Partial Endorser Block Certification via Merkle Trees

This proposal adds merkle tree structures to EBs, enabling partial transaction set certification when full EB propagation is delayed. We trade larger EB size for improved resilience under adverse network conditions.

Motivation

Current Leios requires RB producers to resolve all EB transaction references before proceeding. When network conditions prevent full EB propagation within $\Delta_{RB}$, producers face unacceptable choices: violate timing assumptions, create forks, or include invalid transactions.

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
