Nathan Johnson: The Democrat Who Wrote the Registry
The Texas Bitcoin record is usually told as a Republican story, and most of its names are. This is the page for the other half. A Dallas litigator with a physics degree took a Senate seat from Don Huffines in 2018, sat down on the committee that owns the grid, and in 2023 wrote the one mining bill the industry could accept – the registry that made the mines visible to ERCOT – on the same day his Republican colleague wrote the cap it could not. Two years later he argued the donation clause out of the state's Bitcoin reserve in committee, then voted for the reserve on the floor while the senator who would soon buy its coins voted no. He is now the Democratic nominee for attorney general. The registry, the clause, and the roll call are the record.

The short answer
Nathan Johnson is the Democratic state senator from Dallas who authored Senate Bill 1929, the 2023 Texas law requiring Bitcoin mining facilities above 75 megawatts to register with the Public Utility Commission. In Senate District 16 since 2019, he led the opposition to private donations in Senate Bill 21, the Texas Strategic Bitcoin Reserve, then voted for the bill on March 6, 2025. He is the 2026 Democratic nominee for Texas attorney general.

From the upset to the registry
2018 → 2026- The path
The upset: Johnson over Huffines
A Dallas business litigator with a physics degree - and a composing credit on the Funimation dub of Dragon Ball Z - unseats Senator Don Huffines by eight points, 54.13% to 45.87%, the first Democrat to hold Senate District 16 in more than three decades. Republicans' majority drops from 20 to 19. Huffines will resurface eight years later as the comptroller holding the state's Bitcoin. [3][2]
- The path
Business and Commerce
Sworn in January 8, 2019, Johnson lands on the Business and Commerce Committee, the panel that owns the grid. After Winter Storm Uri in 2021 the grid becomes his subject; by 2023 every Texas mining and reserve bill will cross his desk there. [1][2]
- The registry
SB 1929: the registry
One day after Kolkhorst files her cap, Johnson files the registry: any virtual currency mining facility over 75 megawatts of interruptible load registers with the Public Utility Commission within one business day of its power agreement, with its location and five years of anticipated demand, and the commission may hand the data to ERCOT. The Senate Research Center's analysis names the problem plainly - "ERCOT's inability to see or control the behavior" of large flexible loads. Senator Menéndez signs on. [4][5][6]
- The registry
Two bills pass the Senate the same day
Business and Commerce sends both bills out 11–0 on April 4; the Senate passes Kolkhorst's SB 1751 30–1 and Johnson's SB 1929 on April 12. The industry has already chosen: the registry it can live with, the cap it cannot. [4][7]
- The registry
His bill survives the House. Hers does not.
House State Affairs, where SB 1751 sits unheard, reports SB 1929 out 13–0 on May 3; the House passes it May 22 with Representative Dean as sponsor; the Senate concurs May 27; Abbott signs it June 9, effective September 1. CoinDesk's headline is the session in one line: two bills passed, one halted. Texas gets a registry and no cap. [4][8]
- The registry
"Every assumption we've made ... is now called into question"
ERCOT's Pablo Vegas tells Business and Commerce that peak demand could go from about 85,000 megawatts to 150,000 by 2030, with data centers and miners more than half the growth. Johnson: the projection has "huge policy implications, and every assumption we've made in the last four years is now called into question once again" - the arrival of "a completely new economy really in Texas, and certainly a new grid." Patrick, the same week: no "Wild Wild West of data centers and crypto miners." [9][10][11]
- The registry
The rule, seventeen months later
The Public Utility Commission adopts the registration rule his statute required: mines over 75 megawatts file location, ownership, and annual demand, with penalties of up to $25,000 per violation per day and the data held off the public record. The Texas Blockchain Council calls it "appropriate and far less invasive than what the Federal Government attempted" - the federal survey the council had sued to stop. [12]
- The reserve
"Billionaire tech bros owning a branch of the state government"
Business and Commerce hears Schwertner's reserve. Johnson goes after the donation clause: "If someone decides to give $10 billion to the state, they're creating a market for themselves" and could "manipulate the market using the imprimatur of the state. I don't want the state to be a tool of an investor." Schwertner strips the clause; the committee votes 10–0. The reserve that emerges is state money only. [13][14][17]
- The reserve
He votes yes. Hancock votes no.
