In particular, each sample holds the creation and runtime bytecodes. When available, the sources are also included. ## Metadata > the dataset is not yet complete! - homepage: [https://github.com/apehex/feedblocks][github-project] - version: 0.1.6 - download size: 1.8 GB | Split | Samples | Blocks | Scraped sources | | ------------- | --------- | ------------------------- | --------------------------------- | | 'ethereum' | 1,294,252 | 19,493,000 - 20,292,000 | 19,493,000 - 19,785,999 (36%) | The transaction data is available for all records, in particular creation and runtime bytecodes are filled. But the source code cannot be collected via standard RPC nodes, they have to be obtained through the APIs of block explorers. These have a small rate limit and it takes a long time. So the source code data has only been scraped for a portion of the records, as listed in the table above. ## Features ```python datasets.Features({ "chain_id": datasets.features.Value(dtype='uint64'), "block_number": datasets.features.Value(dtype='uint64'), 'block_hash': datasets.features.Value(dtype='string'), 'transaction_hash': datasets.features.Value(dtype='string'), 'deployer_address': datasets.features.Value(dtype='string'), 'factory_address': datasets.features.Value(dtype='string'), 'contract_address': datasets.features.Value(dtype='string'), 'creation_bytecode': datasets.features.Value(dtype='string'), 'runtime_bytecode': datasets.features.Value(dtype='string'), 'creation_sourcecode': datasets.features.Value(dtype='string'),}) ``` ### Block Number The block number is the only integer feature. ### Solidity Sources The sources all have open source licenses. They were collected from block explorer APIs like [Etherscan][etherscan-api]. The sources are formatted as [standard JSON input][solidity-docs-json] for the solidity compiler. The resulting JSON is then encoded using UTF-8 into a single string. ### HEX Data All the other features are HEX encoded into strings, **without** the `0x` prefix. For example: ```python { 'chain_id': 1, 'block_number': 20155815, 'block_hash': 'fcddf33b1b5a728a40588eda60262639201ac0d3f611f08286a9e2ef65576111', 'transaction_hash': 'ec3723ffb8a3bbb8b83b25481f61cbfc46383fc88ff8eb364186b53aa226e4bf' 'deployer_address': 'ba57abe375903838b5c19709e96dae12191fa37e', 'factory_address': '0000000000b3f879cb30fe243b4dfee438691c04', 'contract_address': 'eff10e7d4feef60ed9b9e9bb9fee12c2504bd0ba', 'creation_bytecode': '756eb3f879cb30fe243b4dfee438691c043318585733ff6000526016600af3', 'runtime_bytecode': '6eb3f879cb30fe243b4dfee438691c043318585733ff', 'solidity_sourcecode': '',} ``` ## Raw Data The original data is stored in parquet files, and typed as raw bytes: ```python pa.schema(fields=[ pl.field('chain_id', pa.uint64()), pl.field('block_number', pa.uint32()), pl.field('block_hash', pa.large_binary()), pl.field('transaction_hash', pa.large_binary()), pl.field('deployer_address', pa.large_binary()), pl.field('factory_address', pa.large_binary()), pl.field('contract_address', pa.large_binary()), pl.field('creation_bytecode', pa.large_binary()), pl.field('runtime_bytecode', pa.large_binary()), pl.field('creation_sourcecode', pa.large_binary()),]) ``` This data is collected by the [scripts of a dedicated package, feedblocks][github-project].
