Initial mempool sync may take a lot of time

> All the above is strongly suggesting to me that the `rpc.sync()` call on [this line](https://github.com/romanz/electrs/blob/d84d7d672c456fceac55e8143d0775ed10684991/src/server.rs#L93-L94) is blocking for too long, probably because the `mempool.sync()` call on [this line](https://github.com/romanz/electrs/blob/d84d7d672c456fceac55e8143d0775ed10684991/src/tracker.rs#L77) is...

Feature: try out speedb (instead of rocksdb)

elements: add rangeproof nonce derivation

2

Following https://github.com/trezor/trezor-firmware/pull/317#issuecomment-585648571, we would like to allow confidential transaction output unblinding on the host by adding a new API for Elements rangeproof nonce derivation (see [device tests](https://github.com/romanz/trezor-firmware/blob/d3192674d229709be8c774c633bdae9adf899bb3/tests/device_tests/test_msg_signtx_elements.py#L861-L881) at [elements/wip branch](https://github.com/romanz/trezor-firmware/commits/elements/wip)).

elements: derive confidential addresses using SLIP-0077

Following #66 and #398, it would allow receiving confidential transactions to addresses generated on the devices. Blinding, unblinding and signing will be added in separate PRs.

elements: support explicit transaction signing

2

Implements initial support for [Elements](https://elementsproject.org/)' transaction signatures (following #66). Most of the code is similar to Bitcoin's, but there are a few deviations: - amount serialization is different (to support...

core/secp256k1_zkp: add blinding and rangeproof API

Allows rangeproof generation and rewinding, surjection proof generaion and Pedersen commitments' balancing on the device. Notes to reviewers: - The current code requires significant stack size increase (to ~40kB), so...

According to https://github.com/satoshilabs/slips/blob/master/slip-0044.md, `coin_type` should be 0 for mainnet & 1 for testnet.
