This repo contains a complete developer preview of a baseline contract implementation: a single-signer [`Quantumroot Schnorr+LM-OTS Vault](https://ide.bitauth.com/import-gist/60e779f718515b83fb80706e078acdb3).\n\nThe `Quantumroot Schnorr+LM-OTS Vault` is fully implemented in CashAssembly, including all private key derivation, address generation, and the quantum signing scheme. Wallets can compile transactions directly from the template using any HD Key – no template-specific code.\n\nFor more information, see the full Quantumroot post:\n\n[Quantumroot: Quantum-Secure Vaults for Bitcoin Cash (bitjson.com) \u0026rarr;](https://blog.bitjson.com/quantumroot)\n\n---\n\n## Example Transactions\n\nFor ease of review, this repo exports two example transactions, `Pre-Quantum Aggregation` and `Post-Quantum Aggregation`.\n\n- The `Pre-Quantum Aggregation` transaction demonstrates the most privacy-preserving aggregation – Introspection-based **cross-input aggregation** – where all inputs spend UTXOs from the same address, i.e. no leaks of other wallet addresses.\n- The `Post-Quantum Aggregation` transaction demonstrates both cross-input aggregation and a more specialized aggregation – CashToken-based **cross-address aggregation** – where UTXOs from multiple addresses are spent using the same quantum signature. (Strong privacy can still be achieved before and after such transactions, e.g. with ZKP covenants.)\n\n### Pre-Quantum Aggregation\n\n`Pre-Quantum Aggregation` spends 20 inputs:\n\n- Input 0: a schnorr spend of Address A\n- Input 1 through 19: introspection spends of Address A\n\n### Post-Quantum Aggregation\n\n`Post-Quantum Aggregation` spends 8 inputs. `Address Q` is a\n\n- Input 0: includes the authorizing CashToken and quantum spend of Address Q\n- Input 1: a token spend of Address A\n- Input 2: a token spend of Address B\n- Inputs 3 and 4: introspection spends of Address A\n- Inputs 5 and 6: introspection spends of Address B\n- Input 7: introspection spend of Address Q\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbitjson%2Fquantumroot","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbitjson%2Fquantumroot","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbitjson%2Fquantumroot/lists"}
