Blockchain
Blockchain is one of the most advanced technologies
today. It is a system that records information in a customized way so that it
prevents any kind of fishing activities from outside. It primarily refers to a digital
ledger of transactions that are subject to distribution through an entire
network of computer systems on blockchain technology.
Every blockchain
involves multiple transactions. Note that every new structure happens on the
blockchain. However, a decentralized database operated by multiple candidates
is called DLT or distributed ledger technology. Blockchain refers to a type of
DLT that records each transaction with a HASH (an immutable cryptographic
signature).
Blockchain technology
is a digital system of record that records, stores and integrates transactions
without the need for a third party. Blockchain technology creates
"blocks" of transactions, which are then linked and secured using
cryptography. Blocks are linked to each other and secured using the
cryptographic hash of the previous block.
1. Bitcoin Blockchain
Blockchain is a
distributed, public ledger that contains the history of every bitcoin
transaction. Anyone can download a copy of the blockchain, and it can be
inspected to trace the path of bitcoins from one bitcoin transaction to
another. It should be noted that there is a record of every Bitcoin
transaction, but these transactions are not inherently linked to real-life
identities. For this reason, Bitcoin is considered a pseudonym (Anonymous).
Bitcoins themselves are
not files stored on your computer's hard drive like MP3s or PDFs. Rather,
"owning bitcoins" means owning a bitcoin address, the balance of
which is recorded on the blockchain. To own a Bitcoin address means to control
the corresponding private key, and therefore to be authorized to sign
transactions.
2.
Ethereum
Ethereum is a
decentralized blockchain platform that establishes a peer-to-peer network that
securely executes and verifies application code, called smart contracts. Smart
contracts allow participants to transact with each other without a trusted
central authority. Transaction records are immutable, verifiable, and securely
distributed across the network, giving participants full ownership and
visibility into transaction data. Transactions are sent and received from
user-created Ethereum accounts. The sender must sign the transaction and spend
Ether, Ethereum's native cryptocurrency, as the cost of processing the
transaction on the network.
Ethereum offers a highly
flexible platform on which to develop decentralized applications using the
native Solidity scripting language and the Ethereum Virtual Machine.
Decentralized application developers who deploy smart contracts on Ethereum
benefit from a rich ecosystem of developer tooling and established best
practices that come with the maturity of the protocol. This maturity also
extends to the quality of the user experience for the average user of Ethereum
applications, with Metamask, Argent, Rainbow and more offering simpler interfaces
with the Ethereum blockchain and the smart contracts deployed there, can be interacted with. Ethereum's large user base encourages
developers to deploy their applications on the network, further strengthening
Ethereum as the primary home for decentralized applications such as DeFi and
NFTs. In the future, the backwards-compatible Ethereum 2.0 protocol, currently
under development, will provide a more scalable network for building
decentralized applications that require higher transaction throughput.
3. Solana
Solana is a
public blockchain platform with smart contract functionality. Solana is a
highly active open-source project that implements a new, permissionless and
fast Layer 1 blockchain. Created in 2017 by Anatoly Yakovenko, a former Qualcomm
executive, Solana aims to exceed the throughput typically achieved by popular
blockchains while keeping costs down. Solana has implemented an innovative
hybrid consensus model that combines a unique Proof-of-History (PoH) algorithm
with a lightning-fast synchronization engine, a version of Proof-of-Stake
(PoS). Because of this, the Solana network can theoretically process 710,000
transactions per second (TPS) without the need for a scaling solution.
Solana's
third-generation blockchain architecture is designed to facilitate smart
contracts and decentralized application (DApp) creation. The project supports
decentralized finance (DeFi) platforms as well as non-fungible token (NFT)
markets.
Solana
Blockchain was launched during the initial coin offering (ICO) boom of 2017.
The project's internal testnet was released in 2018, followed by multiple
testnet phases leading to the eventual official launch of the main network in
2020.
4. Cardano
Cardano's
founder, Charles Hoskinson, was one of the original developers of Ethereum.
Even as they have peaked in the past few years, most cryptocurrencies have had
a chaotic growth trajectory. The scandals, hacks, and disagreements that
resulted in hard forks have brought a bad rep for their ecosystem.
Cardano
is a blockchain project founded by Charles Hoskinson, to "provide a more
balanced and sustainable ecosystem" for cryptocurrencies. According to its
website, ADA is the only coin with a "scientific philosophy and
research-based approach." In practical terms, this means that its
open-source blockchain undergoes a rigorous peer-review process by scientists
and programmers from academia.
The
non-profit foundation that runs Cardano has also partnered with a group of
academic institutions to research and evaluate all aspects of its blockchain.
For example, researchers at Lancaster University are developing a
"reference treasury model" to find a sustainable way to fund future
development for Cardano's blockchain.
ADA
calls itself the first third-generation cryptocurrency and aims to address the
scaling and infrastructure issues that first arose in Bitcoin, the
first-generation cryptocurrency that introduced the idea of digital coins,
and Ethereum, a
second-generation cryptocurrency with expanded use cases. Smart Contract Coins
In particular, Cardano aims to solve issues related to scalability,
interoperability, and sustainability on cryptocurrency platforms.
5. Avalanche
Avalanche is a blockchain
platform that aims to solve the blockchain trilemma of scalability, security
and decentralization thanks to its unique proof-of-stake (PoS) mechanism. Like
Ethereum, Avalanche supports smart contracts to run decentralized applications
(DApps) on its network. Because Avalanche's smart contracts are written in the
Solidity language, which is also used by Ethereum, it aims to create more
blockchains by integrating multiple decentralized finance (DeFi) ecosystems,
including the likes of Aave and Curve, well established projects.
AVAX, the native token of
the Avalanche platform, is used to power transactions in its ecosystem. AVAX
acts as a means of facilitating transactions on the network by distributing
system rewards, participating in governance and paying fees.
Although Avalanche's
platform is complex, there are three main aspects of its design that
distinguish it from other blockchain projects: its consensus mechanism, its
inclusion of subnetworks and its use of multiple built-in blockchains.
