The fixed limit of Blockspace in a dapp platform, constraints scalability
For widespread Web3 adoption, Blockchains need to find a solution to address the constraints of limited throughput of Blockchains. We have come a long way, in Blockchain design that’s improved scalability, with Proof of Stake chains, however another factor to consider is the need for flexible Blockspace.
It is not feasible for any one Blockchain app to scale to accommodate global scale of adoption, the only way a Blockchain dapp can scale to meet the usage demands of billions of users that would onboard in future, is by borrowing more Blockspace.
When a huge inflex of users pour in to use a Blockchain dapp, there will be more demand for Blockspace, as available Blockspace of the Blockchain is utilised, leading to congestion, where users’ transactions wait in ques to be processed, and fees spiral as users who can afford to pay more fees get their transactions processed and finalised first.
Blockspace used by dapp Network for computing transactions and recording processed data
Blockspace is the fundamental offering of any Blockchain and their quality varies Blockchain to Blockchain. Blockspace is a portion of the Blockchain allotted for building a Blockchain dapp. This space is utilised to process all computation and record data.
Blockspace is utilised to process all activities in Blockchain from validation of transactions, to recording of those transactions, to storing tracking data of supply chain Blockchains, storing digital identity, storing assets, that’s Blockspace allotted to store assets giving asset ownership rights to users.
Smart contract execution in DEFI dapps utilise Blockspace, be it for asset swapping, providing liquidity to pools, lending and borrowing activities with all processed data of these activities recorded on Blockspace. All these transactions and information are recorded inside Blocks in the Blockspace.
So, Blockspace is an essential piece of infrastructure provided by a Blockchain and for Web3 applications to function seamlessly in a reliable manner, healthy Blockspace is essential.
Characteristics of Polkadot’s Blockspaces that are building blocks to build robust Web3 dapp platforms
Blockspace can be composed by individual smart contract platforms, or by Blockchain producers, which are platforms that can be used by developers to build their dapps.
This post will only talk about healthy Blockspace as offered by Polkadot Blockchain. This promises to be fascinating because Polkadot has built an infrastructure geared for mass adoption, with its quality Blockspace offerings that are ‘fit for purpose’ Blockspaces that can be assembled into a dapp based on the requirements of their Web3 business customer.
These Blockspaces are flexible, composable, secure and embedded with pre-existing functionalities, so developers can create their dapp composing their Blockspace ecosystem with Blockspaces suited for powering the various functionalities of their dapp.
Evaluating the characteristics of Polkadot’s Blockspace that make it a healthy Blockspace
Well Secured Blockspaces for building secured Web3 platforms
Polkadot Relay chain validators provide security to all the connected Parachains, so all Blockspaces of the Polkadot Network are secured by Polkadot’s Relay chain validators.
This is extremely useful for developers allowing them to create dapps out of these already secured Polkadot Blockspaces so created dapps will be secured by default and focus of developers can go on improving the functionality of the dapp.
Security means consensus process takes place correctly, and there is no room for 51% attack of the network, so valid verified transactions are only approved on Blockchain which cannot be reversed.
So, economic security of the entire ecosystem of dapps and their stability is assured.
Blockspaces that are composable with the ability to engage in complex communication
There is interoperability within the Polkadot ecosystem, with XCM (Cross-Consensus Messaging) making it possible for all parachains (dapp platforms) that’s the different Blockspaces inside them to communicate with one another and be programmed across the Network.
(This attribute of compossibility is valuable for more reasons than just for executing transactions, will come to that next point.)
Easy to build purpose fit dapps with flexible Blockspaces already having pre-build functionalities
We are familiar with rigid Blockspaces that are useful for creating dapp platforms with one kind of functionality suited for one purpose but Polkadot brings in flexible blockspaces to developers, where a dapp can be composed from Blockspaces taken from different Blockchains, with these Blockspaces having pre-built functionalities.
So, developers can build ‘purpose fit dapps’ with Blockspaces that have embed functionalities. These are flexible blockspaces, that power the dapp with functionalities they are embedded with.
This way, customer can build a dapp picking the suitable Blockspace according to the functionalities needed for the dapp.
For instance, a supply chain tracking dapp can be built from suitable blockspaces taken from different Block producers, with each Blockspace embedded with specific functionality that combines powering the dapp with suitable functionalities as required.
So, such a supply chain tracing dapp can be composed combining a Blockspace from a Blockchain producer that specializes in identity verification with another Blockspace taken from a Blockchain specializing in asset tokenisation with another Blockspace taken from a Blockchain that specializes in supply source tracing.
Since, Polkadot offers different range of Blockspaces both rigid and flexible, developers can choose the Blockspace according to the use case functionality and requirements of their dapp.
Efficient allocation of Blockspace equipping dapps with more Blockspace when required
A model that efficiently allocates Blockspace that allows for more Blockspace to be added when required for any dapp platform during times of high load, so the dapp is able to scale to tackle high usage load.
Dapp platforms should be allocated Blockspace that syncs with the platforms usage, be it low, average or high. So, that Blockspace remains affordable to acquire and more can be added according to need.
In Polkadot, Parachains acquire Blockspace in bulk via Parachain Crowdloans where they rent Blockspace for a period of time. Additional, Blockspace can be purchased on demand with parathreads. This feature is coming up on Polkadot.
Cost-efficient Blockspace that’s purchased based on general usage patterns of dapp
Developer teams should be able to purchase Blockspace according their platform’s general usage requirements based on demand, while as mentioned having the option to add additional Blockspace when needed.
So, there is no cost barrier for developers to start building innovative dapps and experiment on Polkadot.
Polkadot’s infrastructure is tuned to facilitate large scale adoption of Web3!!
Overall, Polkadot Network provides infrastructure for Blockchain ecosystems to be created where all individual Blockchain producers(parachains) are interconnected and secured, and their Blockspaces can be utilised to build purpose fit dapps.
There will be a mechanism, that allows for dapps to scale as more Blockspace can be borrowed when a dapp platform finds its available Blockspace overloaded, and insufficient to process more user transactions.
This is the kind of infrastructure needed for facilitating wide spread adoption of Web3 technology, where dapps can scale to accommodate any amount of demand, while dapps with needed functions can easily be build cost effectively.
This benefits developers, as they got robust infrastructure to build dapps with innovative use cases, business clients who can get Web3 platforms offering various services for their customers and users ofcourse who can enter the world of Web3, owning their assets, having control over their data.
