This post captures my current engineering thesis across AI systems, space infrastructure, blockchain, and RF validation.

General-purpose LLMs are powerful, but when it comes to deep analysis in specialized domains, they have two hard limitations: knowledge that lags behind the cutting edge, and factual dilution for niche fields. Take the Polkadot ecosystem as an example — key 2024–2026 developments like Agile Coretime, RegionX, and JAM are either unanswerable by general models, or return outdated information.

The solution is not a bigger model — it's giving the model a structured, trustworthy external knowledge base, then wrapping it with a persona and task prompt. That's the motivation behind my myGPTs.

I first encountered Plurality while browsing documentation about Project Liberty's efforts to expand DSNP (Decentralized Social Networking Protocol) across platforms like TikTok, Bluesky, and Frequency — and I noticed that former Minister Audrey Tang was also involved.

What Is Plurality?​

I first came across Plurality because I saw Project Liberty actively advocating for breaking the traditional single decision-making model — encouraging people to approach issues from multiple angles and form governance structures that are more inclusive and adaptive. This plural perspective allows participants to explore multiple possibilities in different contexts, rather than being forced down a fixed, predetermined path. For more details, see the book Audrey Tang co-authored: Plurality GitHub Repository

Web3​

The term "Web3" was coined by Dr. Gavin Wood to refer to "a decentralized online ecosystem based on blockchain." By leveraging blockchain's inherent transparency, Polkadot implements OpenGov — on-chain governance — which interestingly shares notable similarities with the ideas in Plurality.

Polkadot's Philosophy​

Polkadot is a blockchain platform committed to cross-chain interoperability. Its core philosophy includes:

• Decentralization: Connecting multiple parachains via a Relay Chain to enable shared resources and security consensus.
• Interoperability: Enabling seamless communication between different blockchains, overcoming the limitations of isolated operation.
• Flexible upgrades: Relying on upgradeable governance mechanisms that allow the network to rapidly adapt to new requirements and challenges.

OpenGov's Philosophy​

OpenGov (Open Government) focuses on transparency, participation, and collaboration between governments and citizens. Its key characteristics are:

• Transparency: Making policy decision processes fully open to the public by publishing government data and procedures.
• Civic participation: Encouraging citizens to directly participate in public policy discussion and formulation, improving government accountability.
• Accountability tracking: Establishing robust oversight mechanisms to ensure fair distribution and use of public resources.

Comparing the Two Philosophies​

Although both Polkadot and OpenGov aim to break traditional centralized governance models, they differ in emphasis and implementation:

• Technology-driven vs. institutional reform

  • Polkadot relies on blockchain technology and token mechanisms, emphasizing technical decentralization and network interoperability.
  • OpenGov focuses on institutional innovation and information transparency to facilitate interaction and collaboration between government and citizens.

• Governance models

  • Polkadot uses on-chain governance, allowing token holders to participate in decisions, enabling self-adjustment and upgrades.
  • OpenGov values civic participation and policy transparency, aiming to reach consensus through openness and deliberation.

• Application domains

  • Polkadot primarily serves digital assets and fintech, driving the decentralized network ecosystem.
  • OpenGov focuses on public administration and policy-making, modernizing government institutions and enabling data-driven decisions.

Closing Thoughts​

Plurality offers us a framework for plural co-governance, allowing technology and democracy to advance side by side. Whether it is Polkadot's technical innovation or OpenGov's institutional reform, both are pushing society toward a more transparent, inclusive, and decentralized future.

Polkadot JAM (Join-Accumulate Machine) is a proposed upgrade to the Polkadot network designed to replace the current Relay Chain, making its design more modular and minimalist. It combines Ethereum-style smart contract functionality with Polkadot's scalability, creating a more flexible development environment.

Key Features​

• Permissionless: Developers can deploy code and pay per resource usage, similar to Ethereum smart contracts.
• Coretime: Uses "coretime" as a compute resource metric, analogous to Ethereum's gas.
• Service architecture: Runs various services such as ChainService for handling parachains, making the network more flexible.
• Asynchronous interaction: Unlike many blockchain platforms, JAM interactions are asynchronous, improving efficiency.
• High throughput: Through multi-core computation, targets throughput of up to 850 MB/s, exceeding platforms like Ethereum and Solana.

Technology and Outlook​

JAM's computation model is based on the "Join-Accumulate" mechanism, where "Join" and "Accumulate" functions execute on-chain, while "Collect" and "Refine" processes complete off-chain. This design reduces on-chain computation overhead and improves efficiency. According to the Polkadot Wiki, JAM will be a domain-specific chain focused on processing rollups and providing strong security guarantees.

Additionally, JAM supports asynchronous interaction — unlike the synchronous interactions typical of many smart contract platforms. Messages and token transfers are sent and received within the same 6-second execution epoch, but there is no immediate return path, leaving room for future performance optimizations such as allocating additional gas.

Performance Targets and Technical Implementation​

JAM's performance targets are ambitious. According to published analyses, JAM plans to use 350 JAM cores, each with a 6-second execution window and 5 MB input, yielding a combined throughput of 850 MB/s — theoretically supporting over 3.4 million TPS (transactions per second). By comparison:

• Ethereum 2.0 throughput: 1.3 MB/s
• Sui/Aptos: 100 MB/s
• Solana (post-Firedancer upgrade): 1,250 MB/s

To achieve this, JAM will use a RISC-V processor architecture, replacing the current WebAssembly-based framework. RISC-V is an open and widely adopted processor architecture already in use by companies such as Google, Nvidia, and Alibaba. This choice aims to improve computational efficiency and support multi-core parallel processing.

