As a blockchain developer, you’re guaranteed to be in high demand for the next decades. It used to be that blockchain developers were only needed by people who want to start their own cryptocurrency, which aren’t that many. Now that everyone is seeing the benefits,blockchain adoptionis ...
The initial excitement surrounding Bitcoin stemmed from its use as a token of value, for example as an alternative to government-issued currencies. Now the separation between Bitcoin and the underlying blockchain technology is getting better understood, the scope of the technology itself and its appl...
Why Use Blockchain Explorer? On the surface, general blockchain explorers seem to generate a myriad of confusing data when someone is relatively new to cryptocurrency. A lot of data that is provided on the screen by the Blockchain Explorer does not make sense at first, but eventually, when ...
This test blockchain provides a default test account for you to deploy and call contracts. If this test account cannot meet your requirements, you can use the account created by using the SDK. In this case, you need to enter the private key (a hexadecimal string) to sign the transactions...
Mistake:What do “experienced” blockchain marketers say after 2 months of work? You need to create a community everywhere - Facebook, Discord, Twitter, Telegram, Reddit, etc. What for? Because. Just because other projects do it. In the end, you do not have time to manage all the creat...
So the security of a blockchain comes from its creative use of hashing and the proof-of-work mechanism. But there one more way that blockchains secure themselves and that's by being distributed. Instead of using a central entity to manage the chain, blockchains use a peer-to-peer ...
One defining feature of blockchain is its transparency — every transaction is visible to all participants. While this is beneficial for some use cases, it can be a drawback for others. In response, newer blockchain platforms have developed privacy mechanisms, though these are still evolving and...
In most cryptocurrencies, anyone running the right software can help create and confirm the blockchain. The reward is some of the cryptocurrency, which is generated each time a block is confirmed. Cryptocurrency isn't the only use case for blockchain technology, and theoretically, the data stored...
Cryptocurrencyminingis commonly thought to be solving a complex mathematical problem; mining is actually sending block data through a hashing algorithm (which uses complicated math functions) to generate a hexadecimal number. For example, Bitcoin uses the hashing algorithm SHA-256. For a miner to gen...
Different types of information can be stored on a blockchain, but the most common use has been as a transaction ledger. In Bitcoin’s case, the blockchain is decentralized, so no single person or group has control—instead, all users collectively retain control. Decentralized blockchains are...
