SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-88002; File No. SR-BOX-2019-19]


Self-Regulatory Organizations; BOX Exchange LLC; Notice of Filing 
of Amendment No. 1 and Order Instituting Proceedings To Determine 
Whether To Approve or Disapprove a Proposed Rule Change, as Modified by 
Amendment No. 1, To Adopt Rules Governing the Trading of Equity 
Securities on the Exchange Through a Facility of the Exchange Known as 
the Boston Security Token Exchange LLC

January 16, 2020.
    On September 27, 2019, BOX Exchange LLC (``Exchange'' or ``BOX'') 
filed with the Securities and Exchange Commission (``Commission''), 
pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Exchange Act'') \1\ and Rule 19b-4 thereunder,\2\ a proposed rule 
change to adopt rules governing the listing and trading of equity 
securities that would be NMS stocks on the Exchange through a facility 
of the Exchange known as the Boston Security Token Exchange LLC 
(``BSTX''). The proposed rule change was published for comment in the 
Federal Register on October 18, 2019.\3\ On November 29, 2019, pursuant 
to Section 19(b)(2) of the Exchange Act,\4\ the Commission designated a 
longer period within which to approve the proposed rule change, 
disapprove the proposed rule change, or institute proceedings to 
determine whether to approve or disapprove the proposed rule change.\5\ 
On December 26, 2019, the Exchange filed Amendment No. 1 to the 
proposed rule change, which amended the proposed rule change as 
originally filed.\6\ The Commission has received one comment letter on 
the proposed rule change.\7\ The Commission is publishing this notice 
and order to

[[Page 4041]]

solicit comments on the proposed rule change, as modified by Amendment 
No. 1, from interested persons and to institute proceedings pursuant to 
Section 19(b)(2)(B) of the Exchange Act \8\ to determine whether to 
approve or disapprove the proposed rule change, as modified by 
Amendment No. 1.

or disapprove, or institute proceedings to determine whether to 
approve or disapprove, the proposed rule change.
    \6\ In Amendment No. 1, the Exchange revised the proposal to: 
(1) Adopt listing standards that are similar to those of NYSE 
American, rather than quantitative listing standards that are 20% 
lower than those of NYSE American as initially proposed; (2) remove 
the requirement that, for a period of one year from the commencement 
of trading in security tokens on BSTX, non-BSTX Participants must 
obtain a wallet address from the Exchange and agree to report their 
end-of-day security token balances to BSTX; (3) provide for an 
omnibus wallet address to which the Exchange would instruct Wallet 
Managers to allocate unreported end-of-day balances for a given type 
of security token, resulting either from security tokens held by 
non-BSTX Participants who are not subject to the end-of-day balance 
reporting requirement or from any missing end-of-day balance reports 
among BSTX Participants; (4) state that a BSTX Participant who fails 
to obtain a wallet address prior to acquiring a position in a 
security token, fails to report the end-of-day balances in a timely 
manner, or inaccurately reports such balances would be subject to 
disciplinary action; (5) add additional listing requirements for 
security tokens issued by affiliates of the Exchange; (6) require at 
least three market makers upon initial listing for a security token 
that does not utilize a designated market maker (``DMM''); (7) state 
that the Ethereum blockchain serves as ancillary records that would 
not create or convey any ownership of security tokens or shareholder 
equity in the issuer; and (8) make technical and conforming changes. 
See text accompanying infra note 12 for the Exchange's definition of 
``security tokens,'' infra note 15 for the definition of ``BSTX 
Participant,'' and infra note 18 for the definition of ``Wallet 
Manager.'' When the Exchange filed Amendment No. 1 to BOX-2019-19, 
it also submitted the text of the partial amendment as a comment 
letter to the filing, which the Commission made publicly available

