BOB batches users' transactions and submits them to Ethereum, paying a share of the transaction fees to Ethereum validators (expense).

BOB is an L2 smart contract platform for decentralized applications on Ethereum. BOB was founded by Alexei Zamyatin and Dominik Harz and launched in 2024.

BOB team & investors own and govern the protocol. BOB's investors include Castle Island Ventures, IOSG Ventures, Coinbase Ventures, etc.

# BOB (Build on Bitcoin) Active users (daily) Methodology

## 1. Overview

The BOB daily active users (DAU) metric measures the number of unique addresses that initiated at least one transaction on the BOB blockchain within a given day. This metric provides insight into daily user engagement and activity levels on the BOB Layer 2 network. The calculation follows a straightforward approach: identify all transaction senders within each day and count distinct addresses.

## 2. Data sources

The calculation relies on the following raw data sources:
- **BOB blockchain transactions**: Complete transaction records from the BOB Layer 2 blockchain, including transaction metadata and sender addresses
- **Transaction timestamps**: Block timestamps from BOB blockchain blocks to determine daily boundaries
- **Transaction sender addresses**: The `from_address` field from BOB transactions, representing users who initiated transactions

## 3. Step-by-step calculation

### Component A: User identification
- **Purpose**: Extract and classify all transaction senders as active users
- **Logic**: The calculation begins by identifying all addresses that sent transactions on the BOB blockchain. Each transaction sender address is extracted from BOB transaction records and classified as a "Transaction sender" user type. The system applies safe casting to ensure address format consistency and includes transaction timestamps for temporal analysis. All users are categorized under the BOB blockchain with business metadata indicating this is a Layer 2 blockchain in the blockchain business segment.
- **Key fields**: `from_address` (transaction sender), `block_timestamp` (transaction timing), `transaction_hash` (for record identification)

### Component B: Daily aggregation  
- **Purpose**: Group user activity by daily boundaries and count distinct users
- **Logic**: Transaction timestamps are truncated to daily granularity, creating daily time buckets for user activity aggregation. Within each day, the system applies a distinct count operation on user addresses to ensure each unique address is counted only once per day, regardless of how many transactions they sent. This eliminates double-counting of users who performed multiple transactions within the same day.
- **Key fields**: `timestamp` (daily boundary), `user_address` (distinct user identifier), `user_dau` (final user count field)

### Final aggregation
- **Combining components**: The user identification and daily aggregation are combined in a single query that processes all transaction senders and groups them by truncated daily timestamps
- **Currency conversion**: Not applicable - this is a count metric without monetary values
- **Time aggregation**: Daily boundaries are created using timestamp truncation to day level, with incremental processing logic that looks back a configurable number of days to handle late-arriving data
- **Final calculation**: The final BOB DAU value represents the count of distinct addresses that sent at least one transaction on the BOB blockchain within each daily period, providing a measure of unique daily user activity
