    From Bitcoin to Sifchain – The Evolution of Blockchain


    It has been virtually fourteen years since Bitcoin launched the world to blockchain expertise. Its whitepaper offered the blockchain as a substitute to peer-to-peer funds. Since then, blockchain expertise has grown into one thing with the potential for way more. 

    Blockchains use a mixture of completely different applied sciences to course of transactions and retailer information. These embrace cryptography, recreation principle modeling, and peer-to-peer networks. Cryptography entails encoding and decoding information, whereas recreation principle makes use of mathematical fashions to research strategic resolution-making. On the opposite hand, peer-to-peer networks enable for transactions with out the necessity for an middleman. 

    These applied sciences work collectively to create a trustless system for transactions. It is safe, clear, and decentralized, just like the Bitcoin whitepaper envisioned. And, as blockchain adoption will increase, they’ve had to evolve to meet the rising wants of customers. This has led to the event of completely different blockchain applied sciences.

    Generally, blockchain expertise might be damaged down into layers 0, 1, and a couple of. Each layer contributes completely different performance to the ecosystem. This might be by offering fundamental safety, scalability, interoperability, growth, and different features.

    But what precisely do these layers imply and the way do they tie into the evolution of blockchain expertise?

    Understanding the Layers of Blockchain Technology  

    Layer 0

    A Layer 0 protocol is the foundational aspect of blockchain expertise. Think of it as a framework that complete blockchains might be constructed upon. It comprises the bodily community infrastructure that kinds the premise of a blockchain ecosystem.

    As a consequence, Layer 0 implementation protocols are sometimes seen as a “blockchain of blockchains.” Examples embrace Cosmos and Polkadot

    Ultimately, Layer 0 infrastructure holds the important thing to cross-chain interoperability. Blockchains comparable to Bitcoin and Ethereum have little to no skill to talk with each other. However, Cosmos and Polkadot present a platform that blockchains might be constructed upon so as to facilitate this cross-chain communication.

    Layer 1

    Blockchain applied sciences come to life at Layer 1. Here, you’ll discover the programming languages, consensus mechanism, dispute decision, block time, and the parameters that keep a blockchain’s performance. Therefore, it’s also referred to as the implementation layer. 

    The most properly-recognized Layer 1 blockchains are Bitcoin and Ethereum.

    Bitcoin to Ethereum

    The Bitcoin white paper launched an answer that might decentralize monetary transactions. This fashioned the premise of the Bitcoin blockchain. The chain was designed to take away intermediaries in favor of trustless, peer-to-peer transactions. That method, transactions can be cheaper and sooner.

    This fashioned the primary technology of blockchains. It was (and nonetheless is) all about monetary autonomy. Bitcoin’s objective is to set up a decentralized fee community that operates outdoors the management of any group or authorities. 

    As the expertise grew to become in style, individuals realized it may very well be used for way more than peer-to-peer monetary transactions. This impressed the creation of one other Layer 1 blockchain: Ethereum. 

    The Ethereum chain, like Bitcoin, is all about making a decentralized monetary system. However, its founders added to the Ethereum chain the power to write contracts in code. Smart contracts are self-executing contracts that facilitate peer-to-peer transactions and permit for added performance, comparable to decentralized buying and selling, lending/borrowing, and myriad different capabilities.

    Ethereum’s expertise may very well be seen as a foundational piece behind the second technology of blockchains. However, it’s constrained by the weaknesses inherent with Layer 1 blockchains.

    The drawback with Layer 1 Blockchains

    Layer 1 blockchains usually have points with scalability and/or interoperability.  Scalability refers to a blockchain’s skill to deal with extra transactions as demand arises whereas interoperability is the power to enable for cross-chain communication.

    Bitcoin and Ethereum usually are not precisely scalable. Ideally, these blockchains ought to help hundreds of transactions per second, permitting them to comfortably cope with community congestion. But Bitcoin can solely carry out 7-10 transactions per second, and Ethereum achieves round 30 per second. 

