#1 about 2 min

The Bitcoin SV UTXO smart contract model

How the unspent transaction output structure enables programmable functionality beyond simple transfers.

#2 about 4 min

Abstracting native script with a high-level language

Replacing low-level assembly syntax with intuitive constructs to simplify contract development.

#3 about 4 min

Writing a basic smart contract in sCrypt

Defining state variables, constructors, and public functions to build functional logic.

#4 about 4 min

Setting up the sCrypt VS Code extension

Installing the desktop IDE integration to gain syntax highlighting and autocomplete capabilities.

#5 about 2 min

Using sCrypt Studio for web-based development

Accessing a cloud IDE to compile, run, and visually inspect contract execution without local setup.

#6 about 6 min

Testing contracts with JavaScript frameworks

Implementing automated test coverage for smart contracts using tools like Mocha and Chai.

#7 about 6 min

Debugging contract logic within VS Code

Identifying implementation flaws by setting breakpoints and inspecting local variables during test evaluation.

#8 about 6 min

Deploying and interacting with live contracts

Compiling code and broadcasting unlocking transactions to the test network.

#9 about 5 min

Accessing boilerplates and official language documentation

Referencing syntax specifications and cloning repository templates to start new web3 projects.

#10 about 3 min

Finding educational resources for blockchain programming

Locating developer curriculums and wikis tailored specifically to the SV ecosystem.

#11 about 3 min

Managing non-fungible tokens in contract logic

Updating standard mechanisms to validate set equality rather than numerical balances for unique assets.

#12 about 5 min

Enabling code reuse and inline assembly

Packaging functions into shareable libraries and embedding native script for optimized low-level execution.

#13 about 2 min

Removing the gas model constraint
