BigQuery-Ethereum-Classic-Blockchain

Complete live Ethereum Classic historical blockchain data (BigQuery)

Context

Ethereum Classic is an open-source, public, blockchain-based distributed computing platform featuring smart contract (scripting) functionality. It provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. Ethereum Classic and Ethereum have a value token called “ether”, which can be transferred between participants, stored in a cryptocurrency wallet and is used to compensate participant nodes for computations performed in the Ethereum Platform.

Ethereum Classic came into existence when some members of the Ethereum community rejected the DAO hard fork on the grounds of “immutability”, the principle that the blockchain cannot be changed, and decided to keep using the unforked version of Ethereum. Till this day, Etherum Classic runs the original Ethereum chain. Content

In this dataset, you will have access to Ethereum Classic (ETC) historical block data along with transactions and traces. You can access the data from BigQuery in your notebook with bigquery-public-data.crypto_ethereum_classic dataset. Querying BigQuery tables

You can use the BigQuery Python client library to query tables in this dataset in Kernels. Note that methods available in Kernels are limited to querying data. Tables are at bigquery-public-data.crypto_ethereum_classic.[TABLENAME]. Fork this kernel to get started. Acknowledgements

This dataset wouldn’t be possible without the help of Allen Day, Evgeny Medvedev and Yaz Khoury. This dataset uses Blockchain ETL. Special thanks to ETC community member @donsyang for the banner image. Inspiration

One of the main questions we wanted to answer was the Gini coefficient of ETC data. We also wanted to analyze the DAO Smart Contract before and after the DAO Hack and the resulting Hardfork. We also wanted to analyze the network during the famous 51% attack and see what sort of patterns we can spot about the attacker.


BigQuery以太坊eth经典区块链blockchain

完整的实时以太坊eth经典历史区块链blockchain数据(BigQuery)

上下文

Ethereum Classic是一个开源、公共、基于区块链blockchain的分布式计算平台,具有智能合约(脚本)功能。它提供了一个分散的图灵完整虚拟机,即以太坊eth虚拟机(EVM),它可以使用公共节点的国际网络执行脚本。以太坊eth经典版和以太坊eth有一个名为“以太”的价值代币,可以在参与者之间转移,存储在加密货币钱包中,用于补偿参与者节点在以太坊eth平台上执行的计算。

以太坊eth经典版诞生之时,以太坊eth社区的一些成员以“不变性”为由拒绝了DAO硬分叉,即区块链blockchain不能改变的原则,并决定继续使用未格式化的以太坊eth版本。直到今天,以太经典仍然运行着最初的以太坊eth链。内容

在此数据集中,您可以访问以太坊eth经典版(ETC)的历史数据块数据以及事务和跟踪。您可以使用BigQuery public访问笔记本中BigQuery中的数据-data.crypto逯ethereum_经典数据集。查询BigQuery表

可以使用BigQuery Python客户机库在内核中查询此数据集中的表。请注意,内核中可用的方法仅限于查询数据。表位于bigquery public-data.crypto逯ethereum_经典[表名]。分叉这个内核开始。致谢

如果没有艾伦·戴、叶夫根尼·梅德韦杰夫和亚兹·库里的帮助,这个数据集就不可能实现。此数据集使用区块链blockchainETL。特别感谢ETC社区成员@donsyang提供的横幅图片。启发

我们想回答的主要问题之一是ETC数据的基尼系数。我们还想分析DAO攻击前后的DAO智能合约以及由此产生的Hardfork。我们还想分析著名的51%攻击期间的网络,看看我们能发现哪些类型的攻击者。
