FastPeercoin: A Fast and Scalable
Peer-to-Peer Currency
Abstract
FastPeercoin is a decentralized cryptocurrency engineered to facilitate rapid, low-cost
transactions, making it an ideal medium for everyday use. With a target block time of 1
minute and a hybrid proof-of-work (PoW) and proof-of-stake (PoS) consensus mechanism,
FastPeercoin combines high transaction throughput with robust security and
decentralization. Unlike many existing cryptocurrencies that prioritize wealth storage,
FastPeercoin aims to fulfill the original vision of a true P2P electronic cash system, enabling
seamless payments for merchants and consumers alike.
1. Introduction
Since Bitcoin introduced the world to decentralized digital currencies in 2008,
cryptocurrencies have gained widespread adoption. However, limitations such as slow
transaction confirmation times and high fees during network congestion have hindered their
practicality for everyday use. Bitcoin’s 10-minute block time, for instance, delays transaction
finality, making it less suitable for quick purchases like buying a coffee or paying for services
online.
FastPeercoin addresses these challenges by offering faster transaction confirmations and
lower costs, positioning it as a viable currency for daily transactions. By leveraging a hybrid
PoW/PoS system and a 1-minute block time, FastPeercoin ensures efficiency, security, and
accessibility, aligning with the ethos of a true P2P coin.
2. The Problem
Many cryptocurrencies, including Bitcoin, face practical limitations as transactional
currencies:
● Slow Transaction Times: Bitcoin’s 10-minute block time results in confirmation
delays, often requiring users to wait for multiple blocks (e.g., 6 confirmations = 1
hour) for secure settlement.
● High Fees: During periods of high demand, transaction fees spike, discouraging
small-value transactions.
● Store-of-Value Focus: The design of many cryptocurrencies incentivizes holding
rather than spending, reducing their utility as circulating currencies.
These factors make existing solutions suboptimal for real-world commerce, where speed,
affordability, and ease of use are paramount. FastPeercoin seeks to bridge this gap by
prioritizing transactional efficiency while maintaining the decentralized principles of P2P
systems.
3. The Solution: FastPeercoin
FastPeercoin is designed to overcome the limitations of traditional cryptocurrencies by
optimizing for speed, scalability, and usability. Its key features include:
● 1-Minute Block Time: Ten times faster than Bitcoin, enabling rapid transaction
confirmations.
● Hybrid Consensus: Combines PoW for fair initial distribution with PoS for
energy-efficient security and block generation.
● Low Fees: Fixed, minimal transaction costs to encourage widespread use.
● P2P Focus: Emphasizes decentralization and usability for everyday payments rather
than investment holding.
By focusing on these attributes, FastPeercoin aims to serve as a practical currency for
online shopping, in-store purchases, remittances, and more.
4. Technical Design
4.1 Consensus Mechanism
FastPeercoin employs a hybrid PoW/PoS system inspired by Peercoin, the first
cryptocurrency to introduce proof-of-stake. This dual approach balances fairness, security,
and efficiency:
● Proof-of-Work (PoW): Used during the initial coin distribution phase to ensure a
decentralized launch without pre-mining. Miners solve computational puzzles to
generate blocks and earn rewards.
● Proof-of-Stake (PoS): After the initial phase, PoS dominates block generation.
Stakeholders "stake" their coins to validate transactions and create blocks, earning
rewards proportional to their holdings and coin age (time held). This reduces energy
consumption compared to pure PoW systems.
The protocol targets an average block time of 1 minute by calibrating the difficulty of PoW
and the staking requirements of PoS.
4.2 Block Time
With a 1-minute block time, FastPeercoin processes blocks ten times more frequently than
Bitcoin. This allows for:
● Faster Confirmations: A single confirmation takes 1 minute, and merchants can
accept payments with 2-3 confirmations (2-3 minutes) for most use cases.
● Higher Throughput: Assuming a block size similar to Bitcoin’s 1MB, FastPeercoin
can handle approximately 30-70 transactions per second (tps), a significant
improvement over Bitcoin’s 3-7 tps.
4.3 Transaction Fees
To ensure affordability, FastPeercoin implements a fixed fee of 0.01 FPC per transaction.
Unlike traditional fee markets, these fees are burned (destroyed) rather than paid to miners
or stakers. This mechanism:
● Prevents network spam by imposing a minimal cost.
● Controls inflation by reducing the circulating supply over time.
4.4 Coin Age
In the PoS system, coin age—the product of the number of coins and the time they’ve been
held—determines staking eligibility. This encourages active participation and prevents
excessive centralization by rewarding long-term holders who contribute to network security.
5. Security and Scalability
Faster block times introduce challenges such as increased orphan rates (blocks not
included in the main chain) and network propagation delays. FastPeercoin addresses these
through:
● Advanced Propagation Protocols: Techniques like compact block transmission
reduce the data size of blocks, ensuring rapid dissemination across the network.
● Checkpointing: Periodic finalized blocks prevent deep reorganizations and enhance
security against attacks.
● Dynamic Adjustments: The protocol fine-tunes PoW and PoS difficulties to
maintain a consistent 1-minute block time, even under varying network conditions.
For scalability, FastPeercoin’s base layer supports moderate transaction volumes (30-70
tps). Future enhancements, such as larger block sizes or layer-2 solutions (e.g., payment
channels), can further increase capacity without compromising decentralization.
6. Economic Model
Unlike Bitcoin’s fixed supply, FastPeercoin adopts a controlled inflation model to encourage
circulation:
● Initial Distribution: Coins are distributed via PoW mining during the launch phase,
ensuring fairness and decentralization.
● PoS Minting: Stakers receive a 1% annual reward on their staked coins, introducing
a small inflation rate. This incentivizes network security and provides a steady coin
supply for transactional use.
● Fee Burning: The destruction of transaction fees offsets inflation, stabilizing the
money supply over time.
This balance discourages hoarding and promotes spending, aligning with FastPeercoin’s
goal as a currency.
7. Use Cases
FastPeercoin’s design makes it suitable for a variety of real-world applications:
● Online Payments: Fast confirmations and low fees enable seamless e-commerce
transactions.
● In-Store Purchases: Merchants can integrate FastPeercoin into point-of-sale
systems for quick, affordable payments.
● Remittances: Low-cost cross-border transfers benefit users in regions with high
banking fees.
● Microtransactions: The efficiency of FastPeercoin supports small payments, such
as tipping or content monetization.
8. Comparison with Existing Solutions

sustainability and efficiency.
9. Implementation Plan
FastPeercoin will be developed as an open-source project with the following roadmap:
● Phase 1: Design and Testing - Develop the protocol and launch a testnet to refine
parameters.
● Phase 2: Mainnet Launch - Initiate PoW mining for a fair, decentralized distribution.
● Phase 3: Adoption - Partner with merchants and payment processors to integrate

10. Conclusion
FastPeercoin reimagines cryptocurrency as a practical, everyday currency. By combining a
1-minute block time with a hybrid PoW/PoS system, it delivers fast, affordable transactions
while preserving the decentralization and security of a true P2P coin. With its focus on
usability and efficiency, FastPeercoin has the potential to redefine how digital currencies
serve the global economy.
