NovaBlock.

NovaBlock was the Bitcoin mining poolMining poolA group of miners who share the work of finding blocks and split the rewards, so each gets paid steadily instead of rarely. of NovaBlock Technologies Co., Ltd. In 2020 the company said it was based in Hong Kong, with offices in San Jose in the United States, Calgary in Canada and Beijing, and that it also built data centres and developed mining chips; a year earlier the pool had given San Jose as its headquarters. It found its first block, 590,069, on 14 August 2019. Over its 18 months it found 968 blocks, about 1.2% of all blocks in that time.

It paid its miners by a scheme it called NovaPPS+: a set amount for each piece of work a miner sent, covering both the new bitcoin and the transaction fees, whether or not the pool found a block. Payouts went out once a day. So each NovaBlock block’s first transaction paid the whole reward to a NovaBlock address, and the pool paid its miners separately. These are payments to the pool’s miners, separate from the transactions confirmed inside the block. Its miners also earned Namecoin, a separate coin mined with the same work.

From November 2020 its blocks carried the words “taprootTaprootA 2021 upgrade that added Schnorr signatures and addresses starting bc1p, making complex payments cheaper and more private./bip9”, a public message of support for Taproot, an upgrade to Bitcoin’s rules that took effect in November 2021. On 5 February 2021 NovaBlock announced that Poolin, then one of the largest pools, was acquiring it, and that from 8 February all its miners’ computing power would switch to Poolin automatically. NovaBlock found its last block, 672,523, on 28 February 2021.