I. Summary of the Proposal, as Modified by Amendment No. 1

    As described in the Notice and Amendment No. 1,\9\ the Exchange 
proposes to adopt rules governing the trading of equity securities 
through a facility of the Exchange known as BSTX.\10\ BSTX proposes to 
operate a fully automated, price-time priority execution system to 
trade equity securities that are NMS stocks and meet BSTX listing 
standards.\11\ These securities would have ancillary records of 
ownership reflecting certain end-of-day security token balances as 
reported by market participants that would be created and maintained 
using distributed ledger technology (such securities to be referred to 
as ``security tokens'').\12\ According to the Exchange, official 
records of security ownership would be maintained by participants at 
The Depository Trust Company (``DTC''), and attribution of a security 
token on the Ethereum blockchain would not convey ownership of 
shareholder equity in the issuer.\13\
---------------------------------------------------------------------------

    \9\ See Notice, supra note 3; Amendment No. 1, supra note 6.
    \10\ See Notice, supra note 3, 84 FR at 56022.
    \11\ See id.
    \12\ See id.
    \13\ See id. at 56026.
---------------------------------------------------------------------------

    According to the Exchange, security tokens would have their 
ancillary record of ownership recorded on the Ethereum blockchain using 
a protocol standard determined by BSTX (the ``BSTX Security Token 
Protocol'').\14\ The Exchange proposes that each BSTX Participant \15\ 
would be required to establish, either directly or through a carrying 
firm, a whitelisted wallet address to which its end-of-day security 
token ownership balances may be recorded.\16\ The Exchange proposes 
that each business day, each BSTX Participant would be required to 
report to BSTX certain end-of-day security token ownership balances in 
a manner and form acceptable to BSTX.\17\ The Exchange would then, in 
coordination with a Wallet Manager,\18\ cause the Ethereum blockchain 
to be updated as an ancillary recordkeeping mechanism to reflect 
changes in ownership of security tokens.\19\ According to the Exchange, 
non-BSTX Participants that may trade security tokens would not be 
subject to the requirement to obtain a wallet address or to the end-of-
day ownership reporting requirements.\20\
---------------------------------------------------------------------------

    \14\ See id. at 56025.
    \15\ A ``BSTX Participant'' would be a participant that is 
authorized to trade security tokens on the Exchange. See proposed 
BSTX Rule 17000(a)(11).
    \16\ See Notice, supra note 3, 84 FR at 56027. According to the 
Exchange, a whitelisted wallet address would be a permissioned 
number associated with a particular market participant to which 
security tokens may be sent. The Registry Smart Contract, which is 
an ancillary smart contract within the BSTX Security Token Protocol, 
contains a list of whitelisted addresses. See id. at 56026-27.
    \17\ See id. at 56027.
    \18\ The Exchange proposes to define a ``Wallet Manager'' as a 
party approved by BSTX to operate software compatible with the BSTX 
Security Token Protocol. See proposed Rule 17000(a)(31). According 
to the Exchange, the Wallet Manager would act as a third-party 
service provider for the Exchange that would facilitate establishing 
wallet addresses and updating the Ethereum blockchain. See Notice, 
supra note 3, 84 FR at 56027 n.44.
    \19\ See Notice, supra note 3, 84 FR at 56027-28.
    \20\ See Amendment No. 1, supra note 6, at 5.
---------------------------------------------------------------------------

    According to the Exchange, to account for instances in which a BSTX 
Participant fails to report or inaccurately reports its end-of-day 
ownership balance and the position of security tokens held by non-BSTX 
Participants who are not subject to the end-of-day ownership reporting 
requirement, the Exchange would require the Wallet Mangers to allocate 
all such unreported security token balances for a given security token 
to a single omnibus wallet address.\21\ The Exchange states that the 
Ethereum blockchain would display security token balances that would 
reflect end-of-day ownership balances reported to BSTX pursuant to 
proposed BSTX Rule 17020 \22\ and a balance allocated to the omnibus 
wallet address for any type of security token for which the sum of the 
reported positions is less than the number of security tokens known by 
the Exchange to be issued and outstanding. Thus, according to the 
Exchange, the Ethereum blockchain may not reflect the precise 
distribution of a security token among holders, and may also display 
inaccurate information to the extent that BSTX Participants 
inaccurately report their end-of-day ownership balances to BSTX.\23\
---------------------------------------------------------------------------

