Secure Donation Project based on truffle /metamask/ganache Your guide to build a project donation based on blockchain in order to ensure the traceability and the security of your money donation. Steps : Step 1:Setup your IDE coding in my case i choose VS code 1-I install the extension of truffle on VS Code .and I learn the basics of truffle thanks to the official site : https://trufflesuite.com/docs/truffle/ by the way truffle is just a development environment to code and compile your smart contract and is testing framework for blockchains using the ethereum virtual machine .So let’s take the first step : I created a folder named Nour project using this command : mkdir NourProject and also inside it i created 2 other folders :mkdir frontend and mkdir Blockchain Step2:Start with truffle so now let’s create our truffle project inside Nourproject/Blockchain thanks to the command truffle init Now let’s create our smart contract named Donation.sol in Nourproject/Blockchain/contracts and in direction Nourproject/Blockchain/migration/Donation.js fo deploying later your smart contract on ganache we will use this fil!e .js So our smart Contract looks like: //SPDX-License-Identifier:MIT pragma solidity ^0.8.0; //so contract Donation{ //struct :define your type Donor //inside struct you can grouping your different information that you wanna track it struct Donor{ //uint (only integer without minus) uint id ;//id of donor string name;// the name of donor uint256 amount;// the amount of donor address sender_address;//Donprs wallet address } uint256 id=0; //Mapping is Mapping is a reference type as arrays and structs as dictionnary in python is composed essentially by key =>value mapping(uint=>Donor)public sender; //function to add another donor to take a place //payble is function its role to recieve ETH from donors in oder to store //donors data and the amount paid function addDonor(string memory name)public payable { id+=1; sender[id]=Donor(id,name,msg.value,msg.sender); } So now let’s how to complelete the donation.js in migration so after coding our smart contract we have install ganache thanks to this link: https://trufflesuite.com/ganache/ so now let’s compile the smart contract thans to this command truffle compile before we deploy it into ganache we have to add the project into ganache now let’s relate ganache to truffle test so let’s deploy it into the ganache (local blockchain test ): truffle migrate Step3 :Frontend part this part based on html /css/js So in this part just we use the basic tools of html/css/js as u see here in the image bellow : so let’s understand some buttons function as the button connect this button it’s main function is to extract address account from metamask so the steps that you should follow it in this part just build a simple button thanks to bootstrap https://getbootstrap.com/docs/5.2/getting-started/introduction/ and create a simple squelette of form and add some animation thanks to css so let’s add the script of web3.js to let our website worked on blockchain browser thanks to this script <script src="https://cdn.jsdelivr.net/npm/web3@latest/dist/web3.min.js"></script> so enable it by writing this piece of code //Enable Web3 async function loadWeb3(){ if(window.ethereum) { window.web3 = new Web3(window.ethereum); } } and then load smart contract from truffle thanks to it’s ABI and it’s address : you can find the ABI in build file it will create automatic when you built your contract so in my case my ABI is located in the direction of build /Donation.json so My ABI : "abi": [ { "inputs": [ { "internalType": "uint256", "name": "", "type": "uint256" } ], "name": "sender", "outputs": [ { "internalType": "uint256", "name": "id", "type": "uint256" }, { "internalType": "string", "name": "name", "type": "string" }, { "internalType": "uint256", "name": "amount", "type": "uint256" }, { "internalType": "address", "name": "sender_address", "type": "address" } ], "stateMutability": "view", "type": "function" }, { "inputs": [ { "internalType": "string", "name": "name", "type": "string" } ], "name": "addDonor", "outputs": [], "stateMutability": "payable", "type": "function" } ], So the address is the same of the contract address : so after loading the smart contract thanks to it’s ABI and address you can read data from and load all of it’s function by some code in js and then connect to the metamask wallet and get the address of the account after just donate by the button donate all of :this detail is written in code js you can say it in code js in the code file wish that document is helpful So as you see after donate to ether thanks for some fake ethers in the metamask wallet which is take it fro the ganache balances with simple steps just open metmask extension>settings >add network>then add the url rpc of your ganache and in the id chain write 1337 after passing the transaction another block added in the ganache so that’s all wish this documentation was helpful to you to understand the code how it running

GROUP INFORMATION: Number Member names UFID 1 Niraja Ganpule 17451951 2 Harshal Patil 55528581 Project Description We have successfully implemented the Distributed Bitcoin protocol and displayed the bitcoin transaction details on a webpage using the Phoenix framework. We have tested it for 100 nodes. The concepts implemented are: 1. Distributed Architecture for nodes Each node is a GenServer that contains the state in the format: a. Blockchain Each node must have the same copy of the blockchain at all times. If there is any change in the blockchain made by any node, it must be advertised to all other nodes and all nodes must synchronize to this b. Wallet Each node has its own wallet with the Bitcoin address, private key and balance. In this design, all the nodes can participate in transactions and also mine blocks. 2. Implemented a simulation with at least 100 participants in which coins get mined and transacted. 