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

Jetsam v1.6.0 is a hard fork at block 46,080: around 29 Oct, about 22:10 UTC (estimate). Client proofs aggregated in batches, faster mining start in Desktop, consensus rule updates.
Update your node, Desktop and miners before the block. github.com/jetsam-chain/jets…
#Jetsam #JTM
Reminder: if your node or miner is still on v1.5.x when block 46,080 passes, it follows a branch of its own and no longer receives the real chain. Update to v1.6.0 first, check the file against SHA256SUMS. github.com/jetsam-chain/jets…

Jetsam Creator Contest: test the v1.5 release, film it on YouTube, win JTM. 15,000 / 10,000 / 5,000 JTM plus a 5,000 JTM Golden Globe voted by the community. YouTube only, deadline 1 Nov 2026. Details and rules: discord.gg/yjNgkyEw2W #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

⛏️ 硬核 CPU 挖矿新秀：JETSAM ($JTM) 项目解析 & Gozero 矿池保姆级挖矿教程！
🚢近期备受关注的 JETSAM ($JTM) 是一条主打「历史有界验证（History-Bounded Verification）」的创新 PoW L1 公链。
它通过递归证明将节点历史同步复杂度降至 $O(1)$，无需重放全部创世历史即可验证全网状态！
🌟 项目核心亮点：
🔹 纯粹公平：总量硬顶 2,100 万枚，0 预挖（Zero Premine）
🔹 CPU 友好：采用 TowerWalk 算法（512 KiB L2 缓存工作区），抗 GPU 算力垄断，普通家用电脑 CPU 即可参与
🔹 前沿密码学：基于 FRI-Binius 与 Poseidon2b 哈希零知识证明授权交易，具备抗量子特性
📖 Gozero 矿池 ($JTM) 3 分钟上手教程：
1️⃣ 准备钱包
下载官方 Jetsam v1.5.1+ 桌面钱包，生成以 j1... 开头的收款地址（务必备份好密钥）。
2️⃣ 启动挖矿（推荐两条路径）
• 懒人一键挖矿：下载 Gozero Assistant 2.0（Gozero助手），软件已内置最新 Gozero JTM CPU 内核并默认对接矿池。打开软件 ➔ 选择 JTM ➔ 粘贴 j1... 地址 ➔ 一键开挖！
• 命令行挖矿：访问矿池页面查看「开始挖矿」连接参数，使用官方 TowerMiner v0.3.1+ 指向 Gozero 矿池端点即可。
3️⃣ 算力调优小贴士（重要！）
由于 TowerWalk 算法吃 CPU 缓存（512 KiB/线程），开启全部超线程（100%）可能会导致缓存争用反而降低算力。建议在 Gozero 助手内对比不同线程数，找到最高算力档位！
4️⃣ 监控与收益结算
Gozero 矿池采用 PPLNS 支付模式。随时访问矿池看板输入地址，即可查询实时算力与打款记录！🔗 Gozero JTM 矿池直达：pool.gozero.trade/JTM?lang=z…

#JTM 这个算法我测试了几天、主要参考点矿工须知：
1、JTM吃CPU二级L2缓存
2、JTM吃内存频率、所以反而在MAC MINI 统一内存芯片上效率最高！
3、综合算下来、M2有6-7K算力 M3 有7-8K M6 应该有10K以上算力、而7900X 7950X 反而只有20多K算力、这个算法把吃L2缓存集写死了、目前还没有能很好提升算力的方式。

A blockchain that never gets heavier 🪶
Every @jetsamchain block carries a recursive proof of the whole chain, so a new node checks one proof plus the last 8 blocks. CPU mining, 21M cap, zero premine. Our explainer:

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