    \21\ See id. at 6.
    \22\ Proposed BSTX Rule 17020 sets forth the proposed end-of-day 
reporting requirements for BSTX Participants. See proposed BSTX Rule 
17020.
    \23\ See Amendment No. 1, supra note 6, at 6.
---------------------------------------------------------------------------

    The Exchange proposes that security tokens would be only eligible 
for trading on another national securities exchange if that exchange is 
able to support trading in security tokens \24\ and has in effect rules 
providing for the trading of security tokens on that exchange, 
including rules requiring that exchange members obtain a wallet address 
compatible with the BSTX Security Token Protocol and adopt some 
mechanism to report end-of-day security token ownership balances to 
BSTX.\25\
---------------------------------------------------------------------------

    \24\ See Notice, supra note 3, 84 FR at 56029.
    \25\ See id.
---------------------------------------------------------------------------

    The Exchange also proposes rules for participation on BSTX, 
business conduct for BSTX Participants, financial and operational rules 
for BSTX Participants, supervision, trading practices, discipline, 
trading rules, and market making.\26\ In addition, the Exchange 
proposes listing standards that, according to the Exchange, are similar 
to the listing standards of NYSE American.\27\ The Exchange proposes 
that these listing standards would also specify that all listed 
security tokens must comply with the BSTX Security Token Protocol.\28\
---------------------------------------------------------------------------

    \26\ See id. at 56030-43. The trading rules that the Exchange 
proposes include provisions for primary distributions of securities 
to be made through the Exchange, including using an auction process. 
See id. at 56035-36.
    \27\ See Amendment No. 1, supra note 6, at 10-11.
    \28\ See Notice, supra note 3, 84 FR at 56025.
---------------------------------------------------------------------------

    According to the Exchange, all transactions in security tokens 
would clear and settle in accordance with the rules, policies, and 
procedures of registered clearing agencies.\29\ The Exchange states 
that BSTX anticipates that DTC would serve as the securities depository 
for security tokens and that confirmed trades in securities tokens on 
BSTX would be transmitted to National Securities Clearing Corporation 
(``NSCC'') for clearing.\30\
---------------------------------------------------------------------------

    \29\ See id. at 56023.
    \30\ See id.
---------------------------------------------------------------------------

II. Summary of the Comment

    To date the Commission has received one comment letter on the 
proposal.\31\ The commenter notes that the proposal was only recently 
brought to its attention because it did not anticipate that a filing by 
an options exchange to create a facility could impact the U.S. equities 
markets.\32\ The commenter expresses concern that the approval of the 
proposal ``could be a significant change for the equities market.'' 
\33\ The

[[Page 4042]]

commenter requests an extension of the comment period to consider the 
proposal, particularly on the implications of the characterization of 
security tokens as NMS stocks, the use of blockchain, and the potential 
impact on unlisted trading privileges.\34\
---------------------------------------------------------------------------

    \31\ See SIFMA Letter, supra note 7.
    \32\ Id. at 2.
    \33\ Id. The commenter's letter also references another filing 
by the Exchange, SR-BOX-2019-37, which also relates to the 
commencement of operations of BSTX. Id. at 1 (referencing Securities 
Exchange Act Release No. 87868 (December 30, 2019), 85 FR 345 
(January 3, 2020) (SR-BOX-2019-37) (``BSTX Corporate Governance 
Proposal'')). With the BSTX Corporate Governance Proposal, BSTX 
proposes the corporate governance documents for the BSTX facility, 
and describes the proposed initial ownership structure for the 
facility, which would be 50% owned by BOX Digital Markets LLC, a 
subsidiary of BOX Holdings Group LLC--an affiliate of the Exchange, 
and 50% owned by tZERO Group, Inc., an indirect subsidiary of 
Overstock.com, Inc. See id. The commenter also requests more time to 
provide feedback on the BSTX Corporate Governance Proposal. See

III. Proceedings To Determine Whether To Approve or Disapprove SR-BOX-
2019-19 and Grounds for Disapproval Under Consideration

    The Commission is instituting proceedings pursuant to Section 
19(b)(2)(B) of the Exchange Act \35\ to determine whether the proposed 
rule change should be approved or disapproved. Institution of such 
proceedings is appropriate at this time in view of the legal and policy 
issues raised by the proposed rule change. Institution of proceedings 
does not indicate that the Commission has reached any conclusions with 
respect to any of the issues involved. Rather, as described below, the 
Commission seeks and encourages interested persons to provide 
additional comment on the proposed rule change to inform the 
Commission's analysis of whether to approve or disapprove the proposed 
rule change.

