  Scaling Issue with Bitcoin/BTC and Ethereum/ETH As more people use both blockchains over time, scalability issues in the Ethereum and Bitcoin core networks arise. While Visa and Mastercard's traditional payment systems can process 24,000 transactions per second, ETH networks can only process 30 transactions per second. Both networks' transaction fees rise as block demand exceeds their capacity. BitCoin($BTC) median transaction size is between 3.3 and 7 transactions per second So here is Polkadot that somehow solves the limitation of this blockchain. What is Polkadot(DOT)? Polkadot is a protocol that links incompatible networks (Bitcoin and Ethereum, for example) blockchains, enabling the transfer of wealth and data. It is also intended to be quick and scalable. The DOT token is used for governance and staking. As the ecosystem of specialized blockchains known as parachains expands, Polkadot unifies and secures them. The foundation of a truly interoperable decentralized web i...

  What is blockchain? A blockchain is a distributed database that maintains a continuously expanding list of ordered entries, called blocks, and these blocks are linked using cryptography. A timestamp, transaction information, and a cryptographic hash of the previous block are included in each block. A blockchain is a decentralized, distributed, and public digital ledger that is used for logging transactions across numerous computers in a way that prevents changes to the record from being made in the past without also changing all blocks that come after them and getting network consensus. Advantages of using blockchain : It provides greater trust among users.  It provides greater security among data.  Reduce the cost of production.  Improve Speed.  Invocation and tokenization. It provides immutable records.  Smart contracts Types of Blockchain Disadvantages of using blockchain : It is not possible to modify data. It requires large storage for a large databa...

 Error: Cannot assign value "$event" to template variable "emailBody". Template variables are read-only. First of all, binding ngModel to your local variable X from.ts is not possible using #emailBody="ngModel." A new template variable emailBody will be bound to the instance of the Angular directive ngModel, which has nothing to do with your.ts variable. The only place a template variable may be found is in your component's.html (unless you use @ViewChild or a similar method to retrieve a reference in your.ts). Here is old cod that has this issue :   < div class = "ed_contact_form ed_toppadder60 row m-0" >         < div class = "col-lg-6 col-md-6 col-sm-12" >           < div class = "form-group" >             < input type = "text" id = "uname" class = "form-control"                          placeholder...
