Block Explorer for Blockchain Transactions

There is a block explorer that allows users to view transactions on the blockchain. It is designed well. There’s a table that contains all the transactions. The block height, age, amount of tokens generated, and method of token generation is provided. The difficulty rating for each transaction is provided as well.

There’s a search bar that lets users search for transactions by various factors. Other information is displayed below the search bar including BTC price, USD price, market capitalization, known peers, difficulty rating, and the number of available tokens. There are several tabs across the table with more information including a list of the top earners and their addresses.

Proof-of-Stake Mining

OPAL is extracted through the Proof-of-Stake method. This method prevents users from mining a disproportionate amounts of blocks. This method is dependent on the amount of tokens a user holds. They will only be able to mine a certain amount of blocks (verifying transactions). This amount is dependent on the number of tokens they hold. If they hold 2% of available tokens, then they are limited to mining 2% of the blocks on the ledger.

Proof-of-Stake is an energy-efficient method of mining. The alternative verification method, Proof-of-Work, requires a lot of electricity to process a cryptocurrency transaction. This is equivalent to the amount of electricity required to power 1.57 American households for one day.

Proof-of-Stake is a secure mining method as well. Since the user has a stake in the network, it is unlikely that the user would attack the network (51% attack method). Their earnings would decline if that happened.
