Hi everyone,

I want to share **Block Engine v2.2.0**, an open-source polyglot multi-runtime execution engine designed to eliminate the friction of combining multiple programming languages in software development.

Modern applications often leverage different languages for their unique strengths:

`hash`

, `openssl`

).Traditionally, orchestrating these runtimes requires setting up microservices, gRPC, Docker containers, or manual JSON IPC file reading/writing.

Block Engine solves this by introducing a **Zero-Dependency Polyglot Pipeline**.

You write native code blocks (`<py>`

, `<js>`

, `<lua>`

, `<php>`

) inside a single `.blkp`

document. Block Engine parses the AST, executes each runtime in isolated subprocesses, and **automatically serializes and transfers state variables** from one language to the next.

<py>
# Python Stage: Compute analytics data
raw_prices = [100.5, 102.1, 101.8, 105.4, 108.0]
ma5 = sum(raw_prices) / len(raw_prices)
user_name = "Gemini Master"
</py>

<js>
// Node.js Stage: Automatically receives Python variables (user_name, ma5)
console.log(`[Node.js] Received user: ${user_name}, MA5: ${ma5.toFixed(2)}`);
var final_score = Math.round(ma5);
</js>

<lua>
-- Lua 5.4 Stage: High-speed recursive computation
function fib(n)
    if n <= 1 then return n end
    return fib(n-1) + fib(n-2)
end
lua_result = fib(10)
</lua>

<php>
// PHP 8 Stage: Cryptographic SHA-256 Signature
$signature = hash('sha256', $user_name . '|' . $final_score);
echo "[PHP] Audit SHA-256: " . $signature . "\n";
</php>
