A Brief History of Solana Decentralized Trading Infrastructure from Serum to OpenBook

Serum:

Serum launched on the Solana blockchain as one of the first decentralized exchanges for the new platform. It was a Central Limit Order Book that provided a familiar trading environment for regular tradFi investors. This allowed the DeFi space to flourish on Solana as it helped bring reputable investors and institutional traders into the Even though the source code for Serum was open to all, the Serum Foundation with ties to FTX controlled the program update key. To summarize this story, anyone with the keys can “rug” the DeFi ecosystem on Solana. Or another equally worse scenario is an exploit in the codebase.

OpenBook:

Immediately after the FTX collapse, the risk of being hacked or someone stealing the update keys to the Serum DEX used across the Solana DeFi brought about a quick response from the community to create a fork of the Serum code to mitigate the centralization and risks that developers were faced with in addition to the fact that there won’t be code updates anymore since the FTX team was dissolved. Some of the characteristics of OpenBook are:

• On-chain order book: All orders are stored directly on the Solana blockchain, ensuring transparency and immutability.

• Focus on decentralization: OpenBook is governed by its community and has no central authority controlling the platform.

• Security focus: OpenBook prioritizes security and has undergone multiple audits to address vulnerabilities.

• Lower liquidity: Initially struggled to compete with Serum's established liquidity pools.

Growing user base: Attracting users who value transparency and decentralization, and actively building its own liquidity pools

Introducing Phoenix

Phoenix is a decentralized limit order book on Solana supporting markets for spot assets.

Phoenix provides a composable liquidity hub that is positive for the Solana DeFi ecosystem. Developers can add or draw liquidity from the liquidity source onchain. Formerly used models like AMMs mostly rely on unsustainable liquidity incentives to “sustain” itself for as long as possible or liquidity providers have to make peace with losing money steadily. Because of Phoenix and Solana’s technical capabilities, professional market makers can provide a more robust liquidity while being profitable and actually sustainable.

But how exactly does Phoenix work?

Phoenix Trade DEX: Rising from the Ashes of Old Solana DeFi

New projects emerge with the promise of revolutionizing the way we interact with our digital assets. One such rising star is Phoenix Trade DEX, a spot trading platform built on the Solana blockchain.

Launched in September 2023, Phoenix has already gained traction amongst Solana users because of its unique approach to order books, instant withdrawals, and focus on DeFi accessibility.

Breaking the Mold: On-Chain Order Books for Transparency and Speed

Unlike most DEXes on Solana, Phoenix utilizes an on-chain order book. This means that all orders are stored directly on the blockchain, ensuring transparency and immutability. This contrasts with off-chain order books, which are vulnerable to manipulation and centralization. With Phoenix, users can be confident that their orders are visible and recorded on the public ledger, providing a sense of security and trust. This “trust” is verifiable.

The on-chain order book also translates to faster trade execution. Orders are matched and settled directly on the blockchain, eliminating the need for intermediaries and reducing transaction latency. Since Solana is fast enough to accommodate this vigorous demand, Phoenix flourishes as intended. This translates to a smoother and more efficient trading experience for users.

Instant Withdrawals: Unlocking Liquidity with Freedom

One of Phoenix's most defining features is its instant withdrawal functionality. Traditionally, DEXes hold user funds in a central pool, leading to delays when users want to withdraw their assets. Phoenix eliminates this bottleneck by allowing users to withdraw their funds directly from their wallets after each trade. This significantly improves liquidity and capital efficiency, giving users greater control over their assets.

Democratizing DeFi: User-Friendly Interface and Community Focus

Phoenix understands that the DeFi space can be intimidating for newcomers. The platform prioritizes a user-friendly interface and extensive documentation to guide users through the trading process. Additionally, Phoenix actively engages with its community through social media channels and Discord, fostering a collaborative environment where users can learn and share knowledge. (P.S., I will be doing a Part 2 of this article that explains and shows how to use the dapp practically).

Beyond Spot Trading: Phoenix's Future in DeFi

While currently focused on spot trading, Phoenix has ambitious plans for the future. The team is actively developing features like margin trading, lending, and yield farming, aiming to create a comprehensive DeFi ecosystem on Solana. Additionally, Phoenix is exploring integrations with other DeFi protocols to expand its functionality and offer users a more holistic experience.

Challenges and Opportunities: Navigating the DeFi Landscape

Despite its promising features, Phoenix faces challenges in the competitive DeFi landscape. Establishing user trust and attracting liquidity are crucial for any DEX, and Phoenix must continue to build its reputation and brand awareness. Additionally, staying ahead of the curve in terms of technological innovation is critical for long-term success.