---------------------------------------------------------------------------

    Pursuant to Section 19(b)(2)(B) of the Exchange Act,\36\ the 
Commission is providing notice of the grounds for disapproval under 
consideration:
---------------------------------------------------------------------------

    \36\ Id.
---------------------------------------------------------------------------

     Whether the Exchange has demonstrated how the proposal is 
consistent with Section 6(b)(1) of the Exchange Act, which requires, 
among other things, that a national securities exchange be so organized 
and have the capacity to be able to carry out the purposes of the 
Exchange Act and to comply, and enforce compliance by its members and 
persons associated with its members, with the provisions of the 
Exchange Act, the rules and regulations thereunder, and the rules of 
the Exchange; \37\
---------------------------------------------------------------------------

    \37\ 15 U.S.C. 78f(b)(1).
---------------------------------------------------------------------------

     Whether the Exchange has demonstrated how the proposal is 
consistent with Section 6(b)(5) of the Exchange Act, which requires, 
among other things, that the rules of a national securities exchange be 
designed to prevent fraudulent and manipulative acts and practices, to 
promote just and equitable principles of trade, to foster cooperation 
and coordination with persons engaged in regulating, clearing, 
settling, processing information with respect to, and facilitating 
transactions in securities, to remove impediments to and perfect the 
mechanism of a free and open market and a national market system, and 
to protect investors and the public interest, and not be designed to 
permit unfair discrimination between customers, issuers, brokers, or 
dealers; \38\
---------------------------------------------------------------------------

    \38\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

     Whether the Exchange has demonstrated how the proposal is 
consistent with Section 6(b)(7) of the Exchange Act, which requires 
that the rules of the exchange provide a fair procedure for the 
prohibition or limitation by the exchange of any person with respect to 
access to services offered by the exchange; \39\
---------------------------------------------------------------------------

    \39\ 15 U.S.C. 78f(b)(7).
---------------------------------------------------------------------------

     Whether the Exchange has demonstrated how the proposal is 
consistent with Section 6(b)(8) of the Exchange Act, which requires 
that the rules of the exchange do not impose any burden on competition 
not necessary or appropriate in furtherance of the purposes of the 
Exchange Act; \40\
---------------------------------------------------------------------------

    \40\ 15 U.S.C. 78f(b)(8).
---------------------------------------------------------------------------

     Whether the Exchange has demonstrated how the proposal is 
consistent with Section 11A of the Exchange Act, which provides the 
Commission's authority to establish and maintain a national market 
system; \41\
---------------------------------------------------------------------------

    \41\ 15 U.S.C. 78k-1.
---------------------------------------------------------------------------

     Whether the Exchange has demonstrated how the proposal is 
consistent with Section 12 of the Exchange Act, which provides, among 
other things, certain requirements that a national securities exchange 
must comply with to extend unlisted trading privileges to securities 
originally listed on another national securities exchange; \42\ and
---------------------------------------------------------------------------

    \42\ 15 U.S.C. 78l.
---------------------------------------------------------------------------

     Whether the Exchange has demonstrated how the proposal is 
consistent with Section 17A of the Exchange Act, which provides, among 
other things, the Commission's authority to establish linked or 
coordinated facilities for the clearance and settlement of transactions 
in securities.\43\
---------------------------------------------------------------------------

    \43\ 15 U.S.C. 78q-1.
---------------------------------------------------------------------------

    Under the Commission's Rules of Practice, the ``burden to 
demonstrate that a proposed rule change is consistent with the Exchange 
Act and the rules and regulations issued thereunder . . . is on the 
[SRO] that proposed the rule change.'' \44\ The description of a 
proposed rule change, its purpose and operation, its effect, and a 
legal analysis of its consistency with applicable requirements must all 
be sufficiently detailed and specific to support an affirmative 
Commission finding,\45\ and any failure of an SRO to provide this 
information may result in the Commission not having a sufficient basis 
to make an affirmative finding that a proposed rule change is 
consistent with the Exchange Act and the applicable rules and 
regulations.\46\

    The Commission is instituting proceedings to allow for additional 
consideration and comment on the issues raised herein, including as to 
whether the proposal is consistent with the Exchange Act.

