- - - - Ethereum's low throughput
        Poor User Experience (UX) - Gas & Delayed PoW finality
        No sovereignty - Shared throughput/clogging risk/Tech stack not customizable/governance dependence
    - - No specialized framework to build blockchains to nor a protocol to connect the projects filling Ethereum's gaps
        
        E.g. Polkadot, Cosmos, Ethereum fork etc.
    - - A protocol or framework for building and connecting Ethereum-compatible blockchain networks
        
        One click deployment of preset blockchain networks
        
        Growing set of modules for building custom networks
        
        Modular & optional security as a service
        
        Interoperability protocol - For exchanging arbitrary messages with Ethereum & other blockchain networks
        
        Adaptor modules - Enabling interoperability for existing modules
  - - - The network is fully in-charge of their own security i.e. own pool of validators
        
        Offers highest level of independence and flexibility
        
        Trade-off: Sometimes challenging validator pool establishing
        
        Who uses this network? Enterprise, established projects with strong community
    - - Networks use security as service either from Ethereum directly (via fraud proofs or validity proofs) or by a pool of professional validators
        
        Offers high level of security
        
        Trade-off: Independence & flexibility
        
        Who uses this network? Startups, security-focussed projects
  - - - Slow transactions
        
        consensus provided by a selected set of Block producers, chose for every checkpoint by a set of Stakers
        
        PoS to validate the blocks
        
        Blocks don't need to be validated by all the nodes
        - Makes the block confirmation time extremely fast (<2s)
      - low transaction throughput
        
        Public blockchains like Bitcoin & Ethereum need to maintain a certain amt of time lag b/w production of adjacent blocks so as to ensure ample time for propogation
        
        This means block size needs to be small to ensure quick propogation, which means limited no. of transactions within a block
        
        Introducing "BLOCK PRODUCER LAYER" to produce blocks at a very fast rate. Decentralization is ensured using PoS checkpoints which are pushed to the MainChain (Ethereum)
        
        Theoreticially, allows us to achieve 2^16 TPS on a single side chain
      - scalability
        
        More sidechains to be included using the same decentralised PoS layer
      - size of blockchain
        
        nodes may choose to store the blocks from previous checkpoint to the next checkpoint
        
        all previous transaction/block proofs have been submitted to the main chain
        
        this enables extremely low fidelity PoS nodes which can be run on low cost machines & storage
        
        Future - mobile device based miners
      - multiple micropayment channels with
        other off-chain solutions
        
        any valid ethereum address is a valid Matic address
        receiver need not be on the matic chain to receive payment
        only matic wallet is needed
      - high transaction fees
        
        Enables low cost transactions through achieving economies of scale by doing a large no. of transactions on the Blockchain Producer Layer which ensures low cost
      - Poor Usability
        
        Working on various web & mobile browser integration tools and is pioneering protocols in this domain
        
        Intends to build a ubiquitous mobile/web browser app, which will act as a secured interaction layer for blockchain interactions
