Post mortem written on January 11, 2021 tl;dr: Someone found an exploit to create bitcoin (on the Autobahn Network) via double spend and tried to cash them out of the pool but only managed to obtain BTC worth 50$. We fixed the problem and froze the attackers accounts. On Thursday…

The Autobahn Network delivers a novel way to move other assets on the network that is used by Tixl, which offers speed and privacy. In contrast to existing solutions we don’t rely on peer to peer payment channels, nor on centralized solutions to swap tokens. The basic idea is to…

- *** Update: In a token split done in 2020, MTXLT became TXL with a split ratio of 1:1,000. The MTXLT mentioned in this article migrated to TXL.*** !!! Notice !!! The Tixl Testnet Blankenese is not yet released, but will be released soon! …

In this article we’ll briefly outline our progress and milestones for the Tixl prototype. Glossary Validator node: A node running the consensus and storing the transactions in the ledger. Accepts transactions. Gateway: The gateway accepts transactions and forwards them to all known validators. Ledger: The ledger is the sum of all transactions and…

*** Update: In a token split done in 2020, MTXLT became TXL with a split ratio of 1:1,000. The MTXLT mentioned in this article migrated to TXL.*** In this post we announce how we determined who gets a share of the Airdrop of the Binance DEX AMA and the winners…

Cryptocurrencies are decentralized, so there are many participants (or nodes, or validators), that validate the transactions. The sum of transactions constitutes the ledger and is replicated to all participating nodes. But how do they agree, which transactions happend? In Bitcoin this is decided by calculation power, but consensus protocols like…

Initial release documentation and explanation for the new serverless benchmark on https://serverless-benchmark.com/ . — Maybe you stumbled upon my first benchmark on Medium, that I released half a year ago. In the last weeks I have been working on a newer and better version of this benchmark. It aims to deal with the shortcomings of the first version. …

The Honey Badger BFT is a consensus algorithm for asynchronous environments. Most consensus algorithms rely on a synchronous networks and elect a leader. Honey Badger is especially suitable for application for blockchains, as it makes progress even under highly adverse conditions. As I first read the paper, I quickly realized that…

Important Note: Deprecated — I released a newer and more reliable benchmark on this site. We have Serverless around for almost four years now, since Amazon introduced it on the re:Invent in the end of 2014. In 2016 Google, Microsoft and IBM joined the party. …
