We're tracking provably lost bitcoin through publicly available logic. Discussion about proposals for this logic happens in GitHub issues and are added and amended via pull requests.

Coin is provably lost several ways. It can be lost by miners not accepting all available rewards. For example, in block 501,726 the miner didn't accept the 12.5 BTC block reward. Coin is also provably lost by users creating transactions which cause resulting coin to be unspendable. For example, the now defunct MtGox exchange made 497 BTC unspendable amongst a set of malformed transactions. Bitcoin can also be lost in more esoteric ways due to quirks of the underlying software such as the coinbase reward in the first block which is unspendable, although these remain rare.