Test infrastructure includes:

• Polkadot Palace: A supercomputer in Lisbon, Portugal, with 12,276 cores and 16 TB RAM, capable of hosting the full JAM network.
• JAM Toaster simulator: Supports 1,023 nodes, equipped with 16,384 AMD CPUs, 32 TB RAM, and 20 PB storage.

Economics and Governance​

JAM's economic model centers on the DOT token. Developers purchase "coretime" to run computations, similar to purchasing gas on Ethereum.

JAM will also introduce Agile Coretime, a more economically flexible model that allows users to purchase coretime in bulk on a monthly basis and split or resell it on secondary markets. This improves market efficiency for compute resources, and all transactions use DOT tokens.

On the governance side, JAM retains Polkadot's decentralized leadership model — upgrades require approval through DOT holder voting. On May 28, 2024, the JAM upgrade passed with near-unanimous approval, supported by over 31 million DOT, signaling strong community endorsement of this transformation.

Current Status and Future Outlook​

JAM is currently under active development and is expected to require approximately 2 years before it is fully ready for deployment. The upgrade is planned as a single deployment rather than a phased rollout, to avoid the complexity of frequent incremental updates. Importantly, the functionality of existing parachains will not be affected, and DOT holders and traders will not experience disruption from the upgrade.

To accelerate development, the Web3 Foundation has set aside a 10 million DOT "JAM Implementer's Prize" to encourage the creation of multiple client implementations, enhancing network resilience. The establishment of this prize pool reflects the community's confidence in JAM's potential.

Impact on Developers​

For developers, JAM offers significantly greater flexibility. They no longer need to compete in auctions for parachain slots; instead, deploying a service only requires specifying three entry functions: "Refine", "Accumulate", and "onTransfer". This simplifies the development workflow and makes Polkadot easier to support for a wide range of applications including smart contracts, ZK-rollups, and UTXO models.

Security and Scalability​

JAM's security mechanism includes SAFROLE (SNARK-based block production), a zero-knowledge proof-based block production method that improves security and reduces the need for frequent updates.

At the same time, JAM's multi-core processing capability enhances Polkadot's computational power, enabling developers to deploy applications at lower cost.

Comparison and Competition​

Compared to platforms like Ethereum and Solana, JAM's high throughput and multi-core compute capabilities give it a significant performance advantage. In particular, its 850 MB/s data availability target is 42× higher than the current Polkadot (prior to introducing Asynchronous Backing). This performance improvement positions Polkadot more favorably in the blockchain scalability race.

Conclusion​

Polkadot JAM is an ambitious upgrade proposed by Gavin Wood, aimed at transforming Polkadot into a more flexible, efficient, and scalable blockchain platform. By combining Ethereum's smart contract capabilities with Polkadot's multi-chain architecture, JAM gives developers broader room for innovation while maintaining network security and decentralization.

Although full realization will take several more years, its potential has been widely recognized by the community and approved through a governance vote.

Introduction to Polkadot​

Polkadot is a blockchain platform designed to enable a multi-chain future. Rather than concentrating all Web3 use cases on a single chain, it envisions different chains (general-purpose or application-specific) working together, enabling Web3 to scale for everyday applications.

• Vision: Become the AWS of Web3.
• Goal: Build the infrastructure that any blockchain might need, in a decentralized way.

Key Features​

• Interoperability: Asset transfers via Cross-Chain Messaging (XCM) — assets are burned on the source chain and minted on the destination chain.
• Scalability: Parallel execution of different state transition functions through heterogeneous sharding.
• Flexibility: Polkadot is not static software; it is built for extensibility, flexibility, and the future.
• Governance: An on-chain democratic system where DOT holders can vote and create proposals for discussion.
• Bridging:
  • Snowbridge: A trustless bridge between Polkadot and Ethereum, using the BEEFY protocol to relay Polkadot finality to Ethereum.
  • Hyperbridge: The world's first verifiable multi-chain bridge.
  • Polkadot-Kusama Bridge: Secure and seamless asset transfers and communication.

Three Pillars of Polkadot 2.0​

  • Efficient resource use: Each chain focuses on its specific function and application, avoiding wasted compute and storage.
  • Simplified cross-chain communication: Provides a standardized approach through designed cross-chain messaging and verification mechanisms, making chain-to-chain interactions more efficient and secure.
• Polkadot's next major upgrade will adopt SASSAFRAS/SAFROLE, which uses ring VRF to solve the problem of multiple/no block producers per slot, ensuring exactly one block producer per slot.
• First version expected in July 2025.
• Separates computation into in-core and on-chain layers.
• Will allow smart contract functionality and permissionless services.
• JAM introduces a decentralized hybrid system providing smart contract functionality built around the in-core/on-chain security and scalability duality.
• JAM is inherently permissionless, allowing anyone to deploy code as a service, pay for the resources that code consumes, and direct its execution by purchasing and allocating coretime.

OpenGov​

• Polkadot's on-chain democratic system, putting power in the hands of DOT holders.
