How to Use DALI for Tezos Comparison

Intro

DALI provides a standardized interface to query Tezos blockchain data, enabling side‑by‑side comparison across networks. By aggregating on‑chain metrics, it helps developers, analysts, and investors evaluate performance, staking rewards, and contract activity without writing custom scrapers.

Key Takeaways

• DALI aggregates raw Tezos data into a unified JSON schema.
• It supports filtering by baker, cycle, and token type.
• Comparison reports can be exported to CSV or visualized in dashboards.
• The tool works via a RESTful API, compatible with most programming languages.

What is DALI?

DALI, short for Data Abstraction Layer Interface, is an open‑source framework that abstracts Tezos node data into a consistent query model. It normalizes block headers, operations, and smart contract state, delivering a single endpoint for multiple network views.

Why DALI Matters

Blockchain ecosystems often lack consistent data formats, making cross‑network analysis time‑consuming. DALI eliminates that friction, allowing users to:

• Compare staking participation rates across Tezos and other blockchain platforms.
• Monitor contract deployment frequency in real time.
• Generate reports for investment due diligence without manual data cleaning.

How DALI Works

DALI’s core mechanism is a weighted scoring algorithm that translates raw metrics into a comparable “Network Health Index”. The formula is:

Score = (ActiveContracts × 0.4 + TxVolume × 0.3 + StakingParticipation × 0.3) / TotalWeight

Steps:

1. Connect to a Tezos node via DALI’s RPC wrapper.
2. Fetch block headers for the target cycles.
3. Aggregate operations (transactions, delegations, originated contracts).
4. Apply the weighting model to compute the Score.
5. Return JSON with both raw data and the computed Score.

Used in Practice

Suppose an investor wants to compare Tezos with a competing proof‑of‑stake chain. Using DALI, they can request metrics for the last 30 cycles, extract total active contracts, daily transaction volume, and staking participation, calculate the Network Health Index for both chains, and visualize results in a line chart to spot divergence.

Sample API call (Python):

import requests
url = "https://api.dali‑project.io/v1/comparison/tezos"
params = {"cycles": 30, "metrics": "all"}
r = requests.get(url, params=params)
print(r.json())

Risks / Limitations

• Data latency may reach up to two minutes during high‑traffic periods.
• DALI relies on publicly available node endpoints; if a node is misconfigured, metrics can be skewed.
• Weighting coefficients are static; users must manually adjust them for custom analysis.
• The tool does not cover off‑chain data, such as token price or market sentiment.

DALI vs TzStats vs GraphQL API

While TzStats offers a web UI for Tezos explorer data, it lacks a unified scoring model. The native GraphQL API provides raw data but requires complex joins. DALI sits in the middle: it delivers normalized metrics and a ready‑made comparison framework, reducing development time compared to building queries from scratch.

What to Watch

Future releases of DALI will incorporate on‑chain governance data and cross‑chain token transfers. Upcoming Tezos protocol upgrades (e.g., Ithaca 2) may alter staking participation calculations, so users should monitor DALI’s release notes for weight adjustments.
