Blockchain startup Block.one has launched version 1.0 of its open source EOSIO blockchain software, which will enable businesses to rapidly build and deploy high-performance and high-security blockchain-based applications.

The company on Friday, June 01, concluded its year-long ICO in which it raised $4.15 billion – thereby becoming the most successful ICO till date, surpassing Telegram at ICO at $1.7 billion. However, reports suggest that the ICO has also been the target of hackers.

In an official statement on the matter, Block.one said that its email support system Zendesk was temporarily breached last month.

“This message is to inform you that several members of the EOSIO community received a phishing email on May 27 that included a link to a scam website claiming to be able to register EOS Tokens ahead of the end of the EOS Token distribution. Some of these emails came from the Block.one Zendesk support system, which was temporarily breached when the message was sent,” the statement reads.

The company said that it is investigating the matter and has temporarily shut down its Zendesk system, adding:

“We believe that the sender had access to certain Block.one systems and may have seen emails sent to or from email addresses related to Block.one and its affiliates. Through that access, the sender may have seen personal information if it was communicated in an email.”

In a detailed report, Fortune listed a number of such phishing attempts which have been collecting considerable amounts from unsuspecting victims. The amount lost to these scam websites ranges from as low as $10,000 to over $100,000.

Launch of $50M EOSIO Fund

Block.one last week announced that it has partnered with SVK Crypto, a London-based investor in blockchain technologies, to launch a new $50 million fund to accelerate the growth and development of the EOSIO blockchain ecosystem.

The startup said that the fund is the fifth injection of capital through Block.one’s EOS VC initiative. The fund will invest in projects that are building on the EOSIO blockchain platform, with a focus on decentralized applications (DAPPs) for social media, data ownership, data control, technology platforms, supply chains and logistics.

EOS/USD jumped on the launch of EOSIO software to $15.74 levels and is currently trading at $14.21 levels at the time of writing (Binance).
