Mobile and Utreexo

Mobile and Utreexo

Dinero v8 supports a local-validation mobile path using Utreexo-style proof data.

The main distinction:

• Local validating Utreexo node: verifies headers, chainwork, block/proof data, and accumulator state locally.
• Remote RPC wallet: asks a remote server for wallet/chain state and treats that server as the authority.

These are different trust models and should not be described as the same product.

Useful Sync Signals

When debugging mobile local-validation sync, capture:

• validated local block height
• best header height
• connected bridge peers
• whether getdata for Utreexo blocks is sent
• whether utxoblk messages are received
• whether blocks connect after receipt
• whether the accumulator/forest advances
• whether snapshot/bootstrap restore activated

Bridge Nodes

Bridge/proof-serving nodes are full nodes that can serve Utreexo block/proof data to local-validating clients. For mobile reliability, clients should have more than one healthy bridge peer.
