# Fact, Vision & Mission ## The Fact The global banking system is inadequate to meet the needs of the 21st century consumer in emerging economies as evidenced by the fact that **1.7 billion adults remain unbanked**, while those that are banked are unable to pay cross-border, in their local currencies. ## Our Vision To maximise human economic potential. ## Our Mission To create an alternative global commerce ecosystem that does not require a financial institution for payment processing. To empower everyone to control all their assets, all the time, for true financial sovereignty. To create an equitable, inclusive, and currency-agnostic commerce ecosystem. # Whitepaper 📃 [Whitepaper ↗](https://boom.market/whitepaper.pdf) {% embed url="" %} Boom Whitepaper {% endembed %} # Team The Boom Superapp is owned and operated by Boom Technologies Ltd, a UK company registered in England and Wales with company number 15034868 and registered offices at 71 - 75 Shelton Street, Covent Garden, London WC2H 9JQ. 👥 # Join us Boom is on a mission to make commerce more equitable and inclusive for all of humanity.

Boomcoin is the native asset of the boom blockchain, the base currency of Boomswap that all stablecoins are traded and routed against and the **medium-of-exchange for goods and services in the Boom superapp**. * Total maximum supply: **2 billion** (All pre-mined) * Global disbursement to Boomswap Liquidity Providers in 150 Countries: **1.50 billion** * Boom Team & investors allocation: **450 million** * Boom Foundation: **50 million**

Boomcoin (BMC)

Boomcoin’s total supply is permanently limited to 2 billion and as such, it can be used as a store of value to hedge against fiat inflation. {% hint style="info" %} BMC can be purchased p2p directly within the [Boom wallet](https://boom.market/super-app), [hATM network](/ecosystem/hatm), on [Boomswap](https://boomswap.org/), [Boomfaucet](https://faucet.boomswap.org/) and from liquidity merchant partners globally with cash, bank transfer or with crypto. {% endhint %}
Why is Boomcoin unique compared to other cryptocurrencies? Boomcoin is a unique cryptocurrency because its value is derived from its multiple utility. Boomcoin is the native asset of the Boom blockchain in which all transaction fees are paid, it is the base currency on Boomswap that all stablecoins are traded against, and it is the medium-of-exchange for goods and services in the Boom superapp.
Is Boomcoin Political? No, Boomcoin is politically and financially neutral.
How does Boomcoin avoid Centralisation? To avoid the centralisation of Boomcoin within one market or jurisdiction, BoomDAO is distributing 75% of its total supply i.e. 1.5 billion BMC, to liquidity Providers at the rate of 10 million per country across 150 countries worldwide. This avoids centralisation and ensures that people in all countries benefit from its utility and created growing value.
How does Boomcoin compare with other leading cryptocurrencies? Boomcoin has been labelled “the Bitcoin for everyday commerce” because of its multiple utility and limited supply.
# Boom Wallet The Boom Wallet enables you to **send, receive, scan-to-pay, fund and receive money instantly and with no fees whatsoever**.

