Bitcoin mining difficulty has adjusted to 392,963,262,344.3704, constituting a shocking 16.64% leap above the previous level; for context, only two adjustments during the preceding fiat winter had a larger delta. While the network is close to completing its third exahash, more blocks at this level are needed for a confident estimate.

The Bitcoin mining difficulty has started off the fiat year with its sixth consecutive rise, reaching a value of 336899932795.8077; this being ~6.05% above the previous value, and corresponding to a network hashrate of roughly 2.4 EH/s.

On the first day of the third year of the Bitcoin Foundation's existence, mining difficulty dropped for the second time since the second halving, this time by 1.90%; the new parameter, 253,618,246,641.4895, is still 18.8% above the last measurement observed before the halving.

The Bitcoin network mining difficulty has risen to 258,522,748,404.5154 which is  7.17% higher than the previous value of 241,227,200,229.991 in this sixth increase, the seventh adjustment following the second halving. The 500-block window estimate of hashrate did rise above the two exahash mark during this period, although the ultimately resulting adjustment only corresponds to a mere 1.82 EH/s.

Continuing the recent trend, mining difficulty has climbed to 241,227,200,229.991, an increase of 6.82% above the previous value. For perspective, the net increase since the recent halving is only 12.99%, less than what has been previously covered in a single leap. Miner revenue from transaction fees has kept growing since then, reaching 806.50601126 bitcoins in the last adjustment period. This comprises 3.10% of the total mining rewards, and corresponds to a mean price of 54.2 satoshis per byte for a piece in our chain.

For the fourth time since the recent halving, miners watch their expected revenue ebb further as difficulty roses to 225,832,872,179.4596, an increase of 2.3% since the last adjustment. Hashrate estimates similarly rose above 1.9 EH/s several hours before the adjustment. Peace in our mines!

The mining difficulty has risen to 220,755,908,330.3723, which is 1.56% above the previous value, corresponding to a network hashrate around 1.6 EH/s.

For the second time in 2016, the Bitcoin mining difficulty has dropped: this time, to 178659257772.5273, merely one basis point below the previous value, and leaving the network hashrate estimate unchanged at just below 1.3 EH/s.

After an eight month streak of hashrate increases, raising difficulty by a total of 231%, the mining difficulty has dropped to 158,427,203,767.3917 (3.1% below the previous adjustment, placing total network hashrate estimates around 1.2 EH/s). During this adjustment period, unknown actors flooded memory pools with several dozen megabytes of spam. Unlike last time, when the spammers made grand claims from behind meaningless pseudonyms, they have remained anonymous this time around; and unlike previous attacks, which merely contributed to demand for block space, this one caused immediate economic consequences, as disclosed previously. The transaction fee total climbed to 726.63690949 Bitcoins, comprising 1.42% of total miner income.
