Download All Ethereum Addresses With Balance
Justina Sisti
I've been playing around with BigQuery's Ethereum ETL. There's a table specifically for mapping wallet addresses to eth balances in gwei. Lots of addresses work just fine, but in the example below you'll find one famous wallet (Justin Beiber) that definitely has eth, but doesn't appear in the table
It appears some addresses do not appear in the balances tables correctly.It may be due to an issue with addresses which have polygon and eth transactions. I have seen other examples of this phenomena.
Using web3 I can query the balance of any fixed account with web3.eth.getBalance. Assuming I have the entire blockchain downloaded, how can I recover the list of all addresses that have a positive balance at this moment?
to show top 10 ethereum addresses with a positive balance. You can run this at GCP BigQuery portal.Then export results into CSV file. Remove last limit line to find all addresses, however there are some export limits, E.g. you can export up to 16k rows to local CSV file, or up to 1G to Google Drive, or save all results as BigQuery table. Run it only few times, to avoid exceeding your free quota.
In a development environment, it is possible to send transactions from an address without having that addresses private key. To create an Account object from an arbitrary address, use the Accounts.at method and include force=True as a keyword argument:
This real-time notification pairs nicely with the Transfers API (currently in beta) which allows our developers to get historical transaction data for ethereum addresses. For example, imagine if you were building a wallet application and a new user signs up.
Ether (ETH) is the cryptocurrency generated in accordance with the Ethereum protocol as a reward to validators in a proof-of-stake system for adding blocks to the blockchain. Ether is represented in the state as an unsigned integer associated with each account, this being the account's ETH balance denominated in wei (1018 wei = 1 ether).[55] At the end of each epoch, new ETH is generated by the addition of protocol-specified amounts to the balances of all validators for that epoch, with the block proposers receiving the largest portion. Additionally, ether is the only currency accepted by the protocol as payment for the transaction fee. The transaction fee is composed of two parts: the base fee and the tip. The base fee is "burned" (deleted from existence) and the tip goes to the block proposer. The validator reward together with the tips provide the incentive to validators to keep the blockchain growing (i.e. to keep processing new transactions). Therefore, ETH is fundamental to the operation of the network. Ether may be "sent" from one account to another via a transaction, which simply entails subtracting the amount to be sent from the sender's balance and adding the same amount to the recipient's balance.[56]
Ethereum addresses are composed of the prefix "0x" (a common identifier for hexadecimal) concatenated with the rightmost 20 bytes of the Keccak-256 hash of the ECDSA public key (the curve used is the so-called secp256k1). In hexadecimal, two digits represent a byte, and so addresses contain 40 hexadecimal digits after the "0x", e.g. 0xb794f5ea0ba39494ce839613fffba74279579268. Contract addresses are in the same format, however, they are determined by sender and creation transaction nonce.[24]
The ERC-20 (Ethereum Request-for-Comments #20) Token Standard allows for fungible tokens on the Ethereum blockchain. The standard, proposed by Fabian Vogelsteller in November 2015, implements an API for tokens within smart contracts. The standard provides functions that include the transfer of tokens from one account to another, getting the current token balance of an account, and getting the total supply of the token available on the network. Smart contracts that correctly implement ERC-20 processes are called ERC-20 Token Contracts, and they keep track of created tokens on Ethereum. Numerous cryptocurrencies have launched as ERC-20 tokens and have been distributed through initial coin offerings.[63]
