Developer’s Perspective: Overview of the Tezos Blockchain Ecosystem

Want to build secure dApps without learning a niche language? Tezos lets you write smart contracts using familiar Python or TypeScript-like syntaxes, making development accessible and powerful.

#1about 3 minutes

Understanding the core features of the Tezos blockchain

Tezos is a liquid proof-of-stake blockchain with smart contract capabilities and a built-in on-chain governance mechanism for seamless upgrades.

#2about 3 minutes

Exploring the functional programming culture of Tezos

The Tezos ecosystem has strong roots in functional programming languages like OCaml, emphasizing a security-first mindset and formal verification to ensure code correctness.

#3about 2 minutes

What are decentralized applications or dApps

Decentralized applications use a public blockchain as a single source of truth, prioritize user sovereignty over data and identity, and operate without a central administrator.

#4about 3 minutes

Understanding the three-layer architecture of a dApp

A typical dApp consists of three layers: the immutable smart contract for business logic, a middleware indexer for efficient data querying, and the user-facing interface.

#5about 3 minutes

Writing smart contracts with high-level languages

Developers can write Tezos smart contracts using high-level languages like SmartPy (Python-based) or LIGO, which offers familiar syntaxes like JavaScript and compiles down to Michelson.

A code walkthrough of a JsLIGO smart contract

This example demonstrates building a simple "Taco Shop" smart contract using JsLIGO, covering type definitions, storage management, and function logic.

#7about 2 minutes

A code walkthrough of a SmartPy smart contract

This example shows how to implement the same "Taco Shop" contract using SmartPy, highlighting its Python-like syntax and built-in testing features.

#8about 2 minutes

The role of middleware and indexers in dApps

Middleware indexers like Better Call Dev are crucial for dApp performance by providing fast, convenient access to blockchain data that isn't natively indexed on-chain.

#9about 2 minutes

Building the user interface with Taquito and Beacon

The user interface layer of a Tezos dApp is built using the Taquito TypeScript library for node interaction and the Beacon standard for seamless wallet connectivity.

#10about 2 minutes

An overview of testing tools for Tezos contracts

The Tezos ecosystem provides robust tooling for both unit testing, with frameworks in LIGO and SmartPy, and integration testing using tools like Flexesa and PyTezos.

#11about 5 minutes

Getting started with templates and online IDEs

Developers can quickly start building on Tezos using online IDEs for SmartPy and LIGO, which provide contract templates and integrated testing environments.
