Gavin Wood’s speech highlights

In his keynote speech, Gavin Wood outlined the proposed changes for Polkadot 2.0, focusing on the dynamic procurement of “cores” and a paradigm shift in Polkadot’s architecture. Wood explained that the current lease model for cores would be replaced with a system of selling “core time.” This approach offers developers increased flexibility through two types of sales: bulk and instantaneous.

The monthly sale of “core time” enables developers to scale block space as needed, while the “pay as needed” option allows for on-demand access to resources. This newfound flexibility has the potential to unlock innovation, increase capacity, and improve resource management within the Polkadot ecosystem.

Gavin emphasized the agility of this approach, as market demand will determine the details, reducing the potential for long-term design flaws. Furthermore, the new model could potentially increase the liquidity of DOT tokens by reducing lockup periods, although specific details are yet to be determined.

The introduction of “bulk core time” marks a significant milestone, as block space is finally being traded as a true commodity, accessible and utilized as needed without the burden of managing a large chain. This innovation levels the playing field for new teams by reducing barriers to entry and fostering innovation. The proposed changes hold the promise of transforming DOT into more than just another token; it becomes a gateway for the massive influx of Web2 businesses into Web3.

New developments and updates

Gavin Wood’s keynote speech at Polkadot Decoded showcased several groundbreaking developments and updates that are set to shape the future of Polkadot. These include:

  • Core rental: Introducing the concept of renting computing resources to increase computational power within the network
  • Accords: Voluntary treaties across multiple chains that guarantee the faithful execution of agreed logic, offering a decentralized framework for managing digital assets and agreements, and providing a robust foundation for decentralized applications.
  • Project CAPI: Serves as an app-centric middleware facilitating the development of Polkadot-based applications that can seamlessly operate across multiple chains through the connection of multiple light client instances.
  • Hermit Relay: Enables the transfer of all user-level functionality, including balances, staking, governance, and identity, to system chains, while the concept of core rental allows Polkadot functionality to extend across multiple parachains, thereby liberating the Relay-chain. These developments aim to create a resilient application platform and contribute to building a resilient world.
  • Light Clients: Lightweight software components that enable users to connect to blockchains without the need to download the entire blockchain, improving accessibility and usability, emphasizing due to the vulnerability of centralized RPCs and the prevalence of RPC usage
  • Smoldot: An alternative lightweight Substrate and Polkadot client.
  • ZK Primitives: The development of ZK Primitives focuses on simplifying the creation of a library of advanced and high-performance zero-knowledge (ZK) primitives. The initial implementation of ZK Primitives is nearing completion, offering privacy features for on-chain collectives, including Fellowship
  • Sassafras Consensus: A new forkless block-production consensus algorithm, bringing several improvements to the Polkadot network compared to the present BABE and Aura. It enhances security and randomness, enables high-performance transaction routing, improves parachain performance and user experience, minimizes MEV (Miner Extractable Value) concerns, and prevents front-running through encrypted transactions.
  • Internode Mixnet: A network infrastructure that provides a shielded transport mechanism for short messages within the Polkadot ecosystem. It prevents the leakage of IP information associated with transactions and serves as a general messaging system facilitating communication between users, chains, and OCWs (Off-Chain Workers).
  • Human Decentralization: The distribution of power and decision-making authority among individuals within decentralized systems, promoting a more inclusive and democratic network

Integrations and partnerships

Polkadot Decoded also witnessed the announcement of several exciting integrations and partnerships, highlighting the platform’s growing ecosystem and collaborative efforts.
