We correct the double spend race analysis given in Nakamoto's foun-dational Bitcoin article and give a closed-form formula for the probability of success of a double spend attack using the… (More)

We review the so called selfish mining strategy in the Bitcoin network and properly evaluate the cost of the attack and its profitability. The expected duration of the attack has been ignored in the… (More)

Bitcoin is the first decentralized peer-to-peer (P2P) electronic currency. It was created in November 2008 by Satoshi Nakamoto, the pseudonym of the anonymous author or group of authors of the… (More)

We propose a decentralized routing algorithm that can be implemented in Bitcoin Lightning Network. All nodes in the network contribute equally to path searching. The algorithm is inspired from ant… (More)

We present Bitcoin Security Tables computing the probability of success p(z, q, t) of a double spend attack by an attacker controlling a share q of the hashrate after z confirmations in time t.