Boom Wallet

Boom has transformed the world into a single market with the Boomcoin as the router-of-value between fiat currencies. This means that on Boom you can pay and get paid across borders in your local currency. Boom Wallet can be funded with cash directly from the Boom App. Simply tap on “Fund” and follow the instructions. See the [Boom hATM section](/ecosystem/hatm) for more. #### Can I withdraw funds from my Boom Wallet to my bank? Yes! In the near futur you will be able to cash-out local currencies in-person or withdraw it to your bank at any time. # hATM **A Boom human ATM (hATM)** is someone who helps Boom users cash in and cash out of their Boom wallets for a fee. hATM are visible on a map for users to find them. {% hint style="success" %} Boom uses a secure escrow mechanism to protect both hATMs and users during transactions. {% endhint %} The benefits of becoming a Boom hATM are: * Earning commission on every transaction you complete. * Set your own hours and work from your preferred location. * Increase foot traffic to your business (if applicable). Boom users can pay in cash or via various methods like wire transfers, credit/debit cards, or cryptocurrency.
How do I become a Boom hATM? First, you must be 18+ and have a valid government-issued ID. Then:\ • Open the Boom app. \ • Click the radio icon on the top left corner (wallet section). \ • Enable location services. \ • On the map, click the radio icon on the top right corner. \ • Enable the "I agree to be a Boom hATM" button. \ • Alternatively, enable it through your merchant profile.
What is a typical hATM commission rate? Boom recommends charging a commission of 0-5% per transaction and emphasizes ethical conduct.
What documents do I need to become a Boom hATM? • Individuals: Valid government-issued ID card.\ • Businesses: Valid business registration ID.
What happens if a user cancels a transaction after I accept it? The escrow protects you. The user won't receive their cash/BMC until they complete the transaction.
How do I get notified about potential transactions? hATMs within a 50km radius of a user requesting a transaction will receive a push notification.
If you're planning to handle high-volume transactions, you should consider becoming a [Boom Super hATM](/ecosystem/hatm/super-hatm). # Super hATM **Super hATMs** cater to large-scale transactions for big businesses on Boom. They require a currency trading license. Super hATMs **handle high-volume transactions, leading to higher earnings**. Requirements to become a Boom Super hATM are: * Business registration certificate and license. * Proof of business address. {% hint style="info" %} hATM can manage their availability within the app at any moment. {% endhint %} {% hint style="success" %} Boom has measures to identify and penalize fraudulent activity. Users can also report suspicious hATMs. {% endhint %} ### Escrow Mechanism The escrow mechanism acts as a trusted third party during transactions. It holds the funds securely until both parties (hATM and user) confirm the transaction's completion. When a transaction starts, Boom holds the user's funds in escrow until they complete the cash exchange with the hATM.
What happens if a user disputes a transaction? Boom's escrow system and dispute resolution process will be engaged to determine the outcome.

Boom Marketplace

For merchants, you should sell on Boom because: * You get paid instantly rather than waiting for days. * There are no listing fees on Boom. * There are no subscription fees on Boom. ### Payments The global medium-of-exchange for goods and services on Boom is the Boomcoin (“BMC”) token. So, merchants list their goods and services in their local currencies and consumers purchase goods and services also in their local currencies. And whenever a selling currency is different from a purchasing currency, Boom initiates the swap via BMC. Therefore merchants list their products in their local currencies and get paid in their local currencies. The Boomcoin token simply transmits value between merchants and consumers after which it is converted to local currencies. This ensure that merchants are immune to token price volatility always. ### After-sales service If your order never arrived call or contact the seller via Boom Talks. Same process if you want to arrange the return, the seller will credit your Boom Wallet with your refund. # Boom Pay [**Boom Pay**](https://boom.market/solutions/boom-pay) **is the payment gateway that enables you to collect online payments from 2 billion unbanked consumers.** 1.7 billion adults globally lack access to the world of online shopping because they have no bank account.

{% content-ref url="/pages/wthnEpec7yQZaR4TjyqR" %} [Boomscan APIs](/apis/boomscan-apis) {% endcontent-ref %} # Boomswap [**Boomswap**](https://boomswap.org/) **is a self-custodial decentralised exchange where all the world's currencies are tokenised and traded, peer-to-peer**. It is made up of persistent smart contracts that run on the Boom blockchain and utilises an automated market maker model instead of traditional order-book based models. Boomswap has no single centralised authority that runs it and is **seizure and censorship resistant**, **forever**. > On Boomswap, anyone can create or fund a liquidity pool and **earn trade fees of 1.60%** on all swaps. To create or add liquidity to a pool, you will need an equivalent amounts of both assets. **Boomswap was created to foster cross-border trades, especially in emerging markets where 90% of all trades are settled in cash, by enabling instant payments in tokenised local fiat currencies**. To achieve this, [BoomDAO](https://boomdao.org/), the non-profit organisation that created Boomswap, has tokenised all the fiat currencies of the world into stablecoins that are backed and redeemable 1-to-1 by deposits in each country. This ensures seamless fiat off-ramp at scale because Boomswap's liquidity is backed by the most liquid asset of all, cash. Tokenising cash expands its utility into DeFi which injects international demand and liquidity into them, reduces settlement costs, while enhancing transaction transparency, traceability and security.
How is Boomswap different from other decentralised exchanges? Unlike other decentralised exchanges, all the stablecoins on Boomswap can be off-ramped into goods, service and banks worldwide.
Are all Boom Stablecoins Backed by Fiat? Yes, all the tokenised assets traded on Boomswap are backed and redeemable 1-to-1 by physical deposits of the underlying real world asset. For example, in order to mint a Boom tokenised Euro, €1 in fiat must first be deposited in a bank in the euro-zone.
How do I Fund my Wallet with Boomswap Stablecoins? Boomswap stablecoins can be acquired on Boomswap or from BoomDAO merchants.
How do I cash-out from Boomswap to my Bank? Boomswap is the first decentralised exchange where users can swap fiat (on-ramp) for tokenised fiat and swap tokenised fiat directly back into their banks (off-ramp) in any of the supported currencies, instantly.
Is Boomswap compliant with regulations on Money Laundering? While Boomswap is a self-custodial decentralised exchange that anyone can access, off-ramping to fiat is only possible at scale via banks. This ensures that customers that are off-ramping are already bank-regulatory compliant.

