Hosted PAB setup

This document describes how to prepare hosted PAB deployment from scratch that can operate on Alonzo purple testnet.

The following required to be run on host machine to use PAB with contracts in hosted scenario on testnet (for 2020-11-05 PAB Release):

• Cardano node connected to Alonzo testnet
• cardano wallet connected to node
• chain-index connected to node
• PAB executable connected to node, cardano-wallet and chain-index

Note: we are using somewhat more involved setup with a bit custom docker compose, and wallet and chain-index being built from sources, but there is ready to go node+wallet docker solution available

Parity-Signer Secure Key Storage Proposal

Here I conclude the recent research and discussions with the storage of the seed/private key in parity-signer.

Current Implementation

Currently, we require a user to input a pin code for encrypting the seed, and then put the encrypted seed together with other account data into a secure store. The secure store then uses the native KeysStore or KeyChain to store the encrypted account data.

Possible improvement
