Trinity v0.1.0-alpha.36 "Lynn Margulis"

This Trinity release goes out under the name "Lynn Margulis".

It adds new features such as writing metrics to an InfluxDB database. It also adds support for the admin_peers RPC endpoint, the eth/65 protocol, a new sync mode header (comparable to light sync but on the ETH not LES network) as well as several beam sync improvements. More below the break.

With each release we like to highlight one of the amazing women from history and present day. Meet Lynn Margulis:

Lynn Margulis (born Lynn Petra Alexander;[2][3] March 5, 1938 – November 22, 2011)[4] was an American evolutionary theorist, biologist, science author, educator, and science popularizer, and was the primary modern proponent for the significance of symbiosis in evolution. Historian Jan Sapp has said that "Lynn Margulis's name is as synonymous with symbiosis as Charles Darwin's is with evolution."[5] In particular, Margulis transformed and fundamentally framed current understanding of the evolution of cells with nuclei – an event Ernst Mayr called "perhaps the most important and dramatic event in the history of life"

With each release we like to highlight one of the amazing women from history and present day. Meet Beatrice Worsley:

The first female computer scientist in Canada. She received her Ph.D. degree from the University of Cambridge with Alan Turing and Douglas Hartree as advisers, the first Ph.D granted in what would today be known as computer science. She wrote the first program to run on EDSAC, co-wrote the first compiler for Toronto's Ferranti Mark 1, wrote numerous papers in computer science, and taught computers and engineering at Queen's University and the University of Toronto for over 20 years

Trinity v0.1.0-alpha.28 "Hedy Lamarr"

This Trinity release goes out under the name "Hedy Lamarr".

Beam Sync has now reached the status: Working Prototype 🎉 (aka~ it usually works on my computer ™️ ). The impact is that now it now takes under an hour to go from an empty database to executing current mainnet blocks! Read below for more.

With each release we like to highlight one of the amazing women from history and present day. Meet Hedy Lamarr:

At the beginning of World War II, she and composer George Antheil developed a radio guidance system for Allied torpedoes, intended to use frequency-hopping spread spectrum technology to defeat the threat of jamming by the Axis powers. Although the US Navy did not adopt the technology until the 1960s, various spread-spectrum techniques are incorporated into Bluetooth technology and are similar to methods used in legacy versions of Wi-Fi. This work led to their induction into the National Inventors Hall of Fame in 2014.

Beam Sync will get a proper writeup soon. The gist is that Trinity starts as a stateless client, and slowly transitions to a full client over time.

Beam Sync is only one feature in a significant set of changes. Of special note are:

• py-evm upgrade: including performance improvements
• json-rpc server handles requests even if local state is missing
• peer discovery improvements

For the full list of changes, see the release notes.

We welcome folks to try out Beam Sync (it's the default sync now) and let us know your experience. For the fastest and easiest experience, try out: trinity --beam-from-checkpoint="eth://block/byetherscan/latest". There will be a lot of log spam at the console. Consider it a reminder that trinity is still in alpha. 😅

Expect another small release soon, with final Istanbul support included.

Trinity v0.1.0-alpha.26 "Williamina Fleming"

This Trinity release goes out under the name "Williamina Fleming".

Look for improvements to command line usage, logging, plugin dogfooding, and a less-crashy (but still experimental) new sync approach.

With each release we like to highlight one of the amazing women from history and present day. Meet Williamina Fleming, a:

Scottish astronomer. During her career, she helped develop a common designation system for stars and cataloged thousands of stars and other astronomical phenomena. Among several career achievements that advanced astronomy, Fleming is noted for her discovery of the Horsehead Nebula in 1888.

Of special note is trinity --sync-mode=beam. Beam Sync now crashes so much less that it's reasonable for adventurous folks to start experimenting with it. Beam Sync downloads just enough state to run the latest blocks, and is currently the best option for executing the latest mainnet blocks with Trinity. Note that the current Beam Sync implementation does eventually fall behind and stop syncing, but there are many options for performance improvement. In the current implementation, Beam Sync can run for a few hundred blocks if you sync against a peer on localhost.
