⚠️ Cosanta Core v19.1.1 Update

A new update is now available:
👉 Cosanta Core v19.1.1

All users are strongly advised to upgrade by May 16.

🔥 Important

If the network votes for the hard fork,
older versions will stop working after May 27.

Don’t delay the update to avoid node downtime.

While the Cosanta network is waiting for the v19 vote, we are already testing v20 on testnet and have already produced 3 blocks after voting for the new version.

🚀 The Cosanta Network Is Preparing for a Major Upgrade
The Cosanta network is currently transitioning to the new core version — Cosanta Core v19.1.1.
If you operate:
a masternode
a full node
a mining pool
or any services based on Cosanta Core
you must install the update before May 16, 2026 (UTC 00:00).
Download the new version here:
Cosanta Core v19.1.1 Download
The final network transition deadline is May 26, 2026. After that date, older Core versions may stop working with the network.
What does this update bring?
This is not just another routine update. These releases represent a major modernization of the network.
v19 includes:
important security vulnerability fixes
multiple legacy code fixes
significantly faster blockchain synchronization
The Cosanta blockchain can now synchronize in approximately 1 hour without complicated console commands or manual tuning.
It is also important to understand that older Dash and Bitcoin Core versions become outdated over time and may contain inherited security issues and architectural limitations. Because of this, the Cosanta network is gradually migrating to newer and more modern core versions.
We are already preparing the next stage — v20
While the network is completing the transition to v19, we have already prepared Cosanta Core v20.1.1.
The v20 release is planned immediately after the network fully accepts the v19 upgrade.
If the network signaling process is successful, v20 is expected:
after the network reaches locked_in status
but no later than June 13, 2026
2026 Upgrade Roadmap

🚀 Cosanta: Block Reward Increased Again!

Today, the Cosanta network saw another scheduled increase in the block reward.

Each block now brings 10 COSA — the reward has increased by another 1 COSA.

But the most interesting part starts now.

From this point on, the block reward will grow much faster: every 2 days, it will increase by 5 COSA, until it reaches 50 COSA per block.

Yes, you read that right: the increase will happen every two days.

Cosanta is entering one of the most active phases of its emission schedule, and each new step makes mining, masternode operation, and network participation even more attractive.

Stay tuned - the most exciting part is just beginning.

https://cosa.is/#rewards

The next reward increase will be in 12 hours

🚀 Only 4 hours left until the next block reward increase!

In just a few hours, the block reward will increase by +5 COSA, bringing it to 35 COSA per block.

Here’s what that means:
💰 Higher rewards for everyone staking in the pool.
📈 As block rewards increase, network difficulty also rises, which means ROI gradually declines after each reward increase.

That’s exactly why the gradual reward schedule up to 50 COSA per block is so important - it helps maintain an exceptionally high ROI for a much longer period instead of peaking all at once.

⚠️ Keep in mind that actual ROI also depends heavily on pool luck. Short-term results may fluctuate above or below expectations, but over time they tend to converge toward the calculated average.

⏳ If you’ve been thinking about joining the staking pool, now is the time. The next reward increase is just around the corner, and the opportunity to benefit from these high returns won’t last forever.

Cosanta Core 22.1.3 Released

This is a mandatory update. Previous versions are no longer supported by the main network.

Key changes:

- Added support for Asset Unlock transactions and updated Platform withdrawal rules.
- Enabled encrypted BIP324/v2 P2P connections by default.
- Improved network security and resistance to network attacks.
- Improved masternode and quorum rotation performance.
- Added persistent UTXO locking that survives restarts.
- Improved responsiveness for large wallets.
- Updated platform compatibility, stability, and build tooling.

Please fully shut down the previous wallet version before updating. Note that the macOS version is now distributed as a ZIP archive.

Cosanta Core 22.1.4 Released

This is a mandatory update. Version 22.1.3 remains supported by the main network.

The new release includes the following fixes:

- Fixed excessive CPU usage caused by continuous retries of postponed PoS headers.
- Fixed a wallet UI deadlock during staking.
- Fixed getstakingstatus incorrectly reporting mnsync: false.
- Improved network reporting in getstakingstatus by checking actual peer connections.

We recommend that all users upgrade to the latest version. Please fully shut down the previous wallet version before updating.

Full release notes:
https://github.com/cosanta/cosanta-core/releases/tag/v22.1.4-cosa

50 COSA per Block. The Millionth Block Is Almost Here.

🔥 At block #999000 (Jul 14, 2026, 23:31:26 UTC), the Cosanta network officially reached its maximum block reward of 50 COSA.

This marks the completion of the three-month emission increase and the beginning of a new chapter for the network.

But the biggest milestone is still ahead.

🚀 Block #1,000,000 — DAO Activation

At block 1,000,000, Cosanta will activate its DAO (Decentralized Autonomous Organization).

Inspired by Dash’s governance model, the DAO allows masternode owners to vote on proposals that determine the future development of the network and allocate part of the block rewards to fund ecosystem growth.

Cosanta is evolving from a blockchain into a community-governed ecosystem.

📈 Maximum Emission Is Here

The network is currently creating approximately:

27,250 COSA every day.

This is the highest emission rate in Cosanta’s history.

But it won’t last forever.

⏳ In approximately three months, the circulating supply will reach around 2.45 million COSA, triggering the network’s first halving.

After the halving, the issuance rate will decrease, and as the total supply and staking participation continue to grow, ROI will gradually decline over time.

Historically, the highest returns have always belonged to early participants.

⚡ Maximum block rewards have been reached.
⚡ DAO launches at block 1,000,000.
⚡ The first halving is only a few months away.

Mandatory Cosanta Core v23.1.7 Update Released

A new version of Cosanta Core v23.1.7 has been released. This update is mandatory for all wallets, nodes, and masternodes. Previous versions are not compatible with the upgraded network.

Key changes:
• Improved the performance and security of InstantSend, ChainLocks, and quorums.
• Reduced InstantSend confirmation latency.
• Improved P2P network stability and security.
• Block header synchronization is now almost twice as fast.
• Added full support for descriptor wallets.
• Improved recovery phrase backup and wallet restoration.
• Enhanced transaction privacy and added dust attack protection.
• Updated masternode management and monitoring interfaces.
• Added new RPCs for CoinJoin, keypool management, and database diagnostics.
• Updated Qt to version 5.15.18 with security fixes.
-Fixed wallet loading, InstantSend, networking, and client stability issues.

We strongly recommend updating Cosanta Core as soon as possible.

🚀 Only 24 Hours Until the Cosanta DAO Launch!
