🖥️Desktop Wallet & maryjanecoind

Downloads — MaryJaneCoin Core 4.2.0

All seven builds come from the same guix-build-1997c3bcaccf/ output. Each ships both the Qt GUI (maryjanecoin-qt) and the daemon (maryjanecoind) with full privacy enforcement compiled in.

Verify the download

# macOS / Linux
shasum -a 256 maryjanecoin-4.2.0-*.tar.gz
sha256sum  maryjanecoin-4.2.0-*.tar.gz

# Windows PowerShell
Get-FileHash maryjanecoin-4.2.0-win64-setup.exe -Algorithm SHA256

# One-shot: compare against the SHA256SUMS file
curl -sO https://explorer.maryjanecoin.net/downloads/SHA256SUMS
sha256sum -c SHA256SUMS --ignore-missing

Install on Windows

1. Run the installer

   Double-click maryjanecoin-<version>-win64-setup.exe. SmartScreen may warn because the binary is newly signed — click More info → Run anyway.

2. Choose an install location

   Default is C:\Program Files\MaryJaneCoin\. Data goes to %APPDATA%\MaryJaneCoin\.

3. Launch MaryJaneCoin Core

   Start menu → MaryJaneCoin. On first run the daemon scans for a blockchain data directory; if none exists it'll download from peers starting at seeds.maryjanecoin.net. Allow a few hours on first sync.

Prefer the portable ZIP? Unzip anywhere, then run maryjanecoin-qt.exe from the bin\ folder. Data still lands in %APPDATA%\MaryJaneCoin\ unless you pass -datadir=.

Install on macOS

Pick the right arch: Apple Silicon (M1/M2/M3/M4) uses arm64-apple-darwin; older Intel Macs use x86_64-apple-darwin. Running under Rosetta works but is slower — prefer the native arch.

1. Extract the tarball

   cd ~/Downloads
   tar -xzf maryjanecoin-<version>-arm64-apple-darwin.tar.gz
   cd maryjanecoin-<version>/bin

2. First launch (Gatekeeper)

   macOS will quarantine unsigned binaries. Either right-click maryjanecoin-qt → Open (then confirm), or strip the quarantine attribute:

   xattr -dr com.apple.quarantine ~/Downloads/maryjanecoin-<version>/

3. Launch the GUI

   ./maryjanecoin-qt

   Config + data dir: ~/Library/Application Support/MaryJaneCoin/. Move the app bundle to /Applications/ if you want a tidy Launchpad entry.

Install on Linux (x86_64 or ARM)

1. Extract

   tar -xzf maryjanecoin-<version>-x86_64-linux-gnu.tar.gz
   cd maryjanecoin-<version>

2. Run the GUI (or install system-wide)

   # run directly
   ./bin/maryjanecoin-qt
   
   # or install
   sudo install -m 0755 -o root -g root -t /usr/local/bin bin/*
   maryjanecoin-qt

3. Headless? Use maryjanecoind + maryjanecoin-cli

   # start the daemon in background
   maryjanecoind -daemon
   
   # check sync progress
   maryjanecoin-cli getblockchaininfo | jq '.blocks,.headers,.verificationprogress'
   
   # stop cleanly
   maryjanecoin-cli stop

Raspberry Pi: the aarch64 build runs on 64-bit Raspberry Pi OS on Pi 4 or Pi 5. 32-bit installs use the armhf tarball. Either way, give the daemon 2+ GB RAM headroom and prefer an SSD over SD card for the chain data — initial sync on microSD is painful.

First-run checklist

1. Create & encrypt your wallet

   GUI: Settings → Encrypt Wallet. Pick a strong passphrase; write it down on paper and store it somewhere fireproof. Losing it means losing your coins — there is no reset.

   CLI:

   maryjanecoin-cli encryptwallet "my-strong-passphrase"
   # wallet is now locked until you unlockwallet
   maryjanecoin-cli walletpassphrase "my-strong-passphrase" 600

2. Back up wallet.dat

   Your wallet lives in a single file inside the data directory. Close the wallet before copying — the file should be copied at rest, not during a write.

