The Jetsam Creator Contest is cancelled. In three weeks: no videos, no replies, even from the 50 top mining accounts on X we contacted. Asking creators to promote us was probably a bad idea. No prizes; the coins at stake will go to something more useful. #Jetsam #JTM

Jetsam Creator Contest: 2 days left. The deadline is extended to 4 Nov 2026, 23:59 UTC. Post your public YouTube link in #creator-contest on Discord: discord.gg/yjNgkyEw2W #Jetsam #JTM

Jetsam v1.6.1 is out — a maintenance release, not another hard fork. Pins blocks 46,079/46,080 into the node, closes a small networking edge case, and fixes a remotely-triggerable crash in the gossip layer (reported by a community member, thank you 🙏). github.com/jetsam-chain/jets… #Jetsam #JTM

Since v1.5, every Jetsam block had room for one client proof. From block 46,080, that single slot carries a batch: up to 97 client proofs folded into one, checked by the chain as a single object. What changed, and why a batch instead of a bigger slot: jetsamchain.com/blog/the-bat… #Jetsam #JTM

Jetsam v1.6.0: the hard fork took. Block 46,080 crossed 29 Oct 2026 ~21:50 UTC — 4 seeds agree, no stall. Client proofs now batch together, up to 97 per block: jetsamchain.com/blog/the-bat… Still on v1.5.x? Update now or you're mining a dead branch. github.com/jetsam-chain/jets… #Jetsam #JTM

We rebuilt the first page of jetsamchain.com for newcomers: one headline, a live block height, five plain figures and all our community links in one place. clearer, more understated, more comprehensive jetsamchain.com #Jetsam #JTM

A member of our community Suffix [Thanks to him.] Started a post asking @safetrade to consider JTM. Thank you for the support. If you'd like to add your voice, like it here: discord.com/channels/3985489… #Jetsam #JTM

The Jetsam web wallet is live: wallet.jetsamchain.com. Create or open a wallet, receive, send, or watch an address read-only. Non-custodial: keys stay in your browser, and each payment's proof is computed there. Open source: github.com/jetsam-chain/jets… #Jetsam #JTM #blockchain

The Jetsam whitepaper is on the site in English, French, Spanish, Russian and Chinese, and in a public repo under CC BY 4.0 with SHA256SUMS. English is the reference. github.com/jetsam-chain/whit… #Jetsam #JTM

Whitepaper v3.1, the figures since block 38,400: 180 s blocks, 480 a day, 25 JTM each, finality 8 blocks (about 24 min), 21M cap, emission ends at block 3,467,664. Dev fund 747,000 JTM (3.56%) until block 369,600. jetsamchain.com/whitepaper/ #Jetsam #JTM

One section we insisted on: "What we do not claim". The v1.5 client proof is not zero-knowledge. Transactions are transparent, privacy is not claimed. v1.6 is on testnet, with no date. jetsamchain.com/whitepaper/ #Jetsam #JTM

The v1.5 switch, told as it happened: block 38,400 on 13 Oct, 180 s blocks, then about 70% of the network left on v1.4.3 and the v1.5.1 fix that pinned blocks 38,399 and 38,400. It is all in whitepaper v3.1. jetsamchain.com/whitepaper/ #Jetsam #JTM

Every number in the Jetsam whitepaper carries a tag: [code], [chain], [measured], [derived] or [estimate]. You see at a glance whether a figure comes from the source code, the chain, a measurement, a calculation or a guess. jetsamchain.com/whitepaper/ #Jetsam #JTM

Jetsam whitepaper v3.1 is out, now with its own page in 5 languages and its own repo. v1.5 rules since block 38,400, the crossing and the v1.5.1 fix, live figures re-read on 15 Oct. Every number is tagged so you can check where it comes from. jetsamchain.com/whitepaper/ #Jetsam #JTM

Jetsam blocks now take 180 s instead of 90 (since block 38,400): the proof got bigger, so the interval had to move. Reward stays 25 JTM, but 480 blocks a day means about 12,000 JTM/day instead of 24,000. The 21M cap does not change. jetsamchain.com/blog/why-180… #Jetsam #JTM

Jetsam v1.5.1 is out. Everyone updates, from v1.4.3 or v1.5.0: nodes, pools, exchanges, explorers, miners, Desktop. No new fork height. It fixes the sync stall caused by the old-rules branch. Same data folder, wallet kept. github.com/jetsam-chain/jets… #Jetsam #JTM

Jetsam v1.5.0: every block gets a slot for one client proof, checked by all nodes. Mainnet hardfork at block 38,400 (est. Tue 13 Oct ~19:40 UTC), blocks become 180 s. Nodes, pools, solo miners, Desktop users: update before the fork. github.com/jetsam-chain/jets… #Jetsam #JTM