IV. Procedure: Request for Written Comments

    The Commission requests that interested persons provide written 
submissions of their views, data, and arguments with respect to the 
issues identified above, as well as any other concerns they may have 
with the proposal. In particular, the Commission invites the written 
views of interested persons concerning whether the proposal, as

(``Securities Act'') or the Exchange Act, or the rules and regulations 
thereunder. Although there do not appear to be any issues relevant to 
approval or disapproval that would be facilitated by an oral 
presentation of views, data, and arguments, the Commission will 
consider, pursuant to Rule 19b-4 under the Exchange Act,\54\ any 
request for an opportunity to make an oral presentation.\55\

---------------------------------------------------------------------------

    Interested persons are invited to submit written data, views, and

proposal should be approved or disapproved by February 13, 2020. Any 
person who wishes to file a rebuttal to any other person's submission 
must file that rebuttal by February 27, 2020.
    The Commission asks that commenters address the sufficiency of the 
Exchange's statements in support of the proposal, which are set forth 
in the Notice and Amendment No. 1,\56\ in addition to any other 
comments they may wish to submit about the proposed rule change. In 
particular, the Commission seeks comment on the following questions and 
asks commenters to submit data where appropriate to support their 
views:
---------------------------------------------------------------------------

    \56\ See Notice, supra note 3; Amendment No. 1, supra note 6.
---------------------------------------------------------------------------

     What are commenters' views on the use of distributed 
ledger technology to create and maintain unofficial ancillary records 
of ownership reflecting certain end-of-day security token ownership 
balances as reported by market participants, and the use of the 
Ethereum blockchain in particular? What are commenters' views on 
whether the use of the Ethereum blockchain for an ancillary record of 
ownership is consistent with referring to the security as a ``token''? 
What are commenters' views on advantages and disadvantages of having an 
unofficial ancillary record of a security's ownership on the Ethereum 
blockchain, in addition to an official record of such security's 
ownership through DTC, including costs and benefit to investors or the 
integrity of the securities markets?
     What are commenters' views on potential discrepancies that 
may exist between the official records of ownership and the unofficial 
ancillary records maintained on the Ethereum blockchain, how erroneous 
entries of transactions on the Ethereum blockchain would be identified 
and addressed, and how the unofficial ancillary record would be updated 
after events such as dividends and stock splits? Do commenters believe 
that potential discrepancies between the official records of ownership 
and the unofficial ancillary records maintained on the Ethereum 
blockchain could pose risks to investors, other market participants, 
the securities market, or the national clearance and settlement system? 
Please explain why or why not.
     What are commenters' views on whether the ancillary 
recordkeeping mechanism is inconsistent with Section 17A(a)(2)(A)(ii) 
of the Exchange Act,\57\ which directs the Commission to facilitate the 
establishment of linked or coordinated facilities for clearance and 
settlement of securities transactions, or any other provision of the 
Exchange Act, or the rules and regulations thereunder?
---------------------------------------------------------------------------

    \57\ 15 U.S.C. 78q-1(a)(2)(A)(ii).
---------------------------------------------------------------------------

