Bitcoin for Hacking

Oct 21, 2014 • Lezen duurt 1 minuten

Coinbase is excited to announce a partnership with HackerOne, a platform that enables organizations to host bug bounty and vulnerability disclosure programs. Now, white hat hackers from across the world will be able to receive payment for their work in bitcoin. Programs hosted on HackerOne include Yahoo!, Twitter, and Square.

The benefit is clear for these researchers. Bounty winners who select bitcoin as their preferred payout option not only receive their payment at lightspeed compared to traditional payment methods, but also receive up to a 5% higher payment thanks to savings passed on from drastically reduced fees.

The launch of this partnership is particularly exciting given our recent international expansion. Recipients of bitcoin in the United States and in more than 18 Eurozone countries can now easily convert their payout to dollars or Euros.

Part 3/3 Owning Intelligence Series: How Coinbase Built, Evaluated, and Post-Trained a Fraud Agent

Yao Ma, Xuwei Tan, Akshit Trehan, Aman Choudhary, Anyscale Team: Eric Tang, Sumanth Hegde, Seiji Eicher, Jess Kong

TL;DR: Using SkyRL on Anyscale, we post-trained Qwen3.5-9B for Onramp fraud detection and served it with Ray Serve LLM and vLLM. On our benchmark, it exceeded Opus 4.5 across all four detection metrics, including 9.6% higher F1. In online inference, we reduced end to end latency by 55%.

TL;DR: Newer LLMs are not necessarily better at domain-specific tasks. On our fraud benchmark, newer Opus, Sonnet, and GPT versions all had lower recall, F1, and dollar-weighted recall—even when precision improved. The lesson: choose models using high-quality, domain-specific benchmarks, with reproducible evaluation and ideally deterministic scoring against verified outcomes. These findings also motivated our next step: post-training open-weight models for greater control over quality, cost, and deployment.

Migrating 300+ namespaces from self-hosted Temporal to Temporal Cloud

Ian Yap

Oct 1, 2026

TL;DR: We moved more than 300 Temporal namespaces, across more than 300 services, from a cluster we ran ourselves onto Temporal Cloud. You cannot finish the move by repointing services at Temporal Cloud while workflows are still running on the old one. Where teams could pause new work, we waited for in-flight runs to finish and then switched; for trading, payments, and long-running work, we ran the old cluster and Temporal Cloud, and moved new workflows over in steps, with rollback as a config change. Private connectivity, per-namespace service allowlists, and encrypted payloads were in place before the first production namespace moved.
