Traceva Drop

Encrypted File Storage and Access Control

File Encryption Standards and zkProof-Based Access Control

Traceva Drop employs advanced encryption standards (AES-256, asymmetric cryptography) combined with zk-based cryptographic proofs for secure, decentralized file storage. Access to stored files is strictly controlled through cryptographic verifications, ensuring only authorized users can retrieve specific data.

import { create } from 'ipfs-http-client'
const ipfs = create({ url:'https://ipfs.infura.io:5001/api/v0' })
const { cid } = await ipfs.add(new Blob(['hello traceva']))

Mechanisms for Time-locking, Self-destruction, and Single-use Access

Traceva Drop allows users to define sophisticated file accessibility conditions, including time-locking (restricting access until a predefined time), automatic file self-destruction upon access or expiry, and single-use retrievals. These granular controls significantly enhance file privacy, security, and confidentiality.

Decentralized Storage Integration (IPFS, Filecoin, Arweave)

Files managed via Traceva Drop are securely stored using decentralized storage networks, including IPFS, Filecoin, and Arweave. Leveraging these robust, censorship-resistant platforms ensures reliable, permanent, and private file storage.

import Arweave from 'arweave'
const arweave = Arweave.init({ host:'arweave.net',protocol:'https',port:443 })
const tx = await arweave.createTransaction({ data: Buffer.from('secret') }, key)
tx.addTag('Content-Type','text/plain'); await arweave.transactions.sign(tx, key)
await arweave.transactions.post(tx)

Use Cases: Confidential Documents, Medical Records, DAO Proposals

Traceva Drop supports storage and distribution of highly confidential documents such as medical records, DAO governance proposals, legal files, and sensitive corporate information, delivering privacy-compliant, secure, and tamper-proof access solutions.
