v0.8.0

Code

• Merge Blockchain::Tree into Blockchain
• Remove Blockchain::Array

v0.7.1

Node

• Fix a bug in which a node with --local option, wasn't broadcasting the
  mined blocks
• Don't log blockchain when reading from the network or filesystem

Code

• Add Blockchain#verbose property

v0.7.0

Node

• Make /blocks/ endpoint handle index range and array
• Download 1000 blocks at a time when syncing with the network

Code

• Add {Blockchain, Network, Node}#blocks_at

v0.6.0

Code

• Add Blockchain::Tree implementation replacing the array implementation

v0.5.0

Node

• Relay network blocks If they haven't been seen before
• Fix bugs in Storage::File and Storage::Network
• Update CLI options' descriptions

Code

• Add Storage::Network.check_sync_status
• Add Storage::Network.find_mutual_block

v0.4.1

Node

• Fix hex overflow bug in Difficulty.multiply which resulted in higher
  difficulty while It was trying to reduce the difficulty
• Fix Storage::Network bug which caused broadcasting existing block

Code

• Add experimental bench/ directory for benchmarking

v0.4.0

Node

• Broadcast blocks to network if the local blockchain has higher index,
• Remove the node from the network when it is closed
• Fix a bug which caused some validations to be skipped if the chain is being reseted
• Improve miner so that as soon as a new block is added by network, It moves on
  to the next index.

Code

• Add Block.calculate_hash, {Network, Node}#last_block
• Rename {Network, Node}#download_block to {Network, Node}#block_at

v0.3.1

Node

• Fix critical blockchain bug which prevented resetting the chain
• Make miner skip the mined block if another block is already added to chain with the
  same index
• Use different colors for logs

v0.3

Protocol

• Adjust difficulty every 60 blocks
• Much more accurate difficulty calculation
• Change websocket messages to have different types. Currently Block or IP information
  can be sent through the socket.
• Add /nodes endpoint that returns the known nodes' ips

Node

• Connect to Network::TESTNET_SEED_HOST by default
• Explore the network continuously for new public nodes and connect
• Traverse blockchain backwards from the seed node if there is a hash mismatch
• Delete the block file if it's not added to the blockchain
• Broadcast our block to the network if the received block is not preferred
• Add CLI options
  • --seed-ip=IP
  • --host-ip=IP
  • --port=PORT
  • --local-net
  • --mine
  • --web
  • --version
  • --help

v0.2

Protocol

• Adjust difficulty using bits
• Use websocket for broadcasting solved blocks
• Remove /connect and /relay endpoints

Implementation

• Store blockchain in .block/ folder
• Add Cli, Difficulty, Emitter, Miner, Node, Storage, Web modules
• Use proper shard folder structure
