• I am a contributor to the utreexo project which is a hashed based accumulator in golang. Utreexo is an ongoing project which provides an enhancement on how the bitcoin network verifies transactions by checking the utxo set of a user.
• Some of the issues I worked on are
• Wrote tests for testing the serialisation and deserialization of pollards which is a sparse representation of forest of binary trees in utreexo.
• Added a feature to write undoblocks data to disk which was missing earlier to handle the case of re orgs within the block chain. Developed a function to write undoblocks data retrieved from modifying the chain and passing the data from channel to go routine.
• Split up the proof generation and writing of the proof by channels into separate data blocks by the accumulator to prevent buffer overhead in the data. This was achieved by using separate go routines and channels to write different proofs of data in different directories.
