Comment to the reader.
This Earth Log is the first of a new series, Earth Log Reader's Guides, addressed to readers rather than to the topics the corpus normally covers. It does not record an event, a stretch of cosmic history, or a development in human civilization. It records, instead, how to read the entries that do.
Two audiences are addressed throughout. The first is the reader living in the author's time, who will most often arrive at an Earth Log through a website, a social media post, or a video, and who will want practical orientation: what the metadata fields mean, how to verify an entry on the BSV blockchain, how the chain of entries hangs together. The second is the reader far in the future, who may find an Earth Log long after the websites, social media platforms, and search tools of the early 21st century are gone, and who may need a primer that does not depend on knowing what those things were.
The same prose is written for both. The structure of the entry separates what is universal — what every reader, in any era, needs to know — from what is specific to one audience or the other.
This entry is part of a small set of Project Reference entries that orient readers around the corpus rather than telling its story. Earth Log #0013, the first Register of Inscriptions, lists which entries exist and how to verify each one on chain. Earth Log #0014, the first Chapter Summaries, describes what each entry is about in plain prose. This entry explains how to read any of them. Together the three are intended to make the corpus navigable for a reader coming to it cold.

In earlier times, captains of ships kept journals of their voyages — the day's weather, the ship's bearings, the events that befell the crew. Aircraft of the same era carried sealed recorders that preserved the readings of a flight even when the aircraft itself did not survive its journey. The Earth Log is in that tradition. The ship is the planet. The voyage is human civilization. The log is intended to outlast its author.
An Earth Log is a single entry in a long chronological record of human life on Earth, written by one author during his lifetime, and inscribed permanently on a public, distributed ledger called the Bitcoin SV blockchain. Each entry is given a fixed structure: a heavy block of structured information about itself, and a body of plain prose. Once an entry is inscribed, the inscription cannot be altered. If the author later finds that an earlier entry was wrong, the response is not to edit it but to write a new entry that names the correction. The honest record is the full sequence, including the parts the author has since revised his understanding of.
The entries are written for two readerships at once. The first is people alive during the author's lifetime, who want a perspective on what is happening in their world and on the long arc of how it came to be that way. The second is readers — human, post-human, artificial, or otherwise — who may encounter these entries long after the civilization that produced them has changed beyond recognition or ceased to exist. The same prose serves both. The structured metadata around the prose is what allows the corpus to be navigated by either audience.
This guide explains how to read an Earth Log. It is laid out in three parts: what is universal — true for every reader of any Earth Log, in any era — and then two shorter parts, one for present-day readers and one for far-future readers, each addressing the specific questions that audience is most likely to bring.
Every Earth Log follows the same shape. The shape is intentional. A reader who learns it once can read any entry with the same eye, and a reader far in the future can read an entry of which only fragments survive and still know what part of the original they are looking at.
At the top of every entry sits a metadata block — a structured set of labelled fields giving information about the entry: who wrote it, when, in which language, where in the universe, on what topic, in what time range, classified under which categories, with which keywords, and at which addresses on the blockchain. The metadata block is heavy. This is intentional. It is the scaffolding that lets the corpus be searched, sorted, and reassembled, on any platform, in any era, by any reader. A future archivist who loads the corpus into a database does not have to read every entry to know what each one is about; the metadata answers the basic questions before the prose begins. The next section of this guide walks through the metadata field by field.
Below the metadata block, separated by a row of dashes, sits an optional COMMENT block. Not every entry carries one. When it does, the COMMENT addresses the reader directly — naming the moment of writing, flagging context the entry assumes, or explaining how the entry sits in relation to the rest of the corpus. The COMMENT is the author talking to the reader before the entry begins.
Below the COMMENT, again separated by a row of dashes, sits the ENTRY body itself. This is the prose. The prose is written to stand on its own, meaning that even if every line of metadata were stripped away, the entry would still read as a complete piece of writing. Some entries are short. Some run to several thousand words. The length is decided by what the topic asks for, not by any external rule.
After the prose, an entry closes with a small signature block giving the author's name, the project's name, the planet, and the year. The signature is the standpoint marker for the entry — a reminder that the words above were written from one person's vantage point at one fixed moment.
Some entries carry a REFERENCES section between the prose and the signature. This is the entry's bibliography, used in entries that draw on external sources — scientific papers, books, public statements, recorded interviews. Bibliographic references are numbered in the order they first appear in the prose. They are entirely separate from the References metadata field higher up, which lists other Earth Log entries this one builds on. The two have the same name and different roles: the metadata block's References points at sibling entries in the corpus, and the bibliography points at sources outside it.
This is the full anatomy: title, metadata, optional COMMENT, ENTRY body, optional REFERENCES, signature. Every entry. Every era.
The metadata block is not decoration. It is the part of the entry that answers, in plain structured form, the kinds of questions a thoughtful reader brings to any document: who wrote this, when, where, about what, in relation to what else, and how do I know it has not been tampered with. The fields are explained below in the order they appear in the inscription. The exact set of values that any given field can hold is not enumerated here — that information is part of the project's evolving conventions, recorded separately and updated as the corpus grows.
EL-ID. A four-digit number, unique to the entry, assigned in the order the entry was written. The first Earth Log is #0001. The numbers run in sequence. An entry's EL-ID is its everyday name — when one entry refers to another, it does so by EL-ID, written with a hash sign and the four digits.
Title. A short descriptive title, chosen by the author, naming the entry's topic.
