Smart Contracts Create Reliable Agreements
Smart Contract: a digital agreement that is tamper-proof, because it is run on a decentralized computing network.
Allowing both parties to trust the contract’s execution,
because both can observe it, while neither of them controls it.

Overcoming Risks of New Software Delivery
We heard the same concern over and over
again: a panic over giving up control. ~Marc Benioff (Salesforce Founder)

proceeds. By purchasing LINK, you acknowledge that you understand and have no objection to these procedures and material specifications.
5. LINK Discontinuance and Conversion
(a) LINK are being created as ERC-20 or ERC-223 tokens on the Ethereum protocol. We reserve the right to migrate the ERC-20 based Tokens (the “Existing Tokens”) to another protocol, at our discretion, and to generate replacement LINK on the new protocol (the “Replacement Tokens”) in the future, should we determine, in our sole discretion, that doing so is necessary or useful to the operation of the Ecosystem.
(b) Should we decide to migrate LINK to a new protocol, we may no longer provide support for the Existing Tokens relating to the Ecosystem, the Services, or any other operational matters, except with respect to the migration process. Although Company does not at this time anticipate that it will require any Existing Token holders to convert their Existing Tokens to Replacement Tokens, Company anticipates there will be significant incentives for Existing Token owners to do so, since the practical utility of Existing Tokens will likely diminish rapidly once the Replacement Tokens are created and in use by a significant portion of Ecosystem participants. Accordingly, by accepting these Terms you acknowledge and agree that in order for you to continue to participate in the Ecosystem or obtain utility from LINK you may need to convert the LINK you purchase during the sale to Replacement Tokens in the future.
(c) Should we decide to migrate LINK to a new protocol, we will notify you by public announcement.
6. Acknowledgment and Assumption of Risks
You acknowledge and agree that there are risks associated with purchasing LINK, holding LINK, and using LINK in connection with the Services, as further disclosed and explained in Exhibit C . If you have any questions regarding these risks, please contact [email protected]. BY PURCHASING LINK, YOU EXPRESSLY ACKNOWLEDGE AND ASSUME THESE RISKS, AND ARE CERTIFYING THAT YOU DO NOT RESIDE IN AND ARE NOT A CITIZEN OF THE UNITED STATES.
7. Security
You are responsible for implementing reasonable measures for securing the wallet, vault or other storage mechanism you use to receive and hold LINK you purchase from us, including any requisite private key(s) or other credentials necessary to access such storage mechanism(s). If your private key(s) or other access credentials are lost, you may lose access to your LINK. We disclaim any responsibility for any such losses.
8. Personal Information
We may determine, in our sole discretion, that it is necessary to obtain certain information about you in order to comply with applicable laws, rules or regulations in connection with

The Smart Contract Connectivity Problem
Smart Contracts are unable to connect with external data, or any other off-chain resources on their own.
80%+ of smart contract use cases need external resources
![Page 15: Blockchain Super Conference 2018Token owners to do so, since the practical utility of Existing Tokens will likely diminish rapidly once the Replacement Tokens are created and in use](https://reader035.vdocuments.mx/reader035/viewer/2022062605/5fd4a1e90a5ddf59a75f5c5e/html5/thumbnails/15.jpg)
Blockchain Middleware Creates Connectivity
Connect Smart Contracts to critical external data, so they can include real world events.

Blockchain Middleware Creates Connectivity
Connect Smart Contracts to critical external data, so they can include real world events.
Connect Smart Contracts to widely accepted bank payments
so they can pay in local currencies.
Connect Smart Contracts from different networks to each other
for critical combined functionality.

proceeds. By purchasing LINK, you acknowledge that you understand and have no objection to these procedures and material specifications.
5. LINK Discontinuance and Conversion
(a) LINK are being created as ERC-20 or ERC-223 tokens on the Ethereum protocol. We reserve the right to migrate the ERC-20 based Tokens (the “Existing Tokens”) to another protocol, at our discretion, and to generate replacement LINK on the new protocol (the “Replacement Tokens”) in the future, should we determine, in our sole discretion, that doing so is necessary or useful to the operation of the Ecosystem.
(b) Should we decide to migrate LINK to a new protocol, we may no longer provide support for the Existing Tokens relating to the Ecosystem, the Services, or any other operational matters, except with respect to the migration process. Although Company does not at this time anticipate that it will require any Existing Token holders to convert their Existing Tokens to Replacement Tokens, Company anticipates there will be significant incentives for Existing Token owners to do so, since the practical utility of Existing Tokens will likely diminish rapidly once the Replacement Tokens are created and in use by a significant portion of Ecosystem participants. Accordingly, by accepting these Terms you acknowledge and agree that in order for you to continue to participate in the Ecosystem or obtain utility from LINK you may need to convert the LINK you purchase during the sale to Replacement Tokens in the future.
(c) Should we decide to migrate LINK to a new protocol, we will notify you by public announcement.
6. Acknowledgment and Assumption of Risks
You acknowledge and agree that there are risks associated with purchasing LINK, holding LINK, and using LINK in connection with the Services, as further disclosed and explained in Exhibit C . If you have any questions regarding these risks, please contact [email protected]. BY PURCHASING LINK, YOU EXPRESSLY ACKNOWLEDGE AND ASSUME THESE RISKS, AND ARE CERTIFYING THAT YOU DO NOT RESIDE IN AND ARE NOT A CITIZEN OF THE UNITED STATES.
7. Security
You are responsible for implementing reasonable measures for securing the wallet, vault or other storage mechanism you use to receive and hold LINK you purchase from us, including any requisite private key(s) or other credentials necessary to access such storage mechanism(s). If your private key(s) or other access credentials are lost, you may lose access to your LINK. We disclaim any responsibility for any such losses.
