Deep Dive into Money On Chain

This document provides an opportunity to fully immerse yourself in the Money On Chain protocol, gain a comprehensive understanding of the tokens, and discover the rationale behind our decision to utilize Bitcoin as collateral.

Brief description: What’s Money On Chain?

Money On Chain is a comprehensive and trust-minimized protocol designed to empower Bitcoiners to explore new avenues for using Bitcoin, while maintaining full control of their private keys. The protocol comprises several features, including a stablecoin, liquidity token, governance protocol, and more.

Money On Chain's innovative approach is rooted in a risk-sharing mechanism that is made possible by a proprietary financial model. This model has been extensively developed and tested, demonstrating robustness even in the face of extreme market conditions.

In 2019, Money On Chain launched a Stablecoin Protocol on RSK (Rootstock), which includes two tokens. The first is the Dollar on Chain (DoC), a stablecoin that is 100% collateralized in BTC, designed for Bitcoiners who wish to hold the current value of their bitcoins in USD terms. The second is BPRO, a token that offers leverage to Bitcoiners, providing passive earnings while retaining full control of their private keys.

The protocol also includes three other components: a decentralized token exchange known as TEX, operating on RSK, decentralized oracles named OMoC, and the MoC token that provides governance to the protocol, staking rewards, and protocol fees.

Let's explore Money On Chain in greater depth.

The Problem

Bitcoin's rapid growth is causing significant disruptions in the traditional financial system. However, for a currency to be widely adopted for everyday transactions in society, it must fulfill three key functions - serving as a medium of exchange, a unit of account, and a store of value. Unfortunately, Bitcoin's extreme volatility undermines its ability to serve these functions effectively.

Figure 2: Bitcoin Volatility Time Series Chart

To address the problems caused by volatility, stablecoins have been developed as a solution. These digital assets are designed to replicate the value of fiat currencies, like the dollar or the euro, and enable fast and cost-effective transfers globally while maintaining price stability.

Prior to the advent of Bitcoin, the only means of digital value transfer was through intermediaries like banks. However, Bitcoin disrupted this model by eliminating the need for intermediaries.

While Bitcoin is an excellent medium of exchange from a technical perspective, its value fluctuations make it less suitable for payments. The coins may be worth significantly more or less than at the time of the transaction by the time they are settled.

Stablecoins, on the other hand, have resolved the issue of volatility but have introduced new concerns, such as counterparty risks, particularly when using fiat currencies as collateral or less established crypto assets as collateral. Immutability, a characteristic unique to Bitcoin, makes it a more appealing option for collateral over other crypto assets. Immutability refers to the fact that there is a preset limit of 21 million bitcoins and a decreasing issuance rate, allowing for some predictability about the future. The 21 million bitcoins limit also ensures scarcity.

Money On Chain presents an innovative solution that addresses Bitcoin's volatility issue.

The Solution

Money On Chain is a protocol that has been developed to address the issue of Bitcoin's volatility. The protocol allows for the creation of a stablecoin that is collateralized with Bitcoin, using a two-party system approach.

stablecoin protocol
Figure 3: Stablecoin Protocol

The Money On Chain protocol offers several tokens designed to cater to different needs of Bitcoin users.

Firstly, the Dollar on Chain (DOC) is a trust minimized stablecoin that is pegged 1-to-1 with the USD and is backed by Bitcoin as collateral. The peg is secured by a smart contract, which guarantees that a user can redeem 1 DOC for the equivalent value of 1 USD in rBTC, Smart Bitcoin, at any given moment.
Secondly, the BPRO token is built using Bitcoin and offers free leverage provided by DOC token holders. This means that the price of BPRO will increase with the price of Bitcoin (and decrease vice versa) due to the leverage. Additionally, BPRO tokens receive 20% of the fees charged in the protocol when users mint or redeem DOC or BPRO tokens. This passive income in Bitcoin increases the value of BPRO. Furthermore, the BPRO token also receives MoC tokens through a Liquidity Mining program.

