Updates on development and test-net2:

Wallet
Add Stealth addresses (used for better obfuscation when using RingCT);
Add view key (view transactions of a given account) and spend key (sign a transaction of a given account);
Outputs referencing inputs to the new transaction;
Add an extra field for transactions. (Replaces messages as separate service);
Fix RPC as JSON structure has changed;
Test end-2-end;
Remove and clean-up code.

Node
Fix RPC and MQTT, ( JSON structure has updated);

High effort tasks
1. Add coinbase transaction for rewarding nodes (according to the distribution and validation life-cycle);
2. Crude zk-PoS implementation.

Medium
1. Test end-2-end.

Low
1. Validate Multilayered Linkable Spontaneous Anonymous Group Signatures (MLSAG), including checking that inputs are referenced from the blockchain;
2. Merkle tree update (changes due to RingCT);
3. Mempool validation and verification for double spends.

With that being said, we're a couple of weeks out from completing the above then test-net2 can be released.
