PascalCoin is an instant, zero-fee, infinitely scalable, decentralized cryptocurrency with advanced privacy and smart contract capabilities. It is the world's first blockchain independent of historical operations.

PascalCoin possesses unlimited potential.

PascalCoin is a peer-to-peer cryptocurrency written in Object Pascal. PASC is its currency, and a PASA is a numbered account. This repository contains two desktop wallets, a node daemon and a reference miner. PascalCoin's original implementation is by Albert Molina, with significant contributions by Herman Schoenfeld (such as the Experimental Wallet and core changes), alongside the work of the PascalCoin contributors.

PascalCoin 5.9.5 archives contain all four applications. Drag the wallet apps from the macOS disk image to Applications. They run natively on Apple silicon and Intel Macs.

Verify packages against the release's SHA256SUMS. See Build 5.9.5 for the patch changes. All releases include earlier mainnet and testnet builds.

The macOS apps are not notarized. On first start, click Open Anyway for each app in System Settings > Privacy & Security. On macOS 14 and earlier, Control-click the app and choose Open.

Keep locale, miner resources, runtime libraries and license notices beside the extracted executables. Launch Linux GUI builds from the extracted folder. They need GTK2.

The experimental wallet provides:

The feature map lists the classic equivalents, and the wallet guide and Build 5.9 changes give details.

Startup, node status and a batch account-type change

Startup and account setup	Wallet and operation review
Delphi: cancelable local blockchain loading.	FPC: wallet accounts and pending operations.
Delphi: node status, chain statistics and mining information.	FPC: review account changes, signer and fees before execution.
Delphi: review 267 selected accounts in the account-information wizard.	FPC: scrollable results for 267 account-information operations.
Delphi: account name, type, fee and payload options.	Delphi: custom per-operation fee, total fee and a single fee payer.

The source includes its Pascal libraries. The experimental wallet's build guide covers compiler options and runtime layout.

With lazbuild and FPC, build all four applications into src, named as in the application table, on Windows, Linux or macOS. Run from the repository root:

lazbuild -B src/pascalcoin_daemon.lpi
lazbuild -B src/pascalcoin_miner.lpi
lazbuild -B src/pascalcoin_wallet_classic.lpi
lazbuild -B src/pascalcoin_wallet_experimental.lpi

For the experimental wallet, add --build-mode=Release for an optimized build or --build-mode=Debug for debugging. Default is unoptimized.

• On macOS, add --ws=cocoa to both wallet commands. Linux uses GTK2.
• On Windows and Linux, copy OpenSSL 1.1 from windows-dll or linux-libs beside the programs.
• Keep src/locale and src/pascalsha.cl with distributed programs.
• On macOS, bash build/macOS/package-macos.sh src dist packages both wallets in a disk image. See build/README.md.

On Windows, open pascalcoin_wallet_classic.dproj or pascalcoin_wallet_experimental.dproj in the Delphi IDE. The builds write src/pascalcoin_wallet_classic.exe and src/pascalcoin_wallet_experimental.exe. Only classic Win64 Release and experimental Win64 Debug builds from Delphi 13 Community Edition are verified.

In editions with command-line compilers, run from the repository root in the RAD Studio Command Prompt:

msbuild src\pascalcoin_wallet_classic.dproj /t:Build /p:Config=Release /p:Platform=Win64
msbuild src\pascalcoin_wallet_experimental.dproj /t:Build /p:Config=Release /p:Platform=Win64

In Community Edition, select the configuration and platform in the IDE, then run AutoBuild:

bds.exe -b src\pascalcoin_wallet_classic.dproj
bds.exe -b src\pascalcoin_wallet_experimental.dproj

See Embarcadero's MSBuild guide and IDE command options.

On Windows with Lazarus/FPC, build the experimental wallet, then run from the repository root:

& .\src\tests\experimental\RunAllWalletTests.ps1

Add -FpcPath, -LazarusDirectory, -WalletExecutable and a new -OutputDirectory as needed. Tests run offline on private Windows desktops with temporary keys and data. The test guide describes the coverage, the portable lock tests for Linux and macOS, Delphi probes and optional large-chain fixtures.

For a separate experimental wallet session, use a new data folder:

& .\src\PascalCoinWalletExperimental.exe --data-dir="<new-data-folder>" --offline --no-startup-dialogs

--offline disables peers, listening, RPC and mining for that run only.

PascalCoin uses the Sphere 10 Pascal Framework, imported into src/libraries/sphere10.