Liquidity pools are intended to replace traditional order books by directly matching buyers and sellers. They are the backbone of DeFi platforms, bringing together people eager to supply their assets and people looking to trade or borrow those assets. Participants contribute to a shared pool of liquidity by depositing tokens into a liquidity pool, which ensures the continued availability of assets for trading, lending, and other financial operations. ## Liquidity Provision A Boomswap liquidity pool is the trading arena for a pair of tokenised fiat currencies. Anyone can create a pool and once created, the balance of each token is zero. In order for the pool to begin facilitating trades, someone must seed it with an initial deposit of each token. This first liquidity provider is the one who sets the initial price of the pool. Whenever liquidity is deposited into a pool, unique tokens known as *Boomswap LP Tokens* (LP Tokens) are minted and sent to the LP’s wallet. **These tokens represent a given LP’s contribution to a pool**. The proportion of the pool's liquidity provided determines the number of liquidity tokens the provider receives. If the provider is minting a new pool, the number of liquidity tokens they will receive will equal √(x \* y), where x and y represent the amount of each token provided. Whenever a trade occurs, a 1.60% fee is charged to the transaction sender. This fee is distributed pro-rata to all LPs in the pool upon completion of the trade. **To retrieve the underlying liquidity, plus any fees accrued, LPs must redeem their LP Tokens for the underlying assets and earned fees when removing liquidity from a pool.** {% hint style="info" %} As LP tokens are themselves tradable assets, liquidity providers may sell, transfer, or otherwise use their LP tokens in any way they see fit. {% endhint %}
What fees do Liquidity Providers (LP) earn on Boomswap? Liquidity providers earn a 1.6% fee on all swaps that utilise their pool as a reward for supplying their tokens to inject liquidity to pools. This fee is deducted from the input token and is paid proportionally to all LPs that have an active liquidity position. Liquidity provider fees are paid entirely to LPs and BoomDAO does not receive any of these fees.
What other fees are deducted from trades? In addition to LP fees, a 0.3% protocol fees is retained. So, in total, all swaps incur a 1.60% liquidity provider fees and a 0.30% protocol fees that goes to BoomDAO.
Are fees Auto-Compounded into Pools as they are Earned? Yes, earned LP fees are auto-compounded into the pool, meaning that with every swap, the fees go back into the pool making it bigger.
Who can be a Liquidity Provider on Boomswap? Anyone can be a liquidity provider as long as they have the base currency, BMC and an equivalent amount of another asset.
How do I Withdraw my Liquidity Position? Go to pools, connect your wallet and click withdraw liquidity on the Boomswap app
# Developer Boomswap is a [Uniswap V2](https://docs.uniswap.org/contracts/v2/overview) fork. Developers can interact with Boomswap in the same way they use Uniswap repositories and SDKs. {% hint style="info" %} Boomswap has a total **fee structure** of **1.9%** from which 0.3% goes to the protocol. {% endhint %} The following steps were made when forking the original code: ## V2-Core-Master Module ### Contracts and Modifications * **BoomswapERC20.sol** : Originally [`UniswapV2ERC20`](https://docs.uniswap.org/contracts/v2/reference/smart-contracts/Pair-ERC-20), this contract has been modified for LP name and symbol adjustments. * **BoomswapPair.sol** : Originally [`UniswapV2Pair`](https://docs.uniswap.org/contracts/v2/reference/smart-contracts/pair). Fee value in updated in the `BoomswapPair-swap()` function at these two lines: ```solidity // 19 = 1.9% fee uint256 balance0Adjusted = balance0.mul(1000).sub(amount0In.mul(19)); uint256 balance1Adjusted = balance1.mul(1000).sub(amount1In.mul(19)); ``` * **BoomswapFactory.sol**: Formerly [`UniswapV2Factory`](https://docs.uniswap.org/contracts/v2/reference/smart-contracts/factory). Key modification includes the initialization of the state variable `INIT_CODE_HASH`. The deployment of this contract requires a specified `_feeToSetter` address, which has the authority to adjust the `feeTo` parameter. ## V2-Periphery-Master Module ### Implementation Steps 1. Retrieve the contract address and `INIT_CODE_HASH` from the deployed Factory. 2. In [`UniswapV2Library.sol`](https://docs.uniswap.org/contracts/v2/reference/smart-contracts/library), replace the existing init code hash in the `pairFor` function (Remove the '0x' prefix). 3. Compile and deploy the `IUniswapV2Router02` and **`BoomswapRouter.sol`** contracts (previously [`UniswapV2Router02`](https://docs.uniswap.org/contracts/v2/reference/smart-contracts/router-02)) using the appropriate pragma solidity version. 4. **BoomswapRouter Deployment**: Requires the `_FACTORY` address and the WBMC address (formerly WETH). Consider modifying `UniswapV2Library.sol` and `UniswapV2LiquidityMathLibrary.sol` fees initially at 0.3% (997/1000). {% hint style="danger" %} Don't subsitute WETH with WBMC.

