Overview

SilentDragonLite (SDL) is a fork of Zecwallet lightwalletd, which is a fork of lightwalletd from the ECC.

It is a backend service that provides a bandwidth-efficient interface to the Hush blockchain for the SilentDragonLite cli.

Changes from upstream lightwalletd

This version of lightwalletd extends lightwalletd and:

  • Adds support for HUSH
  • Adds support for transparent addresses
  • Adds several new RPC calls for lightclients
  • Lots of perf improvements
    • Replaces SQLite with in-memory cache for Compact Blocks
    • Replace local Txstore, delegating Tx lookups to Zcashd
    • Remove the need for a separate ingestor

Running your own SDL lightwalletd

0. First, install Go >= 1.11.

1. Generate a TLS self-signed certificate

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

Answer the certificate questions to generate the self-signed certificate

2. You need to run a full node with the following options in HUSH3.conf

server=1
rpcuser=user
rpcpassword=password
rpcbind=127.0.0.1
txindex=1

3. Run the frontend:

You'll need to use the certificate generated from step 1

go run cmd/server/main.go -bind-addr 127.0.0.1:9069 -conf-file ~/.komodo/HUSH3/HUSH3.conf  -tls-cert cert.pem -tls-key key.pem

4. Point the zecwallet-cli to this server

./zecwallet-cli --server https://127.0.0.1:9069 --dangerous
