TensorCash v1.2.2 is out. Thanks to Tiger, Aria and LetsG for the inputs and contributions. New: an experimental SGLang miner integration to broaden inference-provider reach, faster and more efficient pool verification, and a round of security hardening.

v3 proof sunset: from block 27,615 (expected 12:00 to 13:30 UTC today) only v4 proofs are accepted. We still see producers on v3. Check your miner is upgraded now. Final v1.2.1 is out with stricter verification from 27,615. Block producers: upgrade before the sunset.

TensorCash v1.2.0b is out. It adds 25 blocks to the transition: pricing (Y) moves from block 26,925 to 26,950 and the v3 sampling tolerance is restored, so the v3 to v4 handover does not cost miners work. On 1.2.0 or 1.2.0a? Update to 1.2.0b. Not upgraded? Go straight to 1.2.0b.

TensorCash 1.2.0 activation today at block 26,925 (expected between 14:00 and 18:00 UTC). Please update your core node, wallet, explorer and web-wallet backend. Pools and exchanges have upgraded or are upgrading now. Nodes that are not upgraded will fork at 26,925.

Proof v4: the intelligence multiplier. Difficulty that reflects how the model generates. PR #13 is open for review: git.tensorcash.org/tensorcas… Planned rollout: bcore + verifier tomorrow (14 Sep), pricing Tuesday (15 Sep), transition ends 20 Sep.

TensorCash v1.2.0 is out: Proof v4, the intelligence multiplier. Difficulty that reflects how the model generates. Pools, nodes and verifiers: upgrade before block 26,825; everyone before 26,925 (Tue 15 Sep). Binaries and wallets land on the release page as CI builds them.

StepBind grace period ends tonight, 23:59:59 UTC (8 Sep). After that, mining proofs without the StepBind flag are invalid and those blocks are rejected. Node operators, miners, pools: run v1.1.4c now. About half of the blocks mined in the last 24 h still carry legacy proofs.

TensorCash v1.1.4 is out: a consensus tightening, activating at mainnet block 24,735 (~15:00 UTC today). Block producers — pools and solo miners — must upgrade before then, or risk producing or building on an invalid block. Pool participants can update at their leisure.

TensorCash v1.1.3 is out. VDF makes the network more secure — and it doesn't have to cost you anything. We now run an optional, verifiable central VDF beacon any miner or pool can use. Chainwork amendments under consideration for a later release. Happy mining.

Block 24,000 is in. Its hash drew blocks 1039, 683, 1439 and 246. Those four addresses and the genesis key have signed the Decentralisation Day statement; the hash is committed on-chain in block 24,235. Draw, signatures and txid are on the post. Don't trust — verify.