Download Besu You can download the latest version of Hyperledger Besu from the [official releases page](https://github.com/hyperledger/besu/releases) : [packaged binaries](https://github.com/hyperledger/besu/releases). ```bash wget https://hyperledger.jfrog.io/artifactory/besu-binaries/besu/24.1.1/besu-24.1.1.zip ``` Once downloaded, extract the archive to a directory. ```bash unzip besu-24.1.1.zip ``` Change into the besu- directory. ```bash cd besu-24.1.1/ ``` To confirm installation: ```bash bin/besu --help ``` ```bash bin/besu --version ``` To run besu as a command go to .bashrc. ```bash nano .bashrc ``` Add this line: ```bash export PATH=$PATH:/pathTO/besu-24.1.1/bin ``` ```bash source .bashrc ``` Verify: ```bash besu --help ``` ```bash besu --version ```
## Get Started
Initialize Node Directories 1. Create a directory ```bash mkdir -p network/node1/data ``` ```bash cp network/node1/data ``` 2. Generate a Node Key for the New Node ```bash besu --data-path=data public-key export --to=data/key.pub ```
### Copy the Genesis File The new node needs to be initialized with the same genesis file as the rest of the network. Copy the `genesis.json` file. ```bash cd network/node1 ``` {% tabs %} {% tab title="Testnet" %} Download the Testnet `genesis.json` file. {% file src="/files/yrAI5AAHrYlETJPqLlOg" %} Testnet Genesis {% endfile %} {% endtab %} {% tab title="Mainnet" %} Download the Mainnet `genesis.json` file. {% file src="/files/UJEZ5u62AHxfNPV4ZKTI" %} Mainnet Genesis {% endfile %} {% endtab %} {% endtabs %} ### Create `config.toml` Configuration Files ```bash cd network/node1 nano config.toml ``` {% tabs %} {% tab title="Testnet" %} {% code title="Exemple of Configuration" %} ```toml # Valid TOML config file data-path="data" # Path #static-nodes-file="data/static-nodes.json" # Network bootnodes=["enode://23b6a539306cc1f3a61230e3253cebf9b6cad37fa045954fe27cef265ab232329456c786d16d6c132eaf957b75f5e87629ec7e6a7aa271e9c346b2cde2e0a4d0@95.111.219.167:30301"] #p2p-host="0.0.0.0" p2p-port=30305 max-peers=42 host-allowlist=["*"] [sync] #sync-mode="X_SNAP" # Enables Snap sync logging="DEBUG" min-gas-price=0 revert-reason-enabled=true rpc-http-enabled=true #rpc-http-host="0.0.0.0" rpc-http-port=22005 rpc-http-cors-origins=["*"] rpc-http-api=["ADMIN", "ETH", "NET", "WEB3", "QBFT"] #rpc-ws-host="0.0.0.0" rpc-ws-enabled=true rpc-ws-port=32005 rpc-ws-api=["ADMIN", "ETH", "NET", "WEB3", "QBFT"] # Chain genesis-file="genesis.json" # Path to the custom genesis file ``` {% endcode %} {% endtab %} {% tab title="Mainnet" %} {% code title="Exemple of Configuration" %} ```toml # Valid TOML config file data-path="data" # Path #static-nodes-file="data/static-nodes.json" bootnodes=["enode://39f394a6c9bec694d2c7dc5b1c5b20611fbfb9212a5f75c28febdff92eb290ea7ec1c5a3873d7e14a32ec3bc7072f52ef4dfbf9c7387c8315b9d3a5b48e981df@94.237.66.224:30301"] #p2p-host="0.0.0.0" p2p-port=30306 max-peers=42 host-allowlist=["*"] logging="ALL" min-gas-price=0 