SUMUWW Windows 0.57.21

Connection update — 16 October 2026

Public SUMUWW applications now allow up to 32 steady peer sessions, with eight outgoing opportunities reserved. These are per-node limits, not a fixed network size or a displayed target. A full listener can admit one bounded temporary connection, verify it before replacing a path, and share alternative contacts during the replacement cooldown. PC and Android use the same policy. Consensus, DGW activation at block 8,064, wallet format and network identity are unchanged.

Verification: 169 relevant PC regression tests, 16 frozen-module socket tests, packaged CLI wallet/transfer/relay smoke tests and Android emulator network tests passed. The latest recheck passed 67 PC network, language and monitor tests and replayed the active chain through block 8,143 using the SUMUWW validator. A temporary node with zero manually configured peers discovered the public network, recovered after its own connection was closed, and remained synchronized at each sample over two minutes. These results are not an independent security audit.

Real-phone installation and 5G recovery of the Android build remain unverified because the phone was disconnected. A previously tested external PC did not respond during the latest recheck; earlier success is not a claim of current availability. Source archives and SHA-256 checksums are attached.

SUMUWW — Open Connections, Greater Tomorrow.
One step. New possibilities.
Create your own wallet, send and receive coins, and take part in the blockchain network through mining.
Built on its own blockchain and independently verified by its participants, SUMUWW is a cryptocurrency shaped by the people who use it.
About SUMUWW
SUMUWW is a cryptocurrency for peer-to-peer payments, powered by Proof of Work (PoW) mining and independent validation by each node.
Validated transactions are recorded on SUMUWW’s blockchain when they are included in a block. Participants independently verify transactions and blocks using the same consensus rules.
SUMUWW aims to sustain an independent blockchain network through participant validation and consensus, without requiring individual approval from a central administrator.
Key Features
Your Own Wallet, Peer-to-Peer Payments
Create your own wallet and sign transactions with your private key. Send and receive SMW without individual approval from a central administrator. Transactions are verified by the network before being recorded on the blockchain.
Proof of Work Mining
Participants can perform Proof of Work computations on their own devices to help create new blocks. Miners who produce valid blocks receive mining rewards according to the network’s rules.
An Independent Blockchain with Node Validation
SUMUWW runs on its own blockchain. Each node independently checks a block’s Proof of Work, difficulty, rewards, transaction signatures, and balance requirements. Blocks and transactions that fail to meet the consensus rules are rejected.
A Defined Supply and Clear Rules
SUMUWW’s maximum supply is 17,999,999.9769 SMW—approximately 18 million coins.
New coins are issued through block rewards determined by block height and the halving schedule. Transaction fees are paid from existing coins and do not increase the coin supply.
Each node verifies that block rewards and transaction fee payments comply with the consensus rules.
No Special Administrative Privileges
SUMUWW’s consensus rules grant no individual—including its creator—special authority to issue coins arbitrarily, freeze or seize another user’s assets, or alter balances.
A Network You Can Verify and Participate In
Participants can examine SUMUWW’s source code and network rules to understand how it works. Anyone can use a wallet, mine, or operate a node under the same validation rules.
A Blockchain Built by Its Participants
SUMUWW aims to sustain its network through independent validation and connections between participants.
Manage your assets with your own wallet, send coins, and contribute to the network through mining and node operation.
Every participant helps build the network. Every connection opens new possibilities.

SUMUWW Explorer 0.4.0

SUMUWW Explorer 0.4.0 is a local, read-only block explorer for SUMUWW (SMW).

Downloads

• Windows 64-bit application ZIP (no Python installation required)
• Source code ZIP
• SHA-256 checksum files for both archives

Features

• Search by block height, block hash, transaction ID or SUMUWW address
• Separate mining-reward and ordinary-transfer histories, with page navigation and filters
• Transaction inputs/outputs, fees, confirmations, related transactions and local mempool statistics
• Address balances, unspent outputs, historical balances and period analysis
• Mining statistics, difficulty analysis, charts and observed block-composition comparisons
• Raw block/transaction downloads, Merkle inclusion proofs and CSV exports
• PDF transaction receipts and reports
• 33 bundled interface languages

Run

Extract the entire Windows ZIP and run start-explorer.cmd or SUMUWW-Explorer.exe. The browser opens http://127.0.0.1:8770.

A synchronized SUMUWW node database is required. The explorer reads that node's node.sqlite in read-only mode and keeps its own separate search index. For a custom path, run:

SUMUWW-Explorer.exe --database "C:\path\to\node.sqlite"

This download is a local application, not a publicly hosted website. The explorer does not run a node, synchronize the chain, mine, access wallet keys or send transactions. Statistics and confirmations describe the selected node's active chain and local mempool.

Source users: Python 3.10+ and the dependencies in requirements.txt are required.

Validation

79 isolated reader/analytics tests and 40 UI unit tests passed. Test fixtures check explorer behavior; they do not constitute an independent consensus or security audit.

Android 0.6.53-pc043 (versionCode 113). Install the signed APK over the existing app to update; do not uninstall or clear app data. The existing official signing lineage is retained. Keep a wallet backup before updating. The source archive is attached separately. Internal backend-version and documentation-version labels were aligned with the current release.
