Alpha 1.3

1. FullNode performance improvements - Syncing up to the blockchain by importing all blocks is faster due to improvements in VDF verification speed and multithreading block verification. Also fixed a bug where the node may not sync if it restarts close to a tip.

2. VDF improvements - VDF verification and generation speed has increased and dependence on flint2 has been removed. We wish to thank Dr. William Hart (@wbhart) for dual licensing parts of his contributions in FLINT and Antic for inclusion in the Chia blockchain.

3. Implemented an RPC interface with JSON serialization for streamables - currently on port 8555 - and moved the ssh UI to use RPC.

4. Mongodb deprecated. Moved to SQLite for the blockchain database. This will require nodes to re-sync with the network. Luckily this is now faster.

5. Changed the displayed process names for harvester, farmer, fullnode, timelords, and VDFs to to chia_full node, chia_harvester, etc. Fixed a bug that could cause inadvertent shutdown of other processes like an ongoing plotting session when new chia services were started.

6. Added details on how to contribute in CONTRIBUTING.md. Thanks @RichardLitt. Also moved documentation from inside the repository to the wiki.

7. Added color logging and now chia_harvester will periodically announce which plots it is currently farming and their k sizes.

8. Fixed a typo in the UI. Hat tip to @lvcivs for the pr.

9. Clarified the minimum version of boost required to build timelord/VDFs. Hat tip @AdrianScott

10. Lots of smaller bug and documentation fixes.

Alpha-1.0

This is the first release of the Chia testnet! Blockchain consensus, proof of time, and proof of space are included.

Alpha 1.2

Chia Blockchain Testnet alpha 1.2 2020-01-08

  1. Performance improvements
     - Removes database access from blockchain, and handles headers instead of blocks
     - Avoid processing blocks and unfinished blocks that we have already seen.
     - Also adds test for load.
  2. Improvements to plotting via lookup table - as much as 15% faster
  3. Fixed a blockchain initialization bug

Alpha 1.1.1

Chia Blockchain Testnet alpha 1.1.1 2019-12-25

Alpha 1.1

Chia Blockchain Testnet alpha 1.1 2019-12-12

  1. FullNode: A long running or low ulimit situation could cause an “out of files” issue which would stop new connection creation. Removed the underlying socket leak.
  2. FullNode: Multiple SSH UI bugs fixed.
  3. Timelord VDF submission and management logic upgraded.
  4. Introducer now makes sure it only sends peer addresses to peers of peers that it can reach on port 8444 or their UPnP port.
  5. Updated blspy requirement to address an issue in the underlying bls-signatures library.
  6. Harvester: Farming  a plot of k = 30 or greater could lead to a segfault in the harvester.
