Introducing Bluefin v2 – Decentralized Trading Without Wallets

Published

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

President Emmerson Mnangagwa met this week with Zambia’s former Vice President and Special Envoy Enoch Kavindele to discuss SADC’s candidate for the AfDB

President Mnangagwa, who is SADC Chairperson, reaffirmed his own country’s and SADC’s enthusiastic support for Zambian candidate Sam Maimbo

LUSAKA, Zambia, Dec. 20, 2024 /PRNewswire/ — Special Envoy Kavindele released the following statement following the meeting:

“I am elated to witness the growing success and momentum of Sam Maimbo’s candidacy to become the next President of the African Development Bank. I am filled with gratitude to our friends across both SADC and COMESA for their continued support and good wishes.

Sam has garnered such wide consensus due to his being uniquely qualified to deliver the transformative change and empowerment our continent needs. Sam’s 30 years in development work is defined by driving outcomes, improving processes, and investing in people. The AfDB needs a hands-on leader who is laser focused on delivering results and who is unafraid of making tough decisions in order to best serve our continent. Sam is that leader. Sam has the track record and experience to drastically enhance the pace, scale, and impact of the Bank’s work in service of the people and governments of Africa.

Our region has a proud history of supporting fellow Southern Africans. For example, we all recall Lusaka’s role in hosting the African National Congress’ headquarters during the dark days of Apartheid oppression.

It therefore gives me no pleasure to observe my South African brothers, who have themselves leant on Zambia’s steadfast friendship over many decades, fail to rally behind both SADC and COMESA’s chosen candidate for the AfDB. Africa’s urgent economic development challenges demand transformational leadership at the AfDB, it is all of our responsibility to put forward the best candidate for the job. This is not the time or place for a government to act with narrow self-interest, we all must act in the continent’s and AfDB’s best interest.

I thank Sam Maimbo for his lifelong service to our entire continent, and I am eager to witness his enormous impact as President of the AfDB.”

Key Tips to Protect Businesses This Holiday Season:

  1. Strengthen endpoints: Ensure devices are updated with antivirus and endpoint protection software; consider Endpoint Detection and Response (EDR) and application whitelisting.
  2. Prepare for phishing spikes: Train staff to identify suspicious emails, enforce robust email filters, and establish protocols for reporting unusual activity.
  3. Secure remote access: Mandate VPN usage, monitor unusual logins, and deactivate inactive accounts temporarily.
  4. Segment and shield networks: Isolate sensitive areas, deploy DNS security and advanced firewalls, and maintain full visibility over network traffic.
  5. Apply timely patches: Regularly update all systems and test patches in a controlled environment to minimize disruptions.
  6. Mitigate supply chain risks: Assess vendors thoroughly and limit their access to essential systems.
  7. Have a response plan ready: Tailor incident protocols for the holidays, create an on-call rotation for the IT team, and enable rapid action against suspicious activity.

Cybercriminals thrive on holiday distractions, but with proactive measures like phishing training, secure endpoints, and network segmentation, businesses can stay ahead of potential threats,” said Alex Panait, System Administrator at Heimdal Security.

According to Tickmill survey, 3 in 10 Britons in economic difficulty: Purchasing power down 41% since 2004

Published

on

according-to-tickmill-survey,-3-in-10-britons-in-economic-difficulty:-purchasing-power-down-41%-since-2004

The people who have the most problems are women (30%) and are between 35 and 49 years old (39%)

ROME, Dec. 20, 2024 /PRNewswire/ — The purchasing power in the UK has dropped by 41% over the last 20 years. Today, £100,000 left in a bank account since 2004 without being invested would now be worth £59,021.

This figure is one of the findings from a study conducted by Tickmill, an international online trading broker that compared the economic situation in the UK and the European Union through the infographic “Purchasing Power and Cost of Living: UK vs EU”.

The analysis reveals a slight decline of 0.4% in the UK’s purchasing power, which currently stands at £41,573. In contrast, the European Union has seen a modest rise of 0.1%, reaching £40,874.

Why is purchasing power declining in the UK? One key factor is the cost of living. If the UK were still part of the European Union, it would rank as the fifth most expensive country, behind Ireland, Luxembourg, Denmark, and the Netherlands.

Unsurprisingly, 3 in 10 Britons are struggling with the cost of living. Women (3 in 10, compared to 25% of men), those aged between 35 and 49 (4 in 10), households earning less than £15,000 (6 in 10), and single parents (1 in 2) are among the most affected groups.

Among UK nations, Northern Ireland is the hardest hit, with 34% of its population facing financial difficulties, followed by Wales (31%), England (28%), and Scotland (22%). In England, the North East has the highest percentage of people struggling, with 4 in 10 residents affected. Even in London, the high costs impact 1 in 4 adults.

In response to these challenges, Britons are making significant adjustments:

  • 53% have cut back or delayed spending on smaller items like eating out, entertainment, subscriptions, clothing, toys, books, etc.;
  • 52% have reduced household energy consumption;
  • 48% have decreased their grocery spending;
  • 41% have scaled back or postponed major expenditures, such as holidays, cars, and weddings;
  • 26% are working longer hours, taking on overtime, or pursuing additional jobs to earn extra income.

The British also made changes on the financial side. One in four adults has been forced to dip into their savings or investments to cover daily expenses. Moreover, 44% have stopped saving or investing entirely or have reduced their savings and investments—a 4% increase compared to 2023.

The lack of investment is another critical factor contributing to the decline in purchasing power. It is estimated that 13 million UK residents hold £430 billion in cash deposits but do not invest. The reasons? Seventy-four percent say they cannot compare investment products effectively, and 43% are afraid of losing their money.

A lack of knowledge and fear are preventing many savers from taking advantage of an important opportunity: preserving or increasing their purchasing power in the long term.