However, the potential for Phoenix is undeniable. Its focus on on-chain transparency, instant withdrawals, and user-friendliness addresses some of the key pain points in the current DeFi landscape. If Phoenix can continue to execute its roadmap and build a strong community, it has the potential to become a major player in the DeFi space on Solana.

Let’s look at some technical features and primitives packaged in the Phoenix DeFi infrastructure.

Technical Features

• Phoenix has instant settlement. Unlike existing order books on Solana, Phoenix doesn't require an asynchronous crank to settle trades.This is what it means when devs say Phoenix is “crankless”. Just think of it as “instant”. It’s not that hard. (Although it can also be used metaphorically as a new platform that is rising without hindrances caused by the old system of DeFi operation. It can also mean that all activities like order matching and withdrawals require no manual involvement as all instructions are automated via smart contracts).

• Phoenix is maximally composable. Phoenix's sensible interfaces and small number of accounts required mean that traders can fit more instructions into a single transaction.

• Phoenix cleanly exposes data. All market events (limit order placed, limit order canceled, fills, etc.) are written on-chain, so it's easy for traders to query the full live and historical state of all Phoenix markets

Phoenix Trade DEX is a breath of fresh air in the world of DeFi. Its innovative approach to order books, focus on instant withdrawals, and commitment to user-friendliness position it for success in the competitive Solana ecosystem. While challenges remain, Phoenix's dedication to transparency, efficiency, and community engagement suggests a promising future for this rising DeFi star.

Phoenix Trade DEX: A Technical Deep Dive

Beneath the user-friendly interface of Phoenix Trade DEX lies an innovative technical architecture designed for speed, security, and decentralization. Let's delve into the key elements that make Phoenix tick:

1. On-Chain Order Book: Transparency and Immutability

Phoenix's core innovation lies in its on-chain order book. Unlike most DEXes on Solana, which rely on off-chain order books hosted by centralized servers, Phoenix stores all orders directly on the Solana blockchain. This offers several advantages:

• Transparency: All orders are publicly visible and verifiable, preventing manipulation and ensuring fair market conditions.

• Immutability: Once recorded, orders cannot be altered or deleted, guaranteeing the integrity of the order book and preventing fraudulent activity.

• Security: Orders are protected by the inherent security of the Solana blockchain, minimizing the risk of hacking or theft.

However, on-chain order books also present challenges. Storing large volumes of data on the blockchain can be expensive and consume block space. Phoenix addresses this by employing a combination of techniques:

• Order compression: Orders are compressed using efficient data structures, minimizing storage requirements.

Batching: Orders are aggregated and submitted to the blockchain in batches, reducing transaction fees and network congestion. This is a bit similar to what Jito does with the Jito Bundling mechanism for submitting orders to the leading validators for block creation.

2. High-Performance Matching Engine - Unparalleled Speed and Efficiency

Phoenix utilizes a custom-designed matching engine for order execution. The engine efficiently matches buy and sell orders based on price and time priority, ensuring fast and fair trade execution. Key features of the matching engine include:

• Deterministic matching: Order execution is deterministic, meaning the same outcome is guaranteed regardless of the execution node, further enhancing fairness and security.

• Parallel processing: Orders are processed simultaneously on multiple nodes, maximizing throughput and minimizing latency.

• Mempool optimization: The engine prioritizes orders in the category of pending transactions) based on their impact on the market, ensuring efficient utilization of block space.

3. Instant Withdrawals: A Paradigm Shift in DeFi

Phoenix's instant withdrawals feature is a game changer in the DEX landscape. Users can withdraw their assets directly from their wallets after each trade, without waiting for settlement periods or centralized pool distributions. This innovative functionality is enabled by:

• Atomic swaps: Phoenix utilizes atomic swaps, a cryptographic technique that ensures both parties receive their desired assets simultaneously, eliminating the risk of counterparty default and enabling instant withdrawals.

• Liquidity pools: Phoenix maintains a network of decentralized liquidity pools that provide sufficient liquidity for withdrawals and trading.

4. Secure Infrastructure and Smart Contract Design

Phoenix prioritizes security at all levels. The platform utilizes secure smart contracts audited by reputable firms to minimize vulnerabilities and protect user funds. Additionally, Phoenix employs a multi-layered security architecture, including:

• Distributed infrastructure: The platform operates on a decentralized network of nodes, preventing single points of failure and enhancing resilience against attacks.

• Secure communication protocols: All communication between nodes and users is encrypted using TLS, ensuring data privacy and integrity.
