I’ve been building something called the Paybyte Blockchain Engine, or PBE, and mainnet is finally live after more coffee than my kidneys would like to admit. I always thought it would be cool to have something easy to use, more mainstream, that's as easy to implement like a "Pay with Paypal" button, but for crypto, that's easy for the average user, like the litecoin network, and something that is considerably more environmental friendly than a POW concept like Bitcoin. Since my Java/C++ skills suck, I built it in a language I am familiar with, and something that is a little out of the ordinary for a blockchain, PHP.

This is its own Layer 1. Not an ERC20, not a Solana token, not a rebranded fork.

Current mainnet:

PBE Core 0.0.1 Protocol 1.0 Block v4 Transaction v2 PBE-PAY v1 15 second block target 5 PBE starting reward ~4 year halvings ~84.1M max supply

Consensus uses hybrid participation.

Any authorized wallet can produce blocks, even with 0 PBE. Each wallet gets one deterministic Argon2id participation ticket per slot. Holdings improve timing through a bounded multiplier, but there is no minimum stake and no manual staking lock. The entire ecosystem is fully P2P.

PBE exposes separate P2P and RPC layers.

Examples:

POST /p2p/hello POST /p2p/transaction POST /p2p/block GET /p2p/peers GET /rpc/status GET /rpc/block/{heightOrHash} GET /rpc/transaction/{txid} GET /rpc/balance/{address} POST /rpc/broadcast

There’s also a native merchant protocol called PBE-PAY.

Payments use transaction v2 with a signed paymentReference.

A merchant verifies:

paymentReference recipient exact amount

Payment URIs look like:

pbe:<address>?amount=25&ref=ORDER123&label=Store

Merchants can use their own node, or multiple public nodes

Commerce endpoints include:

GET /rpc/commerce/info POST /rpc/commerce/payment-request GET /rpc/commerce/payment/{reference} POST /rpc/broadcast

Optional HMAC signed webhooks support:

payment.pending payment.confirming payment.confirmed payment.reorged payment.expired

The full API is public and viewable at

Windows and Linux standalone nodes are also available. The Windows build is basically download, extract, run the PBE, create a wallet and sync.