The Senate passes SB 21 25–5. The journal records Johnson among the yeas with Eckhardt, Menéndez, and West; the five nays are Creighton, Gutierrez, Hall, Nichols - and Kelly Hancock, the senator who eight months later, as acting comptroller, will buy the reserve's first Bitcoin. The Democrat who edited the bill voted for it; the Republican who would execute it voted against. [15]
- The reserve
The clause comes back, and dies again
The House restores donations, limited to Texans, and passes the bill 101–42. Johnson's office says he will vote against concurring. The Senate declines the House version on May 25; conferees are named May 27; the report adopted May 29 removes the donation clause for good. Abbott signs June 20. The same afternoon he signs SB 6, the large-load law that takes his 75-megawatt registry and adds interconnection standards and emergency curtailment for every load that size. [16][17][18]
- The watch
The attorney general bid
Johnson launches a campaign for attorney general - "for a long time, the attorney general's office has been used essentially as a party apparatus" - the first major Democrat in the race to succeed Ken Paxton. He keeps his Senate seat through the campaign. [19][20]
- The watch
The nomination
Johnson leads the Democratic primary with 48.1%, then wins the runoff over Joe Jaworski with 60.5% on May 26. "Attorneys General are supposed to make sure that the competitive market is competitive," he says. He faces Republican Senator Mayes Middleton on November 3, 2026 - a colleague from Business and Commerce and a coauthor of SB 6. [21][2][22][18]
Who is Nathan Johnson, and why is he in this cluster?
Because he is the only member of it who is a Democrat, and because two of the record's load-bearing facts are his. Johnson is a Fort Worth native – physics at Arizona, law at Texas, a business and bankruptcy litigator, and, in another life, the composer of music for the Funimation dub of Dragon Ball Z – who in November 2018 unseated Senator Don Huffines by eight points in a district Republicans had held for three decades.[2][3] He took a seat on Business and Commerce, the committee through which every Texas mining and reserve bill has since passed.[1] The man he beat is on Don Huffines and Bitcoin, holding the state's coins as comptroller; the chairman of the committee is on Charles Schwertner and Bitcoin. This is the member who made the mines visible and the reserve smaller.
What is SB 1929, and why did it pass when SB 1751 didn't?
Because it asked the industry for information, not money. The two bills were filed a day apart in March 2023 from the same committee and the same interim record: the Senate Research Center's analysis of Johnson's bill names the problem as “ERCOT's inability to see or control the behavior” of large flexible loads – data centers, crypto mines, hydrogen – over 75 megawatts.[6] SB 1929 answers the seeing: a mining facility expecting more than 75 megawatts of interruptible load registers with the Public Utility Commission within one business day of its power agreement, with its location and five years of anticipated demand, and the commission may pass the data to ERCOT.[5] No cap, no abatement ban, no penalty in the statute. Both bills cleared Business and Commerce 11–0 and passed the Senate on April 12; in the House, State Affairs reported his out 13–0 on May 3 and never heard hers.[4][7] Abbott signed SB 1929 on June 9, 2023.[4] CoinDesk's headline was the whole session: two bills passed, one halted.[8] The bill that halted, and the senator who wrote it, are on Lois Kolkhorst and Bitcoin; the industry that chose between them is on Lee Bratcher and Bitcoin.
What did the registry become?
A rule, and then the state's large-load policy. The Public Utility Commission took seventeen months to adopt the registration rule his statute required – November 21, 2024 – and made it heavier than the bill: location, ownership, and annual demand, penalties of up to $25,000 per violation per day, the filings held off the public record.[12] The Texas Blockchain Council called the rule “appropriate and far less invasive than what the Federal Government attempted,” the federal survey it had sued to stop.[12] By then the number the registry was built to capture had exploded: at Johnson's committee on June 12, 2024, ERCOT's Pablo Vegas said peak demand could go from about 85,000 megawatts to 150,000 by 2030, with data centers and miners more than half of it.[9] Johnson's reaction was the sentence the hearing is remembered for: “huge policy implications, and every assumption we've made in the last four years is now called into question once again” – “a completely new economy really in Texas, and certainly a new grid.”[10][11] In 2025 the Legislature answered with SB 6, which kept his 75-megawatt line and gave ERCOT interconnection standards and emergency curtailment over every load above it; it passed his committee 10–0 and was signed June 20, 2025.[18] The mines the registry counts are on the Texas mining map.
