The California Shopper Privateness Act of 2018 (CCPA), which matches into impact on Jan. 1, 2020, has signaled a brand new push in the US to strengthen and broaden privateness rules, much like the developments seen within the European Union by means of the passage and implementation of the Normal Information Safety Regulation (GDPR).
The CCPA affords coated shoppers new privateness rights not in any other case loved right here within the U.S. Underneath the CCPA, an entity qualifying as a “enterprise” should present:
- Abbreviated disclosures relating to the private data that’s collected from or about coated shoppers (Cal. Civ. Code § 1798.100).
- Sure different expanded disclosures relating to private data collected from or about coated shoppers (id. § 1798.110(a)).
- Disclosures relating to the sale or disclosure of private data for a enterprise goal (id. § 1798.115).
- An opt-out from the “sale” of private data (id. § 1798.120).
- An opt-in requirement earlier than promoting a minor’s private data (id. § 1798.120(c)).
- The flexibility for coated shoppers to entry and/or delete private data collected from or about them (id. §§ 1798.105, 1798.100(d)).
Subjected companies should additionally implement measures to forestall discrimination in opposition to shoppers who train their rights beneath the CCPA (id. § 1798.125). Due to these new obligations, the implementation of the CCPA could result in drastic challenges for organizations which can be using blockchain expertise.
What does the CCPA imply for blockchain?
Blockchain expertise is getting used to develop options and instruments that present people a lot higher management over their information. The expertise’s usually public and immutable ledgers promise to introduce a brand new degree of transparency into how people’ information is getting used. Blockchain expertise (significantly when it’s employed in a public/permissionless surroundings) is decentralized in a fashion that always signifies that the way in which that information is saved, processed or in any other case used doesn’t essentially rely on a centralized authority or single “steward” or “controller.” In some ways, blockchain expertise upends conventional fashions of gathering and storing private information by enabling decentralization — thus eradicating third-party intermediaries.
Nevertheless, most information privateness legal guidelines, together with the CCPA, presume the operation of the normal information mannequin, which makes them tough to reconcile with a decentralized or distributed information mannequin. Thus, even supposing the CCPA aligns philosophically with lots of the targets of blockchain expertise (i.e., information integrity, cybersecurity and transparency), a number of inherent options of most blockchain applied sciences can pose compliance challenges — particularly, blockchain’s decentralized construction and the immutability of knowledge entered into the blockchain ledgers.
A lot of the uncertainty surrounding the CCPA (each typically and because it applies to blockchain expertise) stems from the statute’s broad definitions. For instance, the definition of private data encompasses “data that identifies, pertains to, describes, is able to being related to, or might moderately be linked, instantly or not directly, with a selected shopper or family.” (Id. § 1798.140(o)(1)). Regardless of requires the legislature to offer additional clarification — together with these voiced in the course of the state legal professional basic’s a number of public boards pending the passage of any extra amendments — the statute, as it’s presently written, turns into efficient on Jan. 1, 2020.
Notably, enforcement actions by the legal professional basic could also be introduced six months after the publication of ultimate rules or Jul. 1, 2020, whichever is sooner (Id. § 1798.185(c)). Civil penalties embody injunctions and fines of as much as $2,500 per violation and aggravated fines of as much as $7,500 per intentional violation. Be aware that buyers are afforded a restricted non-public proper of motion in conditions when their private data is “topic to an unauthorized entry and exfiltration, theft, or disclosure on account of the enterprise’s violation of the obligation to implement and keep cheap safety procedures and practices.”
When are blockchain companies topic to the CCPA?
The CCPA’s obligations are restricted to “companies,” that are outlined as any for-profit firm doing enterprise in California that collects private data and satisfies a minimum of one of many following thresholds:
- Receives an annual gross income in extra of $25 million.
- Yearly buys, sells, or, for industrial functions, receives or shares private data of a minimum of 50,000 California shoppers, households or units.
- Derives 50% or extra of its annual income from “promoting” California shopper private data.
