EXCEPT AS SET OUT IN SECTION XIV.A (SEPARATE AGREEMENTS), THIS AGREEMENT REPRESENTS THE ENTIRE AGREEMENT CONCERNING THE FEATURES BETWEEN THE PARTIES AND IT SUPERSEDES ANY PRIOR PROPOSAL, REPRESENTATION, OR UNDERSTANDING BETWEEN THE PARTIES. BLOCKSPACE AND USER ARE HEREINAFTER JOINTLY DEFINED AS THE "PARTIES" OR INDIVIDUALLY A "PARTY".

These Terms of Use (as amended or supplemented from time to time, these "Terms") explain the terms and conditions by which you may access and/or use Blockspace's website, blockspace.forum, and the research, articles, educational materials, event summaries, videos, data, tools, software, documentation, projects, and other online properties made available through it (collectively, "Features") provided by Blockspace ("Blockspace," "we," "us," or "our").

The Blockspace Forum (the "Forum") is an open community of teams and individuals working to improve Ethereum's transaction and block construction pipeline. Blockspace operates the website and contributes to the Forum's research and events alongside the Forum's other participants. Participating in the Forum, attending a Forum event or contributing to Forum research does not make you a partner, agent or representative of Blockspace or of any other participant.

All access and use of the Features is subject to these Terms. By accessing or otherwise using the Features, you acknowledge that you have read, understood, and agree to be bound by these Terms. If you do not accept the terms and conditions of these Terms, you will not access, browse, or otherwise use the Features.

Blockspace reserves the right, at its sole discretion, to change, update, or modify portions of these Terms at any time. Blockspace will post the changes on this page and will indicate at the top of this page the date these Terms were last revised. Your continued use of the Features after the date any such changes become effective constitutes your acceptance of the new Terms. Revised Terms do not apply to any dispute that arose before they were posted. You should periodically visit this page to review the current Terms, so you are aware of any revisions. If you do not agree to abide by these or any future Terms, you will not access, browse, or use (or continue to access, browse, or use) the Features.

Third Party Services are provided for your convenience only and the availability of Third Party Services does not constitute an endorsement by Blockspace of the same. Third Party Services are not under Blockspace's control and, as such, are not considered part of our Features. Blockspace makes no representation or warranty regarding any Third Party Service, including its availability, security, or suitability for use with or in conjunction with Blockspace's Features. Any proprietary right or interest to any Third Party Service and any content provided therein belongs to that third party provider subject to any right or license you may hold to such Third Party Service. If you decide to access or use a Third Party Service, your activity is governed by the Third Party Service's terms and conditions, not by those of Blockspace. This includes all terms and policies that govern your use of GitHub, the website which hosts our Features.

Tools, dashboards, clients and other software listed in the Features are listed for information only. A listing is not an endorsement, audit, security review or recommendation. Some listed tools are developed or operated by organizations affiliated with Blockspace or with Forum contributors.

Attendance at Forum workshops, meetings and other events is subject to any registration terms, code of conduct and rules announced for that event.

II. Informational Content Only; No Advice​

A. Informational Purposes​

The research, articles, educational materials, event summaries, videos, data and other content included in the Features (the "Content") are provided for general informational and educational purposes only.

B. No Advice​

Nothing in the Content is investment, financial, trading, legal, tax, accounting or other professional advice, or a recommendation to acquire, sell, stake, delegate or hold ETH or any other digital asset, or to use any particular infrastructure, service provider, protocol or software. You should obtain advice from your own qualified advisors before making any decision.

C. No Offer​

Nothing in the Features is an offer or solicitation to buy or sell any security, digital asset or other investment, including any interest in Blockspace, or an offer of staking, validator, delegation or other services. Blockspace provides its services only under separate written agreements.

D. Accuracy and Currency​

Research and market data in this field change quickly. The Content might contain errors or omissions, might rely on data provided by third parties that Blockspace has not independently verified, and might become out of date. Proposals, designs and specifications described in the Content are at the research stage and might not be implemented or perform as described. Blockspace has no obligation to update or correct any Content.

E. Forward-Looking Statements​

Statements in the Content about future events, including protocol upgrades and their timing, adoption of mechanisms, market structure and network performance, reflect the author's expectations and assumptions at the time of writing. Actual outcomes might differ materially.

F. Views of Authors and Speakers​

Content attributed to an author, speaker or panelist reflects that person's own views and not necessarily the views of Blockspace, the Forum's other participants or that person's employer. Event summaries describe discussions in general terms. An event summary does not record any agreement or commitment by any participant, and no participant is bound to adopt any mechanism, design or practice described in it.

G. Commercial Interests​

Blockspace is a for-profit company. Some authors of the Content and some speakers at Forum events are shareholders, directors, officers, employees or contractors of Blockspace, or work for organizations that operate relays, block builders, validators or other infrastructure described in the Content. Blockspace, those individuals and those organizations might benefit commercially if mechanisms, designs, specifications or tools described in the Content are adopted. You should take those interests into account when you read the Content.

H. Operational Risk​

Relay, block builder, validator, sidecar and other infrastructure software can cause missed slots, lost rewards, penalties, slashing, failed or delayed transactions and loss of digital assets if it is defective, misconfigured or operated incorrectly. If you download, deploy or operate any software described in or made available through the Features, you are solely responsible for reviewing, testing, auditing, configuring, securing and operating it, including safeguarding any private keys, signing keys and withdrawal credentials.

I. No Reliance​

Blockspace does not assume any responsibility or duty of care to you regarding the Content. You are solely responsible for any decision you make, and for any action you take or decline to take, based on the Content.