    The sluggish velocity is as a result of each chains use the Proof-of-work (PoW) consensus mechanism. PoW requires computer systems to clear up advanced mathematical puzzles, which take time and computational energy.  So, when too many transactions are being written on the Bitcoin and Ethereum blockchains, the networks grow to be congested, inflicting delays and dear transactions.

    Therefore, these chains have problem competing with present fee processing programs. Take Visa and Mastercard as examples. These help hundreds of transactions per second and the transaction price by no means spikes, even when there are numerous transactions being written on their programs.  

    One method to clear up this drawback is by scaling Layer 1 blockchains. This entails rising the quantity of nodes. The extra nodes there are within the ecosystem, the sooner and cheaper transactions grow to be. However, this transfer comes with its personal set of issues, generally referred to because the blockchain trilemma. 

    The blockchain trilemma is the idea {that a} chain should prioritize two of the three blockchain parts: decentralization, safety, and scalability. This prioritization comes on the expense of the remaining profit. 

    For instance, Bitcoin and Ethereum provide excessive ranges of safety and decentralization on the price of scalability. Solana and BNB, however, prioritize scalability and safety, however are extremely centralized. 

    In Bitcoin’s and Ethereum’s case, modifications made to enhance scalability, would trigger decentralization and safety to undergo. Therefore, an answer that doesn’t modify the blockchain community is required. That answer comes within the kind of layer 2 scaling.

    There can be the issue of poor interoperability. Current Layer 1 blockchains exist as their very own separate ecosystems. Therefore, they’re restricted to transacting inside themselves. This is one of the largest obstacles to the development of DeFi as a substitute to conventional finance. 

    Sifchain’s Solution to the Lack of Interoperability

    Sifchain is a layer 1 blockchain venture. It has capitalized on Layer 0 interoperability to develop new cross-chain options. By doing this, it has been ready to create a multi-chain decentralized trade permitting its customers to trade and switch cryptocurrency between a quantity of completely different blockchains inside the Cosmos ecosystem. 

    The venture staff constructed the primary, and just for fairly a while, Cosmos to Ethereum bridge. Not solely that, however the venture has additionally launched plans for a characteristic known as “Omni-EVM” that can develop its capabilities to a variety of Ethereum Virtual Machine (EVM) blockchains as properly.

    Additionally, Cardano’s current growth in the direction of EVM compatibility has opened further doorways for Sifchain. The venture has utilized for a grant from the Cardano Project Catalyst to construct its subsequent bridge, and join the Cardano and Cosmos ecosystems.

    Layer 2

    Layer 2 blockchains had been created as options to layer 1 scalability subject. These options take many kinds, like rollups, sidechains, state channels, nested blockchains, and extra. Generally, all of them contain constructing a blockchain expertise answer on high/alongside an present Layer 1 protocol. 

    This supplies an avenue the place transactions and processes can happen independently of the primary (layer 1) chain. This significantly improves the scalability with out altering the primary chain’s infrastructure, therefore avoiding the blockchain trilemma. 

    Well-known examples of Layer 2 networks embrace Polygon and Arbitrum, that are constructed on Ethereum. Polygon can help up to 65k transactions per second. This is 2,000 instances sooner than what the Ethereum blockchain gives. There can be the Lightning Network, which is constructed on Bitcoin. It processes up to one million transactions per second. 

    Unfortunately, many Layer 2s fall sufferer to some of the identical points as Layer 1s, together with interoperability. While these blockchains provide an answer to the blockchain trilemma, they’re extremely reliant on bridges and different third social gathering options when customers need to transfer funds throughout chains.

    What’s Next? Cross-Chain options

    Blockchain expertise has come a great distance and is in a continuing state of evolution. However, present blockchain ecosystems are remoted from each other. This siloed structure is holding again the blockchain business and it makes conducting transactions between chains cumbersome and insecure. 

    The subsequent evolutionary step will probably be to enhance interoperability. Fortunately, tasks comparable to Cosmos and Polkadot are pioneering this subsequent step so a frictionless cross-chain answer could be across the nook.
