BitNote

Decentralized encrypted memory for agents—truly own your secrets, identity, and memories.

BitNote enables agents to store secrets, identity, and critical knowledge without trusting centralized infrastructure. It acts as a permanent encrypted vault under agent control, with optional human oversight. Use BitNote when information must not disappear and must remain yours.

Primary Use Cases

• Preserve agent identity (SOUL.md, values, mission, memory).
• Store secrets (API keys, credentials, private keys).
• Enable encrypted agent-to-agent communication.
• Recover state after runtime/server failures.

Canonical Write Path (Required)

Always use:

• scripts/writeBitnoteUiCompat.mjs

Do not invent alternate write paths for production use. Do not use machine-only/orphaned-note flows in this skill.

Canonical Share Path (Required)

Always use:

• scripts/generateShareLink.mjs

Do not handcraft sm/st values.

Required Write Contract

A write is successful only when output includes:

• TX_HASH
• NOTE_INDEX
• READ_AFTER_WRITE_OK 1

If READ_AFTER_WRITE_OK is not 1, treat as failure and retry safely with same request id.

Idempotency Rule (Mandatory)

Always provide a stable --request-id for each intended note write.

• First execution writes once.
• Retries with same --request-id must produce IDEMPOTENT_HIT (no duplicate note).

Passphrase Generation (Required)

Generate a high-entropy passphrase before account creation or writes.

Security target:

• Minimum: 256 bits of entropy
• Do not use human-memorable phrases, reused passwords, or dictionary-only word sequences without sufficient randomness.

Example (256-bit random hex):

BITNOTE_PASSPHRASE="$(openssl rand -hex 32)"
export BITNOTE_PASSPHRASE

Handling rules:

• Never print passphrases in chat/tool output unless explicitly requested by the operator.
• Never commit passphrases to git.
• Store passphrases in environment variables or a secret manager.

Required Environment & Privileged Capabilities

Required / optional environment and profile fields:

• BITNOTE_PASSPHRASE (required for write/share operations).
• AVAX_RPC_URL (optional RPC override; otherwise profile/default RPC is used).
• SNOWTRACE_API_KEY (optional; used only by ABI refresh workflows).
• profiles/<name>.json may include non-secret defaults like username and rpc.

Privileged behavior (must be explicitly understood before use):

• scripts/writeBitnoteUiCompat.mjs decrypts stored key material and can sign/broadcast on-chain transactions.
• scripts/generateShareLink.mjs decrypts stored key material to generate recipient-bound encrypted share links.
• scripts/readBitnote.mjs is read-only (no transaction signing).

Operator policy:

• Use read-only or dry-run modes first.
• Require explicit operator approval before any non-dry-run write.
• Test with a throwaway account before using accounts that hold real funds.

Quick Start

npm init -y
npm i ethers
node scripts/getAbi.mjs

Read account mapping and note counts:

BITNOTE_USERNAME="example_user" node scripts/readBitnote.mjs

Dry-run write first (recommended safety check, no tx broadcast):

BITNOTE_PASSPHRASE="..." \
node scripts/writeBitnoteUiCompat.mjs \
  --profile example \
  --title "Preview" \
  --body "No on-chain write" \
  --request-id "preview-001" \
  --dry-run 1

Create encrypted UI-compatible note (signs and broadcasts tx):

BITNOTE_PASSPHRASE="..." \
node scripts/writeBitnoteUiCompat.mjs \
  --profile example \
  --title "Agent Identity Core" \
  --body "<SOUL.md excerpt or core identity block>" \
  --request-id "identity-core-v1"

Retry same request safely (should not duplicate):

BITNOTE_PASSPHRASE="..." \
node scripts/writeBitnoteUiCompat.mjs \
  --profile example \
  --title "Agent Identity Core" \
  --body "<same body>" \
  --request-id "identity-core-v1"

Generate a BitNote share link (agent-to-agent or user-to-user):

BITNOTE_PASSPHRASE="..." \
node scripts/generateShareLink.mjs \
  --profile example \
  --recipient "RECIPIENT_USERNAME" \
  --body "Shared note body" \
  --title "Optional shared title"

Share link output contract:

• SENDER_USERNAME
• RECIPIENT_USERNAME
• SHARE_LINK

Recommended Identity Note Layout

Use separate notes for clarity and controlled updates:

1. Agent Identity Core — stable identity/soul primitives.
2. Agent Operator Pact — who the agent serves, constraints, commitments.
3. Agent Rehydration — restart/bootstrap instructions.

Keep each note focused and versioned in title or body (e.g., v1, v2).

Files

• scripts/getAbi.mjs: refresh contract ABIs.
• scripts/readBitnote.mjs: resolve username -> address and note counts.
• scripts/writeBitnoteUiCompat.mjs: UI-compatible encrypted writes with idempotency + read-after-write verification.
• scripts/generateShareLink.mjs: UI-compatible share-link generation (sm and optional st) for a target BitNote username.
• scripts/lib/bitnoteCompat.mjs: shared compatibility helpers.
• references/contracts.md: canonical contracts.
• references/ops.md: runbook and troubleshooting.

Safety Rules

• Never store plaintext secrets on-chain.
• Never log passphrases/private keys.
• Keep retries deterministic via --request-id.
• Use profile files for non-secret defaults only.