What did Johnson do to the Texas Bitcoin reserve?
He cut the donation clause, and then he voted for what was left. Schwertner's reserve, as filed, let the public give Bitcoin to the state. In committee on February 18, 2025 Johnson went after it: “If someone decides to give $10 billion to the state, they're creating a market for themselves” and could “manipulate the market using the imprimatur of the state. I don't want the state to be a tool of an investor. I would want this to be limited to just state allocations. I don't want billionaire tech bros owning a branch of the state government.”[14][13] Schwertner removed the clause; the committee voted 10–0.[14][17] On March 6 the Senate passed SB 21 25–5, and the journal records Johnson among the yeas – with Eckhardt, Menéndez, and West – while the five nays were Creighton, Gutierrez, Hall, Nichols, and Kelly Hancock, the senator who eight months later, as acting comptroller, would buy the reserve's first Bitcoin.[15] When the House restored donations on May 21, limited to Texans, his office said he would vote against concurring; the Senate declined the House version on May 25, and the conference report adopted May 29 removed the clause for good.[16][17] The reserve as enacted holds appropriated state money and nothing else, which is the shape he asked for. The law as it operates is on the Texas Strategic Bitcoin Reserve reference; the man who bought the coins, and voted no, is on Kelly Hancock and Bitcoin.
The honest counterweight: the light registry, the yes vote, and the exit
Three things. First, the registry is light. Johnson's statute set the line at 75 megawatts, not the 10 Kolkhorst proposed; wrote no penalty; and left enforcement to a rule that took seventeen months to arrive.[5][12] Miners under 75 megawatts – most sites by count – are invisible to it. The Blockchain Council's endorsement of the rule is the tell: it was the regulation the regulated preferred. Second, the vote. The senator who warned against the state becoming “a tool of an investor” voted to put ten million dollars of general revenue into the investment, against the position of Texans for Fiscal Responsibility on his right and five of his colleagues, one of them a Democrat.[15] He can say, accurately, that he fixed the bill's worst clause and then honored the committee's work; a critic can say he narrowed the reserve and then bought it. Third, the exit. He is leaving the chamber to run for attorney general, an office whose consumer-protection docket – the kiosk scams the Legislature twice failed to regulate among them – he has not addressed in a campaign about restoring “faith and confidence” in the office itself.[19][20][23]
The fair reading, from a site that is bullish on the industry he registered: the light registry was the right registry, and the state proved it by keeping his number when it wrote SB 6. A cap would have driven flexible load off the grid; a register let ERCOT plan for it, and the industry's willingness to comply is evidence the line was drawn where it should be. The yes vote is a legislator finishing a bill he had improved, which is how the chamber is supposed to work and why the reserve passed with Democratic votes. The open question is the one the attorney general's race will answer: whether the senator who wanted the mines visible and the donors kept out brings the same instinct to the office that polices the market.
Where does the Johnson record stand today?
As of September 2026: SB 1929 is law and its rule is in force, the reserve he narrowed holds ten million dollars of state money and no donations, and he is the Democratic nominee for attorney general – 48.1% in the March 3 primary, 60.5% in the May 26 runoff – against Republican Senator Mayes Middleton, a Business and Commerce colleague and SB 6 coauthor, on November 3.[21][22][18] He holds Senate District 16 through the campaign.[1] The 90th Legislature convenes January 12, 2027 with the large-load question he named in June 2024 as its central grid fight, and either with him back on Business and Commerce or in the office across the street. The cap that died beside his registry is on Lois Kolkhorst and Bitcoin; the statute-by-statute record is on the Texas Bitcoin law timeline. This page is the Democrat who wrote the part that passed.
Frequently asked questions
Who is Nathan Johnson?