Tokens in more detail

Dollar On Chain (DOC)

The DoC is a token that is pegged to the value of the USD dollar, meaning that its value is always equal to one US dollar. This peg is ensured by a smart contract. Holders of DoC tokens can redeem them for smart bitcoins (rBTC). 

DoC tokens are also highly versatile, as they can be easily transferred and stored in hardware wallets. In addition, DoC tokens can be exchanged on decentralized exchanges like Money On Chain's TEX, as well as on other secondary markets. 

Users must pay a fee to issue or redeem DoC tokens.


The Money On Chain protocol was specifically designed to cater to bitcoin Hodlers, and careful consideration was given to evaluate various incentive alternatives to increase contributed collateral to the protocol.

BPRO is a token designed for long-term BTC holders, which enables them to leverage their bitcoin holdings. Moreover, BPRO tokens appreciate in value by earning a portion of the fees charged to users minting or redeeming DOC or BPRO.

Here are some key features of BPRO:

  • Free Leverage: BPRO token holders can enjoy leverage provided by the DoC token holders. As the price of BTC rises, BPRO price also increases further.
  • Fees: BPRO token holders earn a portion of the fees paid by users to issue DoC and BPRO. 20% of these fees are transferred to BPRO, thereby increasing the token's value.
  • Costs: BPRO tokens incur an annual fee of 1% of their value, which is deducted on a weekly basis and paid to the MoC protocol.
  • Tradeable: BPRO tokens can be traded on the Money On Chain decentralized token exchange (TEX), other secondary markets, or redeemed for smart bitcoins against the smart contract.
  • Your keys, your coins: BPRO tokens can be stored securely in your hardware wallet.
  • MOC Liquidity Mining: Money On Chain has issued a third token, the Money On Chain Token (MoC), which is a governance token. MOC Liquidity Mining is an incentive program that rewards bitcoiners holding their positions in BPRO tokens. For more information about the program, please visit this article: https://moneyonchain.com/blog/money-on-chain-rewards-explained/
  • BPRO token holders have the ability to monitor the daily amount of MoC tokens assigned on the platform.

Token Exchange

A decentralized token exchange (TEX) allows bitcoiners to trade tokens on the RSK Blockchain using a unique mechanism. Unlike traditional cryptocurrency exchanges, TEX is inspired by The London Gold Fixing method. You can find more information about TEX in this article: https://moneyonchain.com/blog/tex-the-decentralized-token-exchange-by-money-on-chain/

Money On Chain Oracles - OMoC

The MOC Protocol incorporates Oracles known as OMoC, which provide data (primarily BTC price) to the protocol and other Smart-Contracts that require it. OMoC offers several unique features that distinguish it from other currently available Oracles. Firstly, it is a hybrid protocol, comprising an off-chain and an on-chain component, enabling updates to be made to the information in all blocks. Secondly, it can be utilized by other projects/Smart-Contracts directly and is accessible as a service for other projects/Smart-Contracts.

To operate an OMoC node, a minimum stack of 250,000 MoCs is mandatory. Economic incentives are offered to encourage individuals to run OMoC nodes. OMoC nodes receive income from various sources such as 80% of the fees charged in the MOC protocol for minting and redemption of tokens (DoC, BPRO), a percentage of the decentralized token exchange (TEX) fees, and other Smart-Contracts that use OMoC. MoC holders running OMoC nodes also receive a portion of the MoC issued as MOC Rewards.

How does the protocol work? - Example with Alice and Bob

Suppose Alice is a long-term Bitcoin holder who is interested in the benefits of the Money On Chain protocol. By using her Bitcoin as collateral, Alice can mint BPRO tokens through the protocol. This provides liquidity for the issuance of DOC tokens, which can be used for various purposes.

On the other hand, Bob may not be as willing to take on risk as Alice. However, he can still take advantage of the Money On Chain protocol by using his Bitcoin to mint DOC tokens. In this case, Bob's DOC tokens will be backed by Alice's collateral. By using his DOC tokens for payments, Bob can enjoy a predictable value for his transactions.

