Is Bitcoin Ready for the Mainstream? How Rootstock is Paving the Way

Will bitcoin ever become a mainstream payment system?

This is a question I've been struggling with recently. I don’t think anyone is disputing this, but Bitcoin has changed the world. Since the Bitcoin Whitepaper was written and released by Satoshi Nakamoto 16 years ago, the digital asset's impact on the world has been stunning. This asset has radically changed how the finance industry is viewed. It has given access to users who previously found it difficult to access the world's financial system. People can now sidestep the middleman and conduct transactions with their peers without going through traditional banking bureaucracies. But has it gotten to the level where it is the preferred digital asset payment system of choice?

Walk with me.

According to research by Crypto.com at the end of 2023, it was estimated that the number of users who owned Bitcoin (BTC) had increased by 33% . As per the research (and for proper context), crypto owners worldwide had grown from 432 million in January 2023 to 580 million in December 2023.

Bitcoin is like a revolutionary fruit tree, brimming with brilliant potential. This tree has created branches equally adept at changing the world, but the tree is limited by the soil it is planted in. This limiting soil is scalability—the recurring problem the Bitcoin network has faced since its inception. In the spirit of the blockchain and the ideal of innovation, there have been several solutions in recent times tackling this scalability problem.

At the forefront of this is Rootstock, the first, biggest, and longest-lasting Bitcoin sidechain. The platform is nurturing a "fertile ground" for the Bitcoin tree to flourish. This article will discuss Sidechains in the Bitcoin network and how Rootstock might be the best in the market.

The Growing Pains of a Technological Marvel

Before moving on with this section, the technological marvel here is Bitcoin. So, forward. Even though blockchain technology has become a buzzword in the tech and financial worlds, it is as real as it gets. Blockchain has impacted and changed a lot—hence the buzz. I've been writing about this technology since 2020 and it's a continuous shock every time I look back and see how far the industry has come. Blockchain technology has changed how we transact, share, and analyze data. This change has benefited business sectors like Finance, Healthcare, Retail, Entertainment, Real Estate, etc.

Fundamentally a distributed ledger system, the blockchain enables secure, transparent, immutable, and decentralized transactions. These features are the blockchain's core strengths and what gives Bitcoin its tremendous power. It is based on these principles that digital assets have been created. While Bitcoin has been a huge shift from what was previously obtainable in the finance industry, you can't help but think that there's a consistent and growing pain hindering the asset from reaching its full potential; a mainstream payment system of choice. This 'pain' is scalability.

The Scalability Challenge: Network Congestion and Exorbitant Fees

Imagine trying to drive through a crowded highway. This is how your transactions are on blockchains that suffer from network congestion. This congestion leads directly to the exorbitant fees charged by the network. Transaction fees are an essential component of any blockchain network because they help prevent spam transactions that slow down and clog the network. They also incentivize miners to validate transactions that support the network's security and keep miners profitable.

One way these fees are determined is through the demand for block space by the users. You pay more, if you want your transaction treated as a priority and confirmed faster. Transaction fees have fluctuated over time (as you'd expect from it being "highest bidder" based). We've seen fees as ($3.1 million), although this might be a case of "fat finger" on the part of the user. We've also seen fees as . All of these accumulate to a pretty penny in transaction fees. In the last year, there has been about $1.3 billion worth of transaction fees spent on the Bitcoin network. This is a bit unsettling—at least to me.

The network has also experienced clogs that have prevented it from fully being the network of choice for most users. At the time of writing, the average confirmation time for a transaction on the network is (3.5 hours). Compared to other blockchains and recently Layer-2s, this is incredibly slow.

It is this combination of high transaction fees and slow processing times—the original design only allowed seven transactions per second (TPS)—that are limitations that make Bitcoin impractical for everyday use cases. This is where Sidechains and Layer-2s have been immense.

In the next section, we'll discuss one of these solutions; Rootstock.

What is Rootstock?

Rootstock (RSK) is the pioneer, biggest, and longest-lasting open-source smart contract platform powered by and connected to the Bitcoin network through a two-way peg. Since it was introduced in 2015 by developers to help increase transaction times on the Bitcoin chain and provide smart contracts, Rootstock has been at the forefront of tackling Bitcoin's scalability challenges. The solution uses its entire technology stack (from smart contracts to infrastructure framework) to add value and functionality to the Bitcoin ecosystem by enabling smart contracts, near-instant payments, and higher scalability without compromising core features like security and decentralization on the Bitcoin network.

RSK is a separate blockchain interoperable with Bitcoin (re: primary chain) designed to create a fair and inclusive financial system. This sidechain is the only Bitcoin Layer-2 that combines the security of the network's Proof-of-Work model with the capabilities of Ethereum's smart contract. RSK's sidechain allows the movement of funds in both directions (on its blockchain that exists separately from the main chain of Bitcoin, and on the main chain).

A sidechain like Rootstock fixes the scalability woes of the Bitcoin blockchain as it allows additional tasks to be completed on a secondary chain (RSK blockchain) and then be confirmed and recognized by the primary blockchain. This decreases transaction times because the primary chain can focus on mining and validating, improving the productivity and efficiency of the network. Unlike Bitcoin where it takes around 10 minutes to verify a transaction, transactions on RSK take only. This is faster for users transferring cryptocurrency on the network, significantly reducing waiting times and costs.

Some platforms that have integrated Rootstock's technologies include Symbiosis, SushiSwap, LI.FI, Jumper Exchange, Asami, Oku, etc. By merging its smart contract capabilities with these platforms, Rootstock enables the development of innovative DeFi applications like lending and borrowing platforms. Some of these platforms use the Rootstock Infrastructure Framework (RIF) token to facilitate faster and cheaper cross-border payments.

Rootstock is a product of RootstockLabs, a company that builds innovative solutions within the blockchain industry, empowering developers with funding, technology, and marketing support. RootstockLabs is dedicated to expanding the frontiers of decentralization and is on a mission to make Bitcoin work for everyone.

How Rootstock Works

Rootstock runs alongside the Bitcoin blockchain through a federated peg system—transferring assets between blockchains without needing a traditional exchange. Bitcoin (BTC) can be locked on the primary chain and represented as a smart contract-enabled bitcoin, RSK Bitcoin (RBTC) on the secondary chain. The RBTC is the native token of the Rootstock ecosystem and is pegged 1:1 to BTC. This token can be used as gas to pay for smart contract executions, just like how ETH is used as gas for Ethereum.

RBTC can be obtained by converting to and from BTC through the bridge between Bitcoin and Rootstock protocols. Less technical users can get the token from cryptocurrency exchanges.

The Rootstock system is managed by a group of entities known as the federation. Each member of this group operates a node that participates in the approval of transactions to either lock or unlock BTC. They are chosen based on security, trustworthiness, and stake in the ecosystem. No single entity has full control of the funds as it is held in a multi-signature wallet that requires a majority of the federation members to sign for funds to be released.

Benefits of Rootstock for Bitcoin Users and Developers

• Scalability: Rootstock boasts off-chain payment channels similar to the Lightning Network, which significantly increases throughput, improving transaction speed and reducing costs. At the start, Rootstock blocks every 20 seconds and 300 TPS but can now scale up to 1000 TPS without sacrificing decentralization.

• Smart Contract Functionality: RSK has a smart contract functionality that is Ethereum-like, enabling a vibrant ecosystem of decentralized applications (dApps) built on top of Bitcoin.

  
  

• Seamless integration with Bitcoin, allows users to transfer assets between Bitcoin (BTC) and Rootstock (RBTC). This preserves Bitcoin's liquidity and user base while allowing users to leverage both worlds.
