Marscoin Core v28.1.0 Release

Technical Overview

The Marscoin development team has released Marscoin Core v28.1.0, a major upgrade based on the latest Bitcoin Core codebase. This is a mandatory upgrade for all node operators, miners, pools, and exchanges. Marscoin Core v28.1.0 brings the Marscoin codebase up to date with Bitcoin Core 28.x, incorporating years of upstream improvements in:

P2P networking: Improved peer discovery and connection management
Performance: Faster block validation and reduced memory usage during initial block download (IBD)
Security: Latest security patches and hardened RPC interface
Wallet: Descriptor wallets support and improved coin selection algorithms

Marscoin maintains its core consensus rules throughout this upgrade.

Fork Information

Nodes running versions prior to v28.1.0 may fork onto a stale chain. If your node shows a significantly different block height than the block explorer, you are likely on the wrong chain and need to upgrade immediately. After upgrading, if your node does not sync to the correct chain, restart with the -reindex flag:

./marscoind -daemon -reindex

Download and Installation

Download the latest release from:

https://github.com/marscoin/marscoin/releases

Linux Upgrade Steps

Stop running daemon:

./marscoin-cli stop

Backup old binary (optional):

mv marscoind marscoind.old

Download and extract new release:

wget https://github.com/marscoin/marscoin/releases/download/ee4e2a7/marscoin-linux.tgz
tar -xzf marscoin-linux.tgz

Copy new binaries:

cp marscoin-linux/marscoind .
cp marscoin-linux/marscoin-cli .

Restart:

./marscoind -daemon

Nodes with only 1 GB RAM should enable swap space to prevent out-of-memory crashes during sync.

Verifying Your Node

After upgrading, verify you’re on the correct chain:

./marscoin-cli getblockchaininfo

Check that your block height matches the explorer and that initialblockdownload is false.

Network Infrastructure

The Marscoin network is supported by globally distributed nodes:

Primary explorer and Electrum servers
Edge nodes in Singapore, Frankfurt, Sydney, San Francisco, and New York

All infrastructure has been upgraded to v28.1.0.
