XBlock-EOS: Extracting and Exploring Blockchain Data From EOSIO

Abstract

Blockchain-based cryptocurrencies and applications have flourished the blockchain research community. Massive data generated from diverse blockchain systems bring not only huge business values and but also technical challenges in data analytics of heterogeneous blockchain data. Different from Bitcoin and Ethereum, EOSIO has richer diversity and higher volume of blockchain data due to its unique architectural design in resource management, consensus scheme and high throughput. Despite its popularity (e.g., 89,800,000 blocks generated till Nov. 14, 2019 since its launching in June 8, 2018), few studies have been made on data analysis of EOSIO. To fill this gap, we collect and process the up-to-date on-chain data from EOSIO. We name these well-processed EOSIO datasets as XBlock-EOS, which consists of 7 well-processed datasets: 1) Block, Transaction and Action, 2) Internal and External EOS Transfer Action, 3) Contract Information, 4) Contract Invocation, 5) Token Action, 6) Account Creation, 7) Resource Management. It is challenging to process and analyze high volume of raw EOSIO data and establish the mapping from original raw data to the fine-grained datasets since it requires substantial efforts in exacting various types of data as well as sophisticated knowledge on software engineering and data analytics. Meanwhile, we present statistics and exploration on these datasets. Moreover, we also outline the possible research opportunities based on XBlock-EOS.

Scaling Blockchains: Can Committee-Based Consensus Help?

“…For instance, one drawback of electing committees (as in Cosmos, EOS and TRON) as opposed to selecting random committees (as in Algorand) is that elections seems to lead to stagnation, especially early on in the blockchain life-cycle. EOS represents a rather extreme example: The first 89 million EOS blocks were mined by only 63 distinct producers Zheng et al (2020b). By comparison, the first 655,000 Bitcoin blocks were mined by more than 275,000 distinct addresses, and the first 8 million Ethereum blocks were mined by over 5000 distinct addresses Zheng et al…”
