A New Era for Pastel Network: The Vermeer Mainnet Release

As blockchain and Web3 technologies continue to advance, we are excited to introduce Vermeer Mainnet Release 2.1, a pioneering upgrade setting new standards in the industry.

This update introduces a suite of enhancements designed to fortify the network’s infrastructure, streamline operations, and significantly advance its commitment to security and decentralization. With revolutionary changes to the consensus mechanism, upgrades to the Pastel Node software, and improvements across Supernode & Walletnode functionality, this release marks a significant milestone in Pastel’s journey.

Let’s delve into how this update redefines & impacts the Pastel ecosystem.

Important Notes:

  • The latest Protocol Version 5 release will activate at the Pastel Network Block Height of 649,000, or approx. March 15th, 2024 at 07:35:00 EST/11:35:00 UTC. After this Block Height, prior client versions will no longer be supported and all newly mined blocks will be signed using the PastelID of an active Supernode via mining pools.
  • As this update includes a major change to our consensus mechanism and CB transactions, we are taking the necessary precautions to ensure a secure and safe update for partners. All custodial partners (such as Centralized Exchanges or Staking Providers) are strongly requested to halt withdrawals / deposits of PSL starting on March 15th, 2024 09:00:00 UTC and until network stability is ensured.
  • At the Pastel Network Block Height of 650,152, or approx. March 17th, 2024 at 07:35:00 EST/11:35:00 UTC, newly mined blocks may be signed by active Supernodes via solo mining in addition to pools.

Key Vermeer 2.1 Updates and Their Benefits

  • A Leap in Blockchain Consensus: Vermeer 2.1 revolutionizes Pastel’s mining system by introducing Supernode-exclusive mining. This strategic move not only bolsters network security but also promotes a more decentralized mining landscape. By aligning mining incentives with the network’s longevity, this upgrade promises to enhance token economics and network health substantially.
  • Enhanced Node Software: The Pastel Node software sees substantial improvements, including new RPC endpoints and security enhancements. These upgrades improve network functionality, efficiency, and security, ensuring a smoother and more reliable experience for all network participants.
  • Supernode and Walletnode Evolution: The introduction of self-healing functionality within the storage layer is a testament to Pastel’s innovative edge. This feature significantly reduces the risk of data loss, ensuring the network’s resilience. Enhanced communication protocols between Supernode and Walletnode streamline operations, further elevating the network’s performance.
  • Gateway Enhancements for User Accessibility: Vermeer 2.1 enhances the Pastel Gateway, making it more user-friendly and accessible. These improvements facilitate smoother integrations and interactions within the network, enriching the overall user experience.
  • Diverse Library Updates for Increased Network Activity: The addition of new libraries and updates to existing ones underscores Pastel’s commitment to accessibility and network engagement. These enhancements are pivotal in fostering a vibrant and active ecosystem.

Further details on each key update are provided below.

Revolutionizing Consensus with Supernode-Exclusive Mining

The centerpiece of Pastel’s Vermeer 2.1 upgrade is the overhaul of its consensus mechanism, specifically through the introduction of supernode-exclusive mining. Initiated by Pastel Network Improvement Proposal (PNIP) 2, this innovation targets the elimination of the PSL free-rider issue, directly linking mining incentives with the network’s enduring prosperity. This significant shift promises to substantially bolster the token’s economics, enhance network health, and secure its future success.

By confining mining activities to Pastel Supernodes (SNs), the upgrade enforces a model where only those with active SNs and substantial staked collateral can mine. This system is designed to mitigate market pressure from non-committed miners and enhance both network security and decentralization through Proof-of-Stake (PoS), while maintaining a competitive and fair environment for mining participants and the security benefits that come from Proof-of-Work (PoW).


The upgrade addresses the setbacks of the existing Proof-of-Work (PoW) system, which placed economic strain on the network by enabling miners without a long-term vested interest to participate. This has hindered the PSL’s market performance and the network’s development. The new system aims to enhance PSL’s market stability and enhance these issues by limiting mining capabilities to committed network participants, thereby reducing the negative impact of speculative mining and ensuring a more stable economic environment for PSL.


  • Mining Eligibility: Only Pastel SNs with a locked collateral of 5 million PSL and running the required node software version can participate in mining.
  • New Block Header Fields: Two new fields are introduced in the block header for “Version 5” blocks: i) the PastelID of the mining SN and ii) a signature of the previous block’s Merkle root by the SN’s PastelID.
  • Supernode Validator API: A new Python-based API server, mining_block_supernode_validator, facilitates the signing process, ensuring SNs can securely contribute to block validation without exposing private keys.
  • Mining Pool Modifications: Updates to the S-Nomp mining pool software and the Stratum Pool library accommodate the new system, requiring miners to provide SN signature data for block submissions.
  • Default CPU Mining: As a backup to mining pools, we introduce CPU mining via SNs. To facilitate these changes, various dependent libraries have been updated.
  • Dynamic Fee Adjustment: Mining fees adjust based on network hash rate changes, maintaining service affordability and incentivizing hash rate growth in proportion to PSL value.
