Introducing Bluefin v2 – Decentralized Trading Without Wallets

Published

introducing-bluefin-v2-–-decentralized-trading-without-wallets

 

 

LONDON, Sept. 12, 2023 /PRNewswire/ — We are excited to announce Bluefin v2 – the next step of our decentralized, orderbook-based exchange. Bluefin v1 supports the trading of perpetual swaps and is currently powered by Arbitrum, a layer 2 blockchain leveraging the security of Ethereum. To this day, v1 has processed over $1 billion in trading volume. While we will continue to operate and maintain Bluefin v1, with v2 we aim to build a decentralized platform that can match the features and trading experience of centralized exchanges, for both professional and first-time traders. This includes supporting new features such as spot trading as well as overcoming the performance limitations and high gas fees on existing Layer 2s. Today, we look forward to sharing this next iteration of the exchange.

Key Takeaways

  • Timeline: Bluefin v2 will be released in a beta state in September followed by several features that include instant trade confirmations, sub-second finality, fully-decentralized spot markets, cross-margin, and trading without wallets. These will be rolled out over the next six months.
  • Performance: ~30ms optimistic trade confirmations, ~550ms finality, 5,400+ peak TPS
  • Eliminating Wallets: We’re working to emulate the Web2 trading experience while retaining the decentralization benefits of an on-chain trading protocol
  • Cost of Execution: The spread on Bluefin v1 is currently <0.001% and with reduced latencies and gas fees below $0.005 on v2, users will benefit from even lower trade execution costs.

Bluefin v2

We are now excited to announce Bluefin v2. Over the course of this year, we’ve rewritten our codebase and built on a new underlying technology. Bluefin v2 is built on Sui, which enables horizontally scalable performance and a wallet-less trading experience that competes with the user experience of a centralized exchange. With Bluefin v2, we introduce

  1. Optimistic trades streamed sub-second and eliminating the need for wallets.
  2. Spot trading using Sui’s on-chain orderbook, further enhancing our decentralization, transparency, and security.
  3. A new margining engine with cross-margining capabilities.
  4. An underlying layer 1 that has seen a peak throughput over 5400 TPS on mainnet and a peak throughput ranging from 10,871 TPS to 297,000 TPS while benchmarking in a series of tests

Performance

Our goal is to ensure that users experience sub-second trades, finalized on-chain, and reflected instantly on their UI. These are two key performance components of Bluefin v2: optimistic trade confirmations and on-chain finality.

With Sui’s parallel execution, the availability of the network is not constrained by other applications and users. As a result, the success rate of transactions submitted on-chain is extremely high. Building on this guarantee, we’ve redesigned the off-chain orderbook layer to start sending optimistic confirmations of trades in ~30ms back to users and ensuring eventual consistency with the on-chain smart contracts in ~480ms on average based on benchmarking in a production environment.

A hyper-performant trading experience with 30ms optimistic confirmations and sub-second on-chain finality

Eliminating Wallets While Remaining Non-Custodial

We’re working on eliminating the need for users to bring their own wallets by making on-chain interactions invisible to users. Abstracting away private key management and the need for wallets altogether, while remaining non-custodial, is a key milestone for decentralized finance.  There are three phases here: i) natively-supported social login using zkLogin, ii) easy fiat on-ramp and transfers from other exchanges and blockchains, and, iii) eliminating wallets altogether.

Bluefin to support a wallet-less trading experience while remaining non-custodial

We will be releasing v2 features on a rolling basis over the course of the next 6 months, however, an early version of the protocol will be available later this month. The current version of the exchange is live: trade.bluefin.io

JAKARTA, Indonesia, Oct. 18, 2024 /PRNewswire/ — Nium, the leading global infrastructure for real-time cross-border payments, is thrilled to announce a partnership with Bank Rakyat Indonesia (BRI) to provide Indonesian customers with real-time international money transfer capabilities. This collaboration aims to enhance the cross-border offerings for BRI’s individual and corporate customers, delivering more accessible and cost-effective financial services across Indonesia.

This partnership empowers more than 150 million BRI account holders, including those in remote regions of Indonesia, to access modern, real-time cross-border payment services. The offering includes a variety of real-time payment mechanisms, supporting bank account destinations, a global electronic card network, and digital wallets. These innovations are closely aligned with BRI’s ongoing mission to provide affordable and customer-focused financial products, particularly for traditionally underserved communities.

BRI’s Corporate Secretary, Agustya Hendy Bernadi, emphasized BRI’s dedication to constantly improving customer convenience through innovations in its global network and cross-border transaction services. “This collaboration reflects BRI’s continuous efforts to enhance productivity and efficiency by expanding its digital payment channel network to meet the growing demand for global transactions,” he said. Agustya added that the partnership with Nium aligns perfectly with BRI’s vision to be Southeast Asia’s most valuable banking group and a champion of financial inclusion by 2025. “With Nium’s global transaction network, BRI strengthens the digitalization of its business processes and enhances retail banking capabilities in line with our 2025 strategic vision.”

Anupam Pahuja, General Manager and Executive Vice President for Asia Pacific, Middle East, and Africa at Nium, shared his excitement about the partnership, highlighting BRI’s extensive presence across Indonesia’s 17,000 islands. “By integrating Nium’s advanced technology into BRI’s platform, we are dedicated to providing BRI’s customers, no matter where they are, with access to exceptional financial services. This partnership will remove the risks associated with cash handling and provide faster, more cost-effective transactions—whether individuals are sending money to family members abroad or businesses are making international payments.”

