Validators process transactions and receive fees from users (supply-side fees).

Solana is a smart contract platform for decentralized applications (a blockchain). Solana was founded by Anatoly Yakovenko, Greg Fitzgerald, Raj Gokal, etc. and launched in 2020.

SOL holders own and govern the protocol. They currently take a cut of the transaction fees paid by users (revenue). Solana’s investors include Polychain Capital, ParaFi capital, Passport capital, etc.

# Solana Slot count Methodology

## 1. Overview

Slot count measures the number of slots in which a leader produced a block on Solana. Slots are defined as the fixed time intervals allocated by the network for block production, meaning the count is reduced below the theoretical maximum whenever a slot is skipped by a leader. Network reliability is reflected by this metric through its conversion of scheduled production opportunities into blocks. Validator performance and overall network stability are evaluated using this metric.

## 2. Data sources

- **Blockchain events**: Block production records from the Solana blockchain, covering Solana

## 3. Step-by-step calculation

### Component A: Block count extraction

- **Purpose**: Extract and count the blocks produced during each slot
- **Logic**: Block records are queried from the Solana blockchain. Each successfully produced block is counted to determine the total number of slots in which a leader successfully produced a block. Slots where a leader skipped block production are excluded from this count.
- **Key fields**: `block_timestamp` (timing), `slot_count` (block count)

### Component B: Daily aggregation and normalization

- **Purpose**: Aggregate slot counts to a daily granularity and ensure data continuity
- **Logic**: Block timestamps are truncated to day boundaries in UTC. Slot counts are summed for each daily interval. Missing days are assigned a value of zero to ensure data continuity, and the final values are cast to a standardized numeric format.
- **Key fields**: `daily_timestamp` (timing), `slot_count` (aggregated block count)
