Deep Dive
1. Elastic Scaling & JAM Protocol (August 2025)
Overview: Elastic Scaling allows Polkadot parachains to dynamically add/remove computing cores based on demand, while JAM transforms the network into a programmable blockchain supercomputer.
Polkadot now enables projects to scale resources on-the-fly, avoiding fixed infrastructure costs. During stress tests, Kusama (Polkadot’s canary network) processed 143,000 TPS using just 23% of its capacity. JAM introduces a modular framework supporting native rollups and advanced compute use cases like AI-driven dApps.
What this means: This is bullish for Polkadot because it positions the network to handle enterprise-grade workloads (e.g., gaming, DeFi) while maintaining low fees. Developers gain flexibility to optimize costs without sacrificing performance. (Source)
2. Native Smart Contracts (December 2025)
Overview: Polkadot will natively support EVM and PVM (Polkadot Virtual Machine) smart contracts, enabling developers to deploy Solidity code or leverage next-gen execution environments.
The EVM backend ensures compatibility with Ethereum tools like MetaMask, while PVM offers faster finality and custom runtime logic. Kusama’s testnet rollout begins in October 2025, with Polkadot mainnet integration slated for December.
What this means: This is neutral-to-bullish for Polkadot. While it expands developer options, adoption depends on whether teams migrate from Ethereum. Metrics to watch: parachain activity post-launch and cross-chain liquidity inflows. (Source)
Overview: The new Offline API lets developers sign transactions without live network connections, while metadata caching reduces client initialization bandwidth by ~500 KiB.
These updates address critical pain points for light clients and dApps operating in low-connectivity environments. The team also added Typed Codecs for direct access to chain-specific data structures.
What this means: This is bullish for Polkadot because it lowers barriers for builders in emerging markets and improves user experience for wallet integrations. Reduced latency could attract more institutional validators. (Source)
Conclusion
Polkadot’s codebase updates emphasize scalability (Elastic Scaling), developer flexibility (EVM/PVM), and infrastructure efficiency (Offline API). With JAM positioning the network as a blockchain “supercomputer,” the ecosystem is primed for high-complexity dApps. However, success hinges on parachain adoption and cross-chain interoperability.
What’s next? Will Polkadot’s throughput upgrades translate to measurable TVL growth in DeFi protocols like Hydration and Bifrost?
