ZedarMC

Deployed Cryon as the network’s core runtime.

ZedarMC runs on my Cryon module framework, so most of my work here lands in the framework itself: feature flags, network-wide maintenance mode, the server registry and player routing across the sharded backend, and the Velocity proxy loader. Read the full Cryon write-up →

Built Cryon-Filter to replace the old chat filter.

Two tiers: swear categories each player can switch off, stored network-wide, and a slur tier nobody can. Matching runs an Aho-Corasick automaton plus hand-written fuzzy search instead of regex, about 28 µs a chat line against roughly 3,800 rules, and sign edits are dropped at the packet layer before the block is ever written. /punishwhosaid sweeps everyone who recently said a phrase.

Built Cryon-Visibility, a vanish that looks like a real disconnect.

Leave message, shrinking tab list, lower server-list count, and a /msg that answers “not online”. The server treats a vanished staffer as a spectator while their client stays in creative, so mobs, villagers and trial spawners ignore them with no packet sent. Read the full breakdown →

Shipped a Towny claim tool.

Select land with a shovel, see ghost-block outlines, confirm in a dialog on Java or a form on Bedrock. Outlines are block-change packets sent only when the selection, the claim map or the ground under you changes, a flood fill rejects selections split by someone else’s land, and outposts claim in two phases so a multi-chunk outpost costs one slot instead of one per chunk.

Built network-wide presence in Cryon-Commons.

Pub/sub carries joins and quits in about a millisecond, and each server’s own Redis hash with a heartbeat TTL repairs anything pub/sub dropped. Every server holds an in-memory roster of the whole network, so /msg resolves instantly and a crashed server’s players expire on their own.

Built Cryon-Metrics.

A metrics module that writes into the SQL database Cryon already owns, so Grafana reads it straight out. It counts a session once even when a player hops between servers, gives Bedrock players a third session scope captured inside Geyser (device, input mode, logins the proxy never saw), and tracks server health, the Vault economy and real-money Tebex revenue. Eleven tables, seventeen dashboards, five alert rules.

Hardened player data and the economy.

Player data preloads before login so joining is a cache hit, concurrent loads of one player share a single database read, and a failed save stays dirty until the write lands. Sell payouts batch once a second, with balances counting what’s still pending so nothing can see the gap.

Wired a WorldGuard addon into Cryon.

Cryon-WorldGuardAddon adds three region flags (mace-use, spear-use, wind-charge-use). WorldGuard seals its flag registry the moment it enables, which happens before any Cryon module’s onLoad, so the addon claims its flags in the earlier preLoad phase instead.

Shipped features and fixes across the Zedar plugin fleet.

Capturable outposts that pay out on an interval, crash-safe crop regrowth, a module loader where one failed module no longer stops the rest, metric hooks in ZedarCore, Paper 26.2 compat fixes in ZedarDrops, and admin-menu work in zedar-vault.
