# CAPPZ Replicator

> Keep copies of business documents up to date. Replicator reconciles missing changes over a peer path; its live wallet dashboard uses account-linked records.

Source: https://cappz.ai/replicator

Keep every copy of a business document up to date. Replicator finds missing changes and reconciles wallet copies. Message sync is peer-path. Relay remains optional for discovery and offline pickup. Sign-in/admin may still be hosted. This live view uses account-linked records; for a public, same-device sample, try the two-copy demo. Every figure here is replayed from replication records — nothing is sample data.

LIVE PATTERN · CAPPZ REPLICATOR

The middleware hub just became optional. Parties synchronize directly. Contracts, applications, data, and shared multi-master state bilaterally replicated, peer to peer.

- 1 WHISPER (UDP BEACON · PAIRING CODE)
- 2 PUBLISH HEADERS
- 3 DISCOVER MISSING STATE
- 4 SYNCOFFERED ↔ SYNCREQUESTED
- 5 ENCRYPTED A2A BLOCKS
- 6 HASHES VERIFIED
- 7 HEADS CONVERGED
- 8 HIGH QOS CHECKSUM DELIVERY · HASH-PRINT RECEIPT

REAL-WORLD DEMO

Two wallet copies, two tabs. Create an ISO 20022 payment in one and watch it verify and converge in the other.

## Whisper to find. Connect to move.

Discovery whispers, transfer connects. Peers find each other by UDP beacon, relay rendezvous, pairing code or wallet breadcrumbs, then move the same signed, checksummed frames over TCP, QUIC, WebRTC, a WebSocket bridge or a USB bundle. No host in the middle, no browser required.

- UDP beacon LAN multicast, signed, rate-limited. Announces heads only — never state.
- Relay rendezvous Optional meeting point across the internet. Carries no payload.
- Pairing code QR, typed, or spoken (sound-pairing). Short-lived, speakable.
- Wallet breadcrumbs Endpoints declared on-chain by TransportCapabilityDeclared.

- **Transport**
- **Runs on**
- **NAT**
- **Offline**
- TCP Bitcoin-style sessions: hello, inventory, headers-first, pull bodies.
- Standalone node
- Needs a reachable port
- LAN
- QUIC Reliable and encrypted over UDP. Same frames as TCP.
- Standalone node
- NAT-friendly (UDP)
- LAN
- WebRTC How a browser gets a peer socket.
- Browser
- Hole-punching
- LAN
- WebSocket bridge The browser rides the node’s TCP/QUIC sockets.
- Browser → local node
- Localhost only
- Yes
- USB bundle Signed file carried by hand. Same manifest-first protocol.
- Anywhere
- n/a
- Air-gap

A read-only XRPL connector watches validated ledger headers and checks anchoring proofs itself — no hosted verifier, and it never submits transactions.

Borrowed from Bitcoin: the peer pattern. Left behind: proof-of-work and global broadcast.

### My wallets

How safe each wallet is, and where its copies live. You control the dial.

No wallets yet — unlock your wallet to see yours.


### Escrow targets

Pick your drive once. After that the Replicator copies your wallets to it whenever it is available, and tells you when it does.

No escrow target yet.


### Escrow history

Every copy made, with its content hash. This log is yours.

Nothing escrowed yet.


### Farm load balance

0 node(s) · 0 delivered · all reachable copies converged

No copies have announced a head yet.


### Flow traffic routing

Per-flow state on the live ledger: offered → delivered → receipted → converged.

No flows recorded yet.


### Flow replay

0 of 0 events match. Step through a flow or export the slice.

Nothing matches those filters.


## How sync works

A copy that lacks records posts a sync request to its own in-queue. The source copy answers over an encrypted channel derived from both wallet keys; only hashes are recorded, never the data itself. Sign in to see your copies.
