Hi I am a software engineer with over 16 years of experience, including C++ core systems, PoW consensus code, wallet builds, and blockchain fork work. This project is the kind where Dash-specific details matter, especially preserving ChainLocks, InstantSend, quorum/masternode behavior, governance, and mining economics while changing supply, rewards, collateral, block timing, and genesis/network parameters. I prefer a fixed-price structure for the defined scope, with milestones for parameter/fork changes, fee smoothing or burning logic, testnet validation, genesis creation, wallet builds, and explorer setup. If the scope expands after review of the exact Dash Core version and deployment targets, we can convert part of the work to hourly. Relevant fork and core-chain work cannot be shared publicly, but I can show examples/code references privately or under NDA as requested. I can start shortly after scope confirmation and allocate about 30-35 hours per week. A few questions: which Dash Core branch/version do you want to fork from, do you already have exact reward schedule and collateral numbers, and should the explorer be based on an existing Dash-compatible stack or built as a clean deployment around your new chain? Please contact me to discuss details.

Hi, I will fork the Dash Core codebase into a new L1 chain with your 8 billion coin supply, modified block time and reward schedule, and the EIP-1559 style fee-burning mechanism, while keeping ChainLocks, InstantSend, and the two-tier masternode governance fully intact. On a previous Dash fork, isolating the collateral and reward parameters into a clean config layer made future adjustments possible without touching consensus logic. I will structure yours the same way. Questions: 1) For the fee-smoothing mechanism, do you want a pure burn model or a partial burn with a portion redirected to masternodes? 2) Do you already have a preferred PoW algorithm for the fork, or will it stay with X11? Looking forward to discussing further. Best regards, Kamran

Hello, Thank you for the detailed project description. I want to be transparent regarding my experience. I have extensive C++ development experience and have worked with distributed systems, networking, embedded software, and blockchain-related concepts, including PoW consensus, node communication, wallets, and protocol implementation. However, **I have not previously led a production Dash Core hard fork**, so I cannot honestly provide GitHub links or claim contributions to Dash-based coins. **Availability** * Start: Immediately * Weekly commitment: 30–40 hours (flexible) **Fee Structure** * I prefer **hourly** billing for projects of this complexity, although I'm open to agreeing on fixed-price milestones after reviewing the detailed specifications. **Questions** 1. Which Dash Core version will be the fork baseline? 2. Are the economic changes (fee smoothing/burning) already specified, or should they be designed collaboratively? 3. Will you require testnet, CI/CD, and automated regression testing as part of the deliverables? 4. Is the block explorer expected to be a customized Insight/electrum-style explorer, or do you have another preference? If prior production Dash fork experience is a strict requirement, I may not be the right fit. If you're open to a senior C++ engineer with strong blockchain fundamentals who can contribute under that constraint, I'd be glad to discuss the project further.

This looks like a great fit, We will fork Dash Core, adjust block time, reward schedule, and supply to 8 billion, then preserve ChainLocks, InstantSend, and the masternode governance layer intact. For the fee-smoothing mechanism, we will implement a base fee adjustment per block (similar to EIP-1559) directly in the consensus rules. Excess fees above the target will be burned, which stabilizes miner revenue without breaking the existing masternode reward split logic. A couple of quick things to confirm: 1) Do you have the exact block time and reward schedule parameters finalized, or do you need us to model emission curves first? 2) For the block explorer and wallet, are you open to adapting Dash Insight and the Dash Core Qt wallet, or do you need a web wallet built separately? Looking forward to potentially working together. Thanks, Faizan

I'd like to ask: Have you already finalized the new consensus and economic parameters, including block timing, reward schedule, and fee-burning model? Will the initial scope include wallet branding, explorer deployment, seed nodes, and mining infrastructure, or should these be delivered as separate milestones? I understand you're looking for an experienced C++ blockchain developer to hard fork the Dash Core codebase while preserving ChainLocks, InstantSend, and the masternode architecture, alongside implementing new consensus parameters, fee mechanics, genesis block generation, wallet software, and a production-ready L1 blockchain. Here's how I'll approach it: Fork and customize the Dash Core codebase. Update consensus rules, rewards, supply, and masternode collateral. Implement the new fee-burning/smoothing mechanism. Generate a secure genesis block and launch configuration. Deploy wallets, block explorer, seed nodes, and perform extensive testing before mainnet. With 10+ years of experience, my team develops blockchain infrastructure, Layer-1 networks, consensus protocols, C++ systems, and enterprise-grade distributed applications with a strong focus on security and performance. I prefer a fixed-price engagement and can communicate in real time according to your time zone. I can also provide an architecture review and implementation roadmap within 12 hours of starting.

Hello Dashtron team, I find your project to fork Dash Core into a new Layer-1 blockchain very compelling and believe I can contribute effectively. I have extensive experience working directly with Dash Core, having contributed to two Dash forks where I implemented custom block parameters, adjusted masternode collateral, and preserved ChainLocks and InstantSend functionalities. My expertise includes deep C++14/17 development, PoW consensus mechanisms, and integrating fee-burning models akin to EIP-1559 to stabilize mining rewards. In my opinion, the key to a successful fork lies in meticulous preservation of Dash’s unique governance and security features while ensuring the economic changes are seamlessly integrated and thoroughly tested. Potential challenges include maintaining consensus stability during parameter shifts and ensuring compatibility of the new fee mechanism with existing masternode incentives. If you wish, I can prepare a prototype fork demonstrating core parameter changes and ChainLocks integration promptly. To clarify scope details: 1. What specific block time and reward schedule parameters do you envision? 2. Are there preferred technologies or frameworks for the new block explorer and wallet? 3. How do you plan to handle network bootstrapping and initial masternode distribution? I am available to start immediately and can work on a fixed-price or hourly basis as you prefer. Let’s chat now to discuss next steps. Thank you for considering my bid. Matt
