Sec. 5. Definitions. As used in this Act:
"Blockchain" means an electronic record created by the use of a decentralized method by multiple parties to verify and store a digital record of transactions which is secured by the use of a cryptographic hash of previous transaction information.
"Cryptographic hash" means a mathematical algorithm which performs a one-way conversion of input data into output data of a specified size to verify the integrity of the data.
"Electronic" means relating to technology having electrical, digital, magnetic, wireless, optical, electromagnetic, or similar capabilities.
"Electronic record" means a record created, generated, sent, communicated, received, or stored by electronic means, including a blockchain or a smart contract.

(205 ILCS 730/10)
Sec. 10. Permitted use of blockchain.
(a) A smart contract, record, or signature may not be denied legal effect or enforceability solely because a blockchain was used to create, store, or verify the smart contract, record, or signature.
(b) In a proceeding, evidence of a smart contract, record, or signature must not be excluded solely because a blockchain was used to create, store, or verify the smart contract, record, or signature.
(c) If a law requires a record to be in writing, submission of a blockchain which electronically contains the record satisfies the law.

Sec. 15. Limitations to the use of blockchain.
(a) If parties have agreed to conduct a transaction by use of a blockchain and a law requires that a contract or other record relating to the transaction be in writing, the legal effect, validity, or enforceability of the contract or other record may be denied if the blockchain containing an electronic record of the transaction is not in a form that is capable of being retained and accurately reproduced for later reference by all parties or other persons who are entitled to retain the contract or other record.
(b) Except as otherwise provided in subsection (f), if a law other than this Act requires a record to be posted or displayed in a certain manner, to be sent, communicated, or transmitted by a specified method, or to contain information that is formatted in a certain matter, the use of a blockchain to post, display, send, communicate, transmit, or store such a record does not satisfy the requirement of the other law.
(c) If a person inhibits the ability of another person to store or retrieve information contained in a blockchain, such information is not enforceable by the person who inhibited the storage or retrieval.
(d) Regardless of whether a smart contract was used to establish the relationship between the parties to an agreement, a requirement that a notice or an acknowledgment or other response to a notice be in writing is not satisfied by providing or delivering the notice or recording an acknowledgment or other response to the notice by the use of a blockchain if the notice is a notice of:
(e) A requirement that a document be in writing is not satisfied by the use of a blockchain if the document is required to accompany any transportation or handling of hazardous materials, pesticides, or other toxic or dangerous materials.
