stored is: See Currency Identifier , above.
The message to do so will use 16 bytes: Distributed Exchange The Omni Protocol allows users to trade coins without trusting a centralized website. Sell Mastercoins for Bitcoins Description: Doing this takes 34 bytes: When canceling a sell offer, the values in the following fields are not tested for validity: Amount for sale Amount of bitcoins desired Time limit in blocks Minimum bitcoin transaction fee The cancel will apply to the amount that has not yet been accepted.
Purchase Mastercoins with Bitcoins Description: Doing so takes 16 bytes: New Order Amt for Sale Existing Order Min Amt Desired Amt Transferred Liquidity Bonus Paid New Order Remainder for Sale Existing Order Remainder Desired 3 0 0 3 0 3 2 0 2 1 0 1 0 1 0 0 0 0 25 0 The coins from each matching order and the new order are exchanged between the corresponding addresses at the unit price specified by the matching order plus the liquidity bonus amount until the full amount for sale in the new order is transferred to the address of the matching sell order or there are no more matching orders.
Notes on rounding, with me the new order purchasing from Bob the existing order: First determine how many representable indivisible tokens I can purchase from Bob using Bob's unit price This implies rounding down, since rounding up is impossible would require more money than I have Example: Rounding in the other direction will always be impossible would violate Bob's required price If the resulting adjusted unit price is higher than my price, the orders did not really match no representable fill can be made Example: An existing order matches the new order when all of the following conditions are met: Doing this takes 29 bytes: An offer to sell coins can be changed or cancelled by publishing additional transactions with Metadex Sell offer sub-action variations: Currency identifier for sale Amount for sale Currency identifier desired Amount desired Any time coins are added, whether merged with another order or not, the same matching process is run as for a new order as described above.
Smart Property The Omni Protocol supports the creation of property tokens to be used for titles, deeds, user-backed currencies, and even investments in a company.
To indicate that the issuer is abandoning a property entirely: In addition to the validity constraints for each message field type, the following conditions must be met in order for the transaction to be valid: This example uses 80 bytes: The crowdsale is active until any of the following conditions occurs, which causes the crowdsale to be closed permanently: The "Percentage for issuer" value is used to calculate the number of additional tokens generated and credited to the issuer's address as follows: The following expression may be used to calculate the maximum number of tokens that are available for purchase such that the current early bird bonus percentage and the Percentage for issuer can be applied without exceeding the maximum number of tokens that can be issued: MaxNum is the maximum number of tokens that can be issued Issued is the number of tokens issued prior to this purchase In addition to the validity constraints for each message field type, the following conditions must be met in order for the transaction to be valid: This example uses bytes: This is accomplished, while the crowdsale is active, by the crowdsale owner's address sending additional Transaction type 51 messages with: Participating in a Crowdsale Participating in a crowdsale is accomplished by sending coins of one of the desired currencies to the crowdsale owner's address with the Simple Send transaction or a bitcoin Send transaction if the crowdsale accepts bitcoins currency id 0 for purchases.
