  • Investigate packet loss in libp2p, Network, fixing a bug with lost packets related to the usage of Cuckoo-filters
  • View Changes for Micro Blocks, Consensus, view change is an essential part of the consensus protocol
  • View Changes for Key Blocks, Consensus`, view change is an essential part of the consensus protocol
  • Determine Epoch Length && Block Time, Consensus, epoch length and block time are important parameters of the consensus protocol
  • HashCash Algorithm, Network, nodes have to solve HashCash puzzles in order to join the network to prevent Sybil attacks
  • Unicast Messages Encryption, Network, unicast messages traveling over Kademlia DHT network have to be encrypted
  • Test cases for block validation, Core Blockchain, part of the functional testing harness
  • RaptorQ Encoder/Decoder, Network, required to create optimized protocol for transmission of blocks/other large messages


  • Kademlia DHT-based routing, Network, base networking functionality for unicast messages
  • WebSocket API for Wallet. Wallet, needed to support GUI Wallet
  • Progress Tracking for Bootstrap, Wallet, needed to support GUI Wallet

Not yet started:

  • Unicast based on Kademlia DHT routing, Network
  • Rollback of Monetary Transactions in Wallet, Wallet, this mechanism is needed due to fork resolution
  • Multiple Transactions In A Row, Block Validation, allowing nodes to construct chained transactions on the same block height
