Stacks miners batch users' transactions and receive fees from users (supply-side fees). Miners submit transactions to Bitcoin, paying a share of the transaction fees to Bitcoin miners.

Stacks is an smart contract platform for creating decentralized applications on Bitcoin (a blockchain). Stacks was founded by Muneeb Ali and Ryan Shea, and launched in 2021.

STX tokenholders own and govern the protocol. They currently do not take a cut of the total transaction fees paid by users (revenue). Stacks' investors include IOSG Ventures, The Spartan Group, Hashkey Exchange, etc.

# Stacks Contract deployers Methodology

## 1. Overview

The Stacks contract deployers metric measures the number of unique addresses that deployed smart contracts on the Stacks blockchain each day. On Stacks, smart contract deployments are identified by the `smart_contract` transaction type. The contract address follows the format `{deployer_address}.{contract_name}`, where the deployer is the transaction sender (`from_address`). This metric provides insight into developer activity and ecosystem growth on the Stacks network.

## 2. Data sources

- **Stacks blockchain transaction data**: Transaction records containing sender addresses (`from_address`), block timestamps, and transaction types including `smart_contract` for contract deployments

## 3. Step-by-step calculation

### Component A: Contract deployment identification
- **Purpose**: Identify all smart contract deployment transactions on Stacks
- **Logic**: Filter Stacks transactions to include only those with `transaction_type = 'smart_contract'`, which represent contract deployment operations. The `from_address` field identifies the deployer address. Each deployment transaction represents a unique contract being deployed to the network.
- **Key fields**: `from_address` (deployer address), `block_timestamp` (deployment time), `transaction_type` (filter for 'smart_contract')

### Component B: Daily deployer aggregation
- **Purpose**: Count unique deployer addresses per day
- **Logic**: Block timestamps are truncated to daily boundaries. Within each day, distinct `from_address` values from smart contract deployment transactions are counted. This ensures each deployer is counted only once per day, regardless of how many contracts they deployed. Metadata fields are applied including `chain_id` as 'stacks' and `market_sector_id` as 'blockchains_l2'.
- **Key fields**: `timestamp` (daily), `contract_deployers` (distinct deployer count)

### Final aggregation
- **Combining components**: Daily deployer counts are processed through a finalization macro for schema validation and temporal completeness
- **Currency conversion**: No currency conversion required as this is a count-based metric
- **Time aggregation**: All data is aggregated to daily boundaries using timestamp truncation
- **Final calculation**: The final metric value represents the count of distinct addresses that deployed at least one smart contract on Stacks within each daily time period, with zero values filled for any missing days
