Enclave is now The Interfold.
Encrypted Execution Environments

Shared results from private inputs.

The Interfold is an open-source protocol for confidential coordination. Independent parties encrypt their inputs, a committee of ciphernodes runs the computation, and only the verified output is decrypted.

DKG

Key generation. The committee runs DKG and makes one shared public key.

Each path starts with a short overview and continues to step-by-step procedures.

Learn

What an E3 is, how the architecture fits together, and the cryptography that protects the inputs.

ConceptsBuild

Install the CLI, make a project from the template, and write an E3 program with its contracts and client.

DevelopersRun a ciphernode

Set up a node, bond FOLD, get tickets, and serve on committees. Upgrade, migrate, and exit safely.

OperatorsReference

CLI commands, node configuration, contract addresses, and a glossary of protocol terms.

How it works
One E3, from request to result

The Interfold contract records each E3 as it moves through its stages. Ciphernodes act at each stage and publish proofs on-chain.

  1. RequestedA requester pays the fee and asks for an E3.
  2. CommitteeFinalizedSortition selects a committee of ciphernodes.
  3. KeyPublishedThe committee runs DKG and publishes one public key.
  4. CiphertextReadyThe program runs over the encrypted inputs. The encrypted output goes on-chain.
  5. CompleteT + 1 key shares decrypt the output, and a proof confirms it.
Committees
Security comes from the committee

No single ciphernode can decrypt. The protocol supports three committee sizes. Decryption needs T + 1 key shares.

3
minimum
N = 3, T = 1. The smallest committee.
9
micro
N = 9, T = 4.
19
small
N = 19, T = 9. Higher assurance.
Quick start
A working E3 in four commands

The template starts a local chain, local ciphernodes, the servers, and a web client. See the Quick Start for prerequisites.
