2 Executives Are Leaving Blockchain Startup R3 in Management Shake-Up
R3 is carrying out an internal reorganization, resulting in the departures of head of global services Brian McNulty and chief administrative officer Lauren Carroll, CoinDesk has learned.

Distributed ledger technology provider R3 has carried out an extensive internal reorganization, resulting in the departure of two members of its management committee, CoinDesk has learned.
Brian McNulty, a managing director and head of global services, and Lauren Carroll, chief administrative officer, are leaving the company, R3 told employees at town hall meetings Friday, according to people familiar with the situation.
An R3 spokesperson confirmed the internal reorganization, which he said will include an expansive hiring program for 2019, but declined to comment on individual staff departures. Neither McNulty nor Carroll answered requests for comment by press time.
McNulty joined R3 in March 2016 when the start-up was busy onboarding consortium member banks. He had previously founded the PTDL (Post Trade Distributed Ledger) Group, a rival blockchain group which numbered around 40 members including CME Group, State Street Bank and the London Stock Exchange.
Carroll was formerly in-house counsel at ICAP before transitioning into business management roles at the electronic trading firm.
New team structure
As part of the reorganization, co-founder Todd McDonald will run a new "design" team that combines all of R3's product and marketing efforts, according to a memo CEO David Rutter sent the company's roughly 200 employees after Friday's town hall meetings.
Product management was previously in the same division as engineering, which Richard Gendal Brown will continue to lead.
The memo also outlined several other changes:
- Chief engineer James Carlyle will run a new "production" team dedicated to supporting the deployment of R3's technology at client companies.
- The general counsel's office has been merged with external affairs and placed under Charley Cooper, who has long overseen regulatory affairs and public relations for R3.
- Chief of staff Zack Kavanaugh assumed added responsibilities for recruiting, HR and business resources.
- Chief financial officer (CFO) Paul Harris will oversee a combined finance and corporate development (M&A team.
- A search is underway for a chief revenue officer (CRO) to lead the sales team. As CoinDesk reported earlier this month, Scott Grayson, R3's former chief sales officer, left in September and recently joined the blockchain services firm AlphaPoint.
In June 2018 R3 had to field media speculation that the company was running short of funds. More recently, a legal dispute with Ripple concerning a contract to purchase five billion XRP tokens was resolved.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
