Hackathons
Blockchain Testnets
- Cosmos Game of Zones: My team Astronomia helped test and attack the IBC relayer component, keeping connections live with minimum packets for Challenge 1 and sending a large number of messages to all zones to stress test it for Challenge 2.
- Elrond Battle of Nodes: Submitted scripts for signing transactions with a private key instead of a mnemonic, sent batched messages to complete missions faster, and ran nodes.
- Avalanche Denali: Ran nodes and submitted a PR for supporting REST requests over gRPC calls.
- Witnet 2020: Created a bot for node operators, modified ethstats into a Witnet netstats frontend, wrote the Witnet net backend from scratch, submitted bugs, and ran nodes.
Bug Bounty
- Witnet DOS Bug: The issue was caused by unterminated connections, which I hijacked by sending a large number of malformed protobuf messages.
