Plasma Ethereum Scalability Framework to Handle High Throughput

Ethereum has emerged as one of the most popular and widely used blockchain platforms over the past few years. However, as Ethereum has grown, it has faced scalability challenges that have hampered its ability to process high transaction volumes and throughput. This has led to increased transaction fees, network congestion, and slow confirmation times.

What is Plasma?

Plasma is a layer-2 scaling framework that was proposed by Vitalik Buterin and Joseph Poon in 2017 as a solution to help Ethereum scale. The key idea behind Plasma is to move computation and data storage off the main Ethereum blockchain onto side chains called "Plasma chains".

These Plasma chains can process large volumes of transactions while only periodically updating the main Ethereum blockchain. This helps relieve congestion on the main chain and enables much higher throughput. Plasma allows for decentralized application processing without the need for every single transaction to be recorded on the primary blockchain.

How Does Plasma Work?

Plasma operates as a tree of chains that branch off the main Ethereum blockchain. Each Plasma chain can have its own set of rules and transactions but ultimately anchors back to the main Ethereum chain.

When a transaction occurs on a Plasma chain, a cryptographic proof is generated and published to the main blockchain. However, the bulk of the transaction data is maintained on the Plasma chains. Periodically, the Plasma chain roots are committed to the main chain.

This provides security assurances that the Plasma chains are valid while keeping the data localized. If there is any invalid activity, participants can exit the Plasma chain to withdraw their funds safely on the main chain.

Potential Benefits of Plasma

Plasma brings several important benefits:

  • Scalability - By moving transactions off-chain, Plasma enables vastly higher throughput, up to potentially millions of transactions per second compared to 15 TPS for Ethereum currently. This solves critical needs around scaling.
  • Lower fees - With greater throughput on side chains, transaction fees can be lowered significantly versus the main blockchain.
  • Faster transactions - Transactions on Plasma side chains can have faster confirmation times and higher responsiveness.
  • Interoperability - Plasma chains can connect with each other and even non-Plasma chains, enabling cross-chain transactions.
  • Security - Plasma chains benefit from the underlying security of the Ethereum mainnet. And users can exit out to the main chain in case of Plasma chain issues.
Implementation Challenges

While Plasma brings major advantages, it also faces some challenges with real-world implementation:

  • Complex exit procedures - Withdrawing funds from Plasma chains back to mainnet can have complex exit games that may create issues and delays for users.
  • User adoption - Gaining critical user adoption on new Plasma chains can be difficult to achieve initially when liquidity is low.
  • Computation requirements - Validators of Plasma chains need sufficient capabilities to handle computation and data requirements.
  • Sybil attacks - Plasma chains face risks of Sybil attacks and other security issues without sufficient decentralization and security measures.
  • Fragility - Buggy or poorly implemented Plasma chains carry risks of fund loss and irreversibility that may prompt risk aversion.
Current Plasma Projects

There are multiple Plasma implementations and chains being built and tested:

  • Ethereum Plasma - OmiseGO is building a full-featured Plasma implementation designed for exchange activity.
  • Plasma XT - Optimized Plasma chain design focused on ease of use and UX.
  • Plasma Debit - Unidirectional payment channel network for recurring payments.
  • Plasma Cash - Improves security using unique coin identifiers but faces scaling limitations.
  • Polygon - Leading Plasma-based scaling solution for Ethereum with PoS chain and other features.
  • OMG Network - Public network by OmiseGO for transaction processing and eWallet services.
The Road Ahead

Plasma represents one of the most promising paths forward for scaling Ethereum. Considerable progress has already been made with early implementations of Plasma demonstrating potential.

However, work remains to build robust, decentralized multi-chain ecosystems and gain user adoption. Usability, security, and interoperability are critical areas of focus. The coming 1-2 years will prove pivotal in moving Plasma from theoretical framework to practical large-scale usage.

Plasma, alongside other layer-2 technologies like state channels and sidechains, is likely to play a major role in fulfilling the scalability needs of Ethereum and enabling it to reach its full potential.

Plasma has the capacity to significantly enhance the usability and experience of decentralized applications (DApps) on Ethereum by providing much greater scalability. Some potential transformative impacts include:

  • Smoother UX - With faster confirmation times and lower fees on Plasma side chains, DApp transactions and usage can be seamless for users. No more clogged networks.
  • Higher throughput - DApps like exchanges, games, prediction markets can support higher concurrent user volumes and activity without congestion.
  • Data availability - Plasma allows DApps to leverage greater data availability and compute without needing main chain storage.
  • Novel DApp designs - New DApp opportunities like streaming payments, IoT connectivity, and real-time gaming interactions become possible.
  • Lower costs - Users benefit from radically lower transaction fees to use their favorite DApps. Removes pain point.
  • Wider onboarding - Plasma's scalability unlocks the door for onboarding mainstream users to Ethereum DApps by resolving key usability issues.

By dynamically sharding computation and throughput to Plasma side chains, Ethereum's core congestion issues impacting DApp usability could be resolved by orders of magnitude. This promises to accelerate adoption and usher in exciting new DApp opportunities.

For businesses, Plasma chains open up new ways to leverage Ethereum blockchain technology because of their scalability, lower costs, and faster transaction times. Some examples of potential business usage include:

  • Payment channels - Plasma enables high volume, low cost payment channels for recurring billing and subscriptions.
  • Supply chain tracking - Real time supply chain data can be recorded on Plasma with blockchain provenance.
  • Identity management - Digital IDs verified on Plasma chains could enable access to accounts, licenses, certifications.
  • Tokenization platforms - Fungible and non-fungible tokens for gaming, licensing, finance tokenized on Plasma.
  • IoT data ingestion - Data streams from IoT devices could be immutably recorded on Plasma chains.
  • Automated marketplaces - Plasma-based decentralized marketplaces remove intermediaries and overhead.

By leveraging Plasma chains, businesses can target specific use cases that benefit from high transaction throughput at lower costs compared to mainnet. While leveraging Ethereum's security and retaining flexibility to move assets back to mainnet when needed.

As innovations continue in Plasma implementations, it will be exciting to see businesses embrace and mold this technology to suit a wide range of applications.


Plasma represents a leading light in resolving the scalability needs of Ethereum. By branching computation and storage into multi-chain ecosystems, Plasma can enable the scale and performance necessary for mainstream blockchain adoption.

Much work remains across areas of security, usability, and adoption, but the pace of development is promising. In the coming years, Plasma is poised to make a major impact in unlocking Ethereum to reach its full decentralized potential across payments, finance, identity, supply chains, and a vast range of other applications.
