Public permissionless blockchains facilitate peer-to-peer digital transactions, yet face
performance challenges, specifically minimizing transaction confirmation time to decrease …

The first SCION book, published in 2017, summarized the results of eight years of work by
over a dozen researchers. Now, five years later, we have completely rewritten the book. It …

Most permissionless blockchain networks run on peer-to-peer (P2P) networks, which offer
flexibility and decentralization at the expense of performance (eg, network latency) …

Blockchain allows to securely store, using cryptography functions, validated transactions
and other data across its peer to peer (P2P) network. This P2P network is generated and …

Over the past decade, the Bitcoin P2P network protocol has become a reference model for
all modern cryptocurrencies. While nodes in this network are known, the connections among …

A recent spam wave of IP addresses in the Bitcoin P2P network allowed us to estimate the
degree distribution of reachable peers. The resulting distribution indicates that about half of …

Once deployed, a decentralized blockchain system ensures that it will operate faithfully so
that no one can interfere with or manipulate its predefined regulations, such as block size …

The Bitcoin peer-to-peer network ensures the consensus between the different nodes
responsible for the propagation of the blocks containing the validated bitcoin transactions …

Bitcoin was launched in 2009, becoming the world's first ever decentralized digital currency.
