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 this APK 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.

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.

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 peer-to-peer cryptocurrency powered by Proof of Work (PoW) mining and independent validation by each node.

Validated transactions are recorded on SUMUWW’s own blockchain once they are included in a block. Participants follow the same consensus rules to verify transactions and blocks for themselves.

SUMUWW aims to sustain an independent blockchain network through participant validation and consensus, without requiring individual approval from a central administrator.

Key Features

Your Wallet, Your Transactions

Create your own wallet and sign transactions using 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

Use your device to perform Proof of Work calculations and participate in creating new blocks. Miners who produce valid blocks receive rewards according to the network’s rules.

An Independent Blockchain with Node Validation

SUMUWW runs on its own blockchain. Each node independently checks Proof of Work, difficulty, block 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 has a maximum supply of 17,999,999.9769 SMW—approximately 18 million coins.

New coins are issued according to block rewards and a halving schedule determined by block height. Transaction fees are paid from existing coins and do not increase the 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.
