f2pool has made the switch from reCaptcha to hCaptcha to block malicious automated traffic, all while:

  • Maintaining user privacy
  • Supporting all regions around the world
  • Assisting accessibility challenges

Until recently, we used reCaptcha for malicious traffic mitigation. However, due to a variety of issues and concerns with user privacy, payment schemes, geographic limitations, and accessibility issues, we now support and use an alternative CAPTCHA service: hCaptcha.


CAPTCHA services, or “Completely Automated Public Turing Test to Tell Computers and Humans Apart,” help companies mitigate and block malicious automated traffic (bots) through challenges. The CAPTCHA Turing test provides a valuable…

This is the third and final post on the series diving into the concepts, data, and actionable insights of decentralization transparency on the Ethereum 2.0 Beacon Chain.

Just trust me.

How many times have we seen the assumptions of good behavior and intentions and blow up in the world’s face? The value of trust and promised guarantees in the traditional world is a heavily regulated commodity backed by hundreds of years of legal history and enforcement entities. Yet, still time and time again we’ve seen the catastrophic implications of these unfortunately fallible trust frameworks fail miserably.

This is the second post in a series diving into the concepts, data, and actionable insights of decentralization transparency on the Ethereum 2.0 Beacon Chain.

The state of ignorance in which commanders frequently find themselves as, regards the real strength and position, not only of their foes, but also of their friends.

Colonel Lonsdale Augustus Hale¹

Routine uncertainties in battlefields and the methods by which military theorists have dealt with them have spawned countless strategies which have ranged from the extremes of Sun Tzu’s² preference for spy games to Jomini’s³ meticulous reduction of chaos to information battles. Applications of modern…

Key Takeaways

  • A mining pool is not a miner
  • A mining pool does not dictate the actions of its miners
  • F2Pool is not a miner
  • F2Pool does not decide what miners do with their Bitcoin

Headlines in themselves must be short, pithy, and easy to digest. However, the shorter they are the more easily misinterpreted. Narratives can quickly spawn from pithy headlines and take on lives of their own.

Unfortunately, there was a particular case of subtle mining pool related terminology that took off on its own dangerous narrative. Let’s correct that with crystal clear transparency and important terminology disambiguations.

F2Pool is not dumping Bitcoin.

This is the first post in a series diving into the concepts, data, and actionable insights of decentralization transparency on the Ethereum 2 Beacon Chain

In 1964, sensational stories broke out about the murder of Catherine Genovese, a bartender from Queens and how 38 bystanders apparently watched and did nothing¹. Details later debunked the inaction of every witness, but the shocking tragedy led social psychologists to research and quantify the diffusion of responsibility among masses which later was popularized as the ‘bystander effect’².

Adopting this narrative, there’s a fascinating talk of “bugs in the brain” by the famed security expert…

The very first Ethereum 2.0 validator slashing occurred at Epoch 208 for Slot 6668 of the Beacon Chain. As we can see here in Slot 6669’s proposer slashings, Validator 20075 proposed two conflicting blocks for the same slot in 6668.


CosmWasm is a new smart contract platform by Confio that provides a WebAssembly (WASM) runtime through a plug-and-play module that can be easily integrated into existing Cosmos SDK blockchains. CosmWasm allows users to upload their own WASM-based smart contracts which can be written in a variety of languages, enabling the use of custom logic alongside functionality provided by the blockchain’s native modules. Terra, whose protocol enables the issuance of stablecoins pegged to various world currencies is built on the Cosmos SDK and is compatible with CosmWasm. In Terra’s next mainnet upgrade, CosmWasm will be integrated through the new WASM module…

Terra Roadmap

For the past 18 months, development around the Terra blockchain was intended to do one thing very well: retail payments for e-commerce. While this strategy was crucial to bootstrapping the adoption of the network and differentiate Terra from the dozens of blockchains without much userbase, the time has now come for Terra to transition to an open platform where it empowers developers to build game-changing applications for Terra’s now 2M strong users. Here we outline our the Terra Core release schedule, roadmap, related tooling and projects, and initiatives for the remainder of 2020 up until the launch of our fifth…

You can now store and send Terra cryptocurrencies such as Luna and TerraKRW on both Ledger Nano S and X. This means that you can use your Ledger hardware wallet to securely keep your funds and interact with the Terra blockchain. Hardware wallets are considered to be much more secure than mnemonics or encrypted files that you keep on your computer. In fact, the private keys never leave the device itself, so your digital assets are safe even when using an infected (or untrusted) computer.

Before you begin

  • Set up your Ledger Nano S/X. …