In summary, the Money On Chain protocol allows both risk-averse and risk-tolerant users to participate in the protocol by using their Bitcoin to mint tokens.

Figure 4: How does the protocol work? - Example with Alice and Bob

Moment 1 - price of one bitcoin is USD 10,000

In this example, let's say the price of one bitcoin is initially USD 10,000. 

When the Money On Chain protocol starts, the price of BPRO will be the same as Bitcoin, meaning 1 BPRO will also be worth 1 BTC, or 10,000 USD.

Alice provides liquidity by minting 7 BPRO tokens with 7 bitcoins, bringing the Total Value Locked (TVL) to 7 BTC or 70,000 USD. 

Bob needs Stablecoins and mints the equivalent of 1 bitcoin, receiving 10,000 DOC tokens.

The TVL increases to 8 bitcoins or 80,000 USD.

Figure 5: price of one bitcoin is USD 10,000

Moment 2 - Bitcoin Price Hits USD 20,000.

A year later, the price of 1 BTC increased by 100%, bringing it to USD 20,000. However, no one had withdrawn their position in the protocol.

As a result, Bob still has the equivalent of 10,000 USD. Had he retained his original 1 BTC, he would now have USD 20,000. This begs the question: where did the missing 10,000 USD go?

The answer is Alice, who held BPro and utilized leverage. Her BPro is now valued at USD 150,000, compared to USD 140,000 if she had held onto her bitcoins.

At this point, 1 BPro is valued at 1.07 BTC, or 21,428 USD.

Despite this, the Total Value Lock remains at 8 bitcoins, but now valued at the equivalent of 160,000 USD.

Figure 6: price of one bitcoin is USD 20,000

Moment 3 - Bitcoin Price Drops to USD 5,000.

One year later, the price of Bitcoin plummeted to $5,000. Despite this, no user withdrew their position in the protocol. As a result, Bob still possessed the equivalent of $10,000. However, had he kept his original one Bitcoin, he would only have had $5,000. The question then arises: where did the additional $5,000 come from?

The answer lies with Alice, who had utilized her BPro to gain some leverage. At this moment, Alice's BPro was valued at $30,000, rather than the $35,000 it would have been worth had she retained her Bitcoins and not minted BPro.

As a result, one BPRO was valued at 0.85 BTC, or $4,285. The Total Value Lock remained at 8 Bitcoins, but their equivalent value was now $40,000.

Figure 6: price of one bitcoin is USD 5,000

Illustrating the behavior of the model in terms of bitcoins

The following graph illustrates the behavior of the model in terms of bitcoin. It is based on a starting point price of USD 10,000 per bitcoin, with 8 bitcoins in the protocol. It is observed how the model behaves after a 100% increase in the price of bitcoin. and after a 50% price drop. The protocol always maintains a fixed supply of 8 bitcoins. Any fluctuations in the USD value of bitcoin simply result in a redistribution of these bitcoins among the protocol's users.

Figure 7: Illustrating the behavior of the model

Platform Users

Within Money On Chain architecture, we distinguish the following Platform users (some users may have more than one role, that is, it may be a MoC holder and a stablecoin holder):

  • Stablecoin User: a bitcoiner who does not want to be exposed to the volatility of a cryptocurrency, so he prefers to own a token that follows the price of a fiat currency
  • Bitcoin Holder: bitcoiner who holds their bitcoins for the long term and seeks some free leverage on their bitcoins.
  • MoC Holder: a user who holds MoC, which allows him to participate in the governance of the platform and / or provide a service to it in exchange for receiving rewards and part of the fees collected by the platform.
  • Any RSK Token (ART) Trader: a user who owns a token compatible with the RSK Blockchain (could be BPRO, DoC, MoC, rBTC, RIF, etc), and wants to perform a decentralized exchange operation.

Why Choose Bitcoin as Collateral?

