Detailed summary
� 00:00 Polkadot has successfully implemented its concept of block space and ecosystems, which defines the work of validators and the product they create in the blockchain world.
The speaker discusses the achievements of Polkadot 1.0 and lays out a vision for the future, specifically focusing on block space and its importance.
Polkadot's concept of block space and ecosystems has become a reality, as it defines the product created by validators and the fundamental unit of their work in the blockchain world.
� 02:12 Block space in Polkadot is created by allocating resources like compute, networking, value at stake, and storage, and hybrid chains can optimize block space utilization for efficient interaction and utilization in the decentralized economy.
Block space is the decentralized security that is created by allocating raw resources like compute, networking, value at stake, and storage into units of block space, which is what we want to use to run applications in Polkadot.
Hybrid chains, which involve every blockchain running a smart contract, optimize block space utilization and allow for the benefits of asynchronous and synchronous processing on a single blockchain.
The decentralized economy's structure and efficiency will depend on the degree of coupling between different programs or applications, taking into account the costs of communication, and the concept of hybrid chains can optimize block space consumption for efficient interaction and utilization.
� 05:45 Building a builder community around projects like Polkadot allows for innovation, building out primitives and extensions, and reaching different verticals outside of the project's bubble.
Examples of projects adopting the hybrid chain approach and focusing on block space include Zeitgeist and Interlay, as it allows teams to build their developer community alongside their work easily.
The benefits of building a builder community around a project like Polkadot include the ability to innovate directly alongside the project, build out primitives and extensions, and reach different verticals outside of the project's bubble.
� 08:07 Polkadot is transitioning from a slots model to an on-demand model for block space allocation, allowing users to pay market price for block production based on their application's needs, aiming to boost throughput and cater to various use cases.
Polkadot currently uses a slots model for block space allocation, where auctions are held for guaranteed high frequency block space for a certain period of time.
Block space allocation in Polkadot is changing to introduce on-demand models, where users can pay the market price to make one block and have the flexibility to choose between infrequent or high-frequency block production based on their application's needs.
The mixed model of allocations in Polkadot aims to bring together slot-based and on-demand models to boost throughput and cater to various use cases.
Cloud business models are based on the idea of having reserved instances for predictable usage, but also being able to handle sudden bursts of high traffic.
� 11:42 Developers are attracted to Polkadot's ability to scale without paying for unnecessary block space, providing a balance between churn and stability for efficient and cost-effective blockchain projects.
The ability to scale up and boost without paying for unnecessary block space is an attractive feature for developers and allows for proper scaling at good costs, contrasting with more rigid blockchain implementations.
Most ecosystems focus on pay-as-you-go transactions, but the lack of guarantees about future prices leads to volatility and inefficiency, so a balance between churn and stability is needed for scalability, security, and good scheduling.
Allocative efficiency is crucial in scaling blockchain projects, and the goal is to achieve an on-demand model with high churn and unpredictable prices, while also providing stability, predictability, and lower costs through bulk block space allocation.
� 14:44 Polkadot's flexibility and allocation model provide a platform for innovators to go from experimentation to scaling by offering a wide range of block space capabilities, allowing teams to deploy software, incentivize collators, and access consistent block space through a proposed brokerage pair chain or secondary market.
Polkadot's flexibility and allocation model help innovators in their journey from experimentation to product market fit and scaling by providing a platform that offers a wide range of block space capabilities.
The current models are not suitable for the audience, but the speaker wants to discuss the vision and steps of deploying a product for those interested in building products, applications, or software protocols.
There are two types of audiences in the blockchain space: bootstrappers who prefer to build and scale without raising money, and those who seek funding and resources for their ideas.
Teams can deploy their software on the Polkadot Network, upload code to build on-demand chain blocks, incentivize collators to create blocks, and eventually scale by accessing consistent block space through a proposed brokerage pair chain or a secondary market.
� 18:22 Polkadot's shared security and composability are important for innovation, but copying this model may have economic implications and trade-offs; restaking across multiple applications can lower costs for users, and specific security costs are more beneficial than giving up ownership for shared security.
Polkadot's shared security model and composability are important for removing barriers to innovation, but other projects attempting to copy this model may face economic implications and trade-offs in terms of cost and acquiring shared security capabilities.
Validators in blockchain systems need to be rewarded for their work and risk, and one way to do this is by allowing users to restake their stake across multiple applications, resulting in lower costs for users.
It is more beneficial to have specific costs for security rather than giving up ownership in exchange for shared security, as seen in the example of interchange security taking token percentages from teams building on the cosmos Hub.
� 21:17 Polkadot aims to provide flexible block space for the development of a wider range of applications, with potential for customizable data storage and elastic scaling, and the possibility of implementing block space marketplaces to efficiently allocate block space to applications.
Flexibility in block space allows for the ability to write code without constraints, enabling the development of a wider range of applications in the web 3 ecosystem.
Polkadot aims to provide customizable data storage and formats, with the future potential for elastic scaling to accommodate varying levels of load on the network.
Applications on blockchains can be thought of as self-contained pieces of work that offload tasks to cores and utilize block space until they are done, changing the way we think about applications in the blockchain world.
Block space marketplaces could potentially be implemented using a design called block space regions, which allow for the ownership of future rights to block space and can be split based on time or frequency of access to a core.
Secondary markets within the Polkadot ecosystem can match buyers and sellers of block space, ensuring that the exact quantities needed by applications are allocated efficiently.
Moving from thinking about blockchains to block space, Polkadot is connecting all the Dots and sharing more information on their website.