3. Implemented a web interface using the Phoenix that allows access to the ongoing simulation using a web browser The Phoenix webpage dynamically displays the following a. Transactions from sender to receiver and the amount sent as and when the transaction happens b. Once all the transactions are mined by a node and a block is added to the blockchain, the balance of every node is calculated by traversing the blockchain using the wallet address of node and displayed c. A graph of balance of each node versus the nodes id is plotted to show variation of balance between nodes after transactions are mined 4. Mining/transacting scenarios include random selection of sender and receiver nodes. Other features are : . Bitcoin transaction . Bitcoin wallet . Bitcoin mining or Proof of work . Creating the bitcoin address as done by the real Bitcoin System based on steps described here https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses . Creating a blockchain with a genesis block, adding a new block to the blockchain after a node mines pending transactions,checking authenticity of the blockchain and maintaining synchronization between successive blocks. . Signing transactions with private key of the wallet and verifying them with public key at any point for security and authentication . Finding the balance of a user wallet by the same user or any other user using only the current blockchain as input. Here, computations are made based on transactions recorded in every block in the blockchain to find the balance of a particular user. Execution Instructions To compile and run a demonstration of the built-in functionalities in the application : In the main folder bitcoinmine, on the commandline, run the command : mix phx.server Go to your favorite browser and type URL http://localhost:4000 To change number of nodes, in lib/start.ex in the main function, change the value of numnodes variable to whatever you want to set it to To change number of transactions per block, in lib/start.ex in the handle/1 function, change the value of numtransact variable to whatever you want to set it to

Laws To Stop Loss A look at cryptocurrency from a legal standpoint A popularity surge in Bitcoins and cryptocurrency, in general, has caught the interest of many first time retail investors. While the industry is highly dynamic in its legality around the world, here are some legal challenges retail investors must be aware of. A decentralised approach Cryptocurrency lacks a physical form and is not controlled by a central authority. This very independent approach based on which the whole cryptocurrency system works can cause legal and jurisdictional implications. The value associated with cryptocurrency is highly volatile but is ascribed to by owners and investors, just like traditional currency. However, there is no central authority that legitimises the value of the digital currency, should complications with ownership and transactions arise. In such instances, investors are left with little to no legal avenue. The blockchain technology that makes the cryptocurrency ecosystem uniquely trust-less also poses major complications when it comes to jurisdiction. The blockchain is a ledger that holds a record of all transactions in a digital format. It has no physical copy that can be pinpointed to a certain location. Servers that make entries on these ledgers are scattered around the world and fall under various jurisdictions that may have a conflicting legal framework. This cross-border framework makes it extremely difficult to determine the correct jurisdiction for blockchain disputes. Smart contracts Smart contracts are self-executing contracts that work without the interference of an external party on a blockchain network. These can be thought of as terms and conditions in a digital format that all parties involved have agreed upon. Smart contracts can automatically fulfil transactions when specified conditions are met. These contracts are independent of the legal framework of the society at large, thus raising a question of their legal validity. In case of disputes, the validity of smart contracts may get challenged. Cryptocurrency taxations The most integral decision in holding a cryptocurrency for any investor must involve its tax implications, as it directly affects the profits one hopes to achieve. Some countries such as the U.S. consider cryptocurrency holdings as assets and not currency, making the holdings eligible for capital gains tax on any profit realized by cryptocurrency. Things get even more complicated when cryptocurrency is purchased on foreign exchanges and a tax system of multiple countries is involved. Such purchases might be subject to additional reporting measures at taxation. Given the discouraging stand, some countries take on cryptocurrency and the constantly evolving rules around them, investors must practice caution and seek the expert advice of tax professionals. Money laundering The anonymity that the blockchain offers can be abused to commit fraud, money laundering and other financial scams. Cryptocurrencies have found their way on the dark market as well where they are used to buy and sell contraband. Systems also hold the potential to be hacked putting the holdings at risk of theft. Investors may find themselves a victim to these frauds. There is a lack of standard practice in case of such misfortune along with very little support from the central governing authority. Existing data laws may not suffice when it comes to financial frauds and data thefts from cryptocurrency networks. This is why platforms such as MARS constantly upgrade their wallets to ensure improved security measures. These challenges become even more pronounced because no intermediary or authority has the exclusive jurisdiction to settle disputes. It becomes highly imperative that investors mindfully acknowledge the risks they are associating themselves with before they begin to invest in any cryptocurrency.