Bitcoin is widely recognized as the most liquid and secure cryptocurrency with the largest market capitalization and user base. Its protocol prioritizes stability, robustness, and immutability over new features that could potentially compromise network security. Additionally, Bitcoin boasts the most significant cryptographic mining power among all cryptocurrencies. These qualities make it the safest payment system available.

Moreover, Bitcoin's decentralization is its most significant advantage, as it ensures that no entity has the power to change its governing rules without consensus among its users, miners, developers, and companies. This unique quality is often overlooked and underappreciated.

Furthermore, the clarity of Bitcoin's monetary policy is another critical factor in choosing it as collateral over other cryptocurrencies. Its policy is immutable, with a pre-established limit of 21 million bitcoins and a decreasing rate of emission, which allows for anticipation of future trends. Additionally, the 21 million token limit ensures scarcity, and Bitcoin is deflationary since its supply decreases when Bitcoins are lost due to hardware damage, lost wallets without backups, death of holders without instructions to heirs, among other reasons.

Given these features, it is not surprising that Bitcoin is the most secure, popular, and widely used cryptocurrency payment system in the world. Rather than attempting to compete with it, we believe that leveraging its strengths to our advantage is a much smarter and efficient strategy.

Why create another stablecoin?

Money On Chain offers a unique solution that sets it apart from other stablecoins in several ways: 

  • Firstly, it is the first stablecoin protocol that is Bitcoin-collateralized, providing a more secure approach. 
  • Additionally, the model is simple, yet versatile, catering to the needs of different users. The protocol includes tokens for both risk-averse individuals and long-term Bitcoin holders. 
  • The high demand for this type of solution in the Bitcoin ecosystem is evidenced by the use of imperfect alternatives already in the market. Furthermore, the widespread adoption of the protocol positively impacts the Bitcoin community by increasing demand and, consequently, its value. 
  • Money On Chain is an open-source software that runs on a Bitcoin Sidechain, eliminating counterparty risks. Each user is solely responsible for complying with the laws and regulations in their respective country when interacting with the smart contract. 
  • Lastly, the solution utilizes RSK technology at a large scale, making it a pioneering application in the Bitcoin ecosystem. The decentralized network of Bitcoin miners provides an additional layer of security to the protocol.


The Money On Chain Token (MoC)

The Money On Chain Token (MoC) serves multiple purposes on the platform, including:

  • Governance: By staking MoC, users gain the ability to vote on and veto proposed updates to the platform.
  • Fees Revenue Stream: MoC holders can stake their tokens to earn platform fees and staking rewards.
  • Oracle: MoC holders can also run an oracle node for an additional source of revenue.

Platform Fees Discount: Holders of MoC can enjoy an additional discount when paying platform fees using their tokens.

Platform Fees

Each time someone uses Money On Chain’s protocol a small fee is paid. Users pay that fee in Smart Bitcoin that will is collected and sold for MoCs in the Money On Chain Decentralized Exchange (TEX). The result of that sale is distributed, according to rules established in the Smart Contract, among:

  • MoC holders stacking their MOCs
  • Node operators
  • BPRO Collateral holders

Governance Rules

MOC’s holders have the power to vote and veto the platform updates, in a way that any change that might affect the interests of the MoC´s holders, shall not be implemented without a majority of such MoCs´ holders voting in favour of those changes.

Any change to the smart contract may be proposed by any MOC´s holder as long as such holder has at least 1% of circulating supply. 

Only Staked MoCs can vote.

To be valid, any voting procedure require a quorum equal to –at least- twenty percent (20%) of all circulating and outstanding MoCs.

In order to be approved, a proposal shall require the affirmative vote of — at least — the majority of MoC´s holders; provided, however, that a proposal which has obtained negative vote of — at least — thirty percent (30%) of the total amount of the MoCs issued and outstanding at the time the voting procedure expires, in that case the vote shall not be approved and, therefore, will be considered as rejected. If MoC total Market CAP is smaller than total BPRO Market CAP, the BPRO holders will be able to veto with 30% of total BPRO in circulation (only vested BPRO tokens will be able to veto).

