This is a joint interest group by UCI CS working groups to understand the other partners' fields better, explore new ideas, and collaboration opportunities. The bi-weekly meetings are characterized by highly interactive sessions with a mixture of i) fundamentals presentations, ii) stimulus presentations, iii) brainstorming sessions, iv) constructive discussions, v) status reports, and of course, vi) hard work back in the lab. We let students from our labs participate in all parts. For the second quarter 2020, we switched from physical meetings to video conferencing.

The goal is the establishment of a practical blockchain competence in ICS. This cooperation is supported by an ICS Endeavor grant.

Artifacts and Datasets

Ethereum Transactions as CSV

46GB, including up to block 8836290
Format: unixtime,pos,fromAddr,toAddr,valueWei,transactionHash,blockNum,blockHash,nonce,dataLen
Ether transactions have value>0 && dataLen==0. Smart contracts have dataLen > 0.

Ethereum Rewards as Explicit CSV Transactions

271MB, including up to block 8836290
Unlike Bitcoin, Ethereum does not explicitly record block rewards as transactions. This data set recreates block rewards (i.e., the generation of new Ether) in the same format as above.
