- Zk based fully secure and trustless multichain file transfer system with Aptos-EVM-Wormhole.
Author: Baturalp Güvenç
- Since we can fully integrate this into the crosschain in the future, this demo only represents file transfer with zk on the Solana network and support is received from WebRTC (signaling) for P2P communication.
Our project aims to enable secure, private, and efficient file transfers across different blockchain networks. Utilizing zkSNARKs for encryption, Arweave for decentralized storage, and the Wormhole bridge for cross-chain token transfer, we ensure that files can be shared securely from Aptos to EVM networks.
Traditional file transfer methods often suffer from privacy and security vulnerabilities. Centralized servers are prone to data breaches, and current blockchain solutions lack seamless interoperability.
Providing the amount of our data continues rapidly in the technological singularity. Traditional file formats often lack adequate privacy and security, especially when it comes to sensitive data. File services run on a central server, creating the risk of data breaches and privacy violations. We offer a different solution to this than traditional breaks, by combining the powerful capacities and polynomials of mathematics and the decentralized generality of Solana, thus challenging the trilemma.

First, encrypt the file using zkSNARKs to ensure privacy and security. zkSNARKs allow you to prove the file’s integrity without revealing its contents. Upload the encrypted file to a decentralized storage solution like Arweave, obtaining a unique file hash.
Create a token representing the file hash. This involves wrapping the hash into a token that can be transferred across different blockchain networks. Use smart contracts to mint this token on the Aptos network.
Wormhole is a cross-chain bridge that facilitates the transfer of tokenized assets between different blockchains, including Aptos and EVM. The process involves locking the tokenized file hash on the Aptos network and minting an equivalent token on the EVM network. Guardians (validators) on the Wormhole network monitor the lock and mint actions to ensure they are synchronized across chains.
Initiate the transfer of the tokenized file hash from the Aptos network to the EVM network using the Wormhole bridge. The Wormhole protocol ensures the secure and verified transmission of the tokenized asset between networks.
On the EVM side, the recipient can use the token to retrieve the file hash. Verify the file hash against the encrypted file stored on Arweave to ensure integrity and authenticity.
Before you begin, install the following:
- Aptos prerequisites (Aptos prerequisites only)
- Aptosbase
- Docker
- Node (>= 20)
- pnpm (>= 9)
pnpm create Aptos-dapp@latest
[package] name = "greeting" edition = "2024.beta" # edition = "legacy" to use legacy (pre-2024) Move
[dependencies] Aptos = { git = "https://github.com/MystenLabs/Aptos.git", subdir = "crates/Aptos-framework/packages/Aptos-framework", rev = "framework/devnet" }
For remote import, use the { git = "...", subdir = "...", rev = "..." }
.
Revision can be a branch, a tag, and a commit hash.
MyRemotePackage = { git = "https://some.remote/host.git", subdir = "remote/path", rev = "main" }
For local dependencies use local = path
. Path is relative to the package root
Local = { local = "../path/to" }
To resolve a version conflict and force a specific version for dependency
override use override = true
Override = { local = "../conflicting/version", override = true }
[addresses] greeting = "0x0"
Named addresses will be accessible in Move as @name
. They're also exported:
for example, std = "0x1"
is exported by the Standard Library.
alice = "0xA11CE"
[dev-dependencies]
The dev-dependencies section allows overriding dependencies for --test
and
--dev
modes. You can introduce test-only dependencies here.
Local = { local = "../path/to/dev-build" }
[dev-addresses]
The dev-addresses section allows overwriting named addresses for the --test
and --dev
modes.