Risk Factors

Our model is subject to several risks, which we propose to mitigate through a series of actions. These risks relate to:

  • Volatility: Bitcoin volatility may differ from expectations. A number of unforeseen events and/or irrational market dynamics could potentially cause variation in the value of Bitcoin for an extended period of time, affecting the value of the tokens offered by the platform. If confidence is lost in the system, volatility could reach extreme levels while still not bringing enough liquidity and stability to the market.
  • Demand and Liquidity Risk: The demand for DoCs and BPRO may grow at different rates than expected. Such circumstances may affect the use of the platform and, as a result, the value of the tokens offered herein. Such an event may affect the liquidity of such tokens as well as the MoC tokens used for paying the fees in the platform, possibly preventing the token holders from selling out of these illiquid tokens at an advantageous price. In addition, liquidity risk tends to increase to the extent that the sale or purchase of the tokens is restricted by law or governmental authorities.
  • Management: The company developing the protocol, and its management team, play a major role in the development and governance of the platform in its early days: budgeting for expenses, hiring new developers, seeking partnerships and institutional users, and interfacing with regulators and other key external third-parties. Should the company fail in some capacity — for legal reasons, or due to internal problems with management — the future of the protocol could be at risk without a proper backup plan. It must be noted that the management team includes experts in technology, finance, law, digital marketing, and entrepreneurship with vast experience in the corporate world to enable launching and operating the project successfully. Notwithstanding that, the management team may not be able to manage the project appropriately.
  • Model and Competition: There is a large amount of money and brainpower working on stable coins, each of which offers different features to the users. As explained herein, we believe that the Money on Chain system offers solutions which are different from the existing stablecoins, with the potential to attract many users of the Bitcoin environment, which will allow the system to grow fast. Nevertheless, there is no assurance that the management team’s view will be shared by the cryptocurrency users, which may imply such users choosing to operate with other stablecoins different from those offered by the platform. We expect that DoC and BPRO will be very easy to use for regular cryptocurrency users. DoC and BPRO have been designed in such a way that the average user need not understand the underlying mechanics of the system in order to use it. Notwithstanding the foregoing, the management team’s model design may be flawed and fail to cope with all possible real-world challenges.
  • Infrastructure and Security Risks: Smart contract security and best security practices have been the absolute highest priority of our development effort since its inception. Notwithstanding that, the smart contract, the RSK network or the Bitcoin network infrastructure could fail or be hacked. The greatest risk to the system during its early stages is a malicious programmer finding an exploit in the deployed smart contracts and using it to break or steal from the system before the vulnerability can be fixed. In a worst-case scenario, all the Bitcoins that are held as collateral in the platform could be stolen without any chance of recovery.
  • Black swan event in one or more collateral assets: Another high impact risk is a potential Black Swan event on Bitcoin used as collateral for the D0Cs and BPROs. This could either happen in the early stages of the platform, before the system is robust enough to support a sudden fall of the Bitcoin`s price. In case a black swan takes place, the system will put in place several mechanisms in order to prevent the platform to liquidate the smart contract. Among other mechanisms that may exist, the system will have an “Emergency Shutdown”, which is a process that can be used as a last resort in case we believe that the stability of the Money on Chain ecosystem is threatened. After the Emergency Shutdown is triggered, all the transactions in the stable coin system and the exchange (excluding cancelation of orders in the exchange platform) shall be frozen until the Emergency Shutdown is disabled. DoC and BPro transfers are not affected by this action. In the worst-case scenario, DoC’s holders will receive an amount in Bitcoin equal to the amount of DoC held by each holder at the time in which the liquidation of the smart contract occurs, and the remaining participants (BPRO´s holders), will lose their investment.
  • Regulatory issues: Regulators may declare Bitcoin, RSK, or MOC tokens illegal in any jurisdiction. Such circumstances may prevent users from such jurisdiction to purchase or sell the tokens offered herein, restricting the growth of the system and could affect the performance of the platform in a way that is disadvantageous to users.
