# #001: The XE Lattice, signed blocks, a first explorer

_16–22 Feb 2026_

The first build of the network: a chain for every account, every block sealed by its owner, and representatives who vote only when an account contradicts itself.

## A chain for every account

**New** · Protocol

The **XE Lattice** gives every account a chain of its own, so accounts never wait on each other. Blocks are written in one exact format on every node and sealed with **XE Signatures**.

## Consensus only when it’s needed

**New** · Protocol

When an account signs two conflicting blocks, representatives vote with the weight delegated to them, and the block with two thirds of it wins. The rest of the time, nobody votes at all.

## New

- **Protocol:** **XE Proof of Work** on every block, to keep the network free and spam expensive
- **Protocol:** Delegation, with voting weight tracked per representative
- **Network:** Blocks and votes shared across the peer network, and local peers found on their own
- **Network:** Sync that brings a new node up to date from the tip of every account
- **CLI & API:** A REST API for accounts, blocks and pending sends, and a CLI to send, receive and check a balance
- **Explorer:** A first block explorer and wallet in the browser