Cross-border payments are projected to grow significantly in Indonesia, with a forecasted year-on-year increase of 15% through 2025, driven largely by the digital transformation in financial services (Statista, 2024).

This partnership between BRI and Nium is expected to transform the way Indonesians engage with global financial services, meeting the rising demand for modern payment infrastructure and enhancing the overall experience for BRI’s customers in their international transactions.

Grexie Signchain Launches on November 1st, 2024: Enabling Smart Contract Developers to Bring Off-Chain Data On-Chain with Seamless Gas-Paid Signing

Published

grexie-signchain-launches-on-november-1st,-2024:-enabling-smart-contract-developers-to-bring-off-chain-data-on-chain-with-seamless-gas-paid-signing

Grexie Signchain enables developers to sign off-chain data into smart contracts, with self-hosted or secure vault signer wallet management.

MANCHESTER, England, Oct. 17, 2024 /PRNewswire/ — Grexie Limited proudly announces the launch of its innovative smart contract solution, Signchain, on November 1st, 2024. Designed specifically for developers, Signchain introduces a powerful way to bring off-chain data on-chain through user-paid gas fees and secure signing of data into smart contract methods using its extendable smart contract, Signable.

In the growing landscape of blockchain technology, securely managing off-chain data and integrating it into on-chain smart contracts has posed significant challenges for developers. Signchain eliminates these hurdles by offering a robust, gas-efficient system for signing and authenticating data in real-time.

Key Features of Signchain:

1. Seamless Off-Chain to On-Chain Data Integration
Signchain enables developers to securely bring off-chain data on-chain by signing it directly into smart contract methods through user-paid gas fees. This integration ensures that data authenticity is preserved, and its entry into the blockchain remains tamper-proof, streamlining processes for industries relying on real-world data verification. Signchain also supports integration with Google Sheets, AWS, and Firebase, making it easy to pull data from popular off-chain data sources.

2. Extendable Smart Contract – Signable
The core of Signchain’s technology is its extendable smart contract, Signable, which allows developers to customize and build upon existing smart contracts. With Signable, developers can easily implement contract signatures for any data type, offering flexibility across industries from finance to logistics and beyond.

3. Signer Wallet Management
Signchain offers comprehensive signer wallet management as part of its service, empowering developers to manage and authenticate signers effectively. Wallets can either be self-hosted using Signchain’s Docker container for those who prefer their own infrastructure, or they can leverage Signchain’s network of secure vaults for maximum security.

4. Self-Hosted or Managed Service
For developers who want full control of their infrastructure, Signchain provides a self-hosted option via Docker containers, allowing them to deploy the platform on their own servers. Alternatively, developers can opt to use Signchain’s secure vault network, offering a hassle-free solution with enterprise-grade security and wallet management.

5. User-Paid Gas Fees
By integrating a user-paid gas fee model, Signchain allows users to cover the costs of signing and authenticating their data, ensuring the signing process is efficient and doesn’t overburden developers with additional expenses. This makes Signchain an ideal solution for dApps and platforms handling high transaction volumes.

6. Google Sheets, AWS, Firebase Integration with Serverless Model
Signchain supports integration with Google Sheets, AWS, and Firebase in a serverless model, powered by a hosted Sign In With Ethereum (SIWE) implementation provided by Signchain’s API. Developers can simply connect their Google Sheets and configure the contract parameters associated with each column. Signchain will automatically look up the user’s wallet address in the spreadsheet, sign the transaction data, and execute it in the blockchain along with any user-supplied parameters. This creates an easy, efficient way to manage data inputs from off-chain sources without heavy infrastructure setup.

Revolutionizing Smart Contract Workflows

With Signchain, developers now have the tools to handle the complexities of integrating off-chain data into smart contracts. The extendable nature of Signable offers flexibility, allowing developers to cater to various use cases, whether it’s automating financial transactions, supply chain data, or verifying legal agreements.

Tim Behrsin, CEO of Grexie Limited, said, “Signchain is more than just a signing solution—it’s a platform that empowers developers to securely integrate off-chain data into their smart contracts with minimal effort. The flexibility of Signable and our focus on signer wallet management offers developers control and security at every stage of the process.”

Why Signchain Matters

Signchain addresses critical challenges faced by developers, particularly those dealing with off-chain data. By signing data into smart contracts and enabling user-paid gas fees, the platform significantly reduces friction in managing secure, scalable smart contracts. Whether developers need to manage high volumes of data transactions or create bespoke smart contracts, Signchain offers a scalable and secure solution.

In industries like DeFi, real estate, and supply chain management, data integrity and security are paramount. Signchain’s secure vault network and customizable signing workflows allow businesses to handle sensitive information with confidence.

Launch Event and Future Developments

The official launch of Signchain will take place on November 1st, 2024, alongside a virtual event. The event will showcase live demonstrations of Signable, with detailed walkthroughs of the Docker-based self-hosted solution and signer wallet management features. Attendees will also get an exclusive preview of future enhancements, including multi-signature workflows and advanced blockchain network integrations.