     The Exchange states that ``[p]ursuant to Rule 12f-5 under 
the Exchange Act,\58\ an exchange may not extend unlisted trading 
privileges to any security unless the national securities exchange has 
in effect rules providing for transactions in the class or type of 
security to which the exchange extends unlisted trading privileges'' 
\59\ and that to be able to extend unlisted trading privileges to BSTX-
listed security tokens, another national security exchanges would need 
rules that would ``(i) requir[e] that exchange members obtain a wallet 
address compatible with the BSTX Security Token Protocol in order to 
attribute security token balances with that exchange member; and (ii) 
adopt[] some mechanism to report end-of-day security token [ownership] 
balances to BSTX in order to facilitate updates of ownership to the 
Ethereum blockchain as an ancillary recordkeeping mechanism.'' \60\ 
What are commenters' views on how a national securities exchange 
seeking to extend unlisted trading privileges to a BSTX-listed security 
token might fulfill these requirements and whether doing so would 
impose a burden on competition that is not necessary or appropriate in 
furtherance of the purposes of the Exchange Act? Do commenters agree 
with the Exchange's assertion that the burden on another exchange of 
adopting additional rules to extend unlisted trading privileges to 
trade BSTX-listed security tokens is no different than the burden on an 
exchange that only trades equities having to first adopt rules to 
govern options trading prior to offering trading in options? \61\ Why 
or why not?

     Do commenters believe that the proposal, including the 
proposed requirement that the BSTX Participants report their end-of-day 
ownership balances to BSTX to be recorded to the Ethereum blockchain, 
is designed to remove impediments to and perfect the mechanism of a 
free and open market and a national market system for NMS stock? \62\ 
Why or why not? Do commenters believe that the proposal is in the 
public interest and appropriate for the protection of investors and is 
designed to maintain fair and orderly markets to assure, among other 
things, fair competition among brokers and dealers, among exchange 
markets, and between exchange markets and markets other than exchange 
markets; and the practicability of brokers executing investors' orders 
in the best market? \63\ Why or why not?

     Do commenters agree with the Exchange's assertion that 
requiring BSTX Participants to report their end-of-day ownership 
balances to the Exchange, while non-BSTX Participants would not be 
subject to the same requirement, would ``impose only a minimal burden 
on BSTX Participants''? \64\ Why or why not? Do commenters believe that 
the requirements imposed by the end-of-day ownership reporting 
requirements would result in a burden or impact on competition between 
BSTX Participants and non-BSTX Participants or otherwise, that would be 
necessary or appropriate in furtherance of the Exchange Act? Why or why 
not?

     What are commenters' views on the Exchange's proposal to 
disseminate end-of-day ownership information, potential inaccuracies in 
that information, how and when that information would be disseminated, 
and how market participants would have access to view this information 
on the Ethereum blockchain? What are commenters' views on any 
advantages or disadvantages with the Exchange's proposal to disseminate 
end-of-day ownership information?
     What are commenters' views on the use of an omnibus 
account to reflect discrepancies between the sum of end-of-day balances 
reported by BSTX Participants and the number of security tokens known 
by the Exchange to be issued and outstanding? Do commenters have 
concerns about how and when the balances attributed to the omnibus 
wallet address would be calculated and by whom? What are commenters' 
views on how the number of securities for a given security token 
attributed to the omnibus wallet address may change over time and the 
potential for the total number of securities for a security token 
attributed to the omnibus wallet address to exceed the number of 
disseminated whitelisted address for that security token? What are 
commenters' views on whether they would have access to the information 
necessary to differentiate the balances attributed to the omnibus 
wallet address from the balances attributed to whitelisted addresses in 
the information disseminated on the Ethereum blockchain and, if not, 
the potential for confusion by investors or other market participants?

     What are commenters' views on the proposed requirement 
that end-of-day security token balances must be reported to BSTX each 
business day when the securities depository is also open for business, 
after such time as the securities depository has completed its end-of-
day settlement process? Do commenters agree with ``BSTX's belie[f] that 
the proposed end-of-day security token balance reporting requirement 
would be consistent with authority that the Commission has already 
approved regarding furnishment of records by members of exchanges''? 
\65\ Why or why not? What are commenters' view on how the Exchange will 
enforce compliance with the end-of-day ownership reporting requirement 
on BSTX Participants?
---------------------------------------------------------------------------

    \65\ Notice, supra note 3, 84 FR at 56028.
---------------------------------------------------------------------------

