Estranged Core Developer Gavin Andresen Finally Makes Sensible 2MB BIP Proposal! Just some spit-balling here, I'm sure I have some ordering and details wrong. Mike and Gavin argue for no limits and ~free transactions forever, regardless of the costs. Some in core suggest that if we really need to show the flexibility of a blocksize increase, 2MB could probably be sold and made safe enough (with planned future improvements) if we really had to. Gavin gets some clue and realizes no limit at all makes no sense; Mike grudgingly agrees to go along with a 20MB proposal. Miners reject that as unrealistically large. Bitcoin Founder Unmasked.

Together they have secured the rights to transmit updates to the Bitcoin blockchain across digital terrestrial television in Finland. To do so, they will use Digita, a Finnish network that provides coverage for approximately five million people—95 percent of the population, according to their estimates.

The transmissions are scheduled to continue for two months as part of a pilot program, and longer if they can find the funding for it. In addition to broadcasting transactional data from the Bitcoin blockchain, Kryptoradio plans to provide updates from the major Bitcoin currency exchanges. Bitcoin Wallet.