revert-reason-enabled=true rpc-http-enabled=true rpc-http-host="0.0.0.0" rpc-http-port=22006 rpc-http-cors-origins=["*"] rpc-http-api=["ETH", "NET", "WEB3", "QBFT", "DEBUG", "TRACE", "TXPOOL"] rpc-ws-host="0.0.0.0" rpc-ws-enabled=true rpc-ws-port=32006 rpc-ws-api=["ETH", "NET", "WEB3", "QBFT", "DEBUG", "TRACE", "TXPOOL"] # Chain genesis-file="genesis.json" # Path to the custom genesis file ``` {% endcode %} {% endtab %} {% endtabs %}
Configuration with static-nodes.json Sync your node using static-nodes Uncomment in the configuration file the following line : {% code overflow="wrap" %} ```toml static-nodes-file="data/static-nodes.json" ``` {% endcode %} ```bash cd network/node1/data ``` Create a `static-nodes.json` file with the following content : {% code title="For Testnet" overflow="wrap" %} ```json [ "enode://23b6a539306cc1f3a61230e3253cebf9b6cad37fa045954fe27cef265ab232329456c786d16d6c132eaf957b75f5e87629ec7e6a7aa271e9c346b2cde2e0a4d0@95.111.219.167:30301" ] ``` {% endcode %} {% code title="For Mainnet" overflow="wrap" %} ```json [ "enode://39f394a6c9bec694d2c7dc5b1c5b20611fbfb9212a5f75c28febdff92eb290ea7ec1c5a3873d7e14a32ec3bc7072f52ef4dfbf9c7387c8315b9d3a5b48e981df@94.237.66.224:30301" ] ``` {% endcode %}
### Start Node ```bash besu --config-file=config.toml ``` ### Run as a Service
Simple service ``` sudo adduser --system --no-create-home --group besu sudo chown -R besu:besu /path/to/NodeDirectory ``` Create a service file for each node in `/etc/systemd/system/.` ```bash sudo nano /etc/systemd/system/besu.service ``` ```bash [Unit] Description=Hyperledger Besu Ethereum Node After=network.target [Service] Type=simple User=besu Group=besu WorkingDirectory=/path/to/Node1 ExecStart=/path/to/besu-24.1.1/bin/besu --config-file /path/to/Node1/config.toml KillMode=process KillSignal=SIGINT TimeoutStopSec=90 Restart=on-failure RestartSec=100 [Install] WantedBy=multi-user.target ``` Reload the systemd daemon: ```bash sudo systemctl daemon-reload ``` **Start and enable the service**: ```bash sudo systemctl enable besu sudo systemctl start besu sudo systemctl status besu ``` Verify the status service: ```bash journalctl -fu besu sudo journalctl -f -u besu.service -o cat sudo journalctl -f -u besu.service -o cat | ccze -A ``` If the ports are already used on the local machine. Check: ```bash sudo netstat -tulpn | grep LISTEN ``` Stop them if you can: ```bash kill or kill -9 (to force) ``` And restart the service: ```bash sudo systemctl restart besu ```
Confirm the node is running We can call the JSON-RPC API methods to confirm the node is running. [`eth_syncing`](https://besu.hyperledger.org/public-networks/reference/api#eth_syncing) return the synchronization status : returns the starting, current, and highest block, or `false` if not synchronizing (or if the head of the chain has been reached). ```bash curl -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":51}' http://127.0.0.1:22005 ```
