Hashcash HASHCASH

Memhash's Telegram channel announced the launch of Hashcash mining on 12 March 2025. The posted settings were a total supply of 150,000 Hashcash, blocks about every 3 seconds, 400,000 blocks in all, a starting reward of 0.1 Hashcash per block and a run of about two weeks. On 27 March 2025 the channel said all 400,000 blocks had been mined. In the claiming phase that followed, users could swap their Hashcash 1:1 for USDT or claim it as a token, and the project said unclaimed tokens would be burned. It also said the STON.fi pair would start with roughly 70,000 Hashcash and 70,000 USDT. Trading on Blum and STON.fi opened on 9 April 2025.

Hashcash is the name Memhash gave to its on-chain mining phase. Memhash describes itself as a mining simulation game inside Telegram, run through the @memhash_bot bot, where users earn rewards through mining similar to Bitcoin. In a listing notice dated 26 February 2025, Bitget wrote that the mining phase would end and the focus would shift to custom blockchains, the first being Hashcash, with experimental on-chain mining. According to KuCoin Research, in the Hashcash phase users could stake MEMHASH during the claiming phase, submit correct solutions to a smart contract and earn rewards; KuCoin cites a 150,000 USDT reward pool. KuCoin reports that a Hashcash mining testnet began in early March 2025.

HASHCASH and MEMHASH are separate jettons with separate contracts. MEMHASH is the Memhash token that Bitget listed, opening spot trading for it on 28 February 2025 at 09:00 UTC. There is also a third contract on TON, a jetton named Memhash with the symbol #MEMHASH and a maximum supply of 1,000,000,000. TonAPI lists it as mintable, and the Tonviewer explorer labels it SCAM. Because the names and tickers are close, the full contract address in the wallet or the DEX pool is what tells these tokens apart.

Memhash has presented Hashcash as the start of its own blockchain platform. KuCoin Research quotes the project saying that Hashcash mining "introduces our custom blockchain platform", which was meant to lead to community-driven custom blockchains, with integration of AI agents also planned. The TONboard wiki describes a planned layer-2 blockchain on TON and AI agents that learn during mining. A third-party research post published on Bitget News on 27 February 2025 named token-holder voting on Hashcash chain parameters as a future plan. These are the project's announced intentions as reported by these sources.