Be aware that “doing enterprise” is undefined by the statute and might be construed to embody a blockchain platform with nodes that function in California or that acquire information from Californian shoppers (Id. § 1798.140(c)(1)).
Although the primary prong of the CCPA threshold take a look at is pretty self-explanatory, the second and third prongs are much less simple. The mere act of internet hosting data on a blockchain might be thought of “sharing” private data, significantly when nodes are handled as “units” beneath the second prong of the take a look at. For instance, the existence of 500 nodes on a blockchain community that every one keep a duplicate of the ledger could represent “sharing” beneath the statute (though there’s presently no regulatory steerage on this matter).
The definition of “promoting” can be very broad. It contains “renting, releasing, disclosing, disseminating, making out there, transferring, or in any other case speaking orally, in writing, or by digital or different means” private data for “different priceless consideration.” (Cal. Civ. Code § 1798.140(t)(1)). What constitutes “different priceless consideration” stays unspecified.
Due to this fact, it seems from the facial language of the statute that blockchain corporations might be thought of to be “promoting” private data just by internet hosting and working a blockchain platform by means of which individuals and entities can alternate private data — significantly if the blockchain firm expenses a price (whether or not in tokens operable on the blockchain or another type of exterior consideration) to entry the blockchain or derives different “priceless consideration” from the internet hosting and working of a platform that facilitates private data alternate.

Equally, it’s attainable that node operators or miners in a blockchain surroundings who obtain tokens or cryptocurrency in alternate for performing transaction validation or ledger affirmation companies to the community could be equally thought of to be “promoting” as a result of they’re “speaking […] by digital or different means” private data that’s written to the blockchain. If a coated enterprise is discovered to be “promoting” private data, extra discover, disclosure and different obligations will apply — even when the enterprise has not engaged in what would historically be thought of a “sale” for financial consideration.
Extra, whereas pseudonymization could assist obfuscate information, it doesn’t render the topic information nonpersonal. As a result of the statute applies to non-public data that’s “able to being related to, or might moderately be linked, instantly or not directly” with the person, such methods could show inadequate because of the danger of reidentification.
How can a blockchain enterprise greatest tackle compliance with the CCPA?
Companies that deploy blockchain expertise ought to fastidiously contemplate the extent to which private data is written to blockchain-based ledgers and whether or not there are methods to mitigate the issues that come up from this appertaining to the calls for and necessities of the CCPA.
For instance, companies may contemplate storing private data off-chain (i.e., not on the blockchain) whereas utilizing the ledger to trace and mediate entry to the private data. Such a answer might allow the enterprise to instantly reference the off-chain private data for reporting obligations beneath the CCPA whereas sustaining the integrity of its ledger, and with out essentially placing the information on-chain, such that the enterprise couldn’t delete that information upon request. On this state of affairs, deletion is easy: By merely taking the information off-chain, any immutable references on-chain turn into references to nonexistent information and are rendered meaningless.
Nevertheless, off-chain workarounds can add undesirable complexity that’s at odds with many blockchain platforms’ targets of simplicity and transparency. Moreover, these workarounds usually fail to resolve the safety considerations offered by having parallel information sources in the established order that blockchain-based options so elegantly tackle.
If an off-chain answer is impractical, blockchain companies might contemplate taking all information obfuscation steps out there to depersonalize the information as a lot as attainable (e.g., making use of salting, encryption and hashing methods to all on-chain information). Nevertheless, information on the blockchain is nearly at all times related to a ledger’s public key (i.e., ledger tackle) and is subsequently related to the particular person or entity that was including information to that tackle. Accordingly, public keys might be deemed “private data” beneath the CCPA to the extent that they belong to or might be tied to a California shopper.
Lastly, companies ought to start taking steps to adjust to the CCPA as quickly as attainable: In a 2018 dialog at Perkins Coie LLP, Eleanor Blume, the particular assistant to the California Workplace of the Lawyer Normal, emphasised that corporations could be evaluated on their CCPA compliance partially by the preventative measures they took in 2019.