   # Windows:  %APPDATA%\MaryJaneCoin\wallets\wallet.dat
   # macOS:    ~/Library/Application Support/MaryJaneCoin/wallets/wallet.dat
   # Linux:    ~/.maryjanecoin/wallets/wallet.dat

   GUI equivalent: File → Backup Wallet…

3. Wait for first sync

   The client downloads and validates every block back to genesis. On an SSD this takes under an hour; on a Pi over microSD it can take a day. The sync indicator in the bottom-right shows progress.

4. Generate a receiving address

   GUI: Receive → Create new receiving address. CLI: maryjanecoin-cli getnewaddress. MaryJaneCoin addresses start with a capital M.

Privacy features (enforced at consensus)

MaryJaneCoin's desktop wallet is where consensus-enforced privacy actually runs. Unlike toggle-optional privacy coins, MaryJ requires privacy-preserving structure on every spend after the activation heights:

Optional — maryjanecoin.conf

A small config file in your data directory tunes behaviour without command-line flags. The daemon reads it at startup.

# ~/.maryjanecoin/maryjanecoin.conf
# (macOS: ~/Library/Application Support/MaryJaneCoin/maryjanecoin.conf)

# RPC — only needed if you script maryjanecoin-cli or want external RPC access
server=1
rpcuser=rpcuser
rpcpassword=<choose-a-long-random-string>
rpcallowip=127.0.0.1

# Connect to our public seed + DNS seed
addnode=seeds.maryjanecoin.net
dnsseed=1

# Staking — fee-only model (0% inflation). Wallet must be unlocked.
staking=1

# Tor (strongly recommended for privacy)
proxy=127.0.0.1:9050
listen=0
onlynet=onion
# bind a hidden service after installing Tor — see tutorials/tor.html

# Privacy enforcement — these are consensus rules after the activation heights,
# but you can verify your wallet is respecting them via:
#   maryjanecoin-cli getwalletinfo | grep -E 'stealth|ring|shielded'

Staking from the desktop wallet

MaryJaneCoin is pure fee-only Proof-of-Stake. Validators don't earn inflation rewards (0% chain inflation) — they earn the transaction fees paid by users they include in their blocks. Any transparent UTXO older than the minimum stake age is eligible. To stake:

1. Keep the wallet unlocked for staking only. GUI: Settings → Unlock Wallet → Unlock for staking only. CLI: maryjanecoin-cli walletpassphrase "passphrase" 0 true.
2. Only UTXOs in the transparent pool can stake (two-pool rule). If your coins are in the shielded pool, peg-out first.
3. Leave the client running. Kernels are tested each second — more coin-age, more blocks.
4. Fees collected appear as generated, immature until they mature.

See the staking deep-dive for kernel math + how to optimise UTXO sizes.

maryjanecoin-cli getpeerinfo
maryjanecoin-cli getnetworkinfo

# bridge to Solana (moves mainchain MARYJ to SPL MARYJ via escrow)
maryjanecoin-cli bridgetosol <solana_addr> <amount>

# shut down cleanly (always do this before backing up wallet.dat)
maryjanecoin-cli stop

Safety rules

• Write the passphrase on paper. Digital copies get lost, phished, or ransomware-encrypted. Paper survives.
• Back up wallet.dat often. Each new address uses keys from the internal pool; backups lag behind if you keep creating addresses without refreshing.
• Never share wallet.dat or debug.log. The wallet is the coins. Debug log can leak addresses.
• Verify SHA-256 before installing once builds exist. If the download is tampered with, the hash won't match.
• Consider a paper wallet for long-term storage. See the paper wallet guide — key generation offline, spending keys never touch a networked machine.
• Run over Tor if you can. Network-layer privacy complements the consensus-layer privacy. See the Tor guide.

Next steps

• Staking deep-dive — fee-only PoS mechanics + kernel math
• Bridge MARYJ ↔ Solana — use bridgetosol to move coins to SPL
• Stealth addresses + ring mixing + two-pool — the privacy primitives the wallet enforces
• Paper wallet — cold storage generator
• Tor config — run the daemon over an onion service