     What are commenters' views on the Exchange's proposal to 
require each BSTX Participant to, either directly or through its 
carrying firm, establish a whitelisted wallet address to which its end-
of-day security token ownership balances may be recorded by contacting 
BSTX or a Wallet Manager? \66\ What are commenters' views on the 
function and activities of the Exchange Wallet Manager and how the 
Wallet Manager will assist a BSTX Participant with establishing a 
wallet address? What are commenters' views on the standard the Exchange 
will use to select a Wallet Manager, the standard that the Wallet 
Manager will use to approve or deny applications to establish a wallet 
address, Exchange's oversight of the Wallet Manager's activities, 
including the Wallet Manager's approval or denial of applications to 
establish a wallet address, and the Exchange's rules and procedures to 
ensure that a Wallet Manager does not act in an unfair or 
discriminatory manner in performing its function?
---------------------------------------------------------------------------

    \66\ See id. at 56027.
---------------------------------------------------------------------------

     What are commenters' views on whether it would be feasible 
for third parties not affiliated with BSTX to serve as a Wallet 
Manager? What are commenters' views on the Exchange's representation 
that the BSTX Security Token Protocol is based on open source code, 
that the Exchange would not require the use of a particular version of 
Wallet Manager software, and that anyone would be eligible to serve or 
operate as a Wallet Manager provided they are capable of facilitating 
effective updates to the Ethereum blockchain to reflect changes in 
security token ownership? \67\ What are commenters' views on 
competition to be a Wallet Manager and any potential for conflicts of 
interest that may arise between or among national securities exchange 
and Wallet Managers for trading BSTX-listed security tokens?
---------------------------------------------------------------------------

    \67\ See id. at 56055.
---------------------------------------------------------------------------

     While the Exchange proposes that the Exchange and Wallet 
Manager will not charge a fee for obtaining a wallet address, what are 
commenters' views on the costs that may be incurred because of the end-
of-day security token balance reporting process to investors, issuers, 
broker-dealers, including BSTX Participants and non-BSTX Participants, 
Wallet Managers, and trading centers, such as national securities 
exchanges and alternative trading systems? \68\
---------------------------------------------------------------------------

    \68\ See id. at 56046 n.286.
---------------------------------------------------------------------------

     Do commenters agree with the Exchange's assertion that 
``[o]wnership of security tokens would be able to be transferred 
without regard to the blockchain-based ancillary recordkeeping 
functionality''? \69\ Why or why not? What are commenters' views on 
whether or not having a security token attributed to a wallet address 
could mean that the holder of the wallet address has a shareholder 
equity interest in the issuer? What are commenters' views on how 
disputes over ownership of security token would be enforced by the 
Exchange or any other party?
---------------------------------------------------------------------------

    \69\ Id. at 56023.
---------------------------------------------------------------------------

     The proposed trading rules include provisions providing 
for primary distributions of securities be made through the Exchange, 
including using an auction process.\70\ Do commenters agree with the 
Exchange's assertion that the proposed method of opening trading in 
securities, including with respect to initial security token offerings, 
``provides a simple and clear method for opening transactions that is 
consistent with the protection of investors and the public interest''? 
\71\ Why are why not? Do commenters understand from the Exchange's 
proposal how primary offerings of security tokens could be made through 
the Exchange in compliance with the Securities Act, including the 
registration and prospective delivery provisions, and the related rules 
thereunder? If not, what information would be helpful? Do commenters 
understand from the Exchange's proposal how broker-dealers using the 
Exchange to engage in primary offerings of securities would be able to 
comply with their obligations under the Securities Act and the Exchange 
Act, and the respective rules thereunder? If so, please describe how a 
broker-dealer could comply.

     The Exchange states that ``NSCC already has authority 
under its rules, policies and procedures to clear certain trades on a 
T+1 or T+0 basis.'' \72\ What are commenters' views on the NSCC process 
for clearing security tokens? Do commenters believe that the Exchange 
has adequately explained why BSTX Participants may agree to shorter or 
longer settlement cycles than T+1,\73\ and the potential effects of 
such shorter or longer settlement cycles?

---------------------------------------------------------------------------

     What are commenters' views on the rules the Exchange is 
proposing for short sales of security tokens? Do commenters believe 
that the proposed short selling rules are appropriately designed for 
the ancillary recordkeeping on the Ethereum blockchain and the T+1 
reporting? Why or why not?
